Researchers describe the role of the arachidonate cascade during changes in the life cycle of adipocytes in a recent issue of Applied Biochemistry and Biotechnology.

According to a study from Japan, "Although some eicosanoids serve as potent natural ligands to activate peroxisome proliferator-activated receptor (PPAR-gamma), the ability of adipocytes to produce eicosanoids and regulate PPAR-gamma remains unclear. Here, adipogenic 3T3-L1 cells were employed to determine the gene expression of isoforms of biosynthetic enzymes in the arachidonate cyclooxygenase (COX) pathway and the synthesis of prostaglandins (PGs). The expression of COX-2 was induced transiently...
