ABSTRACT

Objective To observe the effects of ACE inhibitor enalaprilat(Ena) and protein kinase C(PKC) inhibitor chelerythrine(Chele)on proliferation,collagen Ⅰ,cell cycle,PKC and cyclinD1 protein expression of neonatal cardiac fibroblasts(CFb) and to probe its molecular mechanism.Methods CFb of neonatal Wistar rats were divided into control group,AngⅡ group,Chele+AngⅡ group,Chele+AngⅡ+Ena group and AngⅡ+Ena group.CFb were isolated by trypsin digestion method.MTT colorimetric assay was adopted to evaluate cell proliferation,immunocytochemical staining(IC) was used to measure collagen Ⅰ content,Western blotting and flow cytometry were used to detect PKC,cyclinD1 and cell cycle respectively.Results Compared with AngⅡ group,the MTT value decreased dramatically(P
