SGK1 regulates p27 mRNA and protein levels. (a) p27 mRNA levels in HCT116 cells treated with SGK1 overexpression plasmids or the SGK1 inhibitor GSK650394. (b) p27 and SGK1 protein expression levels. (c–e) HCT116 cells treated with GSK650394 (10 μM), MG132 (10 μM) or GSK650394 (10 μM)+MG132 (10 μM) for 24 h were subjected to western blot analysis to detect p27 in total cell lysates (c), the cytoplasmic fraction (d) and the nuclear fraction (e). *, 0.01<P<0.05; **, 0.001<P<0.01; ***P<0.001.
