Angiotensin type 1a receptor (AT1aR) is thought to play an important role in the development of hypertension. However, it is unknown how the AT1aR expression in vascular tissue is changed during the development of hypertension or if the degree of methylation in the AT1aR promoter correlates with the expression of AT1aR. To address these questions, we(More)
Ischemic injury to neurons represents the underlying cause of stroke to the brain. Our previous studies identified MG53 as an essential component of the cell membrane repair machinery. Here we show that the recombinant human (rh)MG53 protein facilitates repair of ischemia-reperfusion (IR) injury to the brain. MG53 rapidly moves to acute injury sites on(More)
BACKGROUND Both angiotensin II type 1 receptor (AT1R) and nuclear factor-kappa B (NF-κB) play significant roles in the pathogenesis of hypertension and type 2 diabetes. However, the role of NF-κB in perpetuating renal AT1 receptors dysfunction remains unclear. The aim of the present study to determine whether blockade of NF-κB, could reverse the exaggerated(More)
BACKGROUND Oxidative stress plays an important role in the pathogenesis of hypertension, especially in obesity-related hypertension. The natriuretic and antinatriuretic components of the renal renin angiotensin system (RAS) maintain sodium homeostasis and blood pressure. Here, we test the hypothesis that increased oxidative stress leads to the imbalance of(More)
