Description of Research:

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.

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 therapies
