ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...

Liver‐ and Immune‐Enriched Molecular Signatures Associated With Mortality in Older Adults
Untargeted plasma proteomics and metabolomics identified molecular signatures associated with all‐cause mortality in older adults. A liver‐enriched proteomic profile was associated with mortality risk in the ILAS cohort and showed consistent associations in an independent validation cohort, supporting circulating proteomic profiles for mortality risk ...

This study reveals that 5‐hydroxytryptamine (5‐HT) synapses in the spinal cord and 5‐HT neurons in the brainstem of the SOD1‐G93A amyotrophic lateral sclerosis (ALS) mouse model are significantly altered, showing a decrease in pre‐symptomatic stages but a marked increase as the disease progresses.

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.

Construction of the immune thrombocytopenia (ITP) chronicity prediction model was based on sex‐stratified multi‐omics analysis, identifying key sex‐specific predictors (intercellular adhesion molecule‐1 [ICAM‐1] and biopterin in males; actin, alpha 2, smooth muscle, aorta [ACTA‐2] and N6‐acetyl‐L‐lysine in females).

Skin Hyperpigmentation: An Under‐Recognized Dermatological Clue to Vitamin B12 Deficiency
Hyperpigmentation over the dorsal aspect of both hands, prominently involving the knuckles. ABSTRACT Cutaneous hyperpigmentation, an overlooked manifestation, can be an early sign of vitamin B12 deficiency. This case highlights symmetric pigmentation on the dorsum of hands and palms in a long‐term vegetarian.

A Novel Multimodal LC–MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF
ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

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

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),

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.
