Inflammatory responses are associated with the genesis and progression of end-organ damage (EOD) in hypertension. A role for the α7 nicotinic acetylcholine receptor (α7nAChR) in inflammation has recently been identified. We tested the hypothesis that α7nAChR dysfunction contributes to hypertensive EOD. In both spontaneously hypertensive rats (SHRs) and rats(More)
This work investigated the expression of alpha-7 nicotinic acetylcholine receptor (α7nAChR) in the left ventricle and its putative role in cardiac angiogenesis in a pressure overload rat model induced by abdominal aorta coarctation. Blood pressure and protein levels of α7nAChR were measured at 4, 8, 12, and 16 weeks after surgery. mRNA levels of α7nAChR,(More)
BACKGROUND Cardiac dysfunction is well-described in endotoxemia and diagnosed in up to 60% of patients with endotoxic shock. ATP-sensitive potassium (KATP) channels are critical to cardiac function. This study investigates the role of Kir6.2 subunits of KATP channels on cardiac dysfunction in lipopolysaccharide (LPS)-induced endotoxemia. METHODS Kir6.2(More)
AIM To investigate the role of ATP-sensitive potassium (K(ATP)) channels on blood pressure variability (BPV) in sinoaortic denervated (SAD) rats. METHODS SAD was performed on male Sprague-Dawley rats 4 weeks before the study. mRNA expression of Kir6.1, Kir6.2 and SUR2 in aorta and mesenteric artery was determined using real-time quantitative polymerase(More)
OBJECTIVE To detect the gene mutations of beta-myosin heavy chain gene (MYH7) in Chinese pedigrees with hypertrophic cardiomyopathy (HCM), and to analyze the correlation between the genotype and phenotype. METHODS Exons 3, 5, 7-9, 11-16 and 18-23 of the MYH7 gene were amplified with PCR in three Chinese pedigrees with HCM. The products were sequenced.(More)
OBJECTIVE To detect gene mutations on beta-myosin heavy chain gene MYH7 in 3 Chinese families with hypertrophic cardiomyopathy (HCM), and to analyze the correlation between genotype and phenotype. METHODS A denaturing high-performance liquid chromatography (DHPLC) and sequencing mutation screening of the exons (exon3-23) coding for MYH7 gene were(More)
