Consistently, YTHDF1 loss in GC tumors led to recruitment of mature dendritic cells (DCs) with increased MHCII expression and interleukin-12 (IL-12) secretion, which in turn, promoted CD4+ and CD8+ T cells infiltration with increased interferon-γ (IFN-γ) secretion. This evidence concerns the gene YTHDF1 and gastric cancer.
