Background Uninephrectomy (UNX) is performed for various reasons, including kidney cancer or donation. Kidneys being the main site of L‐arginine production in the body, we tested whether UNX mediated kidney mass reduction impacts L‐arginine metabolism and thereby nitric oxide production and blood pressure regulation in mice. Methods and Results In a first series of experiments, we observed...

Tyrosine hydroxylase catalyses the hydroxylation of L-tyrosine to l-DOPA, the rate- limiting step in the synthesis of catecholamines. Mutations in the TH gene encoding tyrosine hydroxylase are associated with the autosomal recessive disorder tyrosine hydroxylase deficiency, which manifests phenotypes varying from infantile parkinsonism and DOPA-responsive dystonia, also termed type A, to...
