Targeting biliary cancer desmoplasia in culture

ABSTRACT: To more closely reproduce key cellular and stromal features of the desmoplastic reaction of cholangiocarcinoma in vitro, we developed a novel 3-dimensional culture modeling of cancer and stromal cells as a strategy for targeted therapies Cellular, molecular, and functional characterization of different cancer-associated fibroblastic (CAF) and cholangiocarcinoma cell strains isolated from orthotopic tumors arising from bile duct inoculation of spontaneously-transformed rat cholangiocytes (BDEsp cells) in Fischer 344 young adult male 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.

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.

Differentially expressed miRNAs in xenografts and organoids derived from human cholangiocarcinoma [miRNA]

Project description: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 organoids (passage 7).

Proteome comparison of a new human cholangiocarcinoma 3D co-culture tumor model to 3D single cultures.

Project description:Cholangiocarcinomas (CCA) are characterized by their desmoplastic and hypervascularized tumor microenvironment (TME) which is mainly composed of tumor cells and cancer-associated fibroblasts (CAFs). CAFs play a pivotal role in tumor progression, angiogenesis, metastasis and the development of therapy resistance. To our knowledge, no continuous human in vivo-like co-culture model is available for research. Therefore, we aimed to establish a new model that mimics the desmoplastic environment typically seen in CCA. Proteomic data comparing the new CCA tumor cell line with our co-culture tumor model (CCTM) indicated a higher correlation of the CCTM with physiological CCA characteristics according to literature. A pro-angiogenic TME that is typically observed in CCA could also be simulated in the CCTM group. Further analysis of secreted proteins revealed CAFs to be the main source for these angiogenic factors. Our CCTM represents a new, reproducible and easy-to-handle 3D CCA model for preclinical studies focusing on CCA-stromal crosstalk, tumor angiogenesis and invasion, the immunosuppressive microenvironment and the involvement of CAFs in the way that drug resistance develops.

Tumor progression in cholangiocarcinoma

Project description:Purpose: The aim of this study is to investigate mechanisms driving tumor-promoting mechanisms in cholangiocarcinoma while focusing on transitions from normal cholangiocytes to precancer lesions and from precancer lesion to invasive carcinoma. An original mouse model of intrahepatic cholangiocarcinoma was developed, based on induction of a KrasG12D mutation in cholangiocytes combined with chronic inflammation. RNA-Seq analyses compare the transcriptome of ductular proliferations, intraductal papillary neoplasm of the bile duct and intrahepatic cholangiocarcinoma. A gene cascade involving EGF, KrasG12D, Sox17 and Tns4 was identified to promote tumor progression.
