1 Proteomic analyses of Sirt1-mediated cisplatin resistance in OSCC cell line. Cisplatin sirtuin 1 Homo sapiens
2 Sirt1, a class III histone deacetylase, was linked to cisplatin resistance in several cancer types; however, the underlying mechanism is still unclear. Cisplatin sirtuin 1 Homo sapiens
3 Here, we demonstrated that overexpression of Sirt1 survived OSCC cell line Tca8113 under cisplatin treatment. Cisplatin sirtuin 1 Homo sapiens
4 Notably, BML-210, a chemical inhibitor of class III histone deacetylase, significantly abolished Sirt1-mediated cisplatin resistance in Tca8113 cells. Cisplatin sirtuin 1 Homo sapiens
5 Further, inactivation of endogenic Sirt1 by nicotinamide markedly increased chemo-sensitivity in cisplatin resistant sub-cell line Tca8113/CDDP. Cisplatin sirtuin 1 Homo sapiens
6 Further, inactivation of endogenic Sirt1 by nicotinamide markedly increased chemo-sensitivity in cisplatin resistant sub-cell line Tca8113/CDDP. Cisplatin sirtuin 1 Homo sapiens
7 Finally, we showed that Sirt1 could prevent cisplatin-induced ROS accumulation in Tca8113 cells. Cisplatin sirtuin 1 Homo sapiens
8 Our findings are considered as a significant step toward a better understanding of Sirt1-mediated cisplatin resistance. Cisplatin sirtuin 1 Homo sapiens
