Abstract:
Objective To investigate the effect of a new cloned full length gene, C2 gene which encodes a translation initiation factor, on cell cycle and the relationship between C2gene and apoptosis. Methods Construct a eukaryotic vector carrying the full length of C2 gene, then transfected it into a gastric cell line-SGC7901 cells and gained cells expressing C2 protein transiently or stably. Test the expression of C2 protein and the change of cell cycle of the transfected cells using the flurescence activatied cell sorting(FACS) and the changes of their ultra structure electromicroscopically. Results The C2 gene eukaryotic expression vector was successfully constructed. FACS showed the C2 protein expression ratio of transfected cells was 32.3%, while the empty control group was 0.9%. The test of cell cycle showed that there was appeared apoptosis peak in transiently or stably transfected cells. The apoptosis cells can be seen electromicroscopically among the C2 transfected cells. Conclusions C2 gene transfection can lead SGC7901 cells to apoptosis, but the mechanism has to be further study.
