Further, data retrieved from the TCGA database suggest significantly higher expression levels of fibroblast growth factor receptor 4 (FGFR4) and platelet‐derived growth factor subunit B (PDGFB), as well as lower levels of caspase 9 (CASP9) and serum‐ and glucocorticoid‐regulated kinase (SGK1) in CRC than adjacent normal tissues (Figure 5B), of which the adjusted trends were consistent with RNA‐seq profile (Figure 5C). The gene discussed is SGK1; the disease is colorectal carcinoma.
