Using transcriptome sequencing technology (RNA sequencing, RNA-seg), the study identified 52 gene targets related to myocardial ischemic infarction, of which 21 were inflammation-related genes, and 16 were genes related to the MAPK cascade reaction, and it was further found that salvianolic acid A could reduce the expression of inflammatory factors such as IL-18, IL-6 and TNF-α, increase the quantity of thioredoxin (Trx) and inhibit the activation of JNK pathway, thus inhibiting apoptosis and inflammatory response, and alleviating the effects of myocardial infarction (227). The gene discussed is IL18; the disease is myocardial infarction.
