Knockdown of glycolytic genes or HIF1α reduced SRC-3 overexpression accelerated bladder cancer cell proliferation.
A, efficiency of RNA interference targeting HK-2 (siHK-2) and LDHA (siLDHA) in SRC-3 overexpressed (#1) and control cells determined by Western blot analysis. B–E, cell proliferation in SRC-3 overexpressed and control cells with the treatment of siHK-2 (B), siLDHA (C), 2-DG (12.5 mg/ml) (D), and sodium oxamate (80 mm) (E). F, efficiency of RNA interference-targeting HIF1α (siHIF1α) in SRC-3 overexpressed (#1) and control cells determined by Western blot analysis. G, cell proliferation in SRC-3 overexpressed (#1) and control (CTRL) cells with treatment of siHIF1α were detected by MTT assay. *, p < 0.05; **, p < 0.01; ***, p < 0.001.
