miR-21, miR-22, miR-24, miR-133, miR-181a, and miR-195 can be upregulated in response to MI and are involved in cardiac fibrosis by tumour growth factor-β (TGF-β) signalling pathway (Hong et al., 2016; Chen et al., 2017; Yuan et al., 2017, 7; Chen P. et al., 2018; Yu et al., 2019; Wang DM. This evidence concerns the gene TGFB1 and myocardial infarction.
