摘要
The expression of immediate early gene plays a pivotal role in rat hepatocyte proliferation from G0 to G1 phases and the progression through G1 phase of the cell cycle within several hours after 2/3 hepatectomy. We investigated the different gene expressions within 1 h after 2/3 hepatectomy by representational difference analysis. Sequence analysis indicated that PC3 induced by NGF was a kind of immediate early gene and might be correlated with liver regeneration. Moreover, we found that 2/3 hepatectomy could induce the expressing of PC3 mRN A by Northern blot with a peak 1-2 h after surgery. In primary cultures of rat hepatocytes, addition of EGF resulted in rapid and transient induction of PC3 mRNA. It was first reported that PC3 gene belongs to immediate early gene associated with liver regeneration.
