タイトル Epoxide hydrolases JHEH1 and JHEH2 deficiency impairs glucose metabolism in Drosophila.
ジャーナル Biochem Biophys Res Commun
Abstract Epoxide hydrolases (EHs) play pivotal roles in detoxification, catabolism, and signaling by converting epoxides into diols and have been implicated in several diseases, such as cancers and diabetes. EH homologs in insects are designated as Juvenile hormone epoxide hydrolases (JHEHs) due to their catalytic activity toward Juvenile hormone (JH). However, the biological function of JHEHs has been controversial in the fruit fly Drosophila melanogaster. In this study, we generated and characterized flies deficient in Jheh1 and Jheh2 genes. We found that Jheh1/2 deficiency caused a developmental delay and enhanced the growth retardation effects of caffeine and paraquat. Additionally, we observed that the deficiency reduced tolerance to cold stress. These results indicate that JHEHs are required for growth promotion and stress tolerance. Metabolomic and transcriptomic analyses revealed that Jheh1/2 deficiency impaired glucose metabolism and downregulated genes involved in glycolysis and the TCA cycle. Furthermore, transgenic overexpression of Jheh1 increased glycolytic metabolites and restored the Jheh1/2 deficiency-associated phenotype. These results demonstrate that JHEHs play a crucial role in glucose metabolism in Drosophila, providing a valuable model to study the mechanisms underlying the function of EHs in energy metabolism.
