Response of OLFM4 knockdown SGC-7901 and MKN45 cells to apoptosis-inducing agents H 2 O 2 or TNF α. OLFM4 knockdown and HK control cells were treated with H2O2 (A and B) or TNF α (C and D) as indicated doses for 12 h. Cell viability was measured by WST-1 assay (A-D left panels) and expressed in the mean OD value (450 nm) (n = 3). The percentage of the apoptotic cells was determined by FCM (A-D right panels) and expressed in the mean apoptotic percentage (n = 3). *P < 0.05,**P < 0.01 vs. HK control group.
