Restoration of norepinephrine and reversal of phenotypes in mice lacking dopamine beta-hydroxylase.

Abstract excerpt

Mice with a targeted disruption of the dopamine beta-hydroxylase (DBH) gene are unable to synthesize norepinephrine (NE) and epinephrine. These mice have elevated levels of dopamine in most tissues, although the levels are only a fraction of those normally found for NE. It is noteworthy that NE can be restored to normal levels in many tissues after a single injection of the synthetic amino acid precursor of NE,...
