Disease relevance of Hpgd


High impact information on Hpgd

  • Enzymatic activity of 15-PGDH correlates with expression levels and the genetic disruption of 15-Pgdh completely blocks production of the urinary PGE2 metabolite [1].
  • The present study examined a range of normal tissues in the human and mouse and found high levels of 15-PGDH in the large intestine [1].
  • These results suggest that 15-PGDH may decrease the level of proliferative PGE2, induce apoptosis and function like a tumor suppressor [2].
  • 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 NSCLC tumors and adjacent non-malignant tissue from the same patient [2].
  • This suggests that the increased expression of COX-2 and PGE synthase in tumors may work in concert with the decreased expression of 15-PGDH to amplify an increase in tissue levels of proliferative PGE2 [2].

Biological context of Hpgd

  • The cDNA contains a 798 bp open reading frame that codes for a protein of 266 amino acids (M(r) 28775) which shares 87% identity with the human 15-PGDH protein [4].
  • The cDNA for mouse NAD+ dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) was isolated from a lung cDNA library [4].

Associations of Hpgd with chemical compounds

  • Enzymatic degradation of PGE2 involves the NAD+-dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) [1].
  • The enhanced proinflammatory eicosanoids is secondary to increased cyclooxygenase-2 (Cox-2) expression and low levels of prostaglandin/leukotriene catabolic enzyme, 15-hydroxyprostaglandin dehydrogenase (15-PGDH) [5].
  • NAD+-dependent 15-hydroxyprostaglandin dehydrogenase (15-PGDH) catalyzes the oxidation of the 15(S) hydroxyl group of prostaglandins to a 15-keto group resulting in a significant reduction of the biological activities of prostaglandins [6].

Other interactions of Hpgd


Analytical, diagnostic and therapeutic context of Hpgd

  • Northern blot analysis demonstrated that 15-PGDH mRNA is expressed primarily in lung, intestine, stomach and liver [4].
