The results showed that YTHDF1 expression was related to different immune subtypes in BRCA, COAD, HNSC, KIRC, LGG (brain lower grade glioma), LUAD, LUSC, OV (ovarian serous cystadenocarcinoma), PRAD, SKCM (skin cutaneous melanoma), STAD, and UCEC (Figure 3). This evidence concerns the gene YTHDF1 and ovarian serous cystadenocarcinoma.
