The Nefedova laboratory is interested in the molecular mechanisms that enable tumor cells to interact with their microenvironment--the conditions in which cancer cells and the surrounding tissues operate. In particular, her focus is on the Notch signaling pathway in multiple myeloma, a cancer that affects 22,000 new patients each year, and kills over 10,000.

Nefedova’s team has demonstrated experimentally how Notch and related proteins can trigger the ability of cancerous myeloma cells to resist chemotherapy. Currently, Nefedova and her colleagues continue to investigate strategies that target myeloma cells to enhance their sensitivity to chemotherapy.
