Fig. 4From: Ribonucleic acid interference knockdown of IL-6 enhances the efficacy of cisplatin in laryngeal cancer stem cells by down-regulating the IL-6/STAT3/HIF1 pathwayProliferation results after siRNA-IL-6 knock down. Cisplatin or siRNA-IL-6 significantly inhibited Hep2-CSC cell proliferation in a temporally-dependent manner. The combined treatment of cisplatin and siRNA-IL-6 significantly enhanced the inhibitory effect of siRNA-IL-6. *p < 0.05, **p < 0.01 vs hep2-CSC controlBack to article page
