Analysis of Beclin-1 and Bcl-2 protein levels in non- treated (NT) and treated (T) HeLa and CaSki cells. a Bcl-2 and Beclin-1 protein levels in HeLa and CaSki cells were analysed for changes in expression after the addition of 15 μM cisplatin for a period of 24 h. *p < 0.05, **p < 0.01, ***p < 0.001, n = 3. Analyzed by one-way ANOVA with Bonferonni post hoc test. b Representative immunofluorescent images of HeLa and CaSki cells depicting expression of Bcl-2 and Beclin-1 under basal conditions (NT) and in response to cisplatin treatment (T). Blue Hoechst 33342, green Bcl-2 and red Beclin-1. Scale bar 20 μm, n = 3
