Research Interests

Integrative and Translational Research: stroke; hypertension; diabetic complications; cancer

Approaches: Contemporary techniques cutting-edge methodologies are used for my studies at molecular, cellular and in vivo levels, such as telemetric cardiovascular monitoring, behavior analysis, brain microinjection, cell transplantation, real-time RT-PCR, gene transfection, RNA interference (RNAi), nanoparticle tracking analysis (NTA), ELISA, western blot, etc.

Summary of My Research Emphasis

  1. Study of the role of renin-angiotensin system (RAS) in cardiovascular disease. We are currently focusing on the two counteracting RAS signaling pathways (Ang II/AT1 and Ang1-7/Mas). Gene modified mice models (transgenic or gene deletion) are used for the studies. Middle cerebral artery occlusion (MCAO) is conducted for introducing focal ischemic stroke on animals. The long-term objective is to understand the roles of different RAS pathways in regulating endothelial progenitors (EPCs), endothelial cell (ECs), smooth muscle cells (SMCs), neuronal and glial function. The blood-brain barrier (BBB) and bone marrow(BM) mechanisms are also explored.
  2. Study of extracellular microvesicles (MVs) and Exosomes in four major areas: 1) release, isolation, purification and detection; 2)  contents, modulation and function; 3) biomarkers; 4) targets for therapeutics. Accumulating evidence indicate that extracellular MVs and exosomes could be biomarkers and therapeutic targets of various diseases. The long-term objective in my laboratory is to understand the roles and mechanisms of extracellular MVs and exosomes mediated cell-cell communication in physiology and pathologies.
