Cell cycle block in PHD3 depleted cells is p27-dependent. a Reduced cell proliferation as judged by reduced cell amount of hypoxic siPHD3-depleted HeLa cells is rescued with concomitant p27 knockdown. b Quantification of cell survival from four independent experiments with 4–5 optical views per experiment. Asterisk indicates significant difference (p = 0,05; n = 4). Protein expression was monitored with western blotting from parallel samples. c Knockdown of p27 restores the effect of PHD3 depletion on cell cycle. HeLa cells exposed to the indicated double knockdown followed by 6 h hypoxia and FACS analysis. d Quantification of cell cycle phases from three independent experiments using indicated double knockdown
