Adenoviral gene transfer in bovine adrenomedullary and murine pheochromocytoma cells: potential clinical and therapeutic relevance.

Recombinant adenoviruses (rAd) have been widely used as gene transfer vectors both in the laboratory and in human clinical trials. In the present study, we investigated the effects of adenoviral-mediated gene transfer in primary bovine adrenal chromaffin cells (BACC) and a murine pheochromocytoma cell line (MPC). Cells were infected with one of three nonreplicating E1/E3-deleted (E1(-)/E3(-)) rAd vectors: Ad.

Urocortin 3 modulates the neuroendocrine stress response and is regulated in rat amygdala and hypothalamus by stress and glucocorticoids.

The endogenous corticotropin-releasing factor (CRF) type 2 receptor (CRFR2)-selective ligand urocortin 3 is expressed in discrete subcortical brain regions with fibers distributed mainly to hypothalamic and limbic structures. Close anatomical association between major urocortin 3 terminal fields and CRFR2 in hypothalamus, lateral septum, and medial amygdala (MEA) suggest it is well placed to modulate behavioral and hormonal responses to stress. Urocortin 3 was administered intracerebroventricularly to male rats under basal conditions or before a restraint stress, and circulating ACTH, corticosterone, glucose, and insulin were measured.
