C75, an inhibitor of fatty acid synthase (FAS), induces apoptosis in cultured human cancer cells. Its proposed mechanism of action linked high levels of malonyl-CoA after FAS inhibition to potential downstream effects including inhibition of carnitine palmitoyltransferase-1 (CPT-1) with resultant inhibition of fatty acid oxidation. Recent data has shown(More)
Fatty acid synthase (FAS), the enzyme responsible for the de novo synthesis of fatty acids, is highly expressed in ovarian cancers and most common human carcinomas. Inhibition of FAS and activation of AMP-activated protein kinase (AMPK) have been shown to be cytotoxic to human cancer cells in vitro and in vivo. In this report, we explore the cytotoxic(More)
Inhibition of brain carnitine palmitoyl-transferase-1 (CPT-1) is reported to decrease food intake and body weight in rats. Yet, the fatty acid synthase (FAS) inhibitor and CPT-1 stimulator C75 produces hypophagia and weight loss when given to rodents intracerebroventricularly (icv). Thus roles and relative contributions of altered brain CPT-1 activity and(More)
Markers of early pancreatic cancer and its precursors are needed to improve the uniformly poor prognosis of this disease. Fatty acid synthase (FAS) catalyzes the synthesis of long-chain fatty acids and is overexpressed in most human solid tumors. We therefore evaluated serum FAS as a marker of pancreatic adenocarcinoma. FAS expression patterns in primary(More)
PURPOSE Fatty acid synthase (FAS) is overexpressed in many human cancers and is considered to be a promising target for therapy. However, in vitro use of previous generations of FAS inhibitors has been limited by severe, but reversible, anorexia in treated animals, which is thought to be related to a parallel stimulation of fatty acid oxidation by these(More)
