WebAug 3, 2024 · Background: Non-small cell lung cancer (NSCLC) cells derived intracellular and extracellular programmed cell death ligand 1 (PD-L1) promoted cancer progression and drug resistance, and facilitated tumor immune evasion. However, the detailed molecular mechanisms are still largely unknown. WebThe PD-L1 could reduce the level of cell damage caused by cisplatin. In addition, we found PD-L1 can also up-regulate the expression of P-gp. Mechanistically, PD-L1 activated the PI3K/AKT signaling pathway in which PI3K/AKT pathway inhibition attenuated the upregulation of P-gp.
WebOct 22, 2024 · Cisplatin is an alkylating agent which induces DNA damage through the formation of cisplatin-DNA adducts, leading to cell cycle arrest and apoptosis. In the management of advanced OSCC, cisplatin-based chemotherapy or chemoradiotherapy has been considered as the first-line treatment. WebPD-L1 increases resistance to radiation or cisplatin by stabilizing NBS1, BRCA1, and other proteins that facilitate the repair of DNA damage ( 5 ). PD-L1 also diminishes IFN-β cytotoxicity by inhibiting an IFN-β–induced STAT3/caspase-7–dependent pathway ( 6 ).
