Diabetic patients have much higher morbidity and mortality of cardiovascular diseases including atherosclerosis and restenosis compared with other populations. Vascular smooth muscle cell (SMC) migration contributes significantly to these pathological processes. Generally SMCs stay quiescent in vasculature. When the endothelium layer is disrupted, the underlying SMCs migrate from media to intima and form the neointima. This process is accelerated in diabetes mellitus (DM). Nitric oxide (NO), the biologically active component of endothelium-derived relaxing factor, has critical roles in the maintenance of vascular homeostasis. Previous studies showed that NO reduces intracellular calcium, which causes relaxation and inhibits SMC growth and proliferation in native smooth muscle. Sarco/endoplasmic reticulum Ca2+ ATPase (SERCA) plays a very important role in maintaining intracellular calcium level by uptaking calcium into SR/ER. Our previous studies showed that NO upregulated SERCA activity by S-glutathiolation of the most reactive thiol on cysteine-674 (C674) and inhibited SMC migration. My major focus is to study the mechanisms of cardiovascular dysfunction in diabetes, mainly focus on SERCA, NADPH oxidase and smooth muscle cell migration. Those studies can also be expanded to obesity, insulin resistance and metabolic symptoms.
