In addition, ALKBH5 suppressed the degradation of lncRNA plasmacytoma variant translocation 1 (PVT1), which was up-regulated in osteosarcoma tissues and cells, thus promoting the osteosarcoma cell proliferation in vitro and tumor growth in vivo through inhibiting the binding of m6A reader YTHDF2 in PVT1 [40]. Here, YTHDF2 is linked to osteosarcoma.
