Promotion of Cholangiocarcinoma Growth by Diverse Cancer-associated Fibroblast Subpopulations

ABSTRACT: 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.

Deconstruction of the immune microenvironment identifies tumor-, immune- and stroma-specific subtypes of intrahepatic cholangiocarcinoma

Project description:We have profiled by RNA-sequencing healthy livers and 4 distinct murine intrahepatic cholangiocarcinoma (iCCA) models to compare their molecular profile to the identified human STIM clusters of iCCA. Results: Comparative analysis indicated high molecular similarity between the KRAS/p19 model and the human Inflammatory stroma cluster while the other models resembled the Hepatic stem-like cluster.

Effect of YAP overexpression on HuCCT1 cholangiocarcinoma cell line transcriptome (YAP overexpression)

Project description:The YAP pathway in regulating organ size by integrating external signals to control the expression of genes involved in cell proliferation. YAP is known to be involved in tumorigenesis in several tissues, yet its role in cholangiocarcinoma is not established We used microarrays to assess the role of YAP pathway in cholangiocarcinoma either by overexpressing a constitutively active YAP1 mutant, or by downregulating YAP1 expression using shRNA HuCCT1 cells where transfected with either an empty vector or a vector overexpressing the constitutively active YAP1 S127A; cells were harvested, RNA was collected and analyzed using microarray

Integrative Transcriptomic Profiling reveals Hepatic Stem-like Phenotype and Interplay of EMT and miR-200c in Intrahepatic Cholangiocarcinoma [miRNA]

Project description:We compared transcriptomic profiles of ICC tumor specimens to hepatocellular carcinoma (HCC) specimens using Affymetrix mRNA array and the miRNA array platforms to search for unique gene signatures linked to patient prognosis. ICC and HCC share common stem-like molecular characteristics and stem-like tumor features associated with poor prognosis. Gene expression profiling of 16 intrahepatic cholangiocarcinoma (ICC), 7 mixed type of combined hepatocellular cholangiocarcinoma (CHC), 2 Hepatic adenoma, 3 focal nodular hyperplasia (FNH), 5 non-tumor liver tissues, and 2 CCA cell lines were performed.

Next-generation sequencing quantitative analysis of the transcriptome of intrahepatic cholangiocarcinoma cell line treated with or without anlotinib.

Project description:To examine the potential mechanism of anlotinib to inhibit intrahepatic cholangiocarcinoma, we used RNA-seq to analyze the effect of anlotinib treatment on the transcriptome changes of intrahepatic cholangiocarcinoma cell lines HCCC9810 and RBE. HCCC9810 and RBE cells were treated with DMSO or anlotinib at 5 μM for 24 hours, and then subjected to total RNA isolation and deep sequencing. We used Venn diagrams of RNA-seq results of HCCC9810 and RBE cells treated with anlotinib to indicate genes that were up- or down-regulated (adjusted P value <0.05, fold = 2.0). There are 420 genes in both groups (Figure 4A, 273 genes up-regulated and 147 genes down-regulated). In summary, the above sequencing results were analyzed by bioinformatics, and it was concluded that by inactivating the VEGF / PI3K / AKT signaling pathway and through cell cycle arrest, anlotinib treatment inhibited the proliferation and invasion of tumor cells and promoted Apoptosis.
