Optimal N-ethyl-N-nitrosourea (ENU) doses for inbred mouse strains.
ENU is a powerful germline mutagen in the mouse, providing the opportunity to analyze the functions of large numbers of genes in the mammalian genome. In many mutagenesis experiments, it would be beneficial to exploit the advantages of inbred mouse strains. To perform an effective ENU mutagenesis screen using inbred mice, a dosage regimen is required to determine the optimal dose of ENU for that inbred strain, a time-consuming preliminary process. We have carried out dosage regimens for mutagenizing doses of ENU in ten inbred strains of mouse: 129X1/SvJ, 129S6/SvEv, A/J, BALB/cJ, BTBR/N, C3He/J, C3HeB/FeJ, C57BL/6J, C57BR/cdJ, and CBA/CaJ, and determined an optimal dose for each strain, defined by length of sterile period and number of males to survive treatment. Three strains: A/J, BALB/cJ and C57BL/6J, are able to tolerate high doses, up to 300 mg/kg body weight, and are highly recommended for mutagenesis studies.
期刊介绍：
As of January 2000, Developmental Genetics was renamed and relaunched as genesis: The Journal of Genetics and Development, with a new scope and Editorial Board. The journal focuses on work that addresses the genetics of development and the fundamental mechanisms of embryological processes in animals and plants. With increased awareness of the interplay between genetics and evolutionary change, particularly during developmental processes, we encourage submission of manuscripts from all ecological niches. The expanded numbers of genomes for which sequencing is being completed will facilitate genetic and genomic examination of developmental issues, even if the model system does not fit the “classical genetic” mold. Therefore, we encourage submission of manuscripts from all species. Other areas of particular interest include: 1) the roles of epigenetics, microRNAs and environment on developmental processes; 2) genome-wide studies; 3) novel imaging techniques for the study of gene expression and cellular function; 4) comparative genetics and genomics and 5) animal models of human genetic and developmental disorders.
genesis presents reviews, full research articles, short research letters, and state-of-the-art technology reports that promote an understanding of the function of genes and the roles they play in complex developmental processes.
