BACKGROUND AND PURPOSE Urocortin is a locally expressed pro-inflammatory peptide. Here we have examined the effects of urocortin on sodium laurate-induced peripheral arterial vasculitis in rats, modelling the mechanisms of thromboangiitis obliterans (TAO). EXPERIMENTAL APPROACH Peripheral vasculitis in rats was induced by sodium laurate and graded by(More)
The Ca(V)1.4 voltage-gated calcium channel is predominantly expressed in the retina, and mutations to this channel have been associated with human congenital stationary night blindness type-2. The L-type Ca(V)1.4 channel displays distinct properties such as absence of calcium-dependent inactivation (CDI) and slow voltage-dependent inactivation (VDI) due to(More)
BACKGROUND/AIMS MicroRNAs (miRNAs) have been regarded as a new class of regulators in cellular processes in non-small cell lung cancer (NSCLC). However, the relationship between miR-452 and the development of NSCLC remains unclear. METHODS qRT-PCR was used to detect the expression of miR-452 and its target gene in NSCLC samples (n=60). The transwell assay(More)
Urocortin (UCN) functions via corticotrophin-releasing factor receptors (CRFRs), CRFR1 & 2. CRFR2 is reported to be a tonic suppressor of vascularization, implying its role in tumor angiogenesis. Here, it was found that UCN inhibited the growth of hepatocellular carcinoma (HCC) and reduced tumor microvessel density in nude mice. Hepatoma cells didn't(More)
BACKGROUND AND PURPOSE Our previous study showed that urocortin (Ucn1) exacerbates the hypercoagulable state and vasculitis in a rat model of sodium laurate-induced thromboangiitis obliterans. Furthermore, the inflammatory molecules COX-2 and ICAM-1 may participate in this effect. In the present study, the effects of Ucn1 on COX-2 and ICAM-1 expression in(More)
Urocortin (UCN) and corticotropin-releasing factor (CRF) are members of CRF family. Though CRF is mainly distributed in central nervous system (CNS), UCN has been reported to play biologically diverse roles in several systems such as cardiovascular, respiratory, digestive, reproductive, stress, immunologic system, etc. UCN and CRF bind to two known(More)
The corticotropin-releasing factor (CRF) family of neuropeptides is composed of CRF, urocortin 1 (UCN 1), UCN 2 and UCN 3, which can bind to CRF-binding protein (CRF-BP) and two known receptors, CRFR1 and CRFR2, to perform many pathophysiological functions, including inflammation. In contrast to its anti-inflammatory effect in the central nervous system,(More)
The small hydrophobic (SH) protein is encoded by the human respiratory syncytial virus. Its absence leads to viral attenuation in the context of whole organisms, and it prevents apoptosis in infected cells. Herein, we have examined the structure of SH protein in detergent micelles and in lipid bilayers, by solution NMR and attenuated total(More)
Diet can be an important factor that influences risks for cardiovascular disease. Genistein (4',5,7-trihydroxyisoflavone), rich in soy, is one candidate that may benefit the cardiovascular system. Here, we explored the effect of genistein in atherosclerosis (AS) development in an in vivo mouse model. Low-density lipoprotein receptor (LDLR) knockout mice(More)
OBJECTIVE Neuropeptide W (NPW), an endogenous ligand for the G protein-coupled receptor 7 (GPR7), was first found to make important roles in central nerve system. In periphery, NPW was also present and regulated intracellular calcium homeostasis by L-type calcium channels. This study was designed to discover the effects of NPW-GPR7 on the function of CaV1.2(More)
