(A–H) A549 (A, B, E, and H) or H1299 (C, D, F, and G) cells were transfected with the indicated plasmids or siRNAs. Forty-eight h later, a portion of cells were harvested for RT-PCR or IB analysis (A, C, and F). Another portion was grown for 48 h, cell numbers (left: B, D, and G) were counted, and percentage of apoptotic cells (E and H) were measured. Still other portions were plated into 6-well plates, and colonies with more than 50 cells counted after 9–13 days (right: B, D, and G). The error bars represent SEM from three independent experiments; *p < 0.05, **p < 0.01, and ***p < 0.001.
(I–L) H1299 (I–L) or A549 (I, right) cells were transfected with indicated plasmids or siRNAs and harvested 48 h later for IB (I and J) or counting cell numbers (K) and colonies (L). The error bars represent SEM from three independent experiments; *p < 0.05, **p < 0.01, and ***p < 0.001.
