Fig. 4. Kruppel-Like Factor 4 (KLF4) and Specificity protein-1 (SP1) contribute to IPO13 dependent oxidative stress induced cell death.

IPO13+/+ ESCs were treated without or with siRNAs targeting SP1 or KLF4. 3 d post transfection, cells were treated with H2O2 as indicated for 1 h, and then stained either immediately (“No recovery”) or subsequent to 2 h recovery as indicated, for propidium iodide (PI) and flow cytometric analysis. a Representative dot plots of the indicated samples with the percentage of ESC PI positive. b Pooled data (IPO13+/+ 125 μM (n = 7), IPO13+/+ 300–600 μM (n = 9), IPO13−/− 125–600 μM (n = 9), IPO13+/+ +KLF4 siRNA 125–600 μM (n = 7), IPO13+/+ + SP1 siRNA 125–600 μM (n = 7)) for % PI positive cells relative to untreated (UT) control from the analysis such as that in a are shown (mean ± SEM), where p values (two tailed student’s t test) top to bottom left to right are no recovery: p = 0.6160, p = 0.0032, p = 0.0210, p = 0.0215, p = 0.0198, p = 0.0029, p = 0.0048, p = 0.0326, p = 0.0074, and 2 h recovery: p = 0.6160, p = 0.3882, p = 0.0273, p = 0.6300, p = 0.6484, p = 0.0123, p = 0.1919, p = 0.3598, p = 0.0278.
