Age-Dependent Variation in Blood Biopterin Peaks Following Oral Tetrahydrobiopterin Administration in Phenylketonuria. [PDF]

open access: yesJ Inherit Metab Dis
ABSTRACT The correct diagnosis of tetrahydrobiopterin (BH4, sapropterin dihydrochloride)‐responsive phenylketonuria (PKU) and treatment with BH4 are important for prognosis and quality of life. We examined whether age affects biopterin bioavailability following oral BH4 administration in PKU and whether this influences BH4 responsiveness.

The Sooner, the Better: Neuroprotective Strategies in Fetuses With Congenital Heart Disease. [PDF]

open access: yesPrenat Diagn
ABSTRACT Congenital heart disease (CHD) is the most frequent congenital malformation at birth and is associated with neurodevelopmental impairments. Alterations in cardiovascular physiology can lead to reduced cerebral blood perfusion and oxygenation, which negatively affects brain growth and maturation.

Tetrahydrobiopterin in biomedical research [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2009
Tetrahydrobiopterin (BH4) is an endogenously synthesized cofactor, required for various enzyme activities and for some less well-defined functions. It is also required at the cellular level. The known enzymes that depend on BH4 are phenylalanine hydroxylase (PAH), tyrosine hydroxylase, tryptophan hydroxylases 1 and 2, all three types of nitric oxide ...

A Comparison of Sepiapterin and Tetrahydrobiopterin Uptake by BRL2H3 Cells

open access: yesPteridines, 1996
Cellular uptake of sepiapterin and tetrahydrobiopterin was compared quantitatively with RBL2H3 cells in culture. RBL2H3 is a mast cell line and has the ability to synthesize serotonin.

Examining the role of insulin in the regulation of cardiovascular health [PDF]

open access: yes, 2013
A substantial body of evidence has reported that insulin has direct actions on the cardiovascular system independent of its systemic effects on plasma glucose or lipids.

The International Working Group on Neurotransmitter related Disorders (iNTD): A worldwide research project focused on primary and secondary neurotransmitter disorders [PDF]

open access: yes, 2016
INTRODUCTION: Neurotransmitters are chemical messengers that enable communication between the neurons in the synaptic cleft. Inborn errors of neurotransmitter biosynthesis, breakdown and transport are a group of very rare neurometabolic diseases ...

Tetrahydrobiopterin in antenatal brain hypoxia-ischemia-induced motor impairments and cerebral palsy

open access: yesRedox Biology, 2017
Antenatal brain hypoxia-ischemia, which occurs in cerebral palsy, is considered a significant cause of motor impairments in children. The mechanisms by which antenatal hypoxia-ischemia causes brain injury and motor deficits still need to be elucidated ...

Tetrahydrobiopterin attenuates ischemia-reperfusion injury following organ transplantation by targeting the nitric oxide synthase: investigations in an animal model

open access: yesPteridines, 2013
Ischemia-reperfusion injury is a primarily non-allospecific event leading to the depletion of the essential nitric oxide synthase cofactor and potent antioxidant tetrahydrobiopterin.
