Figure 2. Bcl-2 mRNA expression is suppressed by Bcl-2 shRNA. At 48 h after transfection, the relative expression of Bcl-2 mRNA was measured using real-time PCR. The Bcl-2 mRNA expression of the PAMAM group and liposome group were greatly reduced compared with the negative control shRNA group (NC group) and the empty control group (EC group).* p<0.05 is significantly different from the liposome group.
