Figure 6(a) visualizes the top twenty myocardial infarction targets of salvianolic acid A in accordance with the degree, comprising SRC, CTNNB1, PIK3CA, AKT1, RELA, EGFR, FYN, ITGB1, MAPK8, NFKB1, ESR1, PLG, MAPK14, ERBB2, IL6, ITGB3, ITGAV, KDR, MTOR, and APP. With cytoHubba plugin, ten hub myocardial infarction targets of salvianolic acid A were determined, covering SRC, CTNNB1, PIK3CA, AKT1, RELA, EGFR, FYN, ITGB1, MAPK8, and NFKB1 (Figure 6(b)). The gene discussed is APP; the disease is myocardial infarction.
