GenomicsMassive parallel sequencing uncovers actionable FGFR2-PPHLN1 fusion and ARAF mutations in intrahepatic cholangiocarcinoma
Intrahepatic cholangiocarcinoma (iCCA) is a fatal bile duct cancer with dismal prognosis and limited therapeutic options. By performing RNA- and exome sequencing analyses we have discovered a novel fusion event, FGFR2-PPHLN1 (16%), and damaging mutations in the ARAF oncogene (11%). Methods: mRNA and...

TranscriptomicsLow-power photodynamic therapy induces survival signaling in cultured hilar cholangiocarcinoma cells
Photodynamic therapy (PDT) of solid cancers comprises the administration of a photosensitizer followed by illumination of the photosensitizerreplete tumor with laser light. This induces a state of local oxidative stress, culminating in the destruction of tumor tissue and microvasculature and inducti...

TranscriptomicsMolecular classification of human cholangiocarcinoma
Transcriptomic profiling Background Cholangiocarcinoma accounts for 5-10% of primary hepatic cancers. The etiology is unclear and patients are often diagnosed without risk factors. Resection is the only curative treatment although patients frequently remain undiagnosed until advanced stage of disea...

ProteomicsTWEAK/Fn14 signalling promotes cholangiocarcinoma niche formation and progression
Cholangiocarcinoma is a cancer of the hepatic bile ducts that is typically detected at a stage too advanced for resection. Additionally, chemotherapy is of limited efficacy, hence, novel therapeutic approaches are urgently required, including targeting of the cancer stroma. A macrophage-derived sign...

TranscriptomicsTranscription profiling of human cholangiocarcinoma cells (cholangiocytes) expressing IL-6
The association between chronic inflammation and the development and progression of malignancy is exemplified in the biliary tract where persistent inflammation strongly predisposes to cholangiocarcinoma. The inflammatory cytokine interleukin-6 (IL-6) enhances tumor growth in cholangiocarcinoma by a...

TranscriptomicsDifferentially expressed miRNAs in xenografts and organoids derived from human cholangiocarcinoma [miRNA]
We established xenografts and organoids derived from human cholangiocarcinoma. To investigate the signature of cancer stem cells, miRNA expression profiles were analyzed in cholangiocarcinoma xenografts and organoids (passage 7). Microarray analyses were conducted in cholangiocarcioma xenografts and...

We established xenografts and organoids derived from human cholangiocarcinoma. To investigate the signature of cancer stem cells, gene expression profiles were analyzed in cholangiocarcinoma xenografts and organoids (passage 7 and 32). Microarray analyses were conducted in cholangiocarcioma xenograf...

TranscriptomicsGene-expression profiles of formalin-fixed, paraffin-embedded human intrahepatic cholangiocarcinoma
BACKGROUND & AIMS: Cholangiocarcinoma, the second most common liver cancer, can be classified as intrahepatic (ICC) or extrahepatic. We performed an integrative genomic analysis of ICC samples from a large series of patients. METHODS: We performed gene expression profile, high-density single nucleot...

TranscriptomicsGenome-Wide Molecular Signature of Cholangiocarcinoma and Its Trandifferentation-Related Genes
Cholangiocarcinoma (CC) is an aggressive tumor that shows a poor survival rate even after resection. The present study aimed at identification of the genome-wide expressed genes related to CC oncogenesis and its sarcomatous transdifferentiation using DNA microarray technology. The differentially exp...
