Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...

NSAID ingestion augments training‐induced muscle hypertrophy and differentially affects muscle mRNA expression, but not strength gains, in trained men

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the impact of NSAID ingestion on resistance exercise training‐induced changes in muscle morphology, function and gene networks relative to placebo ingestion in trained males. Abstract Non‐steroidal anti‐inflammatory drugs (NSAIDs) are widely overused in sports.

Gas Chromatography‐Mass Spectrometry‐Based Phytochemical Profiling and Bioactivity‐Guided Fractionation of Psidium guineense Stem Extracts: In Vitro and In Silico Insights Into Antioxidant, Antidiabetic and Antibacterial Potentials

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Psidium guineense (Myrtaceae) is traditionally used for various medicinal purposes, although its stem remains underexplored. This study provides the first integrated phytochemical, pharmacological and computational evaluation of the stem extracts to elucidate their antioxidant, antidiabetic and antibacterial potential.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Functional specialization of the yeast Rho1 GTP exchange factors [PDF]

open access: yes, 2012
Rho GTPases are regulated in complex spatiotemporal patterns that may be dependent, in part at least, on the multiplicity of their GTP exchange factors (GEFs).

MicroRNA‐Mediated Regulation of Brain Aging Hallmarks: Implications for Neurodegeneration and Neural Recovery

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
Hallmarks of brain aging regulated by microRNAs (miRNAs). This graphical abstract illustrates the central role of miRNAs in coordinating key biological processes associated with brain aging. miRNAs regulate multiple interconnected hallmarks, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis and impaired ...

Targeting the nuclear export receptor exportin‐1 in acute myeloid leukaemia: From biology to clinical translation

open access: yesClinical and Translational Medicine, Volume 16, Issue 5, May 2026.
• XPO1 hyperactivation promotes leukaemogenesis by altering nucleocytoplasmic transport and transcriptional control in acute myeloid leukaemia (AML). • Selinexor and eltanexor show preferential activity in NPM1‐mutated, DEK::NUP214‐positive and SF3B1‐mutated myeloid neoplasms.

The Acidic Domains of the Toc159 Chloroplast Preprotein Receptor Family are Instrinsically Disordered Protein Domains [PDF]

open access: yes, 2009
Background: The Toc159 family of proteins serve as receptors for chloroplast-destined preproteins. They directly bind to transit peptides, and exhibit preprotein substrate selectivity conferred by an unknown mechanism.
