- The retinoic acid-inducible transcription factor
AP-2 is expressed in epithelial and neural crest cell
lineages during murine development. AP-2 can regulate
neural and epithelial gene transcription, and is
associated with overexpression of c-erbB-2 in human
breast-cancer cell lines. To ascertain the importance
of AP-2 for normal development, we have derived mice
containing a homozygous disruption of the AP-2 gene.
These AP-2-null mice have multiple congenital defects
and die at birth. In particular, the AP-2 knockout
mice exhibit anencephaly, craniofacial defects and
thoraco-abdominoschisis. Skeletal defects occur in the
head and trunk region, where many bones are deformed
or absent. Analysis of these mice earlier in
embryogenesis indicates a failure of cranial
neural-tube closure and defects in cranial ganglia
development. We have shown that AP-2 is a fundamental
regulator of mammalian craniofacial development.
