Effect of cholbut SLN on Akt phosphorylation in HCT15 (A), HCT116 (B), HT29 (C) and PC-3 (D). Cells were treated with 100 μM cholbut SLN for 8, 24 or 48 h and subsequently incubated with fresh media containing (0.01 μM) PMA to induce Akt phosphorylation, which was then evaluated by Western blot in the cell lysates. The same blots were probed with anti β-actin antibody as a control. Left: Western blot analysis from a representative experiment. Right: Densitometric analysis of Akt phosphorylation expressed in arbitrary units;data are expressed as means ± SEM (n = 3) and shown as % control. *P < 0.05; **P < 0.01, significantly different from PMA alone; one-way ANOVA and Dunnett's test.
