Dr. Gjerset's program addresses the biology of the cancer cell and the pathways involved in therapy resistance. The goal is to establish a rationale for improved therapeutic strategies for cancer and to identify biomarkers for diagnostic assays.  Her present research program focuses on a cellular protein known as p14ARF, an important suppressor of cancer cell growth,  on the regulation of the cellular enzyme, topoisomerase I, an important target for chemotherapy, and on the development of diagnostic assays for therapy resistance.  Through a cross-disciplinary effort her group is also studying a novel class of inhibitors of histone acetylation, a process that is central to cellular regulation and repair of damage to DNA.  These inhibitors hold promise as chemosensitizing drugs that could greatly improve the outcome of conventional therapies for a variety of cancers, and decrease therapy toxicity.

Biography

Ruth Gjerset earned a Bachelor's degree in Biology summa cum laude from the University of California San Diego, and a Ph.D. in Biochemistry and Biophysics from the University of California San Francisco.  She received post-doctoral training University of California San Francisco and San Diego, and at the Pasteur Institute in Paris, France.   Prior to joining the Torrey Pines Institute for Molecular Studies in 2009, Dr. Gjerset was a faculty member of the Sidney Kimmel Cancer Center where she directed a program in cancer cell biology.
