| Outline of Final Research Achievements |
Glucocorticoids are widely used as anti-inflammatory drugs, the molecular mechanisms involved in this anti-inflammatory effect and associated with serious side effects remain unknown. In this study, we performed the proteomic analysis of post-translational modification on glucocorticoid receptor (GR) and identified a novel O-linked beta-N-acetylglucosamine (O-GlcNAc) modified sites. Moreover, this O-GlcNAcylation was regulated under conditions of glucose concentration in culture medium and detected in nucleus of mouse liver and cerebrum. Based on these results, we propose that this O-GlcNAcylation regulates the tissue-specific transcriptional activity of GR.
