Our missions

Our mission is to develop basic genomic approaches based on human tumors analyses to identify new mechanisms of tumorigenesis and to transfer this knowledge into biomarkers and therapeutic targets that could be introduced in clinical care. In particular, we aim to identify new genomic alterations and mechanisms of carcinogenesis. We also aim to identify new risk factors and genetic predispositions promoting the development of tumors. Our general strategy is based on the omic’s analyses of large cohorts of patients with liver tumors (benign and malignant), mesothelioma and clear cell renal carcinoma. The group was pioneer in the elucidation of the molecular classification of benign and malignant liver tumors. Then we perform (1) functional validation using cell and animal models and (2) we translate our findings into the clinics to improve surveillance, diagnosis, prognosis, treatment and follow-up of the patients.

Our task forces

The team include a total of 39 peoples  organized in 5 groups with their founded projects:

• “Functional Genomics of Liver tumors” led by Jessica Zucman-Rossi focusing on the characterization of genomic alterations in benign and malignant liver tumors, functional validation, identification of new risk factors and genetic predisposition and translation to the clinics.

FunGeST Projects

We aim to develop scientific projects with specific objectives to integrate innovative tumor genomic characterizations with metabolism and immune response to identify new biomarkers and therapeutic targets useful for the patients. To this aim, we focus on 3 major types of cancer: liver, mesothelioma and renal carcinoma, in close collaboration with clinicians and pathologists. Thanks to our future moving at the Centre de Recherche des Cordeliers our team will benefit from close collaborations with other teams involved in Onco-Immunology, Metabolism and developing innovative genomic approaches.

Role of viral infection and integration in liver carcinogenesis

Collaborators: S Imbeaud (IR), C Peneau (PhD st), T La Bella (PhD st), J Zucman-Rossi (PUPH);

Involvement of pathogen agents in human carcinogenesis remain to be investigated. Our recent identification of AAV2 as the fourth virus involved in insertional mutagenesis prompt us to develop a project to evaluate consequences of HBV, HCV and AAV infections in liver tumorigenesis by integrating the analysis of viral and tumor genome alterations. Our aim is to reconstruct the natural history of the viruses (genome variation, replication, structural alterations, selection…) in the context of tumor cell selection in patients putatively treated by antiviral therapies or exposed to multiple pathogens. We will also search for additional pathogens in WGS data and collaborate with the international ICGC viruses project.

New molecular subtypes and cancer driver genes in pediatric liver tumors

Collaborators: G Morcrette (PhD st), E Letouzé (CR Inserm), J Pilet (PhD st), S Imbeaud (IR), G Couchy (IE, PhD st), Julien Calderaro (pathologist), JC Nault (MCUPH), J Zucman-Rossi (PUPH); in cooperation with SIOPEL,

Most of pediatric liver neoplasms are poorly analyszed at the genomic and molecular level. They include hepatocellular carcinomas (HCC), fibrolamellar carcinomas (FLC), hepatoblastomas (HB), transitional liver cell tumors (TLCT) and also benign neoplasms, hepatocellular adenomas (HCA) and focal nodular hyperplasias (FNH). We aim to perform an integrated genomic analysis of these pediatric hepatocellular tumors to better understand their mechanism of tumorigenesis. To this purpose, we have collected a series of 193 patients with pediatric frozen liver tumors part of the national HEPATOBIO tumor resource. Within this series, 48 cases/67 frozen tumor samples have been selected for whole genome sequencing (WGS) and RNA sequencing (RNAseq) within the GEPELIN project funded by France Génomique for the WGS part. Our specific aims are to (1) identify putative driver genes altered in pediatric tumors and validate them functionally (2) perform new transcriptomic classification to derive new altered pathways and diagnostic/prognostic markers, (3) characterize the mutational and chromosome rearrangement signatures to identify new mechanism of carcinogenesis (4) search for therapeutic targets. These results will be compared with the adult liver tumors data that we have accumulated in the lab.

Innovative genomic data integration to decipher the interaction between risk factors, endogeneous cellular processes and genomic alterations in liver carcinogenesis

Collaborators: E Letouzé , J Shinde , S Imbeaud (IR), L Meunier (PhD st), Q Bayard (M2), T Hirsch (Post-doc), J Zucman-Rossi (PUPH

In the last 5 years, we have generated large genomic data sets including 350 tumors analyzed by whole exome sequencing, 270 by RNA-seq, 250 by methylation arrays and 100 by whole genome sequencing. We will use this exceptional resource to unravel key questions in the natural history of liver cancers. (1) What mutational processes drive tumorigenesis? We have so far identified 10 point-mutation signatures associated with known (aflatoxin B1, tobacco) or unknown mutagenic processes in liver cancers. We will extend these analyses to signatures of indels and structural rearrangements, and perform a meta-analysis of all published liver cancer data sets to unravel the association of signatures with risk factors and predisposing variants. (2) What are the missing drivers in liver cancers? Analysis of coding mutations by us and others revealed tens of driver genes and pathways but 30% of tumors still have no identified driver event. In order to identify non-coding driver alterations, we will use whole genome and RNA-seq data to systematicallly screen for mutations and structural rearrangements modifying regulatory regions, chromatin context and 3’ UTR sequences and affecting mRNA expression and stability. (3) How to the genomic, epigenomic and transcriptional layers interact in tumor cells? We will develop innovative strategies to unravel the connexions between genomic alterations, DNA methylation and gene expression profiles. (4) What is the timing of genomic alterations along tumorigenesis? We and others have developed statistical approaches to time mutational signatures, copy-number alterations and driver events in the life history of a cancer using intra-tumor heterogeneity. We will conduct an ambitious project to analyze the evolution of genomic, transcriptional and micro-environment features in 25 patients with multiple samples along the treatment.

Genetic predisposition to benign and malignant liver tumors

E Letouzé (CR Inserm), P Nahon (PUPH), E Trepo (Post-doc), J Yang (Ph st), JC Nault (MCUPH), Zucman-Rossi (PUPH)

Candidate gene studies have uncovered a limited number of variants reproducibly linked to hepatocellular carcinoma (HCC). The HECAM project aims to identify newgermline variants predisposing to HCC in the French population and to test their ability to modify patient care in clinical practice. Therefore, a genome-wide association study will be performed in a multicenter cohort of chronic liver disease patients with (n = 2,066) and without (n = 2,666) HCC using the Illumina Infinium Global Screening Array including ~ 660,000 markers). Validation of the top variants will be performed in two French replication cohorts of cirrhotic patients included in HCC surveillance programs (n = 2,249). The performance for HCC risk stratification will be finally assessed through integration of genetic information into specific algorithm-based prediction models. An original integrative approach including somatic information already generated will be used for prioritizing variants impacting liver carcinogenesis. Finally, genotype-phenotype associations will be performed to build prognostic models. We also plan to analyze benign liver tumors to search for genetic predisposition to the development of hepatocellular adenoma in a cohort of 500 patients with in parallel an epidemiological study.
