Lidocaine inhibits the lung cancer progression through decreasing the HIST1H2BL levels via SIRT5 mediated succinylation

Abstract

Lung cancer is a malignant tumor originating from the bronchial mucosa or gland of the lung. Recently, lidocaine, a widely used amide local anesthetic, was demonstrated to inhibit many cancer progression. This research was performed to explore the specific mechanism of lidocaine in the lung cancer progression. The human normal lung epithelial cells (BEAS-2B), and NSCLC cell lines (A549 and H1299) were used and treated with lidocaine in this study. The cell biological behaviors were detected by CCK-8, wound healing and transwell assay. Besides, the mRNA and protein levels of related genes were detected by western blot. The results showed that lidocaine treatment significantly decreased the cell viability and migration of the A549 and H1299 cells. Furthermore, the lidocaine treatment significantly decreased the succinylation and protein levels of HIST1H2BL, which was reversed after SIRT5 knockdown. Additionally, HIST1H2BL knockdown decreased the cell viability and migration of the A549 and H1299 cells, while HIST1H2BL overexpression reversed the effects of lidocaine on the cell viability and migration of the A549 and H1299 cells. In conclusion, lidocaine treatment might inhibited the lung cancer progression through decreasing the SIRT5 mediated succinylation of HIST1H2BL.
