Research Abstract |
We investigated a mechanism why hepatocytes express Heregulin(HRG) in the situation of hepatic metastasis of colorectal cancer. Immunohistochemical(IHC) examination on human specimen of hepatic metastasis revealed that HRG was expressed in hepatocytes at 88.7 %. The expression was evident in hepatocytes which were close to the metastatic tumor but not in those which were contact to the tumor with being injured nor in far region. Dimethylnitrosoamine(DMN) caused significantly increased expression of HRG mRNA in rat hepatocytes from day 1 compared with that of the control. IHC examination revealed that HRG expression in hepatocytes started from day 1 around the area of Glisson's capsule but not in the area of central zone of hepatic lobules where were injured by DMN. Partial hepatectomy also revealed that hepatocytes in the residual liver expressed HRG. These results suggest that HRG expression is appeared in the residual hepatocytes in the stage of injury and regeneration of the liver.
