ETS1 and FLI1 cooperate in sustaining cell viability in OCI-Ly7. (A) ETS1 and FLI1 concomitant down-regulation in OCI-Ly7 cell line. Real-time PCR (left) and western blot (right) analysis of ETS1 and FLI1 levels after shRNA (day 4) after infection. (B) ETS1 and FLI1 down-regulation induce apoptosis in a cooperative manner. Dot plots are representative of 1 experiment; histogram graphs represent the average of 3 independent experiments. **P value < .05.
