Yan et al. (2019) and Yan et al. (2019) reported that high expression of ERO1A in cholangiocarcinoma (CCA) was associated with clinical and pathological stages of CCA. It is also postulated that ERO1A promotes growth, migration and invasion of tumor cells through the Wnt/catenin pathway (Han et al., 2018). SLC35A3 is a pathogenic gene of T-cell lympho-blastoma (López-Nieva et al., 2019). This evidence concerns the gene ERO1A and cholangiocarcinoma.
