The findings indicated that the levels of the genes reported as phenotypic markers for cholangiocarcinoma, including Epcam, Kit, Krt7, Krt19, and Muc1 [16,17,18,19,20], were upregulated, suggesting that the cancerous lesions in the liver appeared to be cholangiocarcinoma. This evidence concerns the gene KRT7 and cholangiocarcinoma.
