WebMay 20, 2024 · Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown or storage of fats for energy and the synthesis of structural and functional lipids. These fats are obtained from food or are synthesized by the liver. WebBecause ceramide is a second messenger in chemotherapy-induced apoptosis, knowledge of the lipid pathways influenced by PSC 833 is of relevance. In intact MDA-MB 468 breast cancer cells, ceramide generation increased 3-fold 1 h after PSC 833 addition (5.0 microM). Cyclosporine A, a structural analogue, failed to impact ceramide metabolism.
WebLipids are fats that are either absorbed from food or synthesized by the liver. Triglycerides (TGs) and cholesterol contribute most to disease, although all lipids are physiologically important. Cholesterol is a ubiquitous constituent of cell membranes, steroids, bile acids, and signaling molecules.
