Abstract
Objective To investigate effect of let-7a gene over-expression on apoptosis of gastric cancer cell lines SGC-7901.Methods The stable let-7a gene over-expressing SGC-7901 cells, SGC-7901/let-7a cells, were established using shRNA lentiviral vector methods. Real-time RT-PCR analysis was used to evaluate the expression level of let-7a mRNA. Cells apoptosis was assessed by flow cytometry.Results RT-PCR analysis revealed let-7a expression in SGC-7901/let-7a cells was significantly increased. Cellular apoptosis assay showed that over-expression of let-7a could increase apoptosis of SGC-7901 cells (P=0.002).Conclusion Up-regulating let-7a expression promoted apoptosis in SGC-7901 cells.
