Sphingolipids play essential roles in various cellular events, including proliferation, differentiation, senescence, apoptosis, and inflammatory responses. Serine palmitoyltransferase (SPT) is the initial and rate-limiting enzyme in the de novo sphingolipid biosynthesis, and thus regulates the level of sphingolipids...

Inhibition of fatty acid synthase (FASN) by the irreversible inhibitor cerulenin leads to cytotoxicity and apoptosis in human cancer cell lines. TOFA is an inhibitor of fatty acid synthesis blocking the synthesis of malonyl-CoA by acetyl-CoA carboxylase (ACC). Both cerulenin (at about 10 µg/ml) and TOFA (at about 1...
