The CPTAC dataset was used to examine differences in GRWD1 protein levels in 7 tumor tissues, and it was revealed that GRWD1 protein levels were higher in clear cell renal cell carcinoma (ccRCC), colon cancer, and LUAD than in adjacent normal tissues (Figure 1(c), P < 0.01). This evidence concerns the gene GRWD1 and malignant colon neoplasm.
