| 摘 要： | Protein kinase C (PKC), which has a wide variety of functions, comprises at least twelve isoenzymes that have distinct roles respectively. Research in recent years indicates that PKCζ plays a pivotal role in the regulation of cell proliferation. In order to investigate its role in the regulation of keratinocyte proliferation, eukaryotic expression plasmid of anti_sense PKCζ is constructed and transfected into human keratinocyte line, Colo16. The human keratinocyte model expressing anti_sense PKCζ is established successfully, the growth properties of the cell model is analyzed by the detection of cell growth curve and cell cycle phase. The mechanism of the relationship between PKCζ and CyclinD1 is also investigated by the western blotting analysis of CyclinD1 protein.
