Program Leader, Cancer Epigenetics Program

Research Program

The Cancer Epigenetics Program Dr. Whetstine leads has basic, translational, and clinical research components, all dedicated to better understanding epigenetic regulation in cancer. The program’s findings will help to improve diagnosis, prognosis, and outcomes for various malignancies.

Among many professional leadership activities, Whetstine led and organized the successful 2017 Keystone Symposia on Molecular and Cellular Biology, which focused on epigenetics and human disease. He has received many invitations to speak at major conferences and institutions, serves on top-tier journal editorial boards (e.g., Science Advances) and frequently serves as a reviewer for top-tier peer-reviewed journals.

Dr. Whetstine comes to Fox Chase from Massachusetts General Hospital Cancer Center and Harvard Medical School in Boston, where he served as vice chair of the Epigenetics Program. He also held appointments as associate geneticist and associate professor in the department of medicine, respectively. 

His discoveries in epigenetics have expanded the field and provided significant implications for understanding tumor heterogeneity and drug response. In recognition of the promise of his research, he holds the prestigious Scholar award from the Leukemia & Lymphoma Society and a National Institutes of Health R01 grant, as well as funding from the American Lung Association, Alex Lemonade Stand Foundation and AstraZeneca.

Epigenetic Mechanisms Driving Copy Gain, Amplifications and Drug Resistance

  • We are asking what cellular cues or exposures are involved in driving copy gain of regions promoting drug resistance and tumorigenesis. These same questions are being extended to other clinically relevant amplified oncogenes. 
  • We are identifying all known signaling and epigenetic-related pathways involved in driving copy gain and amplifications.
  • We are identifying the epigenetic states associated with the genome that have a propensity to undergo copy number changes.
  • We are screening for factors that will allow these copy gains to be inherited.
  • We are collaborating with clinicians to establish the optimal patients for using epigenetic therapies targeting pathways promoting copy gain and drug resistance.
 
Epigenetic Mechanisms Impacting Cancer Therapy

  • We are assessing whether there are other chromatin regulators involved in protein synthesis.
  • We are determining whether other chromatin factors enhance mTOR inhibitor sensitivity or other cancer therapies.
  • We are studying other coding SNPs in chromatin modifiers that impact drug response and patient stratification.
  • We use genetic features or molecular mechanisms downstream of chromatin regulators to stratify and optimally treat cancer patients. 
 
Epigenetic Mechanisms Regulating Cell Cycle Progression

 

  • We are using next generation sequencing strategies to map the epigenome during cell cycle.
  • We are identifying chromatin and non-coding RNAs that are regulating cell cycle progression.​
