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.

Characterization of the Protective Effect of Tetrahydrobiopterin Against S-Nitroso-N -Acetyl-D ,L-Penicillamine Induced Endothelial Cell Injury

Pteridines, 1999
The purpose of this study was to characterize the protective effect of tetrahydrobiopterin (BH4), one of the cofactors of nitric oxide (NO) synthase, against NO-induced endothelial cell injury. The addition of S-nitroso-N-acetyl-D,L-penicillamine (SNAP),

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 ...

The Sooner, the Better: Neuroprotective Strategies in Fetuses With Congenital Heart Disease

Prenatal Diagnosis, EarlyView.
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.

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.

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).

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.
