Implementation of a large-scale ENU mutagenesis program: towards increasing the mouse mutant resource
1MRC Mammalian Genetics Unit and UK Mouse Genome Centre, Harwell, UK. p.nolan@har.mrc.ac.uk
Summary
This study details a large-scale ethylnitrosourea (ENU) mutagenesis program in mice to identify new gene mutations. The comprehensive screening approach generates valuable mutant and phenotype data for genetic research.
Area of Science:
- Genetics
- Genomics
- Developmental Biology
Background:
- Systematic mouse mutagenesis is crucial for understanding gene function.
- Previous methods lacked the scale and comprehensiveness required for genome-wide screens.
Purpose of the Study:
- To establish a large-scale ethylnitrosourea (ENU) mutagenesis program for identifying dominant mutations.
- To create a comprehensive resource of mouse mutants and associated phenotype data for the research community.
Main Methods:
- Genome-wide screening of ENU-mutagenized mice for visible defects.
- Utilizing the SHIRPA protocol for systematic phenotyping at 5 weeks.
- Assessing locomotor activity, acoustic startle response (prepulse inhibition), and clinical biochemistry.
Main Results:
- Development of a multi-stage screening pipeline for mutant mice.
- Archiving of frozen sperm and DNA samples for future genetic analysis.
- Establishment of a substantial mutant and phenotype database.
Conclusions:
- The ENU mutagenesis program provides a valuable resource for mouse and human genetics.
- This initiative will aid in improving the mouse mutant map and identifying genes underlying novel mutations.
- The generated data will facilitate gene function analysis and the discovery of new biological pathways.
