Biopterin in Parkinson's disease. [PDF]

open access: yesJournal of Neurology, Neurosurgery & Psychiatry, 1987
Tetrahydrobiopterin is an essential co-factor in the natural synthesis of dopamine. Oral tetrahydrobiopterin was given in small doses to four patients with early Parkinson's disease but had no discernible effect.

Hippo Pathway Drives Durable Non‐Cell‐Autonomous Ferroptosis Resistance in Lung Cancer

open access: yesCancer Science, EarlyView.
YAP/TAZ, key effectors in lung cancer progression, paradoxically sensitize tumor cells to ferroptosis. This study reveals that YAP/TAZ‐low cells confer non‐cell‐autonomous, GCH1‐mediated durable ferroptosis resistance to neighboring YAP/TAZ‐high cells via a soluble factor, highlighting a Hippo pathway‐linked mechanism of tumor adaptation and survival ...

Cardiomyocyte tetrahydrobiopterin synthesis regulates fatty acid metabolism and susceptibility to ischaemia-reperfusion injury [PDF]

open access: yes, 2023
New Findings What is the central question of this study? What are the physiological roles of cardiomyocyte-derived tetrahydrobiopterin (BH4) in cardiac metabolism and stress response? What is the main finding and its importance? Cardiomyocyte BH4 has

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

open access: yesThe FEBS Journal, EarlyView.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale

open access: yesGeriatrics &Gerontology International, EarlyView.
ABSTRACT The increased anticholinergic burden caused by medications in older adults is one of the adverse drug reactions of particular concern, as it can exacerbate the onset of geriatric syndromes or induce cognitive dysfunction, and is also related to the issue of polypharmacy.

Genome‐Wide Protein Interaction Analysis in Parasitic Gyrodactylus Flatworms–Fish Hosts System and Drug Target Identification

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
Genomic data offer a powerful tool for studying the molecular interactions between parasites and their hosts, but they remain scarce for parasitic monogenean flatworms. This study presents the first high‐quality phased genome assembly for monogeneans (Gyrodactylus kobayashii), and uses it to predict key interacting proteins between monogenean parasite ‐

Nitric oxide and hydrogen sulfide: the gasotransmitter paradigm of the vascular system. [PDF]

open access: yes, 2017
There are several reviews on NO and hydrogen sulfide (H2 S) and their role in vascular diseases in the current relevant literature. The aim of this review is to discuss, within the limits of present knowledge, the interconnection between these two ...

Consensus Guideline for the Diagnosis and Treatment of Tyrosine Hydroxylase (TH) Deficiency

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Tyrosine hydroxylase (TH) catalyses the rate‐limiting step in dopamine biosynthesis. Autosomal recessive tyrosine hydroxylase deficiency (THD) leads to clinical phenotypes reflecting the deficiency of dopamine, norepinephrine, or epinephrine in the central nervous system (CNS), presenting along a continuous spectrum from mild to severe forms ...

First Synthesis of a Representative, Natural Pterin Glycoside: 2’-O-(α-D-Glucopyranosyl)biopterin [PDF]

open access: yes, 2009
Glycosylation of N(2)-(N,N-dimethylaminomethylene)-1’-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl) ethyl]biopterin (14) with the novel donor 4,6-di-O-acetyl-2,3-di-O-(4-methoxybenzyl)-α-D-glucopyranosyl bromide (19) in the presence of silver triflate and ...
