Based on the observed interactions among NEAT1, miR-23a-3p, and Nrf2, we inferred that dendrobium mixture and Met may reduce apoptosis of myocardial cells and improve the function and morphology of heart tissues in rats with DCM by upregulating the expression of NEAT1 through miR-23a-3p and Nrf2. The proposed mechanism for the role of lncRNA NEAT1 in DCM is shown in Figure 7. Here, NFE2L2 is linked to familial dilated cardiomyopathy.
