Impact of gut probiotic metabolites on phenylketonuria
Phenylketonuria is an unusual inherited metabolic disease induced by mutations of the phenylalanine hydroxylase gene, resulting in phenylalanine accumulation.

The interplay between genotype, metabolic state and cofactor treatment governs phenylalanine hydroxylase function and drug response [PDF]
The discovery of a pharmacological treatment for phenylketonuria (PKU) raised new questions about function and dysfunction of phenylalanine hydroxylase (PAH), the enzyme deficient in this disease.

Online electrochemistry with mass spectrometry, followed by a combination of these two techniques with capillary electrophoresis as a strong separation technique in between, is used to study the oxidation behavior of L‐tyrosine at a neutral pH value to suggest possible electrogenerated products on the surface of a carbon‐based screen‐printed electrode.

The Reaction Mechanism of Phenylalanine Hydroxylase. – A Question of Coordination
Phenylalanine hydroxylase (PAH) is a non-heme iron and tetrahydrobiopterin-dependent enzyme that catalyzes the hydroxylation of L-phenylalanine to L-tyrosine using dioxygen as additional substrate.

Dopa-responsive dystonia and hyperprolactinaemia : a novel association in two sisters [PDF]
Dopa-Responsive Dystonia (DRD) is a rare hereditary condition of childhood-onset dystonia which responds dramatically to treatment with levodopa. It was first described in 1971 as a "hereditary progressive basal ganglia disease with marked diurnal ...

Serum prolactin as a biomarker for the study of intracerebral dopamine effect in adult patients with phenylketonuria: a cross-sectional monocentric study [PDF]
BACKGROUND: It has been previously postulated that high phenylalanine (Phe) might disturb intracerebral dopamine production, which is the main regulator of prolactin secretion in the pituitary gland.

This study investigated the effects of salicylic acid (SA) application on the softening of grapes (Vitis vinifera L. ‘Red Globe’) during cold storage. The results demonstrated that SA treatment effectively delayed softening by regulating cell wall, cuticular wax, and phenylpropanoid metabolism.

Histopathological Effects on the Eye Development During Perinatal Growth of Albino Rats Maternally Treated with Experimental Phenylketonuria During Pregnancy [PDF]
Phenylketonuria (PKU) is a genetic disorder that is characterized by an inability of the body to utilize the essential amino acid, phenylalanine. The disease results from a deficiency in phenylalanine hydroxylase, the enzyme catalyzing the conversion of ...

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF
ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

Introduction: Phenylketonuria (PKU) is an error of the metabolism of the amino acids due to the gene mutation that codifies for the enzyme called phenylalanine hydroxylase (PAH). 564 cases of mutations in different exons have been reported.
