To further clarify METTL3’s target gene and the mechanisms by which METTL3 contributes to SCLC chemoresistance, we performed MeRIP-seq on METTL3 knockdown and control H69AR cells, and the GGAC motif was highly enriched in the m6A site of both knockdown and control cells (Fig. 4A). Here, METTL3 is linked to small cell lung carcinoma.
