YTHDF2 and glioblastoma: Kaplan–Meier analysis of the overall survival time in GBM patients demonstrated that the survival rate of the patients with high level of YTHDF2 was lower than that of the patients with YTHDF2 low level (Figure 1c), and the high expression of YTHDF2 was positively correlated with the chemotherapy resistance (Supplementary table 2 & Figure 1d).
