The hub genes calculated by maximal clique centrality (MCC) algorithm with Cytoscape software are FOS (score 32), PTGS2 (score 31), SOCS3 (score 30), MYC (score 29), ZFP36 (score 26), TLR2 (score 9), BTG2 (score 2), ZBTB16 (score 1), THBD (score 1), and RHOBTB1 (score 1), which are considered to be associated with NAFLD-related AF (Figures 2E, F). Here, FOS is linked to atrial fibrillation.
