Identification of cholangiocarcinoma-like gene expression traits in hepatocellular carcinoma

ABSTRACT: We performed gene expression profiling of hepatocellular carcinoma (HCC), cholangiocarcinoma (CC), and mixed type of combined HCC and CC (CHC). In comparison of the profiles, a novel class of HCC expressing CC-like traits was identified. Gene expression profiling of 70 hepatocellular carcinoma (HCC), 13 cholangiocarcinoma (CC), and 7 mixed type of combined HCC and CC (CHC) were performed.

<h4>Purpose</h4>The poor prognosis of hepatocellular carcinoma (HCC) is, in part, due to the high rate of recurrence even after "curative resection" of tumors. Therefore, it is axiomatic that the development of an effective prognostic prediction model for HCC recurrence after surgery would, at minimum, help to identify in advance those who would most benefit from the treatment, and at best, provide new therapeutic strategies for patients with a high risk of early recurrence.<h4>Experimental desi ...[more]

Transcription profiling by array of human Intrahepatic Cholangiocarcinoma (ICC) and Combined Hepatocellular Cholangiocarcinoma (CHC) tumors

Project description:We compared transcriptomic profiles of 23 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 HCC and ICC (CHC), 2 Hepatic Adenoma, 5 Focal Nodular Hyperplasia, and 7 Non-Tumor Tissues were performed.

Single-cell and Spatial Architecture of Primary Liver Cancer

Project description:Using single-cell RNA sequencing, spatial transcriptomic and bulk multi-omics, we elaborated a molecular architecture of 3 PLC types, namely hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular-cholangiocarcinoma (CHC) from a high-resolution perspective.

Transcriptomic profiling of the intermediate cell carcinoma of the primary liver cancer

Project description:Introduction: Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a mixed-type tumor of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA), which is classified into classical type (i.e., c-CHC) and intermediate cell type (i.e., i-CHC). c-CHC harbors both HCC and iCCA cells, whereas i-CHC is comprised of intermediate cell types lacking classical regions of HCC or iCCA cells. Notwithstanding the unique pathological feature of i-CHC, its molecular characteristics is not fully elucidated yet. Methods: To obtain molecular insights on the i-CHC, RNA-sequencing (RNA-Seq) and whole genome sequencing (WGS) profiling were performed on the tissues of i-CHC, HCC, and iCCA, respectively. Results: i-CHC showed unique transcriptomic features differing from HCC and iCCA, showing higher expression of Notch signaling and frequent splicing events of intron-retention (IR). Noticeably, we found that i-CHC had DNA-copy number loss and concomitant transcriptional suppression of METTL16, which may contribute to the aggressive progression of i-CHC via Notch activation. Conclusions: We suggest that i-CHC had unique transcriptomic features, providing new insights into the pathobiology of i-CHC.

Patient-derived organoid cultures model human primary liver cancer in vitro

Project description:The study of human liver cancer has been hampered by the lack of reliable models that faithfully recapitulate the physiopathology of the patient’s original tumour ex vivo. Here, we describe the first culture system to allow the establishment and long-term expansion of human primary liver cancer (PLC) organoids (called tumoroids) from the three most common PLC subtypes: Hepatocellular carcinoma (HCC), Cholangiocarcinoma (CC) and mixed HCC/CC tumours (CHC). We evaluated whether tumoroid lines maintain the expression profile and the genomic landscape of the original tumor they derived from by performing genome-wide (RNAseq/WES) analyses before and after culture. These analyses reveal that the cultures closely recapitulate the gene expression and the mutational landscape of the original tumor, allowing discrimination between different tumor subtypes (HCC, CHC, CC).

Fibrous stromal component in hepatocellular carcinoma reveals a cholangiocarcinoma-like gene expression trait and epithelial-mesenchymal transition.

Project description:Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are the major primary liver cancers in adults. It has been shown the phenotypic overlap between HCC and CC, comprising continuous liver cancer spectrum. As a proof of concept, a recent study has demonstrated a genomic subtype of HCC expressing CC-like gene expression trait, i.e. CC-like HCC, which has revealed common genomic trait of stem cell-like property and aggressive clinical outcome. However, the histopathological characteristics of these intermediate phenotype was not fully evaluated yet. Here, we found that a variant HCC with fibrous stromal component, i.e. scirrhous HCC, has CC-like genomic features. By performing gene expression profiling and immunohistochemical evaluation, we compared the morphological and molecular features of scirrhous HCC with CC and classical HCC. We found that the scirrhous HCC express both CC-like and stem cell-like expression traits. In addition, we observed the expression of core epithelial-mesenchymal transition (EMT)-related genes, which may contribute to the aggressive behavior of scirrhous HCC. Over-expression of transforming growth factor Î² (TGF-Î²) signaling was also found, implying its regulatory role in the pathobiology of scirrhous HCC. Conclusion: We suggest that the fibrous stromal component in HCC may contribute to the acquisition of CC-like gene expression trait in HCC. The expression of stem cell-like trait and TGF-Î²/EMT molecules may play pivotal roles in the aggressive phenotype of scirrhous HCC Gene expression profiles of HCC, CC and HCC with fibrous stroma were compared.

Effect of FENDRR on genetic expressions of primary liver cancer based on next generation sequencing

Project description:Primary liver cancer (PLC) is the third largest contributor to cancer mortality in the world. PLC is a heterogeneous disease that encompasses several biologically distinct subtypes including hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular-cholangiocarcinoma (CHC). The cells were cultured in DMEM medium supplemented with 10% fetal bovine serum and 1% antibiotic-antimitotic solution. The HCC cell line LM3 and ICCA cell line RBE were transfected using Lipofectamine 3000 reagent following the manufacturer’s protocol and incubated for 48h for further analysis. The gene expression profiles were analyzed of LM3 and RBE cells transfected with si-FENDRR or si-NC to assess effect of FENDRR on genetic expressions of PLC.

Mixed hepatocellular – cholangiocarcinoma derives from liver progenitor cells and depends on senescence and IL6 trans-signaling, bulk RNA sequencing

Project description:Mixed hepatocellular – cholangiocarcinoma (HCC-CCA) is a highly malignant primary liver cancer of increasing incidence for which the cell of origin and molecular pathogenesis have not yet been fully elucidated. Here, by linking YFP to the progenitor cell specific promoter of Foxl1 in Mdr2-KO mice, we generated a lineage tracing mouse model for liver cancer to monitor the development of mixed HCC-CCA tumors following a prolonged period of liver inflammation. In this model of chronic hepatitis, we demonstrate that liver progenitor cells are the source of mixed HCC-CCA tumors but not of hepatocellular carcinoma (HCC). Moreover, we show that IL6, originating from senescent hepatic cells, is involved in progenitor cell proliferation and development of mixed HCC-CCA tumors via IL6 trans-signaling. These findings could form the basis for the development of novel therapeutic approaches for treatment of mixed HCC-CCA liver cancer.
