Suppression of NDRG2 inhibited Bcl-2 expression in Hela cells. A. The expression of Bcl-2, Bax, P-glycoprotein (P-gp) and multidrug resistance protein (MRP) in Hela and its stable variants was evaluated by Western blot with β-actin as loading control. Shown are representative of 3 independent experiments. B. Densitometric analysis of Western blot assay was further performed. Data was expressed as fold change using Hela cells as reference. * p < 0.01 vs Hela and scramble control. Δ p < 0.01 vs Hela. # p > 0.05 vs scramble control.
