Consistently, from the results in TCGA database, increased CKIP‐1 expression was also found in BRCA, cholangiocarcinoma (CHOL), kidney renal clear/papillary cell carcinoma (KIRC/KIRP), liver hepatocellular carcinoma (LIHC), implying that CKIP‐1 may also be implicated in regulating the progression of these types of tumours positively. This evidence concerns the gene PLEKHO1 and cholangiocarcinoma.
