This review examines COX-2 (PTGS2) genetic variants and their association with gastric cancer susceptibility. Key variants include rs689466 (OR=1.19, p=0.002), rs20417 (OR=1.26, p<0.001), rs3218625 (OR=1.62, p=0.039), and rs5275 (OR=1.14, p=0.030), which increase gastric cancer risk through enhanced transcriptional activity or mRNA stability. The paper synthesizes data from multiple case-control studies and the authors' own analyses in Chinese populations (296-660 cases each), establishing COX-2 polymorphisms as potential biomarkers for cancer risk stratification.
About PTGS2
Prostaglandin-endoperoxide synthase (PTGS), also known as cyclooxygenase, is the key enzyme in prostaglandin biosynthesis, and acts both as a dioxygenase and as a peroxidase. There are two isozymes of PTGS: a constitutive PTGS1 and an inducible PTGS2, which differ in their regulation of expression and tissue distribution. This gene encodes the inducible isozyme. It is regulated by specific stimulatory events, suggesting that it is responsible for the prostanoid biosynthesis involved in inflammation and mitogenesis. [provided by RefSeq, Feb 2009]
