For instance, Song et al. demonstrated that exosomal miR-4443, through METTL3-mediated regulation of FSP1 m6A modification, enhances cisplatin resistance in non-small cell lung cancer (NSCLC) via the m6A-ferroptosis axis (Song et al., 2021). The gene discussed is METTL3; the disease is non-small cell lung carcinoma.
