Atrial natriuretic peptides: the role of phenylalanine on biological activity.

abstract：:The hypothalamic-pituitary-adrenal axis adapts to periods of chronic or repeated stress. We have now investigated whether there is any differential effect of repeated immobilization stress on CRH and arginine vasopressin (AVP) gene transcription in the hypothalamic paraventricular nucleus (PVN), using probes for both ...
