Increasing Tetrahydrobiopterin in Cardiomyocytes Adversely Affects Cardiac Redox State and Mitochondrial Function Independently of Changes in NO Production [PDF]

, 2016
Tetrahydrobiopterin (BH4) represents a potential strategy for the treatment of cardiac remodeling, fibrosis and/or diastolic dysfunction. The effects of oral treatment with BH4 (Sapropterin™ or Kuvan™) are however dose-limiting with high dose negating ...

Sacubitril/Valsartan Ameliorates Inflammation and Oxidative Stress in Hypertensive Heart Disease by Upregulating CAMKK2 Protein and Modulating the AMPK/AKT/GSK‐3β Axis

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Sacubitril/valsartan (Sac/Val) has emerged as an effective compound with myocardium‐protective functions in experimental and clinical trials for heart failure. This study investigated the function of Sac/Val in hypertensive heart disease (HHD) and explored the underlying mechanism.

Fatty aldehyde dehydrogenase, the enzyme downstream of tetrahydrobiopterin-dependent alkylglycerol monooxygenase

Pteridines, 2013
The tetrahydrobiopterin-dependent degradation of ether lipids by alkylglycerol monooxygenase (AGMO) produces fatty aldehydes, which are toxic to cells.

p38(MAPK)/p53 signalling axis mediates neuronal apoptosis in response to tetrahydrobiopterin-induced oxidative stress and glucose uptake inhibition: implication for neurodegeneration. [PDF]

, 2010
BH4 (tetrahydrobiopterin) induces neuronal demise via production of ROS (reactive oxygen species). In the present study we investigated the mechanisms of its toxicity and the redox signalling events responsible for the apoptotic commitment in SH-SY5Y ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Investigation of a potential role for aldose reductase AlrA in tetrahydropteridine synthesis in Dictyostelium discoideum Ax2

Pteridines, 2017
Dictyostelium discoideum Ax2 is well-known for the synthesis of d-threo-tetrahydrobiopterin (DH4) with a smaller amount of l-erythro-tetrahydrobiopterin (BH4).

Widespread occurrence of glyceryl ether monooxygenase activity in rat tissues detected by a novel assay

Journal of Lipid Research, 2007
An assay was set up for glyceryl ether monooxygenase activity in tissue samples using the novel substrate 1-O-pyrenedecyl-sn-glycerol and high-performance liquid chromatographic analysis of reaction mixtures with fluorescence detection, allowing robust ...

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Expression of full-length human alkylglycerol monooxygenase and fragments in Escherichia coli

Pteridines, 2013
Alkylglycerol monooxygenase (AGMO; EC 1.14.16.5) is the only enzyme known to cleave the O-alkyl ether bond of alkylglycerols in humans. It is an integral membrane protein with nine predicted transmembrane domains.
