Section on Neural Gene Expression
Welcome. The Section on Neural Gene Expression investigates the roles and regulation of expression of vasopressin and oxytocin in the central nervous system. They are 9 amino acid peptide hormones that participate in the regulation of fluid balance, parturition and lactation. In addition, they have important roles in various behaviors, including aggression, social memory and parental care, through their actions mediated by at least 3 brain receptors. A schematic of their genes is shown below.
Our group uses a variety of techniques ranging from anatomical (hybridization histochemistry and receptor autoradiography) to molecular biological to transgenic animals to explore the functions of oxytocin and vasopressin. For example, we have generated mice lacking functional oxytocin, as well as mice that express green fluorescent protein in oxytocin neurons, in our attempts to determine the essential and non-essential roles of this hormone. We created vasopressin 1b receptor knockout mice that show a marked reduction in aggression and a modest decline in social recognition. We have recently begun studying the first conditional knockout of one of these receptors - the oxytocin receptor. Reduction of the receptor in the forebrain of mice resutls in decreased fear conditioning and deficits in intra-strain, but not inter-strain, social recognition. Our various studies with transgenic, including knockout mice, are listed here
We hope that you find the information we present on our website, including protocols and publications, informative and useful.
A Postdoctoral Fellowship in the Section on Neural Gene Expression is being offered beginning Summer, 2014.
