The degree values of the first 30 genes are shown in Figure 4B, which includes RAC-alpha serine/threonine-protein kinase (AKT1), Tumor necrosis factor (TNF), Tumor Protein P53 (TP53), Interleukin-6 (IL-6), Transcription Factor AP-1(JUN), Sarcoma (SRC), Epidermal growth factor receptor (EGFR), Heat Shock Protein 90 Alpha Family Class A Member 1 (HSP90AA1), Vascular endothelial growth factor A (VEGFA), and Caspase 3 (CASP3) etc. The MCODE plug-in of Cytoscape was then used to generate PPI network clusters of T2DM targets, which are shown in Figure 4C. The gene discussed is HSP90AA1; the disease is type 2 diabetes mellitus.
