左归丸对MSG-肝再生-大鼠再生肝组织基因表达谱的影响

目的:研究左归丸对MSG-肝再生-大鼠再生肝组织基因表达谱的影响。方法:复制MSG-肝再生-大鼠模型,治疗组给予左归丸5g/kg灌胃,于术后5天处死动物,取再生肝组织液氮冻存。选用1176条与细胞分化增殖相关的基因表达谱芯片,观察再生肝组织基因表达谱的变化。结果:治疗组相对于模型组的差异表达基因有292条(上调表达20条,下调表达272条)。结论:左归丸对MSG-肝再生-大鼠再生肝组织的基因表达谱有显著影响,以基因表达下调为主,提示左归丸通过调控MSG-肝再生-大鼠基因表达而影响其肝再生,下调MSG-肝再生-大鼠再生肝组织基因表达可能是左归丸滋养肝肾的重要分子机制之一。

Effects of Zuogui Pill on Gene Expression Profile of Regenerate Hepatic Tissue in MSG-Liver Regeneration-Rat

Objective: To research the effects of Zuogui Pill on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat.Methods: MSG-liver regeneration-rat models were copied;therapy group were given Zuogui Pill(5g/kg) by intragastric administration.Rats were executed at the 5th day after operation,and the regenerate liver tissues were frozen by liquid nitrogen.1176 gene chips of gene expression profile correlated to cell differentiation and multiplication were adopted to observe the changes of gene expression profile in the regenerate liver tissues.Results: There were 292 differential expression genes in therapy group compared with model group(20 genes were up-regulation expressed and 272 genes were down regulation expressed).Conclusion: Zuogui Pill has significant effects on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat,and most of the genes are down regulation expressed.The result hints that Zuogui Pill could influence the liver regeneration by regulating the gene expressions of MSG-live regeneration-rat.Down regulation of the gene expressions of regenerate hepatic tissue in MSG-liver regeneration-rat possibly is one of the important molecular mechanisms of Zuogui Pill in nourishing liver and kidney.
