Research Interest

My research interest focuses on the cellular and molecular mechanisms underlying vascular contractility under physiological and pathophysiological conditions. I am currently investigating a novel role of ryanodine receptors released Ca2+ sparks and large-conductance Ca2+-activated K+ (BKCa) channels generated STOCs in the uterine vascular adaptation to pregnancy and chronic hypoxia. Another current research is to demonstrate the epigenetic mechanisms of myocardial infarction in adult and the susceptibility and mechanism of myocardium to ischemia/reperfusion injury in adult offspring with prenatal hypoxia exposure. These studies are to provide an initial framework and new insights into fetal hypoxia-mediated epigenetic programming of pro-inflammatory phenotype in the heart development, linking antenatal stress, and developmental programming of heart vulnerability to disease later in life.
