TGFB1 and myocardial infarction: ELISA detection of serum samples revealed that compared with the Sham group, the serum TGF-β1 level in the MI group was significantly increased, and this increase was further enhanced in the MI-LncRNA-IH group (Fig. 6G), which was consistent with the changes in cardiac tissue, suggesting that LncRNA-IH can promote the systemic activation of the TGF-β1 signaling pathway.
