Research Summary

Telomerase expression and telomere maintenance are required for limitless proliferation of immortal cells, including pluripotent stem cells and the majority of cancer cells.  Human telomerase is silenced during cell differentiation and consequently, somatic cells undergo finite numbers of cell division before senescing, due to their limited telomere reservoirs.  On the other hand, telomerase is activated during the progression of many types of human cancers.  Our current research projects are focused on studying the chromatin/epigenetic mechanisms of telomerase gene regulation using models of human somatic cells, pluripotent stem cells (PSCs, e.g. ESCs), induced pluripotent stem cells (iPSCs), and transgenic mice. Our goal is to dissect the critical steps and genetic elements involved in hTERT repression during cell differentiation and its activation during tumorigenesis and nuclear reprogramming.  These mechanisms are also likely to contribute to human aging.

Because telomerase activity is required for proliferation and survival of cancer cells, telomerase inhibition is an important therapeutic anti-cancer strategy.  Therefore, we will also identify small molecules that regulate telomerase activity in human cells.
