    • 摘要: 肾间质纤维化是慢性肾脏病发生发展过程中的重要病理特征之一。在肾损伤的过程中,分布于肾脏细胞内的肝再生增强因子表达上调,通过免疫调控、提高氧化酸化能力和巯基氧化酶等作用参与肾损伤调控。肝再生增强因子可从抗肾小管细胞凋亡、抑制转化生长因子β信号通路、抑制细胞外基质合成、刺激细胞外基质降解、阻断信号通路及抑制炎症反应等多个方面干预肾间质纤维化的发生发展,保护肾脏功能。肝再生增强因子有望成为预防和减轻肾间质纤维化损伤的作用靶点。

Methods HepG2 cells transferred with expression vector pcDNA3.1(-)hALR were screened by G418. After in vitro culture and subculture, the expression of hALR were detected by Western blot and immunolfuorescence assay in two HepG2 cell lines transferred with or without expression vector. The secretion of hALR in the culture lfuid of the two HepG2 cell lines were detected by ELISA. Ki-67 in two HepG2 cell lines were detected by lfow cytometry to understand the proliferation of HepG2 cells transferred with or without expression vector. Results The function of HepG2 cell line transferred with expression vector pcDNA3.1(-)hALR was stable. HepG2 cells transferred with expression vector pcDNA3.1(-) hALR expressed and secreted more hALR than HepG2 cells, and with the extension of culture time, the content of hALR in the culture lfuid of HepG2 cells transferred with expression vector pcDNA3.1(-)hALR increased more rapidly than those of HepG2 cells. The Ki-67 positive cells in HepG2 cells transferred with expression vector pcDNA3.1(-)hALR were signiifcantly more than those of HepG2 cells, which indicated that the proliferation of HepG2 cells became more active by transfection of expression vector pcDNA3.1(-)hALR.

    • 摘要: 目的 研究肝再生增强因子(ALR)保护急性肝损伤的作用及其机制. 方法 HL-7702细胞分为正常对照组、CCl4急性肝损伤组、ALR+CCl4干预组、3-甲基腺嘌呤(3-MA) +CCl4干预组以及ALR+3-MA+CCl4干预组,CCl4处理前8h对ALR+CCl4和ALR+3-MA+CCl4干预组转染ALR质粒,对除正常对照组外其余四组给予CCl4处理,30 rain后对3-MA+CCl4和ALR+3-MA+CCl4干预组给予3-MA处理,CCl4处理24 h后收集细胞.收集HL-7702细胞和培养上清液,检测丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)水平;Western blot检测细胞中ALR、细胞周期蛋白D、细胞周期蛋白E、增殖细胞核抗原(PCNA).自噬相关基因7(Atg7)和自噬基因LC3、p62、Beclin-1水平;实时定量PCR检测ALR mRNA水平.多组样本均数的两两比较采用One-way ANOVA分析. 结果 ALR+CCl4干预组与急性肝损伤组相比,ALR蛋白以及mRNA表达水平显著升高(P值均< 0.05);CCl4急性肝损伤组与正常对照组相比,ALR蛋白以及mRNA表达水平同样显著升高(P值均< 0.05).ALR+CCl4干预组与CCl4急性肝损伤组相比,细胞上清液中ALT (0.73±0.17与1.43±0.38,P值均<0.05)、AST(19.85±1.83与56.73±6.25,P值均<0.05)水平显著降低(单位均为IU/L);肝细胞中再生相关细胞周期蛋白D、细胞周期蛋白E、PCNA表达水平以及自噬相关LC3、Atg7.Beclin-1表达水平显著增高,P62表达水平显著降低,提示ALR可以保护急性肝损伤,促进肝细胞的再生,增强肝细胞的自噬水平.ALR+3-MA+CCl4干预组再生相关蛋白的表达水平相较于ALR+CCl4干预组明显降低,与3-MA+CC14干预组相比无明显差异,提示抑制自噬后,肝细胞再生水平明显下降,ALR促进肝再生的作用也明显减弱.结论 ALR可以促进肝脏实质细胞再生,这种再生是通过调节自噬完成的.%Objective To investigate the protective effect of augmenter of liver regeneration (ALR) against acute liver injury and related mechanisms.Methods HL-7702 cells were divided into normal control group,carbon tetrachloride (CCl4)-induced acute liver injury group,ALR+CCl4 intervention group,3-methyladerine (3-MA)+CCl4 intervention group,and ALR+3-MA+CCl4 intervention group.The ALR+CCl4 and ALR+3-MA+CCl4 intervention groups were transfected with ALR plasmids at 8 hours before CCl4 treatment.All groups except the normal control group were treated with CC14,and 30 minutes later,the 3-MA+CC14 and ALR+3-MA+CCl4 intervention groups were treated with 3-MA.The cells were collected at 24 hours after CCl4 treatment.The HL-7702 cells and supematant were collected to measure the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (IU/L).Westem blot was used to measure the levels ofALR,cyclin D,cyclin E,proliferating cell nuclear antigen (PCNA),autophagy-related gene 7 (Atg7),and autophagy genes LC3,p62,and Beclin-1.Quantitative real-time PCR was used to measure the mRNA expression ofALR.A oneway analysis of variance was used for comparison of means between any two groups.Results The ALR+CCl4 intervention group had significant increases in the protein and mRNA expression of ALR compared with the acute liver injury group (both P < 0.05).The CC14-induced acute liver injury group had significant increases in the protein and mRNA expression of ALR compared with the normal control group (both P < 0.05).Compared with the CCl4-induced acute liver injury group,the ALR+CCl4 intervention group had significant reductions in ALT (0.73±0.17 IU/L vs 1.43±0.38 IU/L,P < 0.05) and AST (19.85±1.83 IU/L vs 56.73±6.25 IU/L,P < 0.05) in supematant,significantly increased expression of cyclin D,cyclin E,PCNA,LC3,Atg7,and Beclin-1 in hepatocytes,and significantly reduced expression of p62,which suggested that ALR protected the liver against acute liver injury,promoted the regeneration of hepatocytes,and enhanced the autophagy of hepatocytes.The ALR+3-MA+CCl4 intervention group had a significant reduction in the expression of regeneration-associated proteins compared with the ALR+CCl4 intervention group,while there was no significant difference between the ALR+3-MA+CCL4 intervention group and 3-MA+CCL4 intervention group,which suggested that after the inhibition of autophagy,there were significant reductions in the regeneration of hepatocytes and liver regeneration promoted by ALR.Conclusion ALR can promote the regeneration of hepatocytes in liver parenchyma,which is achieved by the regulation of autophagy.
