摘      要：AIM:During liver regeneration cellular proliferation and apoptosis result in tissue remodeling to restore normal hepatic mass and *** regulators of the apoptotic machinery are the Bcl-2 family proteins but their roles are not well defined throughout the liver *** aimed to analyze the expression levels of bcl-2gene family members during resection induced liver regeneration. METHODS:We performed semi-quantitative RT-PCR to examine the expression level of bak,bax,bcl-2 and bcl-x_L in 70% hepatectomized rat livers during the whole regeneration process and compared to that of the sham and normal groups. RESULTS:The expression of bak and bax was decreased whereas that of bcl-2and bd-X_L was increased in hepatectomized animals compared to normal liver at most time *** also reported for the first time that sham group of animals had statistically significant higher expression of bak and bax than hepatectomized *** addition,the area under the curve (AUC) values of these genes was larger in sham groups than the hepatectomized groups. CONCLUSION:The expression changes of bak,bax,bcl-2 and bcl-X_L genes are altered not only due to regeneration, but also due to effects of surgical operations.
