Three-dimensional genome architecture in intrahepatic cholangiocarcinoma

Abstract Purpose: Intrahepatic cholangiocarcinoma (ICC) is a common primary hepatic tumors with a 5-year survival rate of less than 20%. Therefore, it is crucial to elucidate the molecular mechanisms of ICC. Recently, the advance of high-throughput chromosome conformation capture (Hi-C) technology help us look insight into the three-dimensional (3D) genome structure variation during tumorigenesis. However, its function in ICC pathogenesis remained unclear. Methods: Hi-C and RNA-sequencing were applied to analyze 3D genome structures and gene expression in ICC and adjacent
