摘要

AIM: To study the effects of losartan and captopril on β-myosin heavy chain (MHC), and α-MHC gene expression. METHODS: Pressure overload was produced by abdominal aortic coarctation (AAC) in rats. α-and β-MHC mRNA were measured by Northern blot. RESULTS: In left ventricular myocardium of sham-operated rata , the α-MHC mRNA predominated, while the β-MHC mRNA was only detectable. In response AAC, there was a 70-fold increase in the β-MHC mRNA (P<0.01), while α-MHC mRNA reduced to 26/100 (P<0.01). Losartan (3 mg·kg~-1·d~-1, ig for 11 d) to AAC rats caused inhibitions of β-MHC by 96/100 and α- MHC by 86/100 gene expression without lowering blood pressure. A reduction in β-MHC mRNA was also seen in captopril-treated rats (30 mg·kg~-1 ·d~-1, ig for 11 d), but the inhibitory effect of captopril on α-MHC mRNA was leas than that of losartan (44/100 vs 86/100, P<0.05).
