PC3, DU145, and LNCaP cells were pre-treated with AICAR (1 mM) or compound C (5 μM) for 1 h. The cells were then either left untreated or were treated with Orlistat (100 μM) for 24 h. Cell lysates were collected and analyzed for FASN, mature SREBP-1c, pACC, and pAMPK protein expression by Western blotting. Blots were stripped and reprobed for ACC, AMPK, and β-actin protein expression as a loading control. Representative blots from three or more independent experiments are shown.
