15-hydroxyprostaglandin dehydrogenase is down-regulated in gastric cancer.
PURPOSE We have investigated the expression and regulation of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) in gastric cancer. EXPERIMENTAL DESIGN Clinical gastric adenocarcinoma samples were analyzed by immunohistochemistry and quantitative real-time PCR for protein and mRNA expression of 15-PGDH and for methylation status of 15-PGDH promoter. The effects of interleukin-1beta (IL-1beta) an...
متن کاملDecreased Expression of 15-hydroxyprostaglandin Dehydrogenase in Gastric Carcinomas
PURPOSE Gastric carcinoma tissues release high level of prostaglandin E2 (PGE2) when compared to non-neoplastic mucosa, and cyclooxygenase-2 (COX-2), which is the rate-limiting enzyme in prostaglandin (PG) biosynthesis, is often overexpressed in gastric carcinomas and during gastric carcinogenesis. However, little is known about the expression of 15-hydroxyprostaglandin dehydrogenase (15-PGDH),...
متن کاملRelationship between 15-hydroxyprostaglandin dehydrogenase and gastric adenocarcinoma
PURPOSE Prostaglandin E2 (PGE2) is a contributory carcinogen in gastric adenocarcinoma. 15-Hydroxyprostaglandin dehydrogenase (15-PGDH) catabolizes PGE2 by oxidizing its 15(s)-hydroxy group. The aim of this study was to investigate the expression of 15-PGDH in gastric adenocarcinoma tissue and the relationship between 15-PGDH expression and clinicopathologic features of gastric adenocarcinoma. ...
متن کاملGenetic Variation in 15-Hydroxyprostaglandin Dehydrogenase and Colon Cancer Susceptibility
BACKGROUND 15-Hydroxyprostaglandin dehydrogenase (15-PGDH) is a metabolic antagonist of COX-2, catalyzing the degradation of inflammation mediator prostaglandin E2 (PGE2) and other prostanoids. Recent studies have established the 15-PGDH gene as a colon cancer suppressor. METHODS We evaluated 15-PDGH as a colon cancer susceptibility locus in a three-stage design. We first genotyped 102 single...
متن کاملPrognostic Implication of 15-Hydroxyprostaglandin Dehydrogenase Down-Regulation in Patients with Colorectal Cancer
PURPOSE Prostaglandin (PG) E2 is known to be closely related to cancer progression and is inactivated by 15-hydroxyprostaglandin dehydrogenase (PGDH). 15-PGDH is shown to have tumor suppressor activity and to be down-regulated in various cancers, including colorectal cancer (CRC). Therefore, we evaluated the expression of 15-PGDH and its prognostic effect in patients with CRC. METHODS 15-PGDH...
