Outline of Final Research Achievements |
Hyperglycemia is associated with chronic low-grade systemic inflammation. In this study, we examined the effects of high-glucose on the regulation of inflammation by the circadian clock gene, Rev-erbα. High-glucose-cultured macrophages showed an increased expression of phosphorylated Rev-erbα in the nucleus as compared low glucose-cultured cell, although such differences were not observed at the mRNA level. O-linked N-acetylglucosamine (O-GlcNAc) transferase knockdown abolished the high glucose-induced reduction of proteasome activity as well as nuclear accumulation of Rev-erbα. In addition, Rev-erbαknockdown significantly recovered the attenuation of lipopolysaccharide-stimulated production of IL-10 in response to high-glucose culture. These findings suggest that high-glucose condition induces the nuclear accumulation of Rev-erbα via reducing proteasome activity, resulting in the increased inflammation by the suppression of IL-10 expression.
