NAD+-linked 15-hydroxyprostaglandin dehydrogenase (15-PGDH) behaves as a tumor suppressor in lung cancer.
It has been reported that two inducible prostaglandin synthetic enzymes, cylooxygenase-2 (COX-2) and microsomal PGE synthase, are over-expressed in non-small cell lung cancer (NSCLC). Using quantitative reverse transcription-polymerase chain reaction, we analyzed RNA levels of the key prostaglandin catabolic enzyme, NAD+-linked 15-hydroxyprostaglandin dehydrogenase (15-PGDH), in 19 pairs of NSC...
متن کامل15-hydroxyprostaglandin dehydrogenase (15-PGDH) prevents lipopolysaccharide (LPS)-induced acute liver injury
The NAD+-dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) catalyzes the oxidation of the 15(S)-hydroxyl group of prostaglandin E2 (PGE2), converting the pro-inflammatory PGE2 to the anti-inflammatory 15-keto-PGE2 (an endogenous ligand for peroxisome proliferator-activated receptor-gamma [PPAR-γ]). To evaluate the significance of 15-PGDH/15-keto-PGE2 cascade in liver inflammation and ti...
متن کاملFocusing downstream in lung cancer prevention: 15-hydroxyprostaglandin dehydrogenase.
Deregulated inflammatory mediators and growth factors seem to act in concert with mutational events in driving malignant transformation and progression, thus contributing to the complex pulmonary environment in the lung at risk for cancer. Pulmonary diseases that are associated with the greatest risk for malignancy are characterized by abundant and deregulated inflammation (1). Profound abnorma...
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 کامل15-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...
