Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

Abstract In human health risk assessment of chemicals and pharmaceuticals, identification of genotoxicity hazard usually starts with a standard battery of in vitro genotoxicity tests, which is needed to cover all genotoxicity endpoints. The individual tests included in the battery are not designed to pick up all endpoints.

Abstract As a part of the International Workshop on Genotoxicity Testing (IWGT) in 2022, a workgroup was formed to evaluate the level of validation and regulatory acceptance of transcriptomic biomarkers that identify genotoxic substances. Several such biomarkers have been developed using various molecular techniques and computational approaches. Within

Abstract Gene expression biomarkers have the potential to identify genotoxic and non‐genotoxic carcinogens, providing opportunities for integrated testing and reducing animal use. In August 2022, an International Workshops on Genotoxicity Testing (IWGT) workshop was held to critically review current methods to identify genotoxicants using ...

Review of Transcriptomic Biomarkers That Predict In Vitro Genotoxicity in Human Cell Lines
ABSTRACT The current genotoxicity testing paradigm provides little mechanistic information, has poor specificity in predicting carcinogenicity in humans, and is not suited to assessing a large number of chemicals. Genomic technologies enable the characterization of genome‐wide transcriptional changes in response to chemical treatments that can inform ...

Critical Evaluation of Methods for the Identification of Aneugens
ABSTRACT The genotoxic potential of chemicals must be evaluated in regulatory safety assessment settings, including but not limited to, the development of new pharmaceuticals, industrial chemicals, food and cosmetic ingredients, and agrochemicals. Initial assessment of the chromosome‐damaging potential of chemicals is often conducted in mammalian cells
