Protein expression in the nucleus accumbens of rats exposed to developmental vitamin D deficiency.
<h4>Introduction</h4>Developmental vitamin D (DVD) deficiency is a candidate risk factor for schizophrenia. Animal models have confirmed that DVD deficiency is associated with a range of altered genomic, proteomic, structural and behavioural outcomes in the rat. Because the nucleus accum...
