Abstract

Background and objective: Cholangiocarcinoma (CCA), a liver cancer of bile duct epithelial cells, is a severe health issue in northeastern Thailand. The epithelial-mesenchymal transition (EMT) is a crucial process in the development of CCA. To comprehend oncogenic EMT in CCA, several newly found EMT factors are being explored in these underlying pathways. This narrative review explained the latest in vitro and in vivo findings on the molecular mechanisms of 21 new EMT-related proteins that affect CCA progression.

Methods: We evaluated the PubMed database for relevant articles that fulfilled our criteria for investigating the molecular pathways of the novel EMT markers involved in oncogenic EMT and how they contribute to CCA development, including cell proliferation, apoptosis, invasion, migration, and chemoresistance.

Key content and findings: We discuss the potential of these new EMT markers as diagnostic, prognostic, and therapeutic indicators for CCA and describe their underlying mechanisms in the development of the disease. The discovery of several oncogenic EMT proteins and their key signaling pathways and downstream targets will also broaden novel paths of investigation into the diagnosis and targeted treatment of CCA.

Conclusions: The EMT-related proteins that were found are good sources of knowledge and interesting information for future research. The possible ways to treat CCA that could be tested in clinical trials were also discussed.

Keywords: Cholangiocarcinoma (CCA); biomarkers; epithelial-mesenchymal transition (EMT).
