ENU mutagenesis in the mouse: application to human genetic disease.
Genetic approaches in model organisms provide a powerful means by which to examine the biological basis of human diseases as well as the physiological processes that are affected by them. Although not without its drawbacks, the mouse has become the mammalian species of choice in studying the molecular basis of disease. Targeted mutagenesis approaches in the mouse have led to dramatic increases in our understanding of human disease processes. As a complement to these gene-driven studies, three developments have led to the reassessment of a phenotype-driven approach in the mouse--the accumulation of information that has emerged from human and mouse genome sequencing projects, the use of high-efficiency point mutagens such as N-ethyl-N-nitrosourea (ENU) and the application of systematic hierarchical screening protocols for the mouse. In this paper, progress with existing phenotypic screening programmes is discussed and opportunities for the development of new mouse disease models are presented.
