A new compact comet assay for versatile genotoxicity testing and environmental monitoring



The ComPack project is a French-Norwegian1 collaborative research and innovation project that addresses the need for reliable and validated testing for industry and academia to assess the effect of chemicals on human health and the environment. The public-private consortium plans to develop by the end of 2016 a high throughput, automated, versatile, validated and user-friendly DNA testing facility based on the innovative modified comet assay.
The comet assay is the most widely used method for measuring DNA damage in eukaryotic cells. This test system is used for environmental agents as well as in human biomonitoring, for endogenous damage and antioxidant resistance analysis and DNA repair. The comet assay is employed by the pharmaceutical, cosmetic and chemical industries for screening novel drugs and chemicals for genotoxicity. The genotoxicity testing market is rapidly growing and is expected to reach €3,210 million in 20182, 50% of which is currently represented by the cosmetics and personal-care industry and 32% by the pharmaceutical segment.

Standard procedures for genotoxicity testing have been laid down by, among other organisations, the European Food Safety Authority (EFSA) and the International Committee for Harmonisation (ICH).
OECD guidelines are in preparation for the comet assay in in vivo genotoxicity testing, with the advantage that it can be applied to virtually all tissues. JACVAM (Japanese Committee for the Validation of Alternative Methods), in association with the corresponding European committee, ECVAM, is carrying out validation trials for the in vitro assay. REACH regulations (Registration, Evaluation, Authorisation and Restriction of Chemical substances) stipulate that chemicals whose usage per annum exceeds a certain level must be registered with details of toxicity for humans and possible environmental impact. As such, the comet assay is mentioned by REACH as a suitable assay for in vitro tests.

A new plant-based comet assay to complement and strengthen conventional techniques
The comet assay is also a potentially powerful ecological research tool for assessing DNA damage and repair in sentinel animals such as mussels, eathworms or mice and plants in the environment. However, despite their fundamental roles in every ecosystem, plants have not been much used in these studies. There is therefore a need to develop an alternative, fast, cost-efficient, reliable and more informative plant-based assay. The project aims to increase several-fold the capacity and versatility of the comet assay, by adapting high troughput approaches for different cell types and for plants, incorporating enzymes with a range of lesion specificities.

The Human Hepatic cell line HepaRG™ used for the new comet assay
Many chemicals are genotoxic only after activation. HepaRG™ is a well-known human hepatic cell line commercially available through Biopredic International, which, unusually, can differentiate into fully functional hepatocytes. These are particularly useful in genotoxicity testing, as they retain xenobiotic metabolizing (phase I and phase II) enzymes and so can activate many potential carcinogens, unlike most permanent cell lines. Adapting the cells for use in the new comet assay will require the advanced cell culture skills of the French CRO Eurosafe, together with comet assay experience.

All partners part of the project have proven expertise in relevant technological development to cover together the whole range of project needs. Overall, the Compack project will help chemical, nanomaterials, cosmetic, pharmaceutical and food industries and CROs by delivering them all components for a more versatile, high throughput and fully automated comet assay for better safety of all chemicals, drugs, cosmetics and foods exposure of human and the environment.

What is the Comet assay?

Comet_AssayThe comet assay is a sensitive and versatile method for detecting DNA damage in eukaryotic cells. Alkaline electrophoresis of agarose-embedded, lysed cells (nucleoids) produces comet-like images, with broken DNA loops comprising the tail; the relative intensity of the tail indicates the frequency of DNA breaks.

Biopredic International to expand applications of HepaRG™ hepatic cells with a new partner in Singapore



Singapore, November 25th, 2014
InvitroCue has obtained a worldwide non-exclusive sublicense for the HepaRG™-RP progenitor cells from Biopredic International. The sublicense includes the production and sales of mature HepaRG™-RP cells in vials and in combination with InvitroCue’s cell culture models, namely 3D CelluSponge and HepatoCue. InvitroCue will also offer in vitro DMPK and in vitro toxicology services using mature HepaRG™-RP cells.
Biopredic International holds exclusive, unrestricted worldwide rights for the HepaRG™ cells which was developed by the French National Institute of Health and Medical Research (INSERM). According to Biopredic International, HepaRG™ is one of the most interesting and useful hepatic cell lines discovered to date. It is derived from a human hepatocellular carcinoma and features the full array of functions, responses and regulatory pathways of primary human hepatocytes. The HepaRG™-RP cells have not undergone transfection or gene modifications and retain many characteristics of human hepatocytes. This enables their use in versatile applications, such as in vitro ADME or hepatotoxicity screening and mechanistic toxicology testing. HepaRG™ is a unique and well established hepatic stem cell line as demonstrated in more than 200 publications to date.
“We are very excited to offer the HepaRG™-RP cells together with our 3D cell culture models to our customers. It allows us to combine the advantages of HepaRG™-RP cells over other hepatic cell lines with the advantages of our 3D cell culture models to get better predictive data for human drug metabolism and toxicology, ” said Dr Michael McMillian, Head of Scientific and Regulatory Affairs at InvitroCue with more than two decades of experience in drug testing and toxicology.
“Biopredic International has extensive experience in producing consistent HepaRG™ cell source. We are delighted to announce this partnership. It will significantly benefit InvitroCue's customers and strengthen our product and service offerings using primary human hepatocytes for ADMET applications,” said Dr Steven Fang, Founder and Managing Director of InvitroCue.
Christophe Chesne, CEO of Biopredic International comments: “Biopredic International is pleased to have a new partner on board to develop new applications relying on the HepaRG™-RP cells besides the well-known CYP induction protocol, and to promote the cells. InvitroCue will receive from Biopredic the new HepaRGTM-RP cell line, reprogrammed (RP). These cells are derived from the HepaRG™ parental line after reprogramming them to a stem cell status (protected via another patent in the HepaRG™ IP portfolio) and then redirecting after epigenetic manipulation towards the hepatic lineage. The HepaRGT™-RP cells display a phenotype very similar to the parent HepaRG™ but with better stability over multiple passages with modified culture media.”

HepaRG™ used for a new micronucleus assay


Real time in vitro evaluation of the carcinogenic potential of contaminants

The Genotrace project, combining targeted research and technology transfer1, aims at delivering an innovative test to improve the safety of chemical products, drugs, human and animal food and the environment. The project consortium is led by INRA (French National Institute for Agricultural Research) and includes CNRS (French National Center for Scientific Research), the University Toulouse III – Paul Sabatier and the company Biopredic International. 
The Genotrace project has just received the support of the French National Research Agency (ANR) for three years. 

Among the current short-term assays developed to assess DNA damage induced by a physical or chemical agent, the micronucleus assay (MN) represents a reliable and precise method that is already validated as a regulatory test in a battery of predictive tests for carcinogenesis. The Genotrace project aims at bringing major technological innovations to develop a new MN assay, that will allow to monitor both dynamically and in real time the production of chromosome damages and the signal of a genotoxic reporter on HepaRG® cells (HepaRG® cells can metabolize chemical compounds, this metabolization step is required for many carcinogenic compounds).

A new test for real time monitoring

The new test developed within the Genotrace project will rely on fluorescent biotracers recently generated by the academic partners (INRA, CNRS, University Toulouse III - Paul Sabatier). The first biotracer will allow visualizing the chromatin (the DNA filament associated to proteins, forming the chromosomes), without cellular toxic effect, thus allowing the dynamic monitoring of the cellular chromatin in real time. Second, the expression of a specific gene will allow the evaluation of any associated activation of the DNA damage pathway. Therefore the test will provide information on the micronuclei origin, whether induced by mechanisms of DNA breaks (clastogenic) or produced through the abnormal chromosomes distribution during mitosis (aneugenic). To take into account the metabolism of many chemical compounds, these biotracers will be stably expressed in the HepaRG® cells, human liver cells that are metabolically active, optimized for the MN test by BIOPREDIC International.

The developed in vitro MN assay will be adapted to a medium- to high throughput straightforward readable assay, thanks to the implementation of high content screening imaging protocols and the development of an image analysis and classification-based pipeline. The assay will bring new capacities to the classic MN assay and may lead to breakthroughs in the prevention and/or the diagnosis of exposure to genotoxicants present in the environment, food or future drug candidates.

The innovative genotoxicity test developed by the Genotrace stakeholders will be able to answer today’s recommendations, with significant improvements in the scientific, technical and economical fields. Overall, the Genotrace project aims to a better safety of all chemicals, drugs, and foods exposure of human, farm animals/pets and environment.

What is the micronucleus assay?
As the name suggests, the MN test is based on the presence of DNA breaks visible as small pieces after coloring. Two mechanisms contribute to the formation of micronuclei: a break of chromosome or a defect in the chromosome distribution, at the end of the cell division stage. This test is performed either on cells, generally lymphocytes from an animal or a human exposed to genotoxic products or on cells cultured in vitro. Whilst the assessment of disruptions in vivo cannot be foreseen, the MN test, in its in vitro version, does not enable a real time evaluation of the disruptions that will lead to the formation of micronuclei, and thus prevents the identification of the mechanism causing the chromosome fragments.
