Current Research
Prostate cancer is the most common non-cutaneous malignancy and second leading cause of cancer-related mortality in men of the Western world. While effective surgical, radiation, and androgen ablation therapy exists for clinically localized prostate cancer, progression to metastatic castration-resistant prostate cancer (CRPC) remains essentially incurable. Despite the success of recently approved therapies targeting AR (androgen receptor) signaling, durable responses are limited due to acquired resistance. Therefore, the identification and therapeutic targeting of co-activators or mediators of AR transcriptional signaling should be considered as alternate strategies to treat CRPC. Our research is focused on chromatin modifying enzymes and chromatin-associated epigenetic regulator proteins in the context of prostate cancer initiation and progression to metastasis.
Current areas of interest within the laboratory include:
1. Delineating the role of chromatin regulators, and its importance in AR mediated transcription
2. Understanding the role of non-coding RNA in regulating higher order chromatin structure
3. Investigate the molecular mechanisms of resistance to targeted therapiesAsangani Lab
Cancer cells display an altered landscape of chromatin leading to broad changes in the gene expression. In addition, genes involved in chromatin remodeling and epigenetic regulation are frequently and specifically mutated in a wide variety of cancers including prostate cancer. While known to serve important roles in the control of gene expression and development, these largely unexpected mutation findings have illuminated newly recognized mechanisms central to the genesis of cancer. Gaining insight into the mechanism of chromatin regulation in cancer will offer the potential to reveal novel approaches and targets for effective therapeutic intervention.
Our laboratory employs a multidisciplinary approach to study these molecular epigenetic events associated with cancer towards the overarching goal of translating this knowledge into clinical tools by developing novel diagnostic, prognostic and therapeutic strategies. Additionally, we investigate the mechanisms of resistance to targeted therapies and develop novel combinatorial approaches that act on compensatory/new pathways in resistant tumors. Our basic strategy is to develop and deploy rational polytherapy upfront that suppresses the survival and emergence of resistant tumor cells.
Postdoctoral positions are available for highly talented and motivated cancer biologists to join the Asangani laboratory. Ideal candidates will have an interest/experience in cancer epigenetics or metastasis, though extremely qualified candidates of any background in biology will be considered. Applicants must be near completion or have recently completed a Ph.D. Interested candidates should contact Dr. Asangani directly at asangani@upenn.edu and include CV, research summary, and three references.Selected Publications

Current Research
We are interested in studying the evolution of cancer development from pre-malignancy through transformation. Hematologic malignancies are an ideal disease model to study classical questions in cancer biology, given sample access and extensive description of the normal hematopoietic differentiation cascade. Genetic studies in acute myeloid leukemia (AML) have revealed a hierarchical arrangement of mutations such that certain mutations are postulated to be acquired either early or late in disease progression. This stepwise acquisition of mutations results in a genetically heterogeneous collection of clones contributing to disease development. Through the progression from pre-malignancy to leukemic transformation, we study the following broad questions:
1) What are the necessary steps for a mutant cell to transform to leukemia?
2) After transformation, how do leukemic cells affect normal non-mutated cells?
3) How can we revert or halt transformed cells early in disease development to prevent disease development?
We approach these questions through an intersection of genomic profiling of patient samples and synthetic biology approaches for modeling disease in mice
Bowman Lab
The major focus of the lab is on the receptor tyrosine kinase, FLT3, which is the most commonly mutated gene in AML and typically presents as a subclonal, late event. Mutations can manifest as internal tandem duplications (ITDs) in the juxtamembrane domain leading to constitutive kinase activation. Despite being mutated in only a subset of leukemic cells, FLT3 mutations are associated with poor prognosis. Tyrosine kinase inhibitors (TKIs e.g. gilteritinib) demonstrate substantive clinical efficacy, but invariably lead to relapse. It remains unclear when a given leukemia is dependent upon FLT3 mutations, and how a subclonal oncogene portends such poor prognosis yet has therapeutic utility. In a broader context, understanding the functional roles of clonal and subclonal mutations in AML initiation and maintenance has fundamental mechanistic and therapeutic implications. Current projects in the lab focus on:
1: Oncogenic dependency in leukemic stem cells We will seek to understand how quiescent leukemic stem cells respond to therapy by juxtaposing chemical vs genetic inhibition. In the long term seek to understand how cooperating mutations influence the quantity and characteristics of this stem cell pool.
2: Evaluating cell of origin in FLT3-driven acute myeloid leukemia. We hypothesize that different cooperating mutations influence the cell of origin of FLT3 driven disease. Our lab will approach this question using inducible mouse models and synthetic biology approaches for cell type specific control. In the long term, we seek to progress towards complete in vivo modeling through the development of novel cell type specific recombinase mouse lines.
3 : Investigate interclonal interactions in leukemic progression. We hypothesize that this stepwise acquisition of mutations results in a genetically diverse ecosystem where clones interact either in supporting or suppressing other genetically distinct clones. Our group will investigate inter-clonal interactions and competition through the lens of FLT3 mutant AML, investigating several key questions including: Does the presence of a FLT3-mutant clone affect the fitness of antecedent clones? To investigate clonal heterogeneity and paracrine interactions we will integrate single cell genomic profiling in clinical isolates and mouse models of subclonal FLT3-mutations, mechanistically evaluate candidate paracrine factors ex vivo, and evaluate their role in disease progression in vivo.

Research Interests
Our research program at Penn is founded in a new paradigm in nutrient sensing and protein regulation, termed metalloallostery, where redox-active metals control kinase activity, and is advancing our knowledge in basic science and disease-focused areas. Our focus lies at the intersection of kinase signaling and copper (Cu) homeostasis with the goal of defining the mechanistic features of Cu-dependent kinases to target them in cancer via drug repurposing or development. Kinases directly respond to and, in some cases, sense inputs, like growth factors, nutrients, and metabolites, to relay information to drive complex cellular processes. Aberrant kinase activation disrupts the balance between cell growth and cell death and in turn, can drive cancer initiation and progression. While kinase inhibitors dramatically changed the landscape of cancer treatment, emergence of resistance limits clinical durability. Our discovery that the transition metal Cu, which is acquired as a dietary nutrient and essential for life, activates the canonical MAPK pathway at the level of the MEK1/2 kinases established an evolutionarily conserved, critical mechanistic function for Cu as an intracellular mediator of signaling (Turski & Brady et al. Mol Cell Biol 2012). The direct interaction between Cu and MEK1/2 is the first example of Cu enhancing mammalian kinase activity and exposed a mechanistically distinct vulnerability that can be exploited therapeutically in cancers with aberrant MAPK signaling (Brady et al. Nature 2014). The emergence of this new clinically relevant signaling paradigm highlights the need to understand how redox-active metals interact with signaling pathways and underlines the promise of discovering new modes of kinase regulation as orthogonal therapeutic vulnerabilities.

Current Research
Maintenance of genome integrity plays a critical role in the prevention of cancer and other age-associated diseases. My laboratory studies the mechanisms utilized to safeguard the genome and investigates how failures in these processes impact tissue homoeostasis, cancer risk, and, potentially, cancer treatments. We are particularly interested in processes that maintain genome stability during DNA replication.
Brown Lab
As an essential sensor of problems occurring during DNA replication, the ATR protein kinase regulates a signal transduction cascade that preserves troubled DNA replication forks and prevents their collapse into DNA double strand breaks. The conditions that activate the ATR pathway during DNA replication include oncogenic stress, replisome dysfunction, and encounters with difficult-to-replicate DNA sequences and naturally occurring forms of DNA damage. In aggregate, such problems are relatively common. Thus, ATR pathway, as a component of a multilayered network of DNA replication and repair factors, performs an essential function in genome maintenance that influences the emergence of cancer and other age-associated diseases. Using both mouse models and cell-based systems, we are currently investigating how the ATR pathway counters replicative stress, how replication stress relates to the process of aging, and whether hypomorphic suppression of the ATR pathway may serve as an effective cancer treatment.

Current Research
My laboratory studies the mechanisms by which the ubiquitin-proteasome system (UPS) controls cell proliferation and how alterations in these processes contribute to tumor initiation and maintenance. Misregulation of protein degradation pathways is often observed in cancer cells. Integrating the study of cellular signals with the molecular mechanisms by which ubiquitin ligases target substrates will advance our knowledge of cancer biology and will provide novel avenues for development of therapeutics.
Areas of interest within the laboratory include, but are not limited to: (i) Signaling Pathways (such as those related to the cell division cycle, DNA damage response, circadian clock, and NFkB signaling) and (ii) Identification of small molecules to target ubiquitin ligases.Busino Lab
Hematological malignancies are tumors that affect blood, bone marrow and lymph nodes. Taken together, hematological malignancies account for approximately 10% of new cancer diagnoses in the United States. Drugs that target the UPS, such as thalidomide and bortezomib, improve survival, underlining the effectiveness of targeting the UPS, but resistance to these therapies eventually develops. Therefore, the identification of novel UPS enzymes that could serve as targets is crucial for the development of therapeutics.
My laboratory focuses on two main research areas:
(i) Functional discoveries in the area of ubiquitin system and hematologic diseases.
This research area aims to characterize the molecular functions of cancer associated-mutant ubiquitin ligases. Our lab combines genetic and proteomic-based approaches to identify and elucidate novel substrate-ligase pairings and their biological significance in sustaining the proliferation of cancer B-cells.
(ii) Development of high-throughput assays to identify small molecules targeting ubiquitin ligase-substrate interactions.
With this research area, we aim to establish assays to serve as a screening platform for targeting specific ligase-substrate interactions. Our long-term goal is to identify candidate molecules to test them in models of leukemia and lymphoma.Selected Publications

Current Research
The Chodosh laboratory uses genetically engineered mouse models, patient samples and bioinformatics to understand the mechanisms by which cancers develop, progress to more aggressive states, and ultimately contribute to cancer mortality. A broad array of basic and translational research approaches are used to address problems of fundamental clinical importance to cancer patients by elucidating pathways and principles common to human cancers. These approaches encompass genetics, genomics, molecular biology, biochemistry, cell biology, computational biology, functional imaging, animal studies, preclinical trials and clinical investigation. Particular areas of interest include: pathways regulating cancer development, metastasis, tumor dormancy and recurrence; the use of genomics and computational approaches to understand genetic programs in cancer; the impact of obesity on cancer recurrence; the mechanisms by which pregnancy protects against breast cancer; and the use of non-invasive imaging approaches to study tumor biology.

Current Research
Our research is dedicated to deconstructing the multistep process of tumorigenesis. The major emphasis of our laboratory is to uncover the pathways that are disabled by mutational inactivation of tumor-suppressor genes as well as those pathways stimulated by aberrant oncogene activation. Areas of interest within the laboratory include: p53-regulated tumor immune surveillance, Rb-mediated tumor suppression, chemical genetic strategies to modulate tumor suppression, development of gene regulating tools for mouse models, and Kras signaling in lung cancer.
The Feldser Laboratory
The Feldser lab uses genetically engineered mouse models to study tumor progression and metastasis of common forms of human cancer. These models faithfully recapitulate many aspects of the histopathological progression of their human counterparts. Tumors initiate within the appropriate tissue microenvironment from single cells due to induced activation of latent oncogenes and/or deletion of key tumor suppressor genes. These lesions evolve through multiple cellular states toward malignant and metastatic disease. We focus on mouse models in order to employ novel genetic tools to regulate gene function at will in developing cancerous lesions as well as track cancer growth and dissemination via bioluminescent and fluorescent techniques. We couple cellular, genomic and biochemical analyses to our powerful in vivo tools to discern the mechanics of tumor progression and metastasis with the goal of identifying new therapeutic strategies to eradicate malignant cells.

This laboratory is interested in identifying basic mechanisms involved in maintaining genome integrity and understanding their relationship to human malignancy. In particular, we are devoted to the elucidation of BRCA1-dependent signaling pathways necessary for appropriate repair of DNA double strand breaks and suppression of breast and ovarian cancer.
Key words: BRCA1, BRCA2, RAP80, BRCC36, MERIT40, Ubiquitin, ATM, DNA repair, chromatin, epigenetics, cellular senescence, Breast Cancer, Ovarian Cancer.Greenberg Lab
Germline mutation of either the Breast Cancer 1 (BRCA1) or Breast Cancer 2 (BRCA2) genes greatly predisposes individuals to breast and ovarian epithelial cancers. Clinical BRCA1 and BRCA2 mutations render cells deficient in DNA damage checkpoint signaling and error-free mechanisms of DNA repair known as homologous recombination, strongly supporting a role for these activities in tumor suppression.
Our research has contributed to the developing concept of a BRCA1-centered breast and ovarian tumor suppressor network. BRCA1 forms several distinct DNA damage inducible 'supercomplexes,' each dedicated to specific checkpoint and repair activities following genotoxic stress. These studies have provided a framework for understanding the in vivo consequences of mutations within the BRCA1 network (i.e. genes encoding BRCA1-interacting proteins) (Greenberg et al. Genes&Dev 2006). Recent work has revealed a partial molecular understanding for how BRCA1 recognizes DNA damage sites (Sobhian et al., Science 2007). We have demonstrated that an interaction between the BRCA1 BRCT domain and the RAP80 ubiquitin binding protein targets BRCA1 to K63-linked ubiquitin structures present at DNA damage sites. The RAP80 ubiquitin interaction motifs (UIMs) provide an ubiquitin recognition element to target the BRCA1 E3 ligase and a K63-ubiquitin specific deubiquitinating enzyme BRCC36 to DNA double strand breaks. Each of these activities is required for appropriate checkpoint and repair responses to ionizing radiation (Sobhian et al. Science 2007; Shao et al. Genes&Dev 2009; Shao et al. PNAS 2009; Nikkila et al. Oncogene 2009). Cancer causing BRCA1 BRCT mutants fail to interact with RAP80 and consequently demonstrate inefficient recruitment to DNA damage sites. Thus a series of ordered events involving ubiquitin recognition, breakdown and synthesis are required for BRCA1-dependent DNA damage responses. Future work will address the relationship between ubiquitin turnover and BRCA1-dependent DNA repair function. These studies should provide a detailed knowledge of the (1) molecular determinants required for BRCA1 recognition of DNA damage, and (2) how BRCA1 influences DNA repair mechanism specificity. Clinical mutations frequently disrupt these activities, thus understanding the basis for BRCA1 recognition of DNA damage should lend significant new insight into BRCA1 dependent DNA repair and tumor suppression mechanisms.
A second area of interest in the laboratory is the complex relationship between chromatin structure and DNA repair. We have recently developed novel systems to investigate interrelationships between chromatin structure and DNA double strand break (DSB) repair (Shanbhag et al. Cell 2010). Using these systems, we have shown that DSBs induce an ATM kinase dependent transcriptional silencing that spans multiple kilobases of chromatin in cis to the site of DNA damage. We intend to utilize these systems to reveal new insights into the interplay between chromatin structure and DNA repair, and how DNA repair responses influence diverse biological phenomena including cellular senescence and viral latency. We will also use these and related experimental systems to explore the molecular basis underlying epigenetic changes that occur during carcinogenesis.

Current Research
Our research focuses on elucidating the molecular mechanisms whereby menin-mediated epigenetic mechanisms in regulating endocrine cells including pancreatic beta cells, endocrine tumors, and MLL fusion protein-induced leukemia. In particular, we are interested in dissecting the function of menin, which is mutated in hereditary human tumor syndrome, Multiple Endocrine Neoplasia Type 1 (MEN1), in repressing beta cells and endocrine tumors and in promoting leukemogenesis.
1. We seek to elucidate how Menin suppresses endocrine cells, such as pancreatic beta cells, via regulating histone methylations and expression of pro-proliferative genes. We are also interested in identifying menin-regulated key pathways that can be suppressed to inhibit neuroendocrine tumors.
2. Determining how menin, which acts as a tumor promoter in MLL fusion protein-induced leukemia, cooperates with wild-type MLL protein to promote leukemia and how the menin and wt MLL axis can be suppressed to improve therapy for this aggressive leukemia.
3. Understanding how inhibition of menin leads to reversal of established diabetes in mouse models and determining whether the menin pathway could be explored to ameliorate diabetes.
4. Investigating the interplay between menin, post-transcriptional modifications of menin, and TGF-β signaling in repressing pancreatic beta cells. As both menin and TGF-β inhibit cell proliferation, we will test whether menin and TGF-β cooperate to suppress beta cell proliferation and the underlying mechanisms, using biochemical studies and mouse models.
These comprehensive approaches will provide novel insights into the molecular mechanisms for MEN1 tumorigenesis, regulation of beta cells, and leukemogenesis, shedding light on improving therapy against neuroendocrine tumors, leukemia, and diabetes.The Hua Laboratory
The research team of Xianxin Hua, Ph.D., seeks to understand how epigenetic regulations, especially those mediated by menin, control development of a variety of diseases, such as endocrine tumors, leukemia, and diabetes. His group has discovered that menin may act as a scaffold protein or a node to interact with various epigenetic regulators to control expression of genes that modulate cell proliferation and survival. They are elucidating how a cascade of the menin-mediated regulatory step is controlled at the molecular level, using a variety of approaches involving molecular and cell biology, genetics, and mouse models. They seek to help improve the treatment of the diseases by targeting the novel molecular steps.

Current Research
The pathogenesis of cancer involves not only intrinsic genetic alterations in tumor cells but also the failure of immune surveillance and unresolved inflammation. However, it is not well understood how host-intrinsic or environmental factors direct the immune response towards tumor-promoting inflammation versus anti-tumor immunity during tumor progression. In particular, mucosal surfaces exposed to the external environment are colonized by a vast number of microbes, collectively referred to as the commensal microbiota. Our work and the work of others have just begun to unveil the critical role of commensal microbiome in shaping the tumor microenvironment (TME) at the mucosal sites to regulate the tumor-immune interactions. This is as an area of tremendous opportunity for significant breakthroughs in cancer research.
The research at Jin lab lies at the forefront of: (1)Understanding how immune responses are initiated and evolve over time as tumors arise de novoand progress in the native TME; (2)Defining the molecular and cellular mechanisms by which the immune system senses and responds to microbiota-derived or tumor-intrinsic signals in the TME to regulate tumor growth and responses to therapies.
Jin Lab
We are combining multi-omics approaches, advanced imaging and mouse genetic models to address the fundamental questions in cancer immunology and mucosal immune-microbiota interaction. Findings from our research will not only advance our understanding of the fundamental immunobiology of tumorigenesis, but also provide critical insights into novel strategies for cancer prevention and treatment.
Specially, our research projects aim to
1. Elucidate the impacts of local and distal microbiota on tumor-associated immune responses in the lung.
Our current understanding about microbiota and cancer has been mostly limited to the intestinal microbiota. As a mucosal organ harboring the largest surface area in the body, the lung is exposed to a variety of air-borne microbes and also colonized by a diverse bacterial community in both physiological and pathological conditions. We have established various experimental tools to analyze and manipulate lung microbiota, and revealed their changes associated with tumor progression. Moving forward, we are working to further (1) elucidate the cellular and molecular components of the lung or intestinal microbiota that shape the TME in a spatial-temporal fashion; (2) understand how they orchestrate the balance between tumor-promoting inflammation and anti-tumor immunity to regulate tumor growth and response to therapies.
2. Reveal the spatial-temporal interactions between tumor and immune cells during cancer initiation and progression.
While intensive efforts in the field have been focused on tumor-immune interaction in established tumors, there is a critical gap in our knowledge about immune recognition and activation upon early oncogenic transformation, and about the co-evolution of immune cell populations with tumor cells during cancer progression. We have established genetically engineered mouse models that enable us to define the immune components of TME over the course of oncogenesis from nascently transformed cells to a full-blown tumor. Based on this system, we will take combinatorial approaches to perform a spatial-temporal analysis of tissue/tumor-infiltrating immune cells in regular and germ-free settings. Our goal is to understand the following long-standing questions in cancer immunology: (1) What types of immune cells interact with tumor cells at different stages of cancer development? (2) For a certain type of immune cells, do they function consistently from early to late stage, in the presence or absence of microbiota, or do they exhibit functional diversity and plasticity?
3. Define the host-intrinsic factors that shape the tumor immune microenvironment.
In addition to commensal microbiota, host-intrinsic factors are also critical in triggering immune recognition and activation in TME. While malignant transformation of epithelial cells leads to a dramatic change in their gene expression program over time and may thereby disrupt the normal immune-epithelial crosstalk, various damage or stress-associated molecules have also been implicated in the induction of innate immune response. Therefore, the goal of this project is to identify these host-intrinsic immuno-modulatory factors expressed from tumor cells or generated in the TME. We are integrating knowledge gained from the unbiased, genome-wide analysis of immune cells with the transcriptomic data of tumor cells at different time points of tumor development, and spearhead efforts in building signaling circuits and networks involved in epithelial-immune communication in a spatial-temporal fashion. Moreover, we will take advantage of the human cancer database to identify recurrent genetic alterations associated with human lung cancer, and examine how they influence tumor-immune interaction.
Altogether, we are broadly interested in understanding the mechanisms by which oncogene-driven molecular signatures, antigenic load, distinct tissue milieu and the local microbial compartment dictate the tumor-associated immune responses, and how we can target these mechanisms for more effective cancer therapies.

Current Research
The physiological effects of cancer are a manifestation of the genetic abnormalities that cause the disease. While much progress has been made in the understanding of such genetic perturbations, scientists still struggle to effectively identify, understand, and treat cancer-causing mutations. This is due to the fast-paced evolution of the disease, and the accumulation of novel mutations that permit cell survival even in the harsh environment created by a therapeutic. CRISPR is a gene-editing technology that couples the elegance of base complementarity with the enzymatic activity of a DNA nuclease in order to introduce mutations into target loci. CRISPR technologies help advance our understanding of the genetic perturbations that contribute to cancer maintenance.
Current areas of interest within the lab include: (1) Defining the functional importance of epigenetic regulators in leukemia, (2) Development and optimization of AsCas12a for multiplex genetic dropout screening, and (3) Developing new functional genomic tools.
Research Details
While whole exome sequencing of the leukemia cancer genome revealed many oncogene mutations, few of these genetic alterations lead to directly actionable therapeutic opportunities. A major objective of the lab is to annotate and dissect these genetic vulnerabilities in leukemia. To approach this, we use our highly developed domain-focused CRISPR genetic knockout screening technology, where CRISPR-mediated mutagenesis is directed to gene sequences encoding critical protein domains. This method generates a larger fraction of functional null-alleles, which increase the severity in a negative selection-based genetic screen. In contrast to RNA interference-based methods or prior CRISPR-based screening approaches, this new method is not only more efficient than other screening approaches, but also has the potential to evaluate protein domain function directly from genetic screening, and may allow high-throughput identification of protein domains that are suitable drug targets in cancer. Coupling functional genomics screening, biochemical assays, and pre-clinical mouse models, we investigate the aberrant transcription signaling networks of leukemia and explore them as potential therapeutic opportunities. Since genetic screenings are only as successful as the underlying technology, a major focus of the lab is to further optimize and expand our screening toolbox. Projects are underway to engineer different Cas proteins for multiplex genetic screening using a variety of methods, including structure-guided rational design and directed evolution. Our ultimate goal is to uncover complex genetic interactions in leukemia that are therapeutically tractable.

The Silverbush Lab
Tumors are complex and heterogeneous systems, which challenge their classification and treatment. The Silverbush lab decodes tumor heterogeneity and plasticity to understand how cancer cells transform to become more aggressive or evade treatment. We particularly examine hard-to-treat cancers with high heterogeneity, focusing on the notorious kings of heterogeneity and aggressiveness: brain cancers.
To achieve this goal, we develop and implement multi-omic single-cell tools. These tools enable us, for the first time, to simultaneously measure DNA methylation, point mutations, and transcriptional activity in the same single cells. To tackle these complex goals, we build an interdisciplinary team, welcoming MDs, biologists, immunologists, computational biologists, and pure computer scientists focusing on ML and AI. The lab encompasses wet lab and computational components, managing complex algorithmic and wet lab challenges, translational applications, and working closely with clinicians.
On-going and future projects (including rotation opportunities):
Deciphering Tumor Evolution Using Multi-omic Single Cells: Tumors are complex systems, heterogeneous on multiple levels. We can observe their patterns of heterogeneity at the transcriptomic, genetic, and epigenetic levels. However, we lack an understanding of how these levels work in conjunction or how they contribute to treatment resistance. In this project, we measure point mutations and the transcriptome from the same single cell, using the newest technique we developed, and analyze the data to uncover various layers of heterogeneity and establish connections between them.
Explore Clinical Trials through the Lens of Tumor Heterogeneity: For decades, teams have attempted to discover effective treatments for GBM and have tested therapeutics within the framework of clinical trials. Currently, no GBM clinical trial has demonstrated substantial improvement. The hypothesis is that these treatments may be effective only on a subset of patients or a subset of cells, depending on their tumor composition. In this effort, we build both experimental techniques and computational ML solutions to examine the changes in tumor and microenvironment through treatment. Specifically, we are investigating the alterations in tumor composition and the infiltration of T cells following the novel cutting-edge CART T cell therapy.
ML Solutions for Accurate Diagnosis and Prognosis: A key obstacle in cancer treatment is administering the right drug at the right time, before the target becomes obsolete. This has proven crucial in IDH mutant glioma, with the first-ever IDH mutant glioma successful clinical trials to treat these tumors showing efficacy when given early enough to patients. What is early enough? This is still largely unknown, as these tumors progress and change their composition in yet-to-be-discovered patterns. In the project, we design and implement novel ML solutions to identify the pattern of multi-omic longitudinal changes in patient samples. This approach aims to first decipher the evolution of these tumors and second, provide an actionable tool used by our collaborators around the world to obtain an accurate diagnosis and pinpoint the correct point of therapeutic intervention.

Research Details:
Chromatin - the complex of DNA and histone proteins - is the physiological template of the eukaryotic genome through which transcription factors, signaling pathways, and other internal and external cues alter gene activity and cellular phenotypes. Cancer genome studies have shown that at least 40% of human cancers harbor mutations in genes encoding chromatin-associated factors, highlighting the widespread impact of chromatin misregulation in cancer. Our research focuses on understanding chromatin function and its dysregulation in human cancer, particularly in exploring how these mechanisms regulate cellular fate transitions and plasticity that promote tumorigenic potential. In addition to our basic mechanistic discoveries, we are also committed to leveraging this knowledge for therapeutic development.Our lab currently pursues several key areas of research: (1) Investigating the molecular basis and functional consequences of cancer-associated mutations in chromatin regulators; (2) Decoding the regulation and function of chromatin-associated transcriptional condensates; (3) Examining how epigenomic reprogramming influences transcriptional and cellular plasticity to affect cancer behaviors such as metastasis; and (4) Characterizing drugs targeting newly identified epigenetic mechanisms in cancer.
Research Techniques:
We use a host of different approaches including mouse models of disease, genome-wide sequencing, advanced imaging, functional genomics, and biochemistry.
Rotation Projects:
Rotation projects are available in each area of interest in the lab. Please contact Dr. Wan for details.Selected Publications:

Current Research
Cells rely on accurate assessment of nutrient availability in order to make decisions about growth and proliferation, differentiation and function, and even their own survival. Our laboratory’s research aims to elucidate mechanisms of crosstalk between metabolic pathways, signaling networks, and the epigenome. We have a major focus acetyl-CoA metabolism, which plays crucial roles at this intersection, due to its dual roles in both lipid synthesis and as the acetyl donor for acetylation reactions. Current projects in the lab are investigating mechanisms through which metabolites are sensed and the cellular processes regulated by metabolite sensing mechanisms, the role of nutrition in regulating acetyl-CoA metabolism in different cell types and how this impacts systemic metabolic health, and how acetyl-CoA production and utilization is altered in cancer cells, exposing potential therapeutic vulnerabilities.
Wellen Lab
Growth factor signaling directs nutrient uptake and metabolism, and reciprocally, intracellular metabolite levels influence signaling and gene expression. Many critical signaling molecules and transcription factors are subject to modifications, such as acetylation and glycosylation, that are metabolically sensitive and may be altered in cancer cells.
We have recently demonstrated that acetylation of histones, and associated changes in gene expression, are responsive to glucose availability in a manner dependent on ATP-citrate lyase (ACL), a metabolic enzyme that cleaves mitochondria-derived citrate to produce acetyl-CoA in the nucleus and cytoplasm. Hence, histones can be modified in a manner responsive to nutrient availability, potentially influencing multiple chromatin-dependent processes. A major current focus of the lab is to elucidate the mechanisms through which ACL regulates acetylation and its impact on signaling and gene expression, using cancer and metabolic cell types and mouse models.
A second area of interest is in understanding the role of the hexosamine biosynthetic pathway in regulating metabolism and growth. The hexosamine pathway is a branch of glucose metabolism that produces UDP-N-acetylglucosamine (UDP-GlcNAc), a donor substrate used in the production of several types of glycans, including N-linked glycans. Many cell surface and secreted proteins are modified co-translationally by N-linked glycosylation, and these glycoproteins can be influenced by metabolic state through glucose flux into the hexosamine pathway. Changes in the function and surface expression of glycoproteins can impact tumor growth by altering cancer cells’ interactions with their environment, including their ability to respond to growth factors and acquire nutrients. We are currently investigating how the hexosamine biosynthetic pathway is regulated in cancer cells and its impact on cancer cell growth and proliferation.Selected Publications

Current Research
The Witze Laboratory is interested in studying the mechanisms by which extracellular signaling controls polarized cell behavior and how alterations in these processes contribute to tumor initiation, metastasis, and drug sensitivity.
Witze Lab
My lab has focused on the regulation of cell signaling in cancer through protein palmitoylation in response to the non-canonical Wnt signaling pathway. The goal has been to develop a biochemically tractable system to begin to understand how non-canonical Wnt signaling regulates cell polarity Treatment of melanoma cells with purified Wnt5a induces a cell polarity phenotype involving the polarized localization of the cell adhesion molecule MCAM. We discovered that MCAM is palmitoylated and Wnt5a activation induces depalmitoylation. When the palmitoylated cysteine residue is mutated to glycine MCAM asymmetrically localizes independent of Wnt5a treatment. This demonstrated a novel pathway originating with Wnt5a binding and resulting in depalmitoylation of MCAM by the enzyme APT1. We have further shown that Wnt5a signaling induces phosphorylation of APT1 on specific serine residues and this modification increases APT1 activity and metastatic behavior of melanoma cells.
A second focus of the lab involves understanding how the palmitoyl-transferase DHHC20 palmitoylates the epidermal growth factor receptor (EGFR) on the C-terminal tail and suppresses EGFR activation. Inhibition of DHHC20 by shRNA decreases levels of EGFR palmitoylation and increases the amplitude of receptor signaling when stimulated with EGF. We mapped specific palmitoylation sites to cysteine residues in the C-terminal tail. The specific palmitoylation sites that were mapped by mass spectrometry reside in exons 26 and 27 that are sometimes deleted in lung cancer and glioblastoma. Deletion of the exons activate EGFR and can transform NIH3T3 cells. We similarly found that mutating the cysteine residues in exon 26 or 27 also activate EGFR and when expressed can transform cells. We hypothesize that loss of palmitoylation is the cause of receptor activation when exons 26 and 27 are deleted. Furthermore, when the palmitoylated cysteine residues are mutated the downstream MAPK/ERK pathway is activated and cells become dependent on EGFR signaling making cells sensitive to EGFR inhibitors. Unexpectedly, we also found that in lung cancer cells harboring mutations in EGFR that impart resistance to the EGFR inhibitor gefitinib when DHHC20 is inhibited these resistant cells become sensitive to gefitinib. We think this is an unprecedented approach to target cancer cell signaling.

Research Interests
The molecular and cellular mechanisms that protect against cancer and neurodegeneration. Key words: Cancer biology, p53, tumor suppression, metabolism, autophagy, stem cells, protein quality control, aging, neurodegenerative disease
Description of Research
Our lab studies cancer and neurodegenerative disease. Our current projects focus on two broad areas:
(1) The tumor suppressor p53, metabolism, and autophagy. We are interested in the regulation and functions of the preeminent tumor suppressor p53. Our results have revealed a role for p53 in modulating metabolic pathways that are critical for biosynthesis and redox balance. We are investigating the function of p53 as both a sentinel and a regulator for metabolic activities. We are also identifying and characterizing metabolic alterations that drive tumor initiation and progression. A recent extension of this research area is to define the role of metabolism and autophagy in stem cells, including embryonic stem cells and cancer stem cells.
(2) Protein quality control, aging, and neurodegeneration. Our lab recently identified two protein quality control (PQC) systems, which consist of tripartite motif (TRIM) proteins and poly-Asp/Glu (polyD/E) proteins, respectively. Unlike canonical PQC systems, these new systems are independent of ATP and are unique for animals (the TRIM system) or eukaryotes (the polyD/E system). Both systems are multifunctional and highly effective. We are investigating their mechanisms of action; their roles in aging and neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis; and their utility in treating these diseases.

Current Research
Our lab develops computational methods to better understand how cancer develops through genetic changes and pathogenic infections. We develop integrative deep learning sequence analysis frameworks to identify new microbial sequences in cancer. We apply these methods to study microbial genes and proteins that correlate with tumor progression and with clinical outcomes.
Our lab also develops interpretable machine learning frameworks to identify treatment response biomarkers and understand the mechanisms underlying response or resistance. As a computational (dry) lab, we benefit from multiple ongoing collaborative studies, aiming to investigate microbial and genomic biomarkers of cancer treatment response and metastases.Selected Publications

Current Research
Our current research is focussed on the development of novel chemical approaches to modulate lysine post-translational modifications. This includes both synthetic and protein engineering approaches to understand lysine modifications as well as chemical biology approaches to modulate them as a potential therapeutic approach.
Burslem Lab
Post-translational modifications (PTMs) are key modulators of protein function and are crucial for the successful function of a cell. They can act as methods for signal transduction, alter the localization of a protein or signal that a protein is no longer required, as well as many other functions. The most widely studied PTM is phosphorylation of serine, threonine and tyrosine residues but reversible covalent modifications of lysine residues can have equally important functions. For example, acetylation of lysine residues is the second most observed PTM, after phosphorylation.
The Burslem lab is interested in developing chemical tools to understand and modulate lysine post-translational modifications, specifically acetylation and ubiquitination. The laboratory is particularly interested in novel pharmacological approaches to modulate post-translational modifications which regulate gene expression and protein stability with a focus on understanding and treating haematological malignancies. We employ a multidisciplinary approach including synthetic chemistry, biochemistry, biophysics and cell biology to probe biological systems in cancer biology.

Research Interest
Our lab focuses on understanding the mechanism of epigenetic dysregulation in cancer. We are particularly interested in elucidating how oncogenic signals contribute to tumor pathogenicity through epigenetic misregulation, and to leverage this mechanistic understanding for improved treatments.
The lab mainly studies cancers with frequent mutations in Notch receptor families. We use combination of wet and dry techniques to understand how oncogenic Notch drives regulatory program in these tumors. Our lab benefits from various established data-rich assays and combine them with novel technologies such as chromatin conformation and single cell genomics to elucidate the mechanisms of epigenetic dysregulation in Notch-driven tumors at both population and single cell levels.
As a member of Center for Personalized Diagnostics, we are also developing computational oncology frameworks to enrich clinical significance of diagnostic tumor genomics. Our goal is to advance the paradigm of personalized medicine by leveraging big data analytics to drive correlation between the tumor genomes and clinical covariates.

Research Interests
The research interests of our laboratory lie at the intersection of image-guided interventions, cancer and vascular biology, and molecular and advanced 3D imaging.
Cancer Biology
Interventional oncology represents the fourth arm of cancer therapy offering locoregional treatment approaches for a variety of malignancies. These approaches apply minimally invasive procedures to target cancer using percutaneous or endovascular techniques. In using imaging to directly modulate the tissue environment of the targeted cancer, these techniques provide a unique lens through which to study the tumor microenvironment. The tumor microenvironment comprises complex interactions between cancer cells and the stroma including immune cells, fibroblasts, the extracellular matrix as well as vascular networks. Our interests focus broadly on the study of the tumor microenvironment and how alterations in the tumor microenvironment affect subpopulations of cancer cells as well as how they influence the interactions of stromal cells with the tumor. Given that these are in vivo phenomena, the development of novel in vivo molecular imaging strategies is implicit in order to characterize these interactions. These studies will lead to new therapeutic targets and imaging strategies that can be applied for new and improved interventions. Current projects in the lab emphasize this goal in the context of a variety of disciplines including molecular biology, metabolism, immunology, bioengineering and imaging physics.

Current Research
Dr. Keith collaborates with Dr. M. Celeste Simon to study how cells respond to oxygen deprivation (hypoxia), which occurs naturally as tissue (or tumor) growth outstrips its blood supply. We generate mouse models in which genes encoding critical components of the hypoxic response pathway are mutated. These novel genetic tools offer unique insights into the mechanisms by which hypoxia regulates cancer cell function, and tumor growth. In addition to research, Dr. Keith coordinates the educational activities of AFCRI faculty at the medical, graduate, and undergraduate level. Most recently, Dr. Keith has developed an undergraduate course on the biological origins of cancer (Cancer Cell Biology - Biol407), which is offered annually through the Department of Biology.
Keith Lab
Dr. Keith received his Ph.D. from The Rockefeller University. He completed postdoctoral training with Dr. Gerald R. Fink at the Whitehead Institute for Biomedical Research, after which he became an Assistant Professor in the Departments of Molecular Genetics and Cell Biology, and Medicine at the University of Chicago. Dr. Keith joined the AFCRI in 1999 as Director of Education and is currently an Associate Investigator, and Adjunct Professor in the Department of Cancer Biology.
