Recently, PD-L1 expression has also been found to be regulated by some other m6A regulators in other types of cancer, such as mediated by METTL3 in OSCC (124), by FTO in colon cancer cells (131), and by YTHDF1 and YTHDF2 in NSCLC (136). The gene discussed is YTHDF2; the disease is non-small cell lung carcinoma.
