摘要
This present invention provides rapid, reproducible, biomarker-based screening methods for the developmental toxicity testing of compounds. The methods are designed to identify the exposure level at which a test compound perturbs metabolism in a manner predictive of developmental toxicity. In particular, the perturbation of two metabolites, ornithine and cystine, is measured, wherein a ratio of the fold change in ornithine to the fold change in cystine of less than or equal to about 0.88 is indicative of the teratogenicity of a test compound.
