Abstract:

N(6)-methyladenosin (m(6)A) is one of the most pervasive modification of mRNA ineukaryotes and the m(6)A methyltransferases and demethylases play critical roles inmany types of cancer. However the role of m(6)A-binding proteins in cancer remainselusive. Here we report that the down-regulation of YTHDF2 was specifically inducedby hypoxia in hepatocellular carcinoma (HCC) cells, and that overexpression ofYTHDF2 suppressed cell proliferation, tumor growth and activation of MEK and ERK inHCC cells. Mechanistically, YTHDF2 directly bound the m(6)A modification site ofEGFR 3&#39;-UTR to promote the degradation of EGFR mRNA in HCC cells. This is the firstreport showing that YTHDF2 may act as a tumor suppressor to repress cellproliferation and growth via destabilizing the EGFR mRNA in HCC.CI - Copyright © 2018 The Author(s).
