Effects of resveratrol were diminished in PC3 cells expressing a stable HIF-1α mutant. (A) HIF-1α in cells expressing wt or mutant HIF-1α in normoxic conditions. (B) Cellular respiration rates and (C) mitochondrial network characteristics in cells expressing mutant HIF-1α and treated with either 10 µM RES or vehicle control (DMSO) for 48 h. (D) Population doubling time and (E) cell cycle distribution for cells expressing mutant HIF-1α. In (B-E) open bars are DMSO vehicle control and filled bars are 10 µM RES. Data shown are means ± SEM of (A) 4; (B) 5–6; (C) 44; (D) 9 and (E) 6 independent measurements. *P<0.05 RES-treated vs. DMSO-treated cells; ‡P<0.05 wtHIF-1α vs. mutHIF-1α.
