Effect of shRNA on expression of c-Myc and hTERT gene in Colo 320 cells. A. c-Myc and hTERT mRNA expression of Colo 320 cells was detected by RT-PCR with different treatments. The cells were subjected to no treatment (control), pGenesil-vector group, 5, 7.5, 10, 12.5 μM shRNA for 48 h. B. c-Myc protein and hTERT expression of Colo 320 cells was detected by Western blotting with different treatments. Typical Western blot results for c-Myc and hTERT protein. Protein expression of c-Myc in Colo 320 cells was quantified by densitometric analysis. All data were obtained from three independent experiments. Error bars represent means ± SEM. Significantly different from the corresponding control (**P < 0.01, vs control. ##P < 0.01, vs vector).
