Abstract:
Objective: To construct eukaryotic expression vector of tumor-associated gene SNC90 and transfect it into human colorectal cancer cell lines. Methods: A 1.5 kb tumor-associate gene SNC90 full length cDNA was inserted into a mammalian expression vector pREP9 to make recombinant vector pREP9-SNC90, which was then introduced into three kinds of colorectal cancer cell lines, SW1116, COL0205 and SW620, by lipofection or electroporation. The cells resistant to G418 drug were selected. Results: Cells transfected with pREP9-SNC90 showed fewer G418-resistant colonies than those transfected with void vector, the inhibitory rates are 72.2%, 74.2% and 59.7%, respectively. Conclusion : SNC90 may play a negative role in regulating growth of colorectal cancer cell.
