Mutation Research-Genetic Toxicology and Environmental Mutagenesis《突变研究:遗传毒理学和环境诱变》(一年8期). Mutation Research – Genetic Toxicology and Environmental Mutagenesis (MRGTEM) publishes papers advancing knowledge in the field of genetic toxicology. Papers are welcomed in the following areas: New developments in genotoxicity testing of chemical agents (e.g. improvements in methodology of assay systems and interpretation of results). Alternatives to and refinement of the use of animals in genotoxicity testing. Nano-genotoxicology, the study of genotoxicity hazards and risks related to novel man-made nanomaterials. Studies of epigenetic changes in relation to genotoxic effects.
