Zinc finger protein (ZFP) transcription factors are essential for regulation of gene expression in the developing brain. We previously reported that Pb exposure perturbed the DNA-binding of ZFP such as Sp1 and Egr-1 in the cerebellum, which play critical role in CNS development. In this study, we focused on hippocampal Sp1 DNA-binding and mRNA expression in neonatal Pb-exposed animals. The expression...
