Survivin is essential for the salinomycin-induced apoptosis in UM cells. a UM cells were treated with salinomycin for 24 h and the protein levels of apoptosis-related proteins were detected by Western blot. b and c UM cells were transduced with lentiviral pTSB-Survivin cDNA (b), Survivin-shRNA constructs (c), or their corresponding empty vectors, and then incubated in the presence of puromycin (1 μg/mL) for 5 days to reach stable clones. Such survivin-manipulated cells were then exposed to salinomycin for 24 h, and subjected to trypan blue exclusion assay (left) and Western blot assay (right). Data represent mean ± SD. ns, not significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001, Student’s t test. d qRT-PCR analysis of BIRC5 mRNA level was done in the 92.1 and Mel270 cells treated with salinomycin for 24 h. **, P < 0.01; ***, P < 0.001, one-way ANOVA, post hoc comparisons, Tukey’s test
