Figure 5.
FASN inhibition is associated with a drop in ChoK activity (A) but not in long term inhibition of PI3K singling (B). A. 1H MR spectrum of cell lysates showing endogenous PCho and added Cho. Inset: representative plot of PCho synthesized by ChoK extracted from control cells and 48 h Orlistat-treated cells. Lines represent the straight-line fits to the data used to obtain rates of PCho synthesis (R2 = 0.89, Control; R2 = 0.96, Orlistat) indicating inhibition of ChoK following Orlistat treatment. B. Western blot analysis of P-Akt, Akt and GAPDH (loading control) expression in control and treated PC-3 cells following 3, 24 and 48 hours of Orlistat treatment.
