Administration of cells overexpressing YTHDF1 increased tumour volumes when compared with Vector group (Figure 4A,B; p < 0.0001), while cells knocking‐down YTHDF1 (shYTHDF1‐1, p < 0.0001 and shYTHDF1‐2, p < 0.0001) decreased tumour volumes when compared with shControl group in the xenograft model (Figure 4A,B). Here, YTHDF1 is linked to neoplasm.
