季节变化对CUMS模型动物肝脏BSEP基因mRNA表达的影响OA
Influences of Seasonal Changes on BSEP Gene mRNA Expressions in the Liver of CUMS Animal Models
目的:观察季节变化对慢性轻度不可预见性应激(chronic unpredictable mild stress,CUMS)模型动物肝脏胆酸盐输出泵(bile salt export pump,BSEP)基因mRNA表达的影响.方法:选用健康雄性SD大鼠,分别于春分、夏至、秋分、冬至前1周购入,随机分为正常组与CUMS模型组;采用CUMS法构建肝失疏泄动物模型,通过实时荧光定量TaqMan检测肝脏组织中BSEP基因mRNA表达水平,分析其变化规律.结果:与同一季节正常组比较,CUMS组大鼠肝脏BSEP基因mRNA表达水平均显著增高;秋季各组大鼠肝脏BSEP基因mRNA表达水平均较春季组明显降低.结论:BSEP基因表达存在季节性变化特征,且该变化可能与肝主疏泄功能存在相关性.
Objective:To observe the influences of seasonal changes on bile salt export pump(BSEP)gene mRNA expressions in the liver of CUMS animal models.Methods:Healthy male Sprague-Dawley(SD)rats were purchased one week before the vernal equinox,summer solstice,autumnal equinox,and winter solstice,respectively,and they were randomized into the normal group and CUMS model group.CUMS method was adopted to construct animal models of liver failing to govern free coursing,TaqMan real-time quantitative PCR was applied to detect the levels of BSEP gene mRNA in liver,and to analyze the trends.Results:Compared with the normal group in the same season,CUMS group exhibits the elevated expressions of BSEP gene mRNA in liver;BSEP gene mRNA expressions in liver of the rats from all groups in autumn were lower than these in spring remarkably.Conclusion:The expressions of BSEP gene reveal seasonal changes,and the changes may be related to liver governing free coursing.
