Cytosolic phospholipase A2 (cPLA2α) catalyzes the hydrolysis of membrane glycerophospholipids to release arachidonic acid, which is converted to bio-active eicosanoid lipid mediators, including prostaglandins (like PGE2) produced through cyclo-oxygenases (COX). The eicosanoid signalling contributes to cell proliferation in breast cancer, as demonstrated by numerous studies outlining a crucial role of COX-2 and PGE2 in breast carcinoma progression. The specific ...
