摘要

将人HSS基因导入BEL-7402肝癌细胞,用Northern和Southern杂交法证实该基因在靶细胞中有稳定表达。并通过测定细胞生长曲线、细胞S期比例和细胞MAPK活性,观察到转HSS基因BEL-7402细胞增殖发生了改变。实验结果提示,HSS表达的肝癌细胞DNA合成增加、增殖速度加快,可能与MAPK激活有关。HSS基因表达可促进细胞增殖。

Abstract

It is concluded that the introduction of HSS gene into hepatoma cells might be able to stimulate directly the cellular growth in vitro, allowing a possibility of revaluation of HSS mechanism in intact cells.

Key words: Hepatic stimulatory substance;Gene transfection;Liver proliferation
