title: Gene-teratogen interactions in chemically induced congenital malformations.
abstract: Exposure of the embryo to environmental chemicals can result in congenital malformations or abortion. Although experimental teratology data are considered sufficient for risk assessment, only knowledge of their mechanisms of action permits a justifiable extrapolation of animal data to humans. Mechanistic studies of some teratogenic agents such as retinoic acids, valproic acid, diethylstilbestrol, and cyclopamine provided evidence of interference with regulation of genes controlling the embryonic development. The new genomic technologies are important tools in this field and may represent a real improvement in understanding the mechanisms of action of chemical teratogens.
