Semiquantitative RT-PCR analysis of apoptosis regulators. (A) Graphic analysis of semiquantitative RT-PCR for Bcl2, Bcl7C, and Bax RNA levels after 48 hr of treatment with either 2 µM IL-10 RNAi (hatched bars) or 2 µM dsScr (gray bars) when compared to an untreated control. Numbers represent percent of control values from triplicate gels. Error bars are SEM. Asterisks indicate P < 0.05 for a Students t-test comparing dsScr to RNAi. (B) Representative PCR gels stained with ethidium bromide. Lane 1 is control, lane 2 is 2 µM dsScr and lane 3 is 2 µM IL-10 RNAi.
