GSK3B and Insulin resistance: The protein–protein interaction (PPI) and target–pathway (TP) network analysis identified key hub genes, including EGFR, SRC, AKT1, TNF, PPARG, PIK3R1, RELA, INSR, GSK3B, PIK3CG, FYN, PTBIN, and PPARA, with critical roles in insulin resistance and T2DM-relevant pathways.
