YTHDF2 and non-small cell lung carcinoma: To investigate the function of YTHDF2 in NSCLC cells, we knocked down YTHDF2 using siYTHDF2–1 and siYTHDF2–2 (knocking down YTHDF2 using siYTHDF2–1 was more effective than siYTHDF2–2, so siYTHDF2–1 was used to carry out then subsequent experiments) or overexpressed the protein by transfecting A549 and H1299 cells with a plasmid encoding Flag-YTHDF2 (Fig. 4d, Additional file 7: Fig. S6d, e).
