| Research Abstract |
Cholangiocarcinoma (CCA) is a common carcinoma of the liver, and the majority of patients with CCA have a poor prognosis due to the lack of effective non-surgical therapies in addition to its rapid progression and inoperability at the time of diagnosis. The development of novel non-surgical therapeutics that efficiently target CCA could significantly improve the prognosis for patients presenting with CCA. Here, we describe the iteration and characterization of a novel peptide, designated COP35 (CCA-binding oligo-peptide #35) that binds selectively to human CCA identified by bacteriophage biopanning using the intrahepatic cholangiocarcinoma cell line RBE and the normal cholangiocyte cell line MMNK-1. COP35 was found to augment the growth inhibitory effects of 5-FU against RBE cells. Utilizing pull down assay and liquid chromatography, we identify the clathrin heavy chain (CHC) accompanied by GRP78/BiP as a COP35 binding partner. In summary, we identify COP35 as a possible candidate for peptide targeted therapies for CCA.
