Cisplatin and Exogenous Hydrogen Sulfide Inhibit the Progression of Osteosarcoma via EGFR/P13K/Akt Signaling Pathway

We attempted to analyze the effects of cisplatin and exogenous hydrogen on the invasion and proliferation of human osteosarcoma cells through EGFR/P13K/Akt signaling pathway. The effects of exogenous hydrogen sulfide and cisplatin on the invasion, apoptosis and proliferation of MG-63 cells were detected by transwell chamber invasion experiment, flow cytometry and CCK-8 method. After 24 and 48 hours of drug action, the inhibition rate of cell proliferation was significantly higher than in the combined treatment. The number of cells decreased significantly, compared with the control group. Western blotting and qRT-PCR showed that the expression of Akt mRNA in MG-63 cells treated with cisplatin+ hydrogen sulfide at different concentrations for 48 hours decreased. The expression of Akt, P13K and EGFR were decreased Flow cytometry analysis showed that after the drug treatment of MG-63 cells, the S phase of cisplatin and cisplatin+ exogenous hydrogen concentrations with different prolonged concentrations was significantly shortened phase and the G0/G1 was significantly, and the apoptosis rate of each group was significantly increased. Cisplatin and exogenous hydrogen sulfide can synergistically inhibit the proliferation and invasion of human osteosarcoma MG-63 cells, and regulate the apoptosis mechanism of MG-63 cells through EGFR/P13K/Akt signaling pathway.
