Inhibition of CDK9 improves colonic epithelial dysfunction in DSS-induced ulcerative colitis mice by blocking the IL-6/STAT3 signaling pathway.
BACKGROUND Ulcerative colitis (UC) is driven by relentless mucosal inflammation and epithelial barrier compromise. Cyclin-dependent kinase 9 (CDK9) governs transcriptional elongation, yet its therapeutic potential in restoring the intestinal barrier via the STAT3 signaling axis remains underexplored. METHODS The effe...
