Biography

Prof. Yoav Henis is TAU Vice President for Research and Development. In 1974 received his B.Sc. Cum Laude in Chemistry and Biochemistry at Hebrew University. In 1978 he completed his doctoral thesis at Hebrew University, under the guidance of Prof. Alexander Levitzki. This thesis won the Hebrew University Kennedy-Lee prize for best thesis of the year. Between 1978 and 1981 he was a post-doctoral fellow under the guidance of Prof. Elliot Elson, first at Cornell University (Ithaca, NY) and then at Washington University School of Medicine (St. Louis, MO). Upon his return to Israel in 1981 he became a Faculty member at the Department of Biochemistry, and then the Department of Neurobiology at Tel Aviv University.  Prof. Henis has served as the head of the Committee for acceptance of undergraduate students to the Faculty of Life Sciences (1985-7), the secretary of the Israel Society for Cell Biology (1991-5), the head of the Department of Neurobiochemistry (today named Neurobiology) (1995-8), and was a member in many University and National Committees.

 

Prof. Henis is one of the leaders in the Cancer Biophysics field. His studies combine cell biology with membrane biophysics to elucidate, in live cells, the action mechanisms of cancer-related proteins. These studies, which deal with the growth-inhibitory transforming growth factor-b receptors and with oncogenic proteins such as Ras and Src, were published in scientific journals of high standing. He is active in scientific organizations in Israel and the USA, and was a member of numerous committees and scientific forums of the Israel Science Foundation and other scientific foundations in Israel. He has won prizes and fellowships from the Bat-Sheva de Rothschild Foundation, the International Union Against Cancer, and the Jacqueline Seroussi Memorial Foundation Award for Cancer Research.

Research Interests

Our research focuses on cancer biophysics. We combine biophysical and molecular biology approaches to study the dynamics, organization and interactions of membrane receptors (e.g., TGF-b receptors) and signaling oncoproteins (Ras, Src) at the plasma membrane of living cells, with a major focus on cancer-related proteins. Our emphasis is on interactions of receptors and signaling proteins that regulate cell proliferation and cancer. The systems and topics that we study include:

 

Mechanism of cell growth inhibition and anti-tumor activity of transforming growth factor-b(TGF-b) receptors;

Disruption of TGF-b signaling by oncogenic Ras proteins and its contribution to cancer;

Biophysical studies on interactions of lipid-anchored oncoproteins Ras and Src with cell membranes and their roles in signaling & transformation;

Endocytosis of TGF-b receptors and bone morphogenetic protein (BMP) receptors and its roles in signaling via specific pathways.
