The faculty and Professional Staff of the SUPERS@PENN program continue to serve as mentors to me long after I finished my summer in the program. Their support was a big reason behind my decision to apply to Penn for graduate school and set my sights on a research career.
Lumena Louis – SUPERS 2010 Pharmacology Graduate Group, Univ. of Pennsylvania
By example, my SUPERS mentor taught me what it means to be a professional scientist, particularly the importance of taking ownership of my research project. The experience was extremely rewarding and helped clarify my desire to pursue a dual career in medicine and research.

Sydney Evans VMD, MS: Dr. Evans studies pathologic processes associated with hypoxia, including radiation resistance, chemotherapy resistance and tumor aggression [metastasis, invasion]). The lab concentrates on two main projects. First, Dr. Evans collaborated with Dr. Cameron Koch to develop agents for characterizing tumor hypoxia in preclinical animal models and in human clinical trials(EF5). Dr. Evans and Koch have also developed 18F-EF5 to detect tumor hypoxia by non invasive positron emission tomography (PET) imaging. Secondly, the lab has focused on the biogenesis and role of large exosomes/microvesicles (MV) in the tumor response to radiation therapy. Tumor MV have been shown to contain cargo that modulates metastasis, tumor invasion and immune system modulation. The studies in the Evan’s lab emphasize the role of the tumor microenvironment, specifically hypoxia, on MV biogenesis following radiation therapy. Dr. Evans is one of the Co-PIs on the SUPERS@PENN program grant.

Costas Koumenis PhD: Dr. Koumenis’ lab focuses on the molecular mechanisms that lead to adaptation of tumor cells to hypoxic and metabolic stress. Using targeted inhibition of the cells adaptive response to stress they hope to improve therapeutic outcomes in cancer patients. Dr. Koumenis lab was one of the first to demonstrate that hypoxia activates the integrated stress response (ISR), a coordinated cellular program that controls translation and ultimately cells survival. Specific drugs targeting components of the ISR are being closely examined to determine therapeutic efficacy. Another major project in this lab is to develop novel chemo- and radiosensitizers targeted to the molecular pathways implicated in radiation- and chemo- resistance; the lab screens small molecule libraries for compounds which have potential as response modifiers, gene therapy approaches combined with targeted delivery of drugs are also being investigated. Dr. Koumenis is one of the Co-PIs on the SUPERS@PENN program grant.

Stephen Tuttle PhD: Dr. Tuttle has been a member of the Radiobiology Division of the Department of Radiation Oncology at PENN for over 25 years. His research interests include the role of the bioenergetics and metabolomics in the cellular response to ionizing radiation and radiomimetic chemotherapeutics.

Dr. Tuttle’s current research interestsis the down regulation of cellular oxygen consumption as a mechanism of decreasing tumor hypoxia. Studies on the mechanism of respiratory inhibition by on estrogenic steroids as well as anti estrogens are ongoing.

Amit Maity MD, PhD: Dr. Maity is Professor and physician-scientist in the Department of Radiation Oncology. A primary focus of his lab is to develop ways of increasing the killing of cancer cells in response to radiotherapy by using agents that inhibit signaling pathways. Recent work has shown that agents that inhibit the PI3K/Akt/mTOR pathway lead to decreased oxygen consumption, which may result in less hypoxia within tumors and better response to radiotherapy. The Maity lab is trying to understand the mechanism behind inhibition of cellular respiration occurs and how to use this information to improve patient treatment.

Andy Minn, MD, PhD: Dr. Minn is an Assistant Professor in the Department of Radiation Oncology. His laboratory is focused on understanding how cancer cells acquire treatment resistant and aggressive metastatic phenotypes utilizing a functional genomics approach. He has identified gene expression signatures and signaling pathways that not only predict but also promote cancer phenotypes such as resistance to DNA damaging agents (chemotherapy and radiation) and aggressive organ-selective metastasis. He has discovered that signaling pathways that are normally associated with an anti-viral response are utilized by cancers to regulate many of the genes in our gene signatures, suggesting an overlap between the anti-viral response and metastasis/ treatment resistance.
