摘要: 试验将F81猫肾细胞随机分为对照组、药物组(猫细小病毒(FPV)+利巴韦林)、病毒组(FPV感染),采用实时荧光定量PCR的方法,检测Bcl-2、Bcl-xl、Bax和Caspase 3等凋亡相关基因的相对表达量。结果显示,与对照组相比,病毒组细胞凋亡增加,抗凋亡基因Bcl-2 mRNA表达受到抑制,Bax mRNA和 Caspase 3 mRNA的相对表达量均有不同程度的上调。药物组细胞的抗凋亡基因Bcl-2和Bcl-xl的表达水平显著高于病毒组(P<0.05),且总体呈上调状态,但72 h时Bcl-xl表达量减少;而药物组的促凋亡基因BaxCaspase 3的表达量显著低于病毒组(P<0.05),48 h前,Bax 的表达量呈递减状态,72 h时检测结果显示药物组Bax表达量相比对照组显著上调(P<0.05),但仍显著低于病毒组(P<0.05);与对照组相比,病毒组和药物组Caspase 3的表达量在72 h时显著上调(P<0.05)。综上所述,利巴韦林可在基因水平通过上调抗凋亡基因Bcl-2和Bcl-xl和下调促凋亡基因BaxCaspase 3的表达来抑制FPV感染诱导的F81猫肾细胞凋亡发生。

Abstract: The F81 cells were divided into three groups,control group,feline panleukopenia virus (FPV) infected group and ribavirin treatment group,we used Real-time fluorescent quanlitative PCR to detect the expression of Bcl-2,Bcl-xl,Bax and Caspase 3.Real-time fluorescent quanlitative PCR results showed that the number of apoptotic cells increased in FPV infected group compared with the control group,and mRNA levels of Bcl-2 was inhibited,which was an anti-apoptotic gene,while the expressions of Bax and Caspase 3 were both increased.In ribavirin treatment group,expression levels of Bcl-2 and Bcl-xl were significantly higher than that of FPV infected group (P<0.05),and had a peak at 48 h in all time points.However,mRNA levels of Bax and Caspase 3 in ribavirin treatment group were significantly lower than that of FPV infected group (P<0.05),and the lowest levels were at 72 h in all time points.In a word,ribavirin could inhibit the apoptosis of F81 cells infected by FPV at the genetic level.

Key words: ribavirin; F81 cells; gene expression; cell apoptosis
