Wei Yao, M.D.

Clinical/Research Interests

Dr. Yao received her medical degree in XianYa Medical University in China.  After receiving her medical degree she trained in Internal Medicine and practiced general medicine in China.  Dr. Yao obtained further research training in bone biology at the University of Utah.  While at the University of Utah, Dr. Yao performed a number of studies evaluating the effect of bone active agents on bone mass and turnover in rodent models.   In 2002, Dr. Yao joined the Division of Rheumatology Research Group at UCSF and her research focused on etiology and treatment of arthritis and osteoporosis.  In 2004, Dr. Yao briefly joined a research group at Stanford to study the neuropeptides’ regulation in bone turnover before being recruited, in 2005, by the University of California at Davis to be an Assistant Professor of Medicine.

Dr. Yao’s research interests include:

1.    One of my research focuses for the past nine years is to investigate if we would augment bone formation by targeted delivery of the mesenchymal stem cell (MSC) to bone.  Specifically, we have developed a technique via specifically targeting the integrin expressed in the MSCs or osteoprogenitor cells, and then conjugate the lead compounds to alendronate (LLP2A-Ale) to make them bone specific.  We have performed a number of studies to test this approach in animal models of primary osteoporosis, aging, glucocorticoid-induced bone fragility, fracture healing and in inflammatory arthritis.

2.    To invest the role of nuclear in osteoblast lineage commitment and  higher peak bone mass determination.  The outcome of this project could potentially lead to discovery of a bone specific progesterone receptor inhibitor that augments peak bone mass or to treat osteoporosis and sex does matters for bone (18-23).

4.    To understand the mechanisms for the development of glucocorticoid (GC) induced osteoporosis and bone fragility. We initiated investigations on how glucocorticoids alter cell viability via autophagy to suppress bone formation. Sustaining the level autophagy in bone formatting cells would rescue GC-induced suppression on bone formation and bone strength.  We found that osteocyte autophagy plays a major role in glucocorticoid-induced “osteocytic osteolysis” and therefore decreases localized bone material properties and increases bone fragility. We have at least two potential treatment options; sclerostin-antibody and beta- ecdysone to sustain autophagy in bone forming cells and prevent GC induced bone fragility.  These works have significantly expanded our knowledge of how glucocorticoids alter bone formation (11-17).
