Research Backgrounds

Function:

Converts arachidonate to prostaglandin H2 (PGH2), a committed step in prostanoid synthesis. Constitutively expressed in some tissues in physiological conditions, such as the endothelium, kidney and brain, and in pathological conditions, such as in cancer. PTGS2 is responsible for production of inflammatory prostaglandins. Up-regulation of PTGS2 is also associated with increased cell adhesion, phenotypic changes, resistance to apoptosis and tumor angiogenesis. In cancer cells, PTGS2 is a key step in the production of prostaglandin E2 (PGE2), which plays important roles in modulating motility, proliferation and resistance to apoptosis. During neuroinflammation, plays a role in neuronal secretion of specialized preresolving mediators (SPMs), especially 15-R-lipoxin A4, that regulates phagocytic microglia (By similarity).

PTMs:

S-nitrosylation by NOS2 (iNOS) activates enzyme activity. S-nitrosylation may take place on different Cys residues in addition to Cys-526.

Acetylated at Ser-565 by SPHK1. During neuroinflammation, acetylation by SPHK1 promotes neuronal secretion of specialized preresolving mediators (SPMs), especially 15-R-lipoxin A4, which results in an increase of phagocytic microglia.

BV2 cell lines were exposed to the indicated compounds at concentrations of 10, 20 and 40 mM for 24 h in the presence of LPS (1 mg/mL). C6 cell lines were exposed to the indicated compounds at concentrations of 10, 20 and 40 mM for 24 h in the presence of LPS (10 mg/mL). The expression of iNOS and COX-2 was assayed and calculated by image J. Each error bar represents the mean ± SD of three independent experiments. #, p < 0.05 versus the control group; ##, p < 0.01 versus the control group; ###, p < 0.001 versus the control group. *, p < 0.05, **, p < 0.01 when compared to the LPS-treated cells. All data are the mean ± SD of at least three independent experiments.
