A survival analysis was performed on the DEGs, and XKR9 was found to have a significant effect on survival when considering all of the cancer types combined (Fig. 2C) as well as in three specific cancer types (kidney renal papillary cell carcinoma (KIRP), kidney chromophobe (KICH), and liver hepatocellular carcinoma (LIHC)) (Figs S1A, S1B, and S1C). Here, XKR9 is linked to cancer.
