This study investigated the potential therapeutic effects of perillaldehyde (PAE) on diabetic cardiomyopathy (DCM) through network pharmacology and molecular docking. The results showed that PAE can improve cardiac function, reduce myocardial injury and apoptosis in DCM rats, and inhibit P-GSK-3 beta expression by upregulating miR-133a-3p.
Diabetic cardiomyopathy (DCM) is part of the most important causes of death from cardiovascular disease. Perillaldehyde (PAE), a major component of the herb perilla, has been shown to ameliorate doxorubicin-induced cardiotoxicity, but it is unclear whether PAE exerts beneficial effects on DCM. Exploring the potential molecular mechanisms of PAE for the treatment of DCM through network pharmacology and molecular docking. The SD rat type 1 diabetes model was established by a single intraperitoneal injection of streptozotocin (60 mg/kg), the cardiac function indexes of each group were detected by echocardiography; the morphological changes, apoptosis, protein expression of P-GSK-3 beta (S9), collagen I (Col-I), collagen III (Col-III) and alpha-smooth muscle actin (alpha-SMA), and miR-133a-3p expression levels were detected. An DCM model of H9c2 cells was established in vitro and transfected with Mimic and Inhibitor of miR-133a-3p. The results showed that PAE ameliorated cardiac dysfunction, reduced fasting glucose and cardiac weight index, and improved myocardial injury and apoptosis in DCM rats. It reduced high glucose-induced apoptosis, promoted migration and improved mitochondrial division injury in H9c2 cells. PAE decreased P-GSK-3 beta (S9), Col-I, Col-III and a-SMA protein expression and upregulated miR-133a-3p expression levels. After miR-133a-3p Inhibitor treatment, the expression of P-GSK-3 beta (S9) and a-SMA expression were significantly increased; after miR-133a-3p Mimic treatment, the expression of P-GSK-3 beta (S9) and a-SMA decreased significantly in H9c2 cells. It suggests that the mechanism of action of PAE to improve DCM may be related to the upregulation of miR-133a-3p and inhibition of P-GSK-3 beta expression.
