Epigenetic mechanisms impart cells with new properties often by turning groups of genes on and off at a given time. A focus of the lab is studying the molecular machinery that permits cells to transmit this information (which genes are on and which genes are off) to progeny cells upon division. Another focus for the lab is cellular dormancy. Recently, scientists have discovered that a major reason for cancer resistance and recurrence is that a small number of dormant cancer cells originating from the primary tumor disperse throughout the body. These cancer cells are long-lived and can exit dormancy forming tumors years after remission. None of the existing therapies target dormant cancer cells. By studying dormancy, we strive to develop drugs that specifically neutralize these cells, which may help in addressing this unmet need in cancer therapy.
