YTHDF1 exhibited a positive correlation with proteasomal protein catabolic process-related factors in GC tissue samples from TCGA cohort (Figures 5D–F and Supplementary Figure S5A), but showed an opposite tendency between gene expression and tumor prognosis, with only ubiquitin-specific protease 14 (USP14) upregulation indicating a shorter overall survival in patients with GC (Figures 5G–J and Supplementary Figure S5B). Here, YTHDF1 is linked to gastric cancer.
