The two studies also showed YTHDF2 could recognize m6A-modified sites of lncRNA KCNQ1OT1 or PVT1 and regulate their stability [51, 63], but whether ALKBH5 regulates the stability of PVT1 via YTHDF2 in lung cancer cells remains to be examined further. The gene discussed is ALKBH5; the disease is lung carcinoma.
