Fibroblast growth factor receptor 4 (FGFR4) is over-expressed in many cancers, including cholangiocarcinoma (CCA). FGFR4 is activated by fibroblast growth factor ligand 19 (FGF19) and plays a critical role in CCA progression. An intracellular cleaved product of FGFR4, referred as R4-ICD (FGFR4 intracellular domain) is also overexpressed in CCA. However, the specific role of R4-ICD in CCA is unknown. In this study, we hypothesized that FGFR4 and R4-ICD play a role in cell proliferation, cell survival and metastasis in CCA. To test this, FGFR4 and R4-ICD were cloned into a cholangiocarcinoma cell line (HuCCT-1) that does not endogenously express FGFR4. …

Role Of Ezrin In Colorectal Cancer Cell Survival Regulation, Premila Leiphrakpam
Theses & Dissertations
Colorectal cancer (CRC) is the second most common cause of cancer related deaths in the United States, mainly due to metastasis to the distant organ sites. However, the molecular basis of CRC metastasis is poorly understood. Therefore, identification and characterization of novel potential anti-cancer therapeutic targets CRC is of urgent need. Utilizing a 2D-DIGE proteomics approach ezrin was identified as a protein that is differentially expressed between primary colon tumors xenografts, orthotopically implanted in athymic nude mice, and corresponding and liver metastatic deposits. Ezrin, a cytoskeletal protein belonging to the ezrin–radixin–moesin (ERM) family plays important roles in cell motility, invasion …
