From: Novel role of PAF1 in attenuating radiosensitivity in cervical cancer by inhibiting IER5 transcription

Fig. 4

Knocking down PAF1 affects radiosensitivity of CC by regulating IER5. a&b qRT-PCR assays of mRNA expression in radiation-exposed and unexposed Siha and Hela cells showing increased expression of IER5 and reduced PAF1 after radiation. β-actin served as expression controls. Data are expressed as the mean (S.D.) (n = 3). c&d Western blotting analysis results showing that based on radiation, knocking down PAF1 promoted the expression of IER5, while knocking down IER5 has no significant effect on PAF1. Fold change of intensity is mentioned in the western blotting bands. GAPDH served as expression controls. e&f FCM assay for analyzing the percentage of cells with active caspase-3 showing that PAF1 knockdown resulted in an increased percentage of cell with active caspase-3 and simultaneous PAF1 and IER5 knockdown resulted in little effect on the apoptosis proportion. N = 3 in each group. All data are expressed as the mean (S.D.): * P < 0.05 and ** P < 0.01
