Untargeted Metabolomics Identifies N‐Lactoyl‐Amino Acids as Dose‐Responsive Plasma Biomarkers of Metformin Adherence in Type 2 Diabetes

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 1057-1069, April 2026.
Metformin is the most widely prescribed antidiabetic drug, yet adherence remains difficult to objectively assess. Using untargeted metabolomics and lipidomics, we analyzed plasma from 637 patients with type 2 diabetes (T2D) with confirmed metformin use and 143 nondiabetic controls, annotating 614 metabolites.

Neuronal Activity Promotes Node‐Like Cluster Assembly Prior to Myelination and Remyelination in the Central Nervous System

open access: yesGlia, Volume 74, Issue 4, April 2026.
Ronzano et al. show that neuronal activity promotes node‐like cluster (NLC) formation before (re)myelination by regulating β1Nav and Nav1.1, which are essential for NLC assembly. This may represent an intermediate step in activity‐driven myelination and contribute to the regulation of axonal conduction.

Purslane (Portulaca oleracea L.) Extract Alleviates Atherosclerosis in ApoE−/− Mice

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 7, 15 April 2026.
Oral administration of purslane extract at 400 mg/lg/day for 4 weeks reduces atherosclerotic plaque formation, endothelial dysfunction, and vascular inflammation through suppressing the MAPK pathway and activating AMPK/PI3K/Akt/eNOS pathway in ApoE−/− mice. ABSTRACT Portulaca oleracea L.

pH‐Dependent Microenvironmental Ionic Signaling in Pancreatic Ductal Adenocarcinoma

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Aim Pancreatic ductal adenocarcinoma (PDAC) develops within a uniquely dynamic pH landscape shaped by substantial acid–base fluxes produced by the exocrine pancreas. Secretion of alkaline pancreatic juice, normally linked to digestion, produces intermittent acidifications of the pancreatic interstitium, which challenges epithelial and stromal ...

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2595-2606, April 2026.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

Epigenetic Modulation of the ACE System Underlies the Slow Aerobic Muscle Phenotype and Metabolic Exercise Response

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Weekly moderate‐to‐vigorous activity (≈6 h) induced a marked increase in ACE promoter methylation in exercised knee‐extensor muscle. In combination with the ACE I/D genotype, ACE methylation contributed to ACE gene activity regulation in ways aligning with the slow‐twitch, aerobic muscle phenotype and its metabolic response to endurance exercise ...
