Transcription profiling of rat new model of cholangiocarcinoma progression mimicking the human cancer

ABSTRACT: Validation of preclinical models of intrahepatic cholangiocarcinoma progression that reliably recapitulate altered molecular features of the human disease would provide an important resource for suggesting and testing of novel target-based therapies against this devastating cancer. In this study, comprehensive gene expression profiling in a novel orthotopic rat model of intrahepatic cholangiocarcinoma progression was carried out in an effort to identify potential therapeutic targets relevant to the progressive human cancer. Microarray analysis was performed on intrahepatic cholangiocarcinomas formed at 10, 15, and 25 days after bile duct inoculation of neu-transformed rat cholangiocytes (BDEneu cells) into rat liver and on peritoneal metastases at the 25 day time period, compared with non-cancerous right liver lobe from the same animals. Experiment Overall Design: Tumors were collected at 10, 15, 25 days post inoculation from biological triplicates (different rats innoculated simultaneously). Also, biological triplicates of metastatic tumors (Mets) at day 25 were analyzed. Biological triplicates of paired normal right liver lobe (RLL) from the same animals from which tumors/mets were obtained were also analyzed in this study. Thus, a total of 9 rats were used for this study.

Differential gene expression profiling of cultured neu-transformed versus spontaneously-transformed rat cholangiocytes and of corresponding cholangiocarcinomas

Project description:Characterization of preclinical models of intrahepatic cholangiocarcinoma progression that reliably recapitulate altered molecular features of the human disease. Here, we performed comprehensive gene expression profiling of cholangiocarcinoma tumors arising from bile duct inoculation of different grade malignant rat cholangiocytes. Tumors arising from bile duct inoculation of spontaneously-transformed low grade malignant rat BDE1 cholangiocytes (BDEsp cells) compared to tumors arising from the inoculation of high grade malignant erbB-2/neu- transformed BDE1 cholangiocytes (BDEneu cells) into the livers of syngeneic rats.

A novel 3-D organotypic culture model by co-culturing alpha-SMA positive CAF and cholangiocarcinoma cells in a collagen matrix

Project description:The increased M-NM-1-smooth muscle-actin positive cancer-associated fibroblastic cells (CAF) in the desmoplastic stroma may relate to a more aggressive cancer and worse survival outcomes for intrahepatic cholangiocarcinoma (ICC) patients We developed a novel 3-D organotypic culture model by co-culturing M-NM-1-SMA positive CAF and cholangiocarcinoma cells in a collagen matrix. Cholangiocarcinoma cell lines were established by isolating M-NM-1-SMA positive cancer-associated fibroblastic cells (CAF) (BDEsp-TDFE4) and cholangiocarcinoma cells (BDEsp-TDEH10) from tumors arising from bile duct inoculation of spontaneously-transformed low grade malignant rat BDE1 cholangiocytes (BDEsp cells). These tumor-derived cells lines were then grown in a rat tail type I collagen gel matrix, alone or in co-culture, and their gene expression profile were compared.

Alterations of rat liver tissue and hepatic stellate cells during ageing

Project description:Livers for tissue preparation and HSC isolation were derived from 2 and 22 months old male Wistar rats from Janvier Labs (France). Samples from three different lobes (median lobe, left lateral lobe, right lateral lobe) of each liver were collected and pooled for tissue analysis by gene expression. To isolate HSC, the livers were digested with enzyme solutions and HSC were enriched by density gradient centrifugation. HSC were purified by fluorescence-activated cell sorting using their typical retinoid fluorescence emitted after UV-light excitation. The sorted HSC were collected in IMDM supplemented with 10% FCS and 1 % antibiotic-antimycotic solution and cultured for 24 hours. Total RNA of HSC and whole liver tissue from 3 young and 3 old rats was extracted using the Qiagen RNeasy Mini Kit. RNA samples obtained from cultured HSC and whole liver tissues were sent to IMGM Laboratories (Martinsried, Germany) for gene expression analyses by microarrays (Affymetrix, GeneChip Rat Gene 2.0 ST Array, Thermo Fisher Scientific) in triplicates for each age group. The array data were processed by the Transcriptome Analysis Console 3.0 (Thermo Fisher Scientific).

Promotion of Cholangiocarcinoma Growth by Diverse Cancer-associated Fibroblast Subpopulations

Project description:Here we analyzed mouse and human samples to characterize origin, subtypes, functions and cell-cell interactions of cancer-associated fibroblasts in cholangiocarcinoma, a highly desmoplastic tumor of the liver. Hepatic stellate cell-derived cancer-associated fibroblasts were isolated from two different models of murine intrahepatic cholangiocarcinoma, induced by overexpression of YAP+AKT or KRASG12D in combination with sg-p19, and compared by bulk RNA-sequencing to hepatic stellate cells from two models of liver fibrosis, induced by bile duct ligation or DDC diet. CAF-enriched fractions of from YAP+AKT or KRAS/sg-p19-induced intrahepatic cholangiocarcinoma, were analyzed by single-cell RNA sequencing. A cell suspension from human cholangiocarcinoma, containing all cell populations, was analyzed by single cell RNA-sequencing.

Solute carrier family 12 member 5 promotes tumor development of intrahepatic cholangiocarcinoma

Project description:Intrahepatic cholangiocarcinoma (ICC) is the second most common primary malignant tumor of the liver, characterized by high malignancy, poor prognosis, and lack of effective treatment.Solute carrier family 12 member 5 (SLC12A5) is frequently overexpressed in many tumors and is involved in the development and progression of several human cancers. Here, we aimed to investigate the expression and biological function of SLC12A5 in ICC.
