CXCL2 and myocardial infarction: The results showed that L1β, S100A12, TLR2, CXCL1, and CCL4 were highly expressed in myocardial infarction samples, consistent with previous analysis, while the expression level of the gene CXCL2 had no significant difference between the 2 groups, which may be due to our insufficient sample size, the result is shown in Figure 5A–F.
