Dr. Cornett’s research interests are focused on regulation of adrenergic receptor gene expression in the rat lung and the homeostatic roles of the neurohypophysial hormone vasotocin in the domestic chicken. Adrenergic receptors mediate the effects of epinephrine and norepinephrine. My laboratory has developed adeno-associated viral vectors that express a functional β2-adrenergic receptor. These vectors are being delivered to rat lung in order to increase β2-adrenergic receptor function in airway epithelial cells. The long term goal is to increase sensitivity of the airways to the relaxing effects of β2-adrenergic agonists. Regarding the actions of vasotocin, immunohistochemical techniques, radioimmunoassays and in situ hybridization histochemistry are being used to investigate regulation of vasotocin gene expression in the chicken hypothalamus under conditions of osmotic stress and during oviposition. We have cloned and pharmacologically characterized receptors that bind vasotocin and transduce its physiological effects in the shell gland and anterior pituitary gland.
In addition, Dr. Cornett is the Director of the Arkansas INBRE Program. The goal of the Arkansas INBRE is to expand and strengthen the biomedical research infrastructure of academic institutions in the state by developing a multidisciplinary research network united by the scientific theme of Cellular Signaling, Growth, and Differentiation.
