BCL9 promotes epithelial mesenchymal transition and invasion in cisplatin resistant NSCLC cells via β-catenin pathway

These findings indicated BCL9 induced the occurrence of EMT and enhancement of stemness, which resulted in cisplatin-resistance and promoted migration in NSCLC cells. Mechanically, Wnt/β-catenin pathway is crucial in BCL9-induced migration, invasion, and chemotherapy resistance.
