Role of the Phospholipase A2 Receptor in Liposome Drug Delivery in Prostate Cancer Cells
The M-type phospholipase A2 receptor (PLA2R1) is a member of the C-type lectin superfamily and can internalize secreted phospholipase A2 (sPLA2) via endocytosis in non-cancer cells. sPLA2 itself was recently shown to be overexpressed in prostate tumors and to be a possible mediator of metastasis; however, little is known about the expression of PLA2R1 or its function in prostate cancers. Thus, ...
متن کاملInvolvement of epigenetic mechanisms in the regulation of secreted phospholipase A2 expressions in Jurkat leukemia cells.
Epigenetic changes provide a frequent mechanism for transcriptional silencing of genes in cancer cells. We previously established that epigenetic mechanisms are important for control of group IIA phospholipase A(2) (PLA2G2A) gene transcription in human DU-145 prostate cells. In this study, we analyzed the involvement of such mechanisms in the regulation of five sPLA(2) isozymes and the M-type r...
متن کاملSecretory phospholipase A2 receptor-mediated activation of cytosolic phospholipase A2 in murine bone marrow-derived mast cells.
The current study examined the signal transduction steps involved in the selective release of arachidonic acid (AA) induced by the addition of secretory phospholipase A2 (sPLA2) isotypes to bone marrow-derived mast cells (BMMC). Overexpression of sPLA2 receptors caused a marked increase in AA and PGD2 release after stimulation of BMMC, implicating sPLA2 receptors in this process. The hypothesis...
متن کاملAnti-phospholipase A2 Receptor Antibody and Immunosuppression in Membranous Nephropathy: More Evidence for Pathogenicity of Anti-phospholipase A2 Receptor Autoantibodies.
In the 6 years since the discovery of anti-phospholipase A2 receptor (anti-PLA2R) antibodies in the majority of patients with primary membranous nephropathy (MN),1 our understanding of the role of anti-PLA2R in clinical disease has evolved rapidly. The initial small retrospective clinical studies indicated that anti-PLA2R levels could be modulated by immunosuppression.1,2 Levels decreased in ad...
متن کاملLipoquality control by phospholipase A2 enzymes
The phospholipase A2 (PLA2) family comprises a group of lipolytic enzymes that typically hydrolyze the sn-2 position of glycerophospholipids to give rise to fatty acids and lysophospholipids. The mammalian genome encodes more than 50 PLA2s or related enzymes, which are classified into several subfamilies on the basis of their structures and functions. From a general viewpoint, the PLA2 family h...
