Correlation analysis of immune cells and genes showed the highest negative correlation for YTHDF2/neutrophil in blood samples; consistent with one study that found METTL3 cooperating with YTHDF2 can inhibit papillary thyroid cancer progression via m6A/c-Rel/IL-8-mediated neutrophil infiltration [37]. This evidence concerns the gene YTHDF2 and thyroid gland papillary carcinoma.
