Abstract:
Objective:To investigate the effect of bupivacaine on Apelin/APJ pathway and subsequent gene expression in Sprague-Dawley (SD) rat cardiomyocytes.Methods:H9c2 cardiomyocytes were cultured in vitro and treated with 0-1 mmol/L bupivacaine for 6 h. The concentration of Apelin was detected by enzyme-linked immunosorbent assay (ELISA), and the expression of APJ was detected by Western blot; Fifteen adult male SD rats were randomly divided into sham group (sham group), bupivacaine 30 mg/kg group (Bupi group), bupivacaine 30 mg/kg+ [Pyr 1] apelin-13 0.15 mg/kg (Bupi-A) group. After corresponding treatment, myocardial tissue was taken to detect the expression of Apelin and APJ, and high-throughput sequencing was performed. Results:Western blot and ELISA results showed that bupivacaine down regulated the expression of Apelin and APJ in H9c2 cardiomyocytes (all P<0.05). The expression levels of Apelin and APJ in the myocardial tissue of SD rats in Bupi group were lower than those in sham group (all P<0.05). The expression of Apelin in myocardial tissue of Bupi-A group was higher than that of Bupi group ( P=0.006), but the expression of APJ had no significant difference ( P>0.05). High throughput sequencing revealed that compared with sham group, the top five differentially expressed genes that were significantly upregulated in Bupi group but significantly downregulated in Bupi-A group were ubiquinone NADH dehydrogenase Fe-S protein 3, enolase 1, aquaporin 1, ATP synthase F0 complex C subunit 1 lipid binding protein, and peroxidase 2 (all P<0.001); The top five genes that were significantly down regulated in Bupi group but significantly up-regulated in Bupi-A group were mesothelin, Rho GTPase activating protein 29, sten20 like kinase, carbonic anhydrase, and paraplatelet lysin (all P<0.001). These genes were associated with increased cardiomyocyte apoptosis, energy metabolism disorders and exercise attenuation. Conclusions:bupivacaine can reduce the expression of Apelin, leading to the changes of gene expression related to increased apoptosis, energy metabolism disorder and exercise attenuation in rat cardiomyocytes.
