摘要 |
[Objectives] To investigate whether Ailanthone (AIL) could reverse cisplatin resistance in non-small cell lung cancer (NSCLC) by modulating autophagy pathways in A549/DDP cells. [Methods] Cisplatin-resistant A549/DDP cells were treated with AIL (0.6 μmol/L), cisplatin (50 μg/mL), or their combination. Cell proliferation was assessed by MTT, EdU and colony formation assays; migration by Transwell and wound healing assays; autophagy markers (P62, LC3B, Beclin1, ATG5) by Western blot; LC3B puncta by immunofluorescence; with rescue experiments using rapamycin. [Results] The AIL-cisplatin combination synergistically inhibited proliferation and migration, while downregulating P-gp and MVP. AIL significantly increased P62 accumulation while decreasing LC3B-II, Beclin1 and ATG5. Rapamycin reversed these effects, restoring viability and resistance markers. [Conclusions] AIL reverses cisplatin resistance in NSCLC by inhibiting autophagy through P62/LC3B regulation, offering a promising therapeutic strategy for refractory NSCLC. |
