Abstract:
Objective: To investigate whether galangin (Gal) affects the proliferation, migration, invasion and apoptosis of osteosarcoma MG63 cells by regulating the cGAS/STING signaling pathway. Methods: Human osteosarcoma MG63 cells were cultured in vitro and treated with Gal at concentrations of 0, 5, 15, 25, 50, 100 and 200 μmol/L for 48 hours, and the effect of Gal on cell viability was detected by CCK-8 method. MG63 cells were divided into the control group (untreated cells), the Gal low concentration group (Gal-L group, treated with 50 μmol/L Gal), the Gal high concentration group (Gal-H group, treated with 100 μmol/L Gal), and the Gal-H+STING inhibitor group (Gal-H+H-151 group, treated with 100 μmol/L Gal+8 μmol/L H-151). EdU staining method, scratch healing test, Transwell chamber method and flow cytometry were used to detect cell proliferation, migration, invasion and apoptosis of cells in each group. Western blot was applied to detect the expression levels of cGAS and STING proteins in cells of each group. Results: Compared with the control group, the proliferation activity, migration, and invasion abilities of the cells in the Gal-L and Gal-H groups were significantly decreased (all PPPPConclusion: Gal may inhibit the proliferation, migration and invasion and promote the apoptosis of osteosarcoma cells by activating the cGAS/STING signaling pathway.
