Gene Expression Profiling during Pregnancy in Rat Brain Tissue.

ABSTRACT: The neurophysiological changes that occur during pregnancy in the female mammal have led to the coining of the phrases "expectant brain" and "maternal brain". Although much is known of the hormonal changes during pregnancy, alterations in neurotransmitter gene expression have not been well-studied. We examined gene expression in the ventromedial nucleus of the hypothalamus (VMH) during pregnancy based on the fact that this nucleus not only modulates the physiological changes that occur during pregnancy but is also involved in the development of maternal behavior. This study was designed to identify genes that are differentially expressed between mid- and late-pregnancy in order to determine which genes may be associated with the onset and display of maternal behavior and the development of
