Gene set enrichment analysis (GSEA) was performed after dividing the bladder cancer specimens from the TCGA dataset into the high YTHDC1 expression group and low YTHDC1 expression group, and it showed that YTHDC1 was negatively correlated with the KEGG_BLADDER_CANCER signaling pathway (P = 0.008, NES = −1.83) (Fig. 1c). The gene discussed is YTHDC1; the disease is urinary bladder cancer.
