To elucidate the role of BMI1 in FOXA1-mediated cisplatin sensitivity in NPC, we performed in vitro assays to evaluate cell viability (Fig. 6A, B), migration (Supplementary Fig. 1A, B), and invasiveness (Supplementary Fig. 1C) after BMI1 knockdown in cells with silenced FOXA1. The gene discussed is BMI1; the disease is nasopharyngeal carcinoma.
