Insight into the Formation and Regression of Brain AVMs from Notch4 Model of the Disease Relevant to HHT


Wang, Rong PhDRong Wang, Ph.D. is a Professor and Mildred V. Strouss Endowed Chair in Vascular Surgery, in the Department of Surgery at the University of California, San Francisco. Dr. Wang had the distinction of working as a post-doctoral fellow in the laboratory of Michael Bishop, MD, who is a winner of the Nobel Prize in Medicine and Chancellor of UCSF.

Dr. Wang's team is engaged in state-of-the-art research involving key proteins necessary for blood vessel growth (angiogenesis) and arterial growth (arteriogenesis). They have found the Notch 4 protein can cause dramatic blood vessel enlargement in adult animals and the focal adhesion kinase protein is essential to maintain existing blood vessel structure. Her laboratory was the first to publish that Notch mutations can cause AVMs in mice, and correction of a causal molecular lesion can lead to reversal of the disease progression, opening a new line of inquiry linking this disease to genes crucial for arterial-venous differentiation.


Join Dr. Rong Wang for a discussion of her recent discoveries presented at the 2015 International HHT Scientific Conference. These findings provide unprecedented insight uncovered from studying Brain AVM formation, and regression, in real time with high resolution microscopy in live animals with HHT. These studies may advance our understanding of how HHT disease is initiated and inspire new strategies in the development of treatment options.
