大鼠部分肝切除前后热激处理对过氧化物酶基因表达的影响 Expression Difference of the Peroxidase Genes in Partial Hepatectomy and Heat Shock

用过氧化物酶原位复性电泳(SDS-POD-PAGE)技术分析了部分肝切除(partial hepatectomy,PH)、部分肝切除后再热激(partial hepatectomyfollowing heat shock,PH-HS)和先热激再部分肝切除(heat shock follow ing partial hepatectomy,HS-PH)后肝再生期间过氧化物酶(POD)基因表达差异,结果表明,PH中表达的POD基因种类(7个)>PH-HS(5个)>HS-PH(3个);三个模型的POD总活性为:HS-PH>PH>PH-HS.根据实验结果推测,POD在肝再生和肝损伤恢复中起一定作用。 Abstract:Expression difference of the peroxidase(POD)genes during liver regeneration after partial hepatectomy(PH),partial hepatectomy following heat shock(PH-HS)and heat shock following partial hepatectomy(HS-PH)was analyzed by POD renatured electrophoresis(SDS-POD-PAGE).The results showed that the expressed POD gene kinds in PH,PH-HS and HS-PH were 7,5 and 3 respectively,and that the total activities of POD in the three models were HS-PH>PH>PH-HS.The results suggested that POD play some roles during liver regeneration and in recovery after liver damage.
