Moreover, NP69 cells stably expressing a miR-449b inhibitor (NP69-anti-miR-449b) had increased the sensitivity to cisplatin (Supplementary Figure S2f), confirming that miR-449b, and potentially TGFBI, has a role in cisplatin resistance in NPC cells. The gene discussed is TGFBI; the disease is nasopharyngeal carcinoma.
