英文摘要
DESCRIPTION (Adapted from investigator's abstract): The applicant proposes to
identify genes regulating early mammalian development. Progress in
understanding mechanisms of later development has been rapid due to the
conservation of gene function from Drosophila to mouse. However, gene targeting
of mouse orthologues has been much less informative about the early events of
cleavage, compaction, genesis of the extra-embryonic tissues, implantation,
axis determination, gastrulation and neural induction. New strategies are
necessary. A direct, genetic approach to identifying and characterizing early
developmental genes is proposed. Firstly, deletions covering mouse chromosome 2
will be generated. These deletions will be created in embryonic stem (ES) cells
where they will be mapped and the breakpoints cloned. The deletion chromosomes
will be established in mice. Secondly, early developmental phenotypes will be
characterized for the deletions we make, and for existing deletions of
chromosome 2. Overlapping and nested deletions will be used to map genes, which
are necessary for early development, from cleavage to neural induction. Lastly,
a balancer chromosome 2 will be constructed. The balancer chromosome will
permit efficient screening for chemically induced point mutations in the genes
defined with the deletion chromosomes.
