Dr. Hemler received his PhD in biological chemistry from the University of Michigan in 1978. After postdoctoral research at DFCI from 1979 to 1984, he received a faculty appointment at DFCI and was promoted to professor in 1994. He is exclusively involved in basic laboratory research, focusing on cell surface molecules that participate in cell adhesion, migration, and invasion.


Novel adhesion and palmitoylation mechanisms that regulate the tumor microenvironment

Cell adhesion is a basic process in cell biology, controlling cell growth, death, differentiation, movement, and tissue organization in normal cells, as well as the proliferation and metastasis of tumor cells. The Hemler Lab focuses on the molecular basis for cell adhesion and migration. In particular, they are interested in the structures and functions of heterodimers in the INTEGRIN family, including studies of the mechanisms whereby integrin functions are rapidly turned on and off, and different integrins link to distinct cellular signaling pathways. In addition, they study other cell surface transmembrane proteins that associate with integrins. Recent studies have shown that transmembrane linker proteins, called tetraspanin proteins, allow the membrane proximal extracellular domains of integrins to play key roles in the recruitment of intracellular signaling enzymes such as protein kinase C, and phosphatidylinositol 4-kinase.

Recent studies have focused on how certain integrins may be linked to regulation of matrix metalloproteinase (MMP) production, a key process during cell and tissue remodeling and tumor cell metastasis. Most recently, they have generated mutant mice in which the tetraspanin CD151 gene has been deleted to investigate the role of CD151 during tumor progression.
