Specifically, the dynamic conformational changes caused by the interaction between GR and different ligands and co regulatory factors not only demonstrate the diversity of GR activity, but also provide a new perspective for understanding its role in cell specific gene regulation. In addition, the atypical dimerization pattern of GR ligand binding domain (LBD) and its interactions with DNA and other proteins further demonstrate the complexity of GR mediated transcriptional regulation. These findings are of great significance for a deeper understanding of the role of GR in physiological and pathological processes, as well as for the development of novel therapies for GR. 3 Evaluation of the Research This study provides a profound insight into the signaling mechanism of glucocorticoid receptor (GR) by combining high-resolution structural analysis and biochemical techniques, particularly in its interaction with chromatin and ligand binding induced allosteric effects. By revealing the dynamic allosteric communication between GR ligand binding domain (LBD) and DNA binding domain (DBD), and how it affects the regulatory role of GR on target genes, this work provides an important molecular basis for understanding the disease mechanisms mediated by GR and developing new GR targeted drugs. However, although these findings deepen our understanding of GR activity regulation, further research and validation are needed to fully utilize this knowledge to develop GR agonists and antagonists with selectivity and fewer side effects. 4 Conclusions This study delves into the complex mechanisms of glucocorticoid receptor (GR) signaling and its potential applications in the treatment of inflammation and certain cancers. Special attention was paid to the interaction between GR and chromatin, conformational communication in GR structure, and bidirectional communication between ligands and co regulatory factors. Through structural and molecular biology methods, novel insights into the atypical dimerization patterns of GR ligand binding domains (LBD) and their impact on GR function have been revealed, providing possibilities for the development of novel GR ligands with specific therapeutic effects and reduced side effects. These findings are of great significance for understanding the mechanism of action of GR in cells and developing new therapeutic strategies, especially in the pursuit of more precise and safe drug therapies. 5 Access the Full Text Clarisse D, Van Moortel L, Van Leene C, et al.
