Outline of Final Research Achievements |
We investigated the physiological role of the metabolism of cyclopentenone-prostaglandin, mediated by prostaglandin-conjugating enzymes, sulfotransferase and glutathione transferase, in the intestinal tract. As a result, the prostaglandin metabolites negatively regulated the prostaglandin receptors involved in inflammation and cancer and suppressed the expression of inflammatory cytokines. In addition, the effects of prostaglandin-conjugating enzymes knockdown on the inflammatory cytokine expression was confirmed by in vivo knockdown experiments, implying that prostaglandin-conjugating enzymes may play a role in the regulating the intestinal immune system. Furthermore, this study suggested that the conjugation enzymes regulate the homeostasis of villi by controlling the apoptotic action of prostaglandin peroxide metabolites.
