Abstract:
:This study aimed to search genes altered in expression after long-term treatment with the angiotensin II type 1 receptor (AT1) antagonist, CV-11974, in volume-overloaded hearts. Arteriovenous shunt was made between the common carotid artery and jugular vein in Japanese White rabbits. Shunt-operated rabbits were randomly treated with CV-11974 or vehicle for 6 weeks, starting 6 weeks after surgery. As controls, sham-operated rabbits were given vehicle. Total RNA was prepared from each left ventricular myocardium. Using differential display, we screened one cDNA encoding human beta-catenin, in which the expression was upregulated after CV-11974 administration in shunt rabbit hearts. Beta-catenin is a molecule that exists in the intercalated disks and also works in cytoplasm as a major component of Wnt signaling. We then examined mRNA expressions of beta-catenin and connexin43 by semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR). The mRNA expressions of beta-catenin and connexin43 were markedly depressed in shunt-operated animals given vehicle compared with sham-operated animals (P < 0.01). These results suggest that downregulation of beta-catenin and connexin43 expression might be involved in the process of ventricular remodeling by volume overload. The RT-PCR also demonstrated that beta-catenin mRNA expression was significantly higher in shunt rabbits treated with CV-11974 than in those given vehicle (P < 0.05). These data suggest that volume overload may downregulate beta-catenin expression by an AT1 receptor-mediated pathway.
