Considering that the effect of METTL3 on SUCLG2‐AS1 expression may depend on the mediation of m6A readers, common m6A reader proteins, including HUR, HNRNPA2B1, IGF2BP1, IGF2BP2, and IGF2BP3, were silenced in NPC cells, and knockdown efficiency was successfully validated (Figure S3B,R). Here, METTL3 is linked to nasopharyngeal carcinoma.
