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.

Metabolomic and lipidomic signatures of Helicobacter pylori infection: Unveiling biochemical pathways associated with neurodegeneration

open access: yesiMetaOmics, EarlyView.
Our study employed an integrated lipidomics and metabolomics approach to elucidate Helicobacter pylori‐driven metabolic perturbations along the gut–brain axis. H. pylori infection was established in gastric epithelial (AGS) cells, and the resulting conditioned media (secretome) was collected and exposed to neuronal (IMR‐32) cells.

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),

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

open access: yesCancer Science, Volume 117, Issue 3, Page 683-694, March 2026.
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 ...

Metabolomic Analysis of Phytophthora parasitica Growth in the Presence of β‐sitosterol Indicates Adaptive Mechanisms Modulated by Sterols

open access: yesJournal of Basic Microbiology, Volume 66, Issue 2, February 2026.
ABSTRACT Phytophthora parasitica is a generalist phytopathogenic oomycete that infects a series of crops with great economic interest, including tomato, tobacco, and citrus species. Sterols are essential lipids in eukaryotic organisms, playing a fundamental role in the structure and function of the cell membrane.

Enhanced Monacolin K Production in Monascus purpureus Via Mutagenesis and Nitrogen Source Optimization

open access: yesJournal of Basic Microbiology, Volume 66, Issue 2, February 2026.
ABSTRACT Monascus fungi are valued for their production of Monacolin K (MK), a bioactive compound with recognized lipid‐lowering and multifunctional properties. To enhance MK yield in solid‐state fermentation, this study combined atmospheric and room‐temperature plasma (ARTP) mutagenesis with L‐arginine supplementation.

Tetrahydrobiopterin Responsive Hyperphenylalaninemia without Biopterin Deficiency

open access: yespteridines, 2000
Hyperphenylalaninemia (HPA) results from a deficiency of the enzyme phenylalanine hydroxylase (PAH) or of its cofactor, tetrahydrobiopterin (BH4). In 1999, Kure et al reported that some patients with PAH deficiency showed lowering of blood Phe levels after BH4 loading (1). We found several patients with HPA whose serum phenylalanine levels decreased at

Further Insights Into Anticholinergic Action Informed by Japanese Anticholinergic Risk Scale

open access: yesGeriatrics &Gerontology International, Volume 26, Issue 1, January 2026.
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 ‐

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 ...
