ABSTRACT: The whole study comprises of two patient cohorts. Screening cohort: 40 patients of Germany; validation cohort: 40 patients from Asia. Further, bile duct and CCA cell lines have been analyzed. This dataset contains whole exome sequencing data of 37 tumor/normal pairs from the screening cohort plus an additional relapse tumor of one of those 37 patients. Data was generated on Illumina HiSeq 2000 device in paired-end mode and is stored in BAM file format.

Identification of RNF213 as a potential suppressor of local invasion in intrahepatic cholangiocarcinoma

Project description:Intrahepatic cholangiocarcinoma (ICC) is a lethal cancer arising from intrahepatic bile ducts in the liver. In the intraductal growth (IDG) type, also referred to as intraductal papillary neoplasm of the bile duct (IPNB), a rare subtype of ICC, cancer cells originating within the bile duct usually invade and infiltrate the nearby liver tissues, resulting in local invasion. IPNB can serve as a good disease model to study the mechanism of local invasion, which is the earliest step of metastasis. Here, we aimed to identify the genes associated with local invasion by comparing the somatic mutations of the matched IPNB tissues with and without local invasion from a set of 11 patients using the Ion AmpliSeq Comprehensive Cancer Panel. Somatic mutation profiling analysis identified RNF213 as a potential candidate gene associated with local invasion in ICC patients. We established stable RNF213-knockdown and shControl cholangiocarcinoma (CCA) cell lines (HuCCT1, YSCCC, and KKU-100). Next, the expression profiling of the RNF213-knockdown and shContol CCA cell lines was analyzed by RNA sequencing.

MBD2 regulates the progression and chemoresistance of cholangiocarcinoma through interaction with WDR5

Project description:Background: Cholangiocarcinoma (CCA) is a high malignancy, rapid progression tumor of bile duct. Due to its chemoresistance, it always has an extremely poor prognosis. Therefore, it is still need to detailed elucidation the mechanisms of chemoresistance and find the therapeutic targets. Methods: We analysis the expression of MBD2 in CCA and normal bile duct tissues through public database and immunohistochemical (IHC). The role of MBD2 in CCA cells’ proliferation, migration, chemoresistance ability was validated through CCK-8, plate clone assay, wound healing assay, xenograft mice models. Besides, we construct a primary CCA mice model to further confirm the effect of MBD2. RNA-seq, co-IP-MS were used to find the mechanisms of MBD2 leading to chemoresistance. Results: MBD2 is up-regulated in CCA. It could promote the proliferation, migration and chemoresistance of CCA cells. Mechanistically, MBD2 could directly interact with WDR5, and binding to the promoter of ABCB1, then promote the tri-methylation of H3K4 in this region through KMT2A, active the expression of ABCB1. Knocking down of WDR5 or KMT2A could block the transcriptional activation of ABCB1 by MBD2. MM-102 is a molecular inhibitor that targets the interaction of WDR5 with KMT2A. MM-102 could inhibit the expression of ABCB1 in CCA cells, and decrease the chemoresistance of CCA to cisplatin. Conclusion: MBD2 promote the progress and chemoresistance of CCA through interact with WDR5. MM-102 could effectively block this procedure and enhance the sensitivity to cisplatin of CCA.

aCGH for bile duct cancer

Project description:Assays in bile duct cancer patients showed 984 CNVs in 306 CNV regions (CNVR) distributed throughout all 22 chromosomes. Bile duct cancer patients had a mean of 21.8 gains and 19.2 losses of genes, with an average of 35.9 CNVRs per patient. Frequent sites of gains were at chromosomes 22q11.22, 2p11.2-p.11.1, 14q32.33 and 17q12, whereas frequent sites of losses were at 19q12-q13.43.

Cholangiocarcinoma tissues VS. corresponding normal bile duct tissues

Project description:To identify miRNAs differentially expressed in cholangiocarcinoma,3 human cholangiocarcinoma and their corresponding normal bile duct tissues were obtained from 3 patients after operation with postoperative pathological diagnosed perihilar or distal biliary cholangiocarcinoma miRNAs expression in human cholangiocarcinoma/normal bile duct samples was measured after operation.Three independent experiments were performed using different patients for each experiment.
