The role of outer mitochondrial membrane proteins in Myocardial Ischemia-reperfusion Injury (MIRI) largely remains unknown. Here, the authors demonstrate that the outer mitochondrial membrane protein Myocardial Mitochondrial Antiviral Signaling (MAVS) protein promotes MIRI suggesting MAVS protein as potential therapeutic target.

Modifications enhancing degradation resistance and albumin affinity enabled the delivery of an siRNA conjugate silencing MMP13 to guinea pig and murine arthritic joints, improving therapeutic outcomes following intravenous administration.

Nicotinamide N-methyltransferase (NNMT) and its metabolite 1-MNA have been implicated in liver disease and stress adaptation. Here, the authors show that NNMT/1-MNA protects against hepatic ischemia-reperfusion injury by modulating the AKT/FOXO1/ANGPT2/JNK axis.

Mendelian randomization (MR) identifies causal relationships from observational data but has increased error rates when the genetic variants used as instruments come from a single region, a typical scenario when assessing molecular traits like protein or metabolite levels as risk factors. Here the authors introduce a single-region pleiotropy-robust MR method, validating the method on three ground truth sources, showing its capability to identify disease-causing molecular traits.

The skin has emerged as a regulator of blood pressure, but the mechanisms remain unclear. Here, the authors show that skin RAS activity, controlled by ATRAP in keratinocytes, modulates hypertension through effects on vasoconstriction and water loss.

The vertebrate brain forms during embryonic development through mechanical processes that are precisely coordinated in space and time. Here, the authors uncover how extrinsic forces regulate tissue flows and cellular rearrangements to shape the early neural plate during zebrafish gastrulation.

A population of neutrophils in the skin produces extracellular matrix, providing a defence strategy by reinforcing the barrier properties of the skin and helping to block the entry of pathogens.

PIEZO1 is critical in numerous physiological processes, but monitoring its activity and localization in cells can be challenging. Here, the authors present a chemogenetic platform to visualize endogenous human PIEZO1 localization and activity in native cellular conditions, expanding the knowledge on mechanotransduction across single cells and tissue organoids.

A method for de novo design of peptide macrocyles called RFpeptides has been developed. RFpeptides is an extension of RoseTTAFold2 and RFdiffusion and combines structure prediction and protein backbone generation for rapid and custom design of macrocyclic peptide binders.

Some cancer cells exhibit high loads of reactive iron in lysosomes, and this feature is exploited by using fentomycin-1, a newly developed small molecule, to induce ferroptosis.

Study shows PTSD predisposition shares distinct genes and genomic regions with several cardiovascular conditions. Here the findings reveal neuronal, immune, and metabolic pathways, and repurposed drug targets that further the understanding of the comorbidity.

Inflammatory monocytes in the brain meninges promote stress-induced fear behaviour, and the pathways involved can be modulated using psychedelic compounds.

Lipopolysaccharide-induced breakdown of the blood–brain barrier requires activation of GSDMD-mediated plasma membrane permeabilization and pyroptosis in brain endothelial cells.

KDM4C regulates cathepsin L-mediated histone H3 N-terminal tail clipping through grainyhead-like 2 (GRHL2) methylation in breast cancer. This link between the cellular redox state and chromatin remodeling might represent a therapeutic target in KDM4C-amplified tumors.

Cell Neural Networks on Spatial Transcriptomics (CellNEST) deciphers patterns of communication between cells in spatially resolved transcriptomics data and can detect both signals between individual cells and relay networks of communication.

GABAB receptors contribute to complex inhibition that regulates cortical neurons in a translationally relevant manner over adult life. Here, authors show stronger presynaptic inhibition in humans than rats, and a role for GABAB receptors in the anti-seizure profile of levetiracetam.

This study uncovered genetic associations with environmental sensitivity in psychiatric and neurodevelopmental traits in an international collaboration using data from more than 21,000 monozygotic twins—the largest genetic study of monozygotic twin differences to date.

Efficient hydrogen production is a major societal challenge. Here the authors use operando neutron diffraction to quantitatively support the operating principle of a memory reactor that allows super-equilibrium operation of the water–gas shift reaction, which can also be used for steam methane reforming.

BRCA1 and BRCA2 are well known breast cancer predisposition genes, however, many variants have not yet been classified for their pathogenicity. Here, the authors analyse a large combined cohort to provide evidence of variant pathogenicity.

Corti et al. show that the proteoglycan Syndecan-2 (Sdc2) regulates the interaction between phosphatase DEP1 and the vascular endothelial growth factor receptor VEGFR2. Depletion or antibody-mediated inhibition of Sdc2 causes compromised internalization of DEP1, and excessive expression of DEP1 in the membrane results in large dephosphorylation specifically of VEGFR2 Y951 residue, leading to reduced VEGF-mediated permeabilization without affecting other VEGF-mediated functions, with beneficial effects in animal models of skin edema and brain focal stroke.

JWST observations suggest that both pebbles and planetesimals played an important role in forming the giant exoplanet WASP-121 b beyond the H₂O ice line. They also indicate that strong vertical mixing likely drives the nightside atmospheric chemistry.

The ratio between the levels of two synaptic proteins in cerebrospinal fluid predicts future cognitive resilience versus decline among presymptomatic individuals and individuals with early Alzheimer’s disease harboring amyloid and tau pathology.

Wheat stem rust resistance gene Sr6-mediated resistance is enhanced at lower temperatures whereas Sr13 and Sr21 resistances are enhanced at higher temperatures. Here, the authors clone Sr6 and show the divergent molecular pathways governing temperature-dependent resistance among these genes.

There is currently no approved influenza vaccine for newborns, so development of such a vaccine is warranted. Here the authors show, using a African green monkey newborn model, that an adjuvanted nanoparticle vaccine containing the stem region of influenza hemagglutinin can induce robust IgG responses, with the functionality of the antibodies linked to viral clearance.

The core circadian transcription factor BMAL1 regulates circadian-dependent myocardial injury.

Total cell cycle duration is a key hallmark of cancer initiation, and determines whether defects in apoptosis, senescence, immune surveillance, angiogenesis, DNA repair, polarity and proliferation lead to cancer development.

Polymer–lipid–peptide nanoparticles carrying an antiplatelet antibody and a chemotherapy drug deplete tumour-associated platelets to increase vascular permeability and augment the accumulation of the drug in tumours.

Structure-function relationship of the vibrissa follicle and associated afferents are revealed by synchrotron X-ray imaging of rat vibrissae with distinct functions.

Controlled switching of the spin state of transition metal ions is key in many enzymatic reactions, but difficult to replicate in synthetic systems. Here the authors report on an iron(III) porphyrin with a photochromic axial ligand that, in solution, reversibly switches between low-spin and high-spin upon irradiation with two different wavelengths.

Using a global database of the radiocarbon content of rivers combining new and published measurements, isotopic mass balance suggests that about 60% of river CO₂ emissions are derived from millennial or older carbon sources.
