MMP9 and myocardial infarction: Using NCCM, 17 differential control capability genes (DCCGs) related to AMI were identified, 14 of which (NR4A3 [15], THBS1 [16,17], CXCL3 [18], ITLN1 [19,20], CLEC4D [21], LRG1 [22], IRAK3 [23,24], HBEGF [25], MMP9 [26,27], NLRP3 [28,29,30], EDN1 [31], VNN3 [24], and PDK4 [32]) were significantly related to the growth, proliferation, and repair of AMI/MI cells, and BCL6 [33] was indirectly related.
