Changes in cell apoptosis capacity after RNA interference.

<p>Cell apoptosis in each group were detected using an RNA interference technique and AV/PI staining. A-D: Flow cytometric diagrams; A: un-transfected group, B: NC group (controls transfected by 1 irrelevant interference sequence), C: Gab1 siRNA group, D: VEGFR-2 siRNA group. E: Statistical results of three experiments. The proportion of apoptotic ICBD-1 cells increased in the early stage after Gab1 siRNA or VEGFR-2 siRNA interference compared with NC group, **<i>P</i><0.01. Compared with the un-transfected group, there were no significant changes in early cell apoptosis in the NC group.
