ABSTRACT
Objective:
To investigate the effects of calcineurin signaling pathway on the collagen synthesis of rat cardiac fibroblasts(CF) induced by arginine vasopressin(AVP).Methods:
CF of neonatal Sprague-Dawley rats were secured by trypsinization and Cultured.Collagen content of CF culture medium was estimated by hydroxyproline colorimetry.Calcineurin activity was determined with spectrophotometer.Results:
① AVP increased the content of hydroxyproline in culture medium of CF in a concentration dependent manner.But in the presence of 0.5 ?g/ml cyclosporin A(CsA),the specific inhibitor of calcineurin,the hydroxyproline content of culture medium in corresponding AVP+CsA group was significantly lower than that of 10~(-7) mol/L AVP or 10~(-6)mol/L AVP group(both P
