RESEARCH INTERESTSDr. Liang's research interests are listed as follows:
1. Age-associated changes in bone remodeling activity in vivo and its cellular and molecular mechanisms in vitro
2. Age-associated alterations in osteoprogenitor cells: deficits in mitogenic activity, osteogenic lineage expression and bone induction potential
3. Growth factor, hormone and other novel therapies including MMP inhibitors for osteoporosis
4. Regulatory mechanisms of vitamin D and diets on intestinal absorption and renal reabsorption of Ca and Pi in aging
5. Cellular and molecular mechanisms for desensitization to PTH and its role in impaired Ca and Pi homeostasis in aging
RESEARCH ACTIVITIES & ACCOMPLISHMENTSDr. Liang has been an established researcher on regulatory mechanism of mineral homeostasis in aging. He is the author of 68 articles with many published in excellent journals. His more recent work on the mechanism of impaired osteoprogenitor cells in aging and its corrective remedies has lead to the development of many investigative interventions for postmenopausal as well as age-related osteoporosis.
