YTHDF2 and neoplasm: In the CPTAC database, the YTHDF2 expression level was substantially increased in tumour tissues (Figure 1E), and the subgroup analysis revealed that this abnormal expression pattern was observed in most patients, except for some patients aged less than 40 years and greater than 80 years; in addition, the increase was not significant in patients with stage IV tumours (Figures 1F–H).
