Moreover, the increased tumor size and lung metastatic foci induced by YTHDF2 overexpression were impaired after inhibiting PD‐L1 or VEGFA expression in Hepa1‐6 cells, and these effects were most obvious when both PD‐L1 and VEGFA were downregulated (Figure 3I; Figure S5J, Supporting Information). Here, CD274 is linked to neoplasm.
