Potential role of acid ceramidase in conversion of cytostatic to cytotoxic end-point in pancreatic cancer cells.
PURPOSE Acid ceramidase (AC) occupies an important place in the control of cancer cell proliferation. We tested the influence of AC inhibition on the effects of PSC 833, a P-glycoprotein antagonist with potent ceramide-generating capacity, to determine whether AC could be a therapeutic target in pancreatic cancer. METHODS Ceramide metabolism was followed using 3H-palmitate, and molecular species were determined by ... Read more
