The primary goals of research projects in Cheng laboratory is to improve our understanding of the molecular mechanisms and signaling pathways of human cancer initiation, tumorigenesis, invasion, metastases and angiogenesis, and to develop novel approaches for anti-cancer therapies by targeting molecular pathways by which human tumors develop and progress. Our approaches include molecular, cellular biology, histology, tumor xenografts in cell culture and animals model systems of human brain tumors (in particular, glioblastomas) and breast cancers.
