GenEvolutioN is an expert spin off, dedicated to in vitro genetic toxicology and toxicology expertise using new Human cell models. GenEvolutioN is in line with the evolution of biological and technological progress. The use of stem cells and a whole panel of new techniques is a mark-up. GenEvolutioN is the interaction between the various techniques according to industrial or clinical requirements with an adequate approach to requests in a regulated environment. GenEvolutioN is a genetic toxicology platform with different approaches and also innovative techniques. This project is the result of many years of research and aims to improve the care of patients exposed to genotoxic agents, as well as to further develop personalized medical treatment.
Telomere – centromere analysis
Innovative technology to analyze chromosome structure.
Recent publication showed implication of shorthenen Telomere size in toxicity after test article exposure. (Radhia publi).
Regarding personnalized medicine, resistance and/or to chimiotherapy treatment is showed to be related to telomere size (publi à ajouter).
You will benefit from a quick and confident technique implemented by Radhia M’Kacher and performed by our skilled team.
Preclinical and clinical safety evaluation of your test article
Combination of telomere-centromere measurement with chromosome aberration test (OECD 473).
Identification of micronucleus components when combined to in vitro micronucleus assay (OECD 487)
Medical diagnosis to adapt radiotherapy and/or chimiotherapy protocol according to telomere size
Evaluation of potential genotoxic impurities/intermediates, metabolites and batch qualification (ICH M7)
GLP and screening in vitro genetic Toxicology Studies
In vitro testing on cell line (TK6) or on human blood from donor or patients
Qualitative and quantitative approach
Test article from chemical synthesis or plant extract
We are also dedicated to perform standard genetic toxicology studies according to OECD guidelines. Our team with 25 years-experience will assist for analysis and interpretation of results.
