Silencing of Bcl-2 in HeLa and CaSki cells and resulting expression levels of Beclin-1. a Silencing of Bcl-2 confirmed through Western blotting. Beclin-1 protein expression in HeLa cells, *p < 0.05, **p < 0.01, ***p < 0.001, n = 3. b Silencing of Bcl-2 confirmed through Western blotting. Beclin-1 protein expression in CaSki cells, *p < 0.05 vs. cisplatin, n = 3. c Ratios were determined according to densitometric analysis of Beclin-1 and Bcl-2. *p < 0.05 and **p < 0.01, n = 3. Sc. Seq. scrambled sequence (control), AU arbitrary units
