Team 08 - Biotherapies Genetics and Oncology (BioGO)

Équipe 08 – Biotherapies Génétique et Oncologie (BioGO)

The BioGO team gathers strong expertise in gene therapy, fundamental and practical aspects of genome editing, genetic-related cancer initiation and predisposition and protein and nucleic acid-derived circulating cancer biomarkers. Technically, in addition to routinely used mouse-based in vivo experimental models, the team also possesses state-of-the-art molecular and cellular tools, such as induced pluripotent stem cells (human iPSCs), CRISPR-Cas technology, high throughput gene analysis and vectorology. Our cell and gene therapy knowledge from non-cancer hereditary diseases is used to propose innovative patient management with porphyria and to create tumor genetic vulnerabilities by cancer gene therapy or with naturally occurring molecules to render tumor cells sensitive to conventional treatments. We also explore CRISPR-CAS genotoxicity, focusing on the oncologic risk, and work on CRISPR-Cas gene therapy safety. Our translational program focused on identifying constitutive mutations leading to cancer susceptibility and detecting circulating cancer elements by liquid biopsy.

Cancer liquid biopsy

Liquid biopsy is a promising tool to help therapeutic decision-making. Our research program on liquid biopsy is the result of tight interactions between the research unit and the clinicians of the team. A multimodal liquid biopsy can improve the sensitivity of pancreatic ductal adenocarcinoma (PANC-CTC, clinical trial # NCT03032913), for which we are testing the highly sensitive CRISPR-Cas tool. We are also assessing resectable tumor aggressiveness by high scale proteomic analysis. We are developing the extracellular vesicle-based liquid biopsy of rectum cancer response assessment (RECC-EV, clinical trial # NCT04852653).

Heme biosynthesis deficiency in genetic diseases and cancers: therapeutic approaches and implication in oncogenesis

Porphyrias are inherited metabolic diseases of heme biosynthesis characterized by the toxic overproduction and clearance of porphyrins and/or their precursors ALA and PBG. The team develops new concepts of therapeutic approaches based on the identification of enzymes and/or metabolic pathways that could be targeted by pharmacological molecules using high-throughput screening strategies (chemical and CRISPR lentiviral libraries). The candidates will be evaluated in new cellular models of porphyria available in the laboratory as well as in murine models of the disease. The team is also interested by the role of heme and biosynthesis in oncogenesis. Team members lead both diagnostic laboratory and clinical reference centers for porphyrias at the Bordeaux University Teaching Hospital of Bordeaux and are involved in national and international networks for heme synthesis disorders.

Genetic susceptibility of breast cancer

The Cowden’s disease shows constitutional deleterious variants of PTEN. But some patients present a Cowden-like disease without an identifiable mutation of PTEN. It is possible that intergenic variants may create susceptibility to the disease. We hypothesize that (i) the activation of the PTEN promoter may be dependent on regulatory regions distant from the gene in topologically associated chromatin domains, TAD, (ii) constitutional genetic alterations in PTEN TADs could impair PTEN expression, related to a Cowden’s disease phenotype, (iii) the removal of the regulatory cis regions by chromatin breaks with the destruction of a PTEN TAD, is a mechanism of PTEN gene downregulation. We map and functionally characterize the chromosomal locus of PTEN and neighboring gene regions, in healthy cells expressing PTEN and in a tumor model PTEN-less. Genetic alterations specifically localized in functional PTEN TADs are being identified in patients with a phenotype Cowden’s disease-like.

CRISPR-Cas9 genotoxicity: detect, understand, prevent

CRISPR-Cas9 nuclease is a very promising technology for gene therapy. The first clinical trials have started. However, genome editing, to be safe, must be precise and reliable. Genotoxicity at the targeted locus (ON-target) is little studied. Unexpectedly, we observed megabase-scale loss-of heterozygoties, following the use of Cas9 nuclease to edit the genome at the UROS (Chr10) and the globin (Chr11) loci in cell lines and primary cells. These results raise a potential new worrisome safety issue for CRISPR use in clinic. Indeed, theses undesired outcomes can lead to impact cell behavior. This nuclease side-effect was recently confirmed in human embryos. This project measures their functional impact, and reveals the molecular mechanism(s) to find solutions to secure CRISPR-Cas9 technology.

Modelling and study of pathogenic consequences of genetic alterations linked to oncogenesis

Oncogenesis is a multistep process due to cumulative molecular alterations. For certain genomic regions known to be altered in cancers, the target genes have still not been identified. Uncovering these genes and their biological functions is essential for understanding the carcinogenic process and for better cancer patients’ management. The absence of relevant cell lines carrying the genetic alterations of interest, but also the fact that, when such cell lines are available, they exhibit many other molecular alterations, is a major limitation to study the pathogenic contribution of individual genomic hits. The genetic engineering approaches that we master in our team (CRISPR-Cas9, expression and RNA interference lentiviral vectors) allow us to model alterations of genes or chromosomal regions (gene overexpression or silencing, mutations, deletions, translocations and copy neutral losses of heterozygosity). Modelling these molecular events, alone or in combination, in cellular and animal models and characterization of the molecular (epigenetic status and gene expression) and cellular consequences (proliferation, survival, clonogenicity and tumorigenicity, invasion and metastasis) allow us to study their contribution and cooperation in oncogenesis.

Tumor sensitization to treatments by gene therapy

Using our knowledge on deleterious inherited genetic disease, we target tumor cell metabolism or genetic events occurring in early oncogenesis to propose innovative therapeutics, especially cancer-specific gene therapy. One of the outcomes should be the sensitization to conventional treatments such as dynamic phototherapy and radiotherapy. For example, we want to create in vivo porphyric tumors by inducing an enzymatic deficiency in heme biosynthesis. We use genome-editing and develop oncotropic viral delivery vector.

Tumor sensitization to treatments by bioactive food components

 

Radiosensitization through bioactive food components (BFCs) is approached with orthotopic rectum and pancreatic cancer models. The radiotherapy oncologists apply gamma irradiations protocols, paralleling human management, on the XENX mouse irradiator (University of Bordeaux animal facility). The differential cytotoxic effects of potent stilbenes, including resveratrol, between healthy and tumor cells are mechanistically characterized. They help evidence new actionable tumor vulnerabilities.
