BACKGROUND/AIMS The role of prostaglandin E2 (PGE2) in the modulation of cell growth is well established in colorectal cancer. The aim of this study was to elucidate the significance of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) down-regulation on the prognosis of hepatocellular carcinoma (HCC) patients. METHODS The expression of 15-PGDH in HCC cell lines and resected HCC tissues was inv...
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...
The present study was designed to characterize prostaglandin dehydrogenase (PGDH) mRNA expression in critical intrauterine tissues of pregnant baboons in late gestation and at spontaneous labor. In addition, we determined regulatory effects of betamethasone in vivo on chorionic and placental PGDH mRNA expression. PGDH mRNA was present in chorion, decidua, lower uterine segment, fundal myometriu...
BACKGROUND Prostaglandins (PGs) have short existence in vivo because they are rapidly metabolized by NAD+-dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) to 15-ketoprostaglandins. Inhibition of 15-PGDH causes elevated level of PGE2 in cellular system. It will be valuable for the therapeutic management of diseases requiring elevated PGE2 levels, like wound healing. OBJECTIVE Ninety-e...
The aim of the present study was to construct the eukaryotic expression vector pcDNA3.1/15-PGDH. The vector was used to transfect mouse murine forestomach carcinoma (MFC) cancer cells and observe the effects of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) on the proliferation of MFC. pcDNA3.1/15-PGDH was constructed using gene recombination technology and the vector was used to transfect MFC...
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...
Helicobacter pylori (H. pylori) infection induces a chronic inflammatory response, which promotes gastric carcinogenesis. 15-Hydroxyprostaglandin dehydrogenase (15-PGDH) plays a key role as a tumor suppressor in gastrointestinal cancers. The aim of this study was to elucidate the role of 15-PGDH in gastric carcinogenesis associated with H. pylori. 15-PGDH expression in gastric biopsies from H. ...
Preclinical and clinical evidence shows that cyclooxygenase-2 (Cox-2)-mediated prostaglandin E(2) (PGE(2)) overexpression plays an important role in tumor growth, metastasis, and immunosuppression. It has been shown that expression of NAD(+)-linked 15-hydroxyprostaglandin dehydrogenase (15-PGDH), a key enzyme responsible for PGE(2) inactivation, is suppressed in the majority of cancers, includi...
