Research Interest

My research interest is “Cell Signaling and Cancer”: (1) I’m studying the molecular mechanisms that are responsible for cell cycle control and growth factor (with an emphasis on TGFbeta)-mediated growth inhibition in human myeloid leukemia cells, which involve in several cell cycle regulatory molecules and tumor repressor genes; (2) I ‘m studying the molecular events in cytokine/drug (with an emphasis on tumor necrosis factor)-induced apoptosis.
