EHF and cholangiocarcinoma: Similarly, genes that encode proteins associated with cell growth and metastasis, e.g., mucin 13 (MUC13), carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5), FXDY3, epithelial cell adhesion molecule (EPCAM), transmembrane channel-like 5 (TMC5), and ets homolog factor (ETH) are overexpressed, which corroborate previous reports in CCA (Subrungruanga et al., 2013).
