Dysfunctional HDL and Cardiovascular Disease

JI Program: Cardiovascular

Project Summary

Even with substantial improvements in cardiovascular disease (CVD) treatments, CVD continues to be the leading cause of death in China. Epidemiologic studies and large-scale clinical trials have conclusively established a strong inverse relationship between high-density lipoprotein (HDL) cholesterol levels and cardiovascular risk. Insight into the dynamic differences in HDL biology and function in complication prone individual will identify new diagnostic markers and therapeutic targets in subjects with CVD. To gain this insight, we propose to develop state-of-the-art mass spectrometry based platform to identify and validate novel HDL protein markers that would predict risk of endothelial dysfunction in CVD patients. The proposed study will examine the roles and myeloperoxidase (MPO)-oxidized HDL and HDL proteome in vascular dysfunction in Chinese patients, comparing this data to data collected at UMHS. 


Numerous training opportunities were derived from the collaboration, including:

  • 3 PKUHSC junior faculty members received extensive training at Michigan Medicine mentored by Dr. Eugene Chen and Dr. Sub Pennathur.
  • 3 Michigan Medicine residents completed one-month clinical rotation at PKUHSC mentored by Dr. Wei Gao and Dr. Guisong Wang.
