Abnormal vascular smooth muscle cell (VSMC) contraction plays an important role in vascular diseases. The RhoA/ROCK signaling pathway is now well recognized to mediate vascular smooth muscle contraction in response to vasoconstrictors by inhibiting myosin phosphatase (MLCP) activity and increasing myosin light chain phosphorylation. Two ROCK isoforms, ROCK1(More)
Hypertension, a major cardiovascular risk factor and cause of mortality worldwide, is thought to arise from primary renal abnormalities. However, the etiology of most cases of hypertension remains unexplained. Vascular tone, an important determinant of blood pressure, is regulated by nitric oxide, which causes vascular relaxation by increasing intracellular(More)
Atrial fibrosis, the hallmark of structural remodeling associated with atrial fibrillation (AF), is characterized by abnormal proliferation of atrial fibroblasts and excessive deposition of extracellular matrix. Transforming growth factor-β1 (TGF-β1)/activin receptor-like kinase 5 (ALK5)/Smad2/3/4 pathway has been reported to be involved in the process.(More)
For understanding the pathogenesis of Down syndrome (DS), it is important to identify and characterize the genes on Chromosome (Chr) 21, especially those in the Down syndrome critical region (DSCR) on Chr 21q22.2. Recently we have determined 33.5 Mb (more than 99%) of DNA sequence of Chr 21 and, from these sequence data, we identified a novel gene, DSCR5(More)
The accumulation of single-stranded DNA-binding (SSB) proteins is essential for organisms and has various applications. However, no study has simultaneously and systematically compared the characteristics of SSB proteins. In addition, SSB proteins may bind RNA and play an unknown biological role in RNA metabolism. Here, we expressed a novel species of SSB(More)
Cyclic GMP-dependent protein kinase I (PKGI) mediates vascular relaxation by nitric oxide and related nitrovasodilators and inhibits vascular smooth muscle cell (VSMC) migration. To identify VSMC proteins that interact with PKGI, the N-terminal protein interaction domain of PKGIalpha was used to screen a yeast two-hybrid human aortic cDNA library. The(More)
The role of genetic abnormality of δ-sarcoglycan (δ-SG) gene in dilated (DCM) and hypertrophied (HCM) cardiomyopathy patients is still unfolding. In this study we first defined the promoter region and then searched for polymorphisms/mutations among the promoter, 5'-untranslated region, and the encoding exons in δ-SG gene in 104 Chinese patients with DCM,(More)
Stimulation of G protein– or tyrosine kinase–coupled receptors regulates cell proliferation through intracellular Ca ([Ca]i) signaling. In A7r5 cells, we confirmed that inositol 1,4,5-trisphosphate (IP3) mediates vasopressin (VP)-evoked Ca release from intracellular stores and showed that types 1 (IP3R1) and 3 (IP3R3) IP3 receptors were expressed.
