ANRIL knockdown overcomes MK-induced cisplatin resistance via activation of caspase-3-dependent apoptosis. The effect of MK on the cell viability of cisplatin-treated HSC3 (a), OSCC3 (b) and SCC4 (c) cells transfected with either si-NC or si-ANRIL was determined by CCK-8 assays. Values represent the mean ± SD from three independent experiments (*P < 0.05, **P < 0.01, ***P < 0.001). The expression of PARP, Bcl-2, cleaved caspase-3 and caspase-3 in siNC- or si-ARNIL-transfected HSC3 (d), OSCC3 (e) and SCC4 (f) cell lines with either treatment of exogenous MK (100 ng/ml) or without MK was analysed by western blot. A representative experiment of four is shown. (g) A suggested mechanism for the CAF-derived MK-mediated enhancement of tumour cell resistance to cisplatin.
