These miRNAs converge on central target genes such as STAT3, PTEN, BCL2, MYC, RAF1, EGFR, IRS1, SMAD4, FOXO3, GLUT4, AKT1, and CTNNB1, regulating pathways of insulin signaling, glucose metabolism, apoptosis, inflammation, and fibrosis.<h4>Discussion</h4>Shared miRNAs act as molecular nodes linking immunity and metabolism, providing a framework for biomarker development in TB-T2DM comorbidity. Here, STAT3 is linked to type 2 diabetes mellitus.
