Transcription profiling of mouse control 25-dpc embryos from control vs. valproic acid (VPA) treated dams and control P19 mouse EC cells vs 1 mM sodium valproate for 24 h

ABSTRACT: Valproic acid (VPA) is a potent inducer of neural tube defects (NTDs), but its mechanism of teratogenicity is not known. To study the transcriptional response of VPA during the susceptible period, i.e. when VPA is likely to exert most of its teratogenic effect, RNA was extracted from 8.25-dpc embryos (6 h post treatment) from control and VPA-treated dams, and subjected to microarray analysis (four arrays). To be more useful for risk assessment, in vitro models, using cells, may bridge biomarkers discovered by gene expression profiling in an animal in vivo model. Since pluripotent embryocarcinoma (EC) cell lines may be relevant models for early embryonic cells, P19 mouse EC cells were treated with or without 1 mM sodium valproate for 24 h and alos subjected to microarray analysis (four arra
