Overview

This week’s papers cluster around a shared translational theme: improving how therapies are delivered, targeted, and monitored by using mechanistic biology and better measurement. In oncology and immunology, multiple studies show that “response brakes” are often metabolic or microenvironmental—e.g., lactate-driven lactylation dampening STING signaling, lactylation reprogramming macrophage metabolism to suppress CD8+ T cells, and spatially distinct EMT invasion niches in HPV+ vs HPV− head and neck cancers. Complementing this, work on DNA repair dependencies (TBK1-driven HR suppression; Polθ/MMEJ defects in SMARCB1-loss tumors) and druggable transcriptional metabolic programs (EZH2–SREBP2–p300 cholesterol biosynthesis) points to more precise combination strategies and biomarkers.

A second dominant thread is “precision phenotyping” across diseases using AI, omics, and structured clinical frameworks. Examples include ML signatures for sarcopenia in type 2 diabetes muscle, AI models for ICU delirium prediction with explainability, and CT-based quantitative approaches for progressive ILD risk stratification. In Alzheimer’s disease, blood-based biomarker strategies (plasma p-tau217 with Aβ42) and highly sensitive tau-seed detection (PMCA) emphasize moving toward less invasive, earlier, and more scalable diagnosis/monitoring. In parallel, geriatrics and aging research highlights actionable risk pathways—frailty transitions and depression predicting dementia, and tissue “aging clocks” derived from histopathology—while clinical implementation/consensus papers stress that timing and operational feasibility (e.g., early CGA, asparaginase delivery) can be as important as the intervention itself.

Finally, several studies broaden the therapeutic toolkit beyond drugs alone: CNS-targeting lipid nanoparticles for mRNA across the BBB, engineered astrocyte/circuit concepts for future brain modulation, implantable sonothermal materials for localized heating, and synthetic microbial communities as controllable microbiome therapeutics. Together, these findings suggest a field-wide shift toward integrating delivery engineering, mechanistic checkpoints, and robust risk stratification to make interventions safer, more effective, and easier to deploy in real-world care.


CNS drug delivery across the blood–brain barrier

Fusion of IgG antibodies to albumin inhibits transport across the placenta.

This study tested whether fusing IgG to albumin can reduce neonatal Fc receptor (FcRn)-mediated placental transport of IgG during pregnancy using mouse models and an ex vivo human placental perfusion system. IgG–albumin fusion markedly inhibited transplacental transport in both systems while preserving FcRn-dependent prolonged plasma half-life. The findings support albumin-fusion as a strategy to improve antibody safety and efficacy during pregnancy by limiting fetal exposure.

Overcoming the blood-brain barrier using central nervous system-accessing lipid nanoparticles for enhanced mRNA therapeutics.

The study designed and tested CNS-accessing lipid nanoparticles (CA LNPs) formulated with ionizable lipids to deliver messenger RNA (mRNA) across the blood-brain barrier in wild-type mice, Ai14 reporter mice, and nonhuman primates. The lead CA2d LNP candidate enabled efficient intravenous mRNA delivery into multiple CNS cell types, including neurons, microglia, and astrocytes. This provides a translational platform for improving brain delivery of mRNA therapeutics for CNS diseases by overcoming BBB transport limits.

Neurodegeneration & Alzheimer’s disease biomarkers/therapeutics

Restoration of Neuronal Metabolism and Memory in Alzheimer’s Disease by Reprogramming the Exosomal microRNA Network.

This study explored whether reprogramming the exosomal microRNA network can restore neuronal metabolism and memory in Alzheimer’s disease (AD). By targeting exosomal microRNA dysregulation, the approach aimed to correct metabolic and synaptic dysfunction underlying AD rather than focusing only on amyloid-β plaques and tau tangles. If validated experimentally, this exosomal microRNA reprogramming strategy could provide a mechanistically grounded therapeutic avenue for metabolic synaptic disorders in AD.

Comparison of double-blind and open-label decline rates in lecanemab and donanemab trials in Alzheimer’s disease.

This study compared simulated decline trajectories from phase 3 Alzheimer’s disease trials of the anti-amyloid monoclonal antibodies lecanemab and donanemab, contrasting double-blind trial decline with open-label extension (OLE) patterns using mixed-effects models calibrated to Clarity-AD and TRAILBLAZER-ALZ 2 data. The key finding was that the apparent magnitude of benefit in open-label comparisons differed from what would be expected under double-blind conditions, highlighting how historical untreated-cohort comparisons can be influenced by selection and attrition bias. Scientifically, it clarifies how trial design and comparator choice affect inferred long-term efficacy for lecanemab and donanemab.

Cross-Sectional and Longitudinal Diagnostic Performance of Plasma p-tau217 and p-tau217/Aβ42 in Alzheimer’s Disease.

This study assessed cross-sectional and longitudinal diagnostic performance of plasma phosphorylated tau (p-tau217) alone and combined with plasma Aβ42 against Aβ-PET positivity in 326 participants from the Alzheimer’s Disease Neuroimaging Initiative and 357 Chinese older adults from the Greater-Bay-Area Healthy Aging Brain Study. The combined plasma p-tau217/Aβ42 approach showed improved concordance/diagnostic accuracy relative to p-tau217 alone across cross-sectional and longitudinal evaluations. Clinically, this supports using blood-based p-tau217 and Aβ42 to better track Alzheimer’s disease pathology and potentially streamline diagnosis and monitoring.

Amplification of seeding-competent tau aggregates by PMCA in human and experimental tauopathies.

This experimental study used protein misfolding cyclic amplification (PMCA) to amplify seeding-competent tau aggregates derived from brains of transgenic mice and human patients with tauopathies. PMCA efficiently amplified tau aggregates using complex substrates such as brain homogenates or cell lysates expressing aggregation-prone mutant tau. The work strengthens the scientific basis for PMCA as a highly sensitive assay for detecting trace misfolded tau seeds across tauopathies, with potential translational value for diagnostics and mechanistic studies.

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures.

The study investigated how Alzheimer’s disease genetic risk affects synaptic mechanisms in rat primary neuronal cultures and human neuronal cultures by downregulating PLCG2 (phospholipase C gamma 2). It found that PLCG2 downregulation disrupts dendritic morphology and synaptic function and increases amyloid-β (Aβ) levels and Tau phosphorylation in human neuronal cultures, with very rare PLCG2 loss-of-function variants (including R953*) associated with ~10-fold increased AD risk. This supports PLCG2 as a causal AD risk gene and highlights PLCG2/PLCγ2–dependent synaptic maintenance as a potential therapeutic target.

The future of blood-based biomarkers in liver cancer.

The article reviewed the current state and future prospects of blood-based (liquid) biomarkers in liver cancer, focusing on applications such as risk stratification, surveillance, early detection, and treatment monitoring. It concluded that while some cell-free DNA–based detection of actionable alterations has entered clinical practice, most candidate liquid biomarkers still lack prospective clinical validation and require translational evaluation embedded in clinical trials and prospective cohorts. This frames the key evidence gap—prospective validation—for advancing liquid biopsy into routine liver cancer care.

Neuroinflammation & neuroimmune regulation

Brain perivascular macrophages regulate endothelial cell function via a cMAF-dependent transcriptional program in mouse and human.

This study investigated how brain perivascular macrophages regulate endothelial cell function in mouse and human, focusing on the transcription factor cMAF, using single-cell multi-omics and in vivo conditional cMAF deletion. cMAF was identified as a key regulator that drives an IGF1 expression program in perivascular macrophages, enabling macrophage–endothelial communication and maintaining cerebral artery transcriptional and vascular function. These findings position cMAF–IGF1 signaling as a mechanistic target for preserving or restoring neurovascular function in health and disease.

Brain engineering & astrocyte/neuronal circuit tools

Astrocyte engineering.

This review studied the concept of “astrocyte engineering,” proposing engineered molecular access, sensing, and effector modules in astrocytes to interrogate or modify brain states. It summarizes how astrocyte interface biology can be converted into engineering logic using genetic access and signaling perturbation approaches. The scientific significance is that it provides a framework for designing targeted astrocyte-based tools for research and potentially for brain repair and modulation.

An octopamine-glutamate cotransmitting neuron gates aggressive escalation through layered inhibition in Drosophila.

This study used Drosophila melanogaster neural circuit approaches to define how an octopamine–glutamate cotransmitting neuron (Ventral paired medial 4, VPM4) controls aggressive escalation through layered inhibition. It found that VPM4 drives escalation gating via its downstream GABAergic target MBON-11, with octopamine and glutamate release independently regulated by presynaptic OAα2R and mGluR receptors. The work provides a transmitter-specific synaptic mechanism for how inhibitory circuitry constrains high-intensity aggression.

Stroke & ischemic brain injury resolution

Extracellular CIRP Dysregulates Microglial Efferocytosis in Acute Ischemic Stroke via the TLR4/miR-155/MafB Axis.

This study examined the role of extracellular cold-inducible RNA-binding protein (eCIRP) in microglial efferocytosis during acute ischemic stroke using a transient middle cerebral artery occlusion (tMCAO) mouse model. In tMCAO, eCIRP was released into cerebrospinal fluid and microglial MerTK efferocytic receptor expression decreased, while CIRP deficiency improved efferocytosis and reduced neuroinflammation via a TLR4/miR-155/MafB regulatory axis. These findings link eCIRP–TLR4 signaling to impaired microglial clearance of dying cells and suggest that targeting this axis could promote resolution of inflammation after ischemic stroke.

DWI-Positive Lesions in Patients With Acute Intracerebral Hemorrhage: Associations With Cerebral Small Vessel Disease and Clinical Outcome.

This prospective cohort study investigated diffusion-weighted imaging (DWI)-positive lesions in acute intracerebral hemorrhage (ICH) and their associations with cerebral small vessel disease (cSVD) features and 6-month functional outcome measured by modified Rankin Scale (mRS). The key finding is the characterization of prevalence and anatomical distribution of DWI-positive lesions and their clinical-radiologic and prognostic associations, with specific results truncated in the provided abstract. These data support DWI-positive lesions as potential imaging biomarkers for cSVD burden and outcome prediction after ICH.

Cancer immunotherapy & innate immune signaling (STING/IFN)

Lactate-Induced K370 Lactylation of STING Inhibits STING-TBK1 Signaling and Dampens Anti-Tumor Immunity.

This work investigated how tumor metabolism regulates innate immune signaling by studying lactate-driven post-translational modification of STING in the context of anti-tumor immunity. The authors found that lactate induces K370 lactylation on STING, which weakens STING–TBK1 interaction and shifts ubiquitination toward K48-linked chains (reducing K63-linked ubiquitination), thereby limiting STING stability/oligomerization and dampening pathway activation. This identifies STING K370 lactylation as a metabolic checkpoint that could explain resistance to STING-targeted therapies and suggests lactylation/ubiquitination modulation as a strategy to restore anti-tumor immunity.

Calibration of CAR signaling promotes asymmetric cell division to direct CAR-T cell fate and antitumor potency.

This study investigated how antigen engagement and CAR signaling strength regulate asymmetric cell division (ACD) in chimeric antigen receptor (CAR)-T cells, using engineered CAR-T systems to track fate outcomes. Antigen engagement induced ACD through polarized inheritance of the CAR immune synapse (CARIS), generating CARhigh progeny with a short-lived effector-like state and CARlow progeny with memory-like features, with CAR signaling strength acting as a tunable determinant of this bifurcation. The work supports calibrating CAR signaling to bias CAR-T fate toward persistence and improved antitumor potency, informing safer and more effective CAR-T design.

DNA hypomethylation identifying clinical benefit subgroup of small-cell lung cancer: multi-omics analysis of a phase II trial with durvalumab plus olaparib as maintenance therapy.

This multi-omics analysis of a multicenter, single-arm phase II trial tested durvalumab plus olaparib maintenance in extensive-stage small-cell lung cancer (ES-SCLC) and used DNA hypomethylation to identify a clinical benefit subgroup. The key finding is that specific DNA hypomethylation patterns stratified patients into groups with differential clinical benefit during maintenance therapy. If validated, this provides a biomarker strategy to personalize durvalumab–olaparib maintenance and improve outcomes in ES-SCLC.

Selective decay of interferon mRNAs controls antiviral immunity and innate memory.

This mechanistic study investigated how interferon (IFN) mRNAs are kept low at baseline and rapidly normalized after stimulation. The authors found that tristetraprolin (TTP), together with mRNA decay machinery, selectively promotes post-transcriptional decay of type I and type III IFN mRNAs, and loss of this pathway increases poly(A) tail length, stability, and translation leading to elevated IFN expression. This provides a molecular explanation for homeostatic control of IFN signaling and how innate memory-like responses are regulated.

A dendritic cell autophagy-neutrophil axis limits intratumoral STING immunotherapy.

This study investigated mechanisms limiting intratumoral STING agonist efficacy by using a mouse intratumoral delivery system that loads cyclic GMP-AMP (cGAMP) into virus-like particles (VLPs) to preferentially activate STING in dendritic cells, with mechanistic analyses of the resulting type I interferon signaling and T-cell priming. The work identifies a dendritic cell autophagy–neutrophil axis that constrains effective intratumoral STING immunotherapy. Clinically, defining this inhibitory circuit suggests combination approaches that relieve the autophagy/neutrophil brake to enhance responses to intratumoral STING agonists.

Cancer cell-intrinsic DNA repair & genome maintenance

Liver regeneration CRISPR screen identifies E3 ligase NEURL1B regulates hepatocyte mitosis by destabilizing microtubule organizing centers.

This study used an in vivo CRISPRi screen in regenerating mouse liver to identify genes required for hepatocyte proliferation and focused on the E3 ligase NEURL1B. The key finding is that NEURL1B regulates hepatocyte mitosis during liver regeneration by destabilizing microtubule organizing centers, helping hepatocytes manage supernumerary centrosomes and mitotic errors. Scientifically, this links a specific ubiquitin ligase to centrosome/microtubule control in regeneration, suggesting NEURL1B as a mechanistic lever for improving regenerative outcomes.

Defective microhomology-mediated end joining in SMARCB1-deficient tumors.

This study analyzed DNA repair pathway dependencies in rhabdoid tumors driven by biallelic SMARCB1 loss, identifying a defect in microhomology-mediated end joining (MMEJ) and the role of DNA polymerase theta (Polθ/encoded by POLQ). SMARCB1-deficient tumors showed reduced Polθ protein maintenance via impaired nuclear export of POLQ mRNA, and loss of MMEJ triggered compensatory hyper-dependence on the Fanconi anemia (FA)/BRCA pathway. The findings suggest that targeting FA/BRCA signaling could be a therapeutic vulnerability in SMARCB1-deficient cancers.

Inflammatory kinase TBK1 suppresses homologous recombination DNA repair to sensitize tumors to chemotherapy.

The study examined how inflammatory kinase TBK1 (TANK-binding kinase 1) affects homologous recombination (HR) DNA repair and thereby modulates sensitivity to chemotherapy in cancer cells. TBK1 activation increased chemotherapeutic efficacy by promoting DNA damage and impairing HR repair, independently of canonical inflammatory cytokine signaling as shown in IRF3- and p65-double deficient cells. This identifies TBK1 as a mechanistic lever to sensitize tumors to chemotherapy through DNA repair suppression.

Cancer metabolism & lactylation/ferroptosis/polyamine pathways

Regulation and roles of mammalian mitophagy.

This review summarized current understanding of mammalian mitophagy, focusing on regulatory pathways that either depend on PINK1 and the E3 ubiquitin ligase Parkin (encoded by PRKN/PKRN) or proceed via PINK1/Parkin-independent mechanisms. It highlights that recessive mutations in PINK1 and PRKN cause early-onset Parkinson’s disease and have been instrumental in defining mitophagy biology. Scientifically, the synthesis clarifies how multiple mitophagy routes maintain mitochondrial integrity and suggests why defects can drive neurodegeneration.

An EZH2-SREBP2 axis promotes cholesterol biosynthesis and represents a noncanonical vulnerability in tumorigenesis.

The study examined whether an EZH2–SREBP2 signaling axis regulates cholesterol biosynthesis and tumor growth, focusing on EZH2’s noncanonical transcriptional function. It found that EZH2 associates with SREBP2 to drive high expression of mevalonate pathway genes via p300-dependent transcriptional activation, enhancing cholesterol biosynthesis and sustaining tumorigenesis, and that PROTACs can target this EZH2 function as a vulnerability. This identifies a druggable metabolic dependency in cancer driven by the EZH2–SREBP2–p300 transcriptional program.

YY1 lactylation mediates epithelial barrier dysfunction during acute lung injury.

This study investigated whether YY1 lactylation drives epithelial barrier dysfunction during acute lung injury (ALI) using ARDS patient samples and multiple ALI mouse models, with mechanistic perturbations including glycolysis inhibition and lactate manipulation. Inhibition of glycolysis with 2-deoxy-D-glucose (2-DG) reduced lactate-driven injury and improved alveolar epithelial barrier function, while exogenous lactate worsened barrier dysfunction, and genetic silencing experiments implicated YY1 lactylation as a mediator. These results support YY1 lactylation as a mechanistic link between lactate accumulation and barrier failure, suggesting lactate/YY1-pathway targeting as a potential therapeutic strategy in ALI/ARDS.

AARS1-mediated lactylation reprograms macrophage lipid metabolism to restrict antitumor immunity.

This study examined how AARS1-mediated lactylation reprograms macrophage lipid metabolism to suppress antitumor immunity in hepatocellular carcinoma (HCC), focusing on the immune cell population responsible for lactylation-driven immunosuppression. The key finding is that lactylation rewires macrophage metabolic programs via AARS1 to impair CD8+ T cell-mediated antitumor responses, thereby promoting immune evasion in HCC. These mechanistic insights identify AARS1/lactylation-linked macrophage metabolism as a potential target to restore antitumor immunity.

The GCN5L2-SIX1 complex drives glycolysis to promote progression of triple-negative breast cancer.

This study investigated how the GCN5L2-SIX1 axis drives lactylation-dependent glycolysis to promote progression of triple-negative breast cancer (TNBC), using molecular interaction and functional assays in TNBC cells. The key finding is that GCN5L2 physically interacts with SIX1, regulates SIX1 lactylation, promotes glucose uptake and glycolysis, and that GCN5L2 knockdown suppresses TNBC growth/migration and increases sensitivity to paclitaxel, with SIX1 overexpression reversing these effects. These results identify GCN5L2-mediated SIX1 lactylation as a metabolic vulnerability and potential therapeutic target in TNBC.

Polyamines buffer labile iron to suppress ferroptosis.

This study examined how polyamines influence ferroptosis susceptibility in mammalian cells, using a genome-wide CRISPR screen to probe genetic interactions with the ferroptosis suppressor GPX4. Polyamines were found to buffer labile redox-active iron and polyamine depletion created a synthetic lethal dependency with GPX4, linking polyamine metabolism to ferroptosis control. The work suggests that modulating polyamine–iron homeostasis could be a strategy to tune ferroptosis sensitivity therapeutically.

Cancer microenvironment, EMT, and spatial tumor architecture

Multi-Omics Integration Identifies a CDH3-Associated Malignant Epithelial State and Immunosuppressive Niche to Predict Prognosis in Thymic Epithelial Tumors.

This study integrated single-cell RNA sequencing, spatial transcriptomics, multiplex immunofluorescence, bulk transcriptomics, functional assays, xenografts, and computational pathology to define malignant epithelial states and immunosuppressive niches in thymic epithelial tumors (TETs). It identified a CDH3-associated malignant epithelial state at the origin of malignant-state trajectories, enriched for stem-like and EMT features, with CDH3+ tumor cells preferentially localized in immunosuppressive spatial niches. Clinically, this CDH3-associated state and niche organization improved prognosis prediction, providing a potential biomarker and microenvironmental target for stratifying and treating TETs.

Spatial analysis of head and neck cancer identifies two ecosystems with distinct modes of epithelial-to-mesenchymal transition.

The study mapped tumor architecture and epithelial-to-mesenchymal transition (p-EMT) programs across HPV-positive and HPV-negative head and neck squamous cell carcinoma (HNSCC) using spatial transcriptomics (n=26). It identified two spatial ecosystems: a p-EMT edge driven by fibroblast–TGFβ coupling and a p-EMT core where immunosuppressive macrophages and neutrophils induce p-EMT via oncostatin M. These findings link microenvironmental cell states to distinct EMT spatial programs, suggesting more precise therapeutic targeting of TGFβ- versus oncostatin M–mediated invasion niches.

Cancer targeted therapy & druggable molecular vulnerabilities

Identifying independent causal cell types for human diseases and risk variants.

This computational genomics study introduced cell-type fine-mapping methods (CT-FM and CT-FM-SNP) to identify independent causal cell-type sets and causal variants for complex traits using GWAS data and candidate regulatory element (cRE) annotations. Applying CT-FM to 63 GWASs with 924 cRE annotations inferred 79 independent cell-type sets explaining ~39% of trait SNP heritability and revealed traits with multiple independent cellular mechanisms (including height, schizophrenia, and autoimmune diseases). These methods can refine mechanistic interpretation of GWAS signals by pinpointing which cell types independently drive disease risk.

Mechanism and plasticity of primitive pyroptosis.

This study functionally characterized “primitive” gasdermin (GSDM) variants from bacteria and fungi—bGSDM from Runella zeae and fGSDM/HET-Q1 from Podospora anserina—to understand mechanisms and plasticity of pyroptosis-like pore formation. It showed that these primitive GSDM homologs can form cytotoxic pores, with biochemical properties distinct from the canonical modern protease-activated GSDM pathway. These insights broaden understanding of how pore-forming executioners evolved and how pyroptosis mechanisms can vary across life.

Ligand-tuned extracellular domain dynamics are correlated with signaling states in an adhesion GPCR.

This study used single-molecule FRET (smFRET) and intracellular signaling assays to determine how ligand engagement tunes extracellular domain (ECR) dynamics of the adhesion GPCR ADGRG6 (GPR126) and correlates with signaling states. It revealed that the ADGRG6 ECR transitions among three conformational states and that locking the ECR in the closed conformation traps the receptor and alters signaling output. These findings connect partner-driven ECR conformational dynamics to functional signaling states in an adhesion GPCR, informing how extracellular cues regulate receptor activity.

Survival Benefit of ARSI Therapy in Japanese mCSPC: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis evaluated whether adding a second-generation androgen receptor signaling inhibitor (ARSI) to androgen deprivation therapy (ADT) improves overall survival in Japanese patients with metastatic castration-sensitive prostate cancer (mCSPC), comparing ARSI+ADT against conventional hormonal therapy used in Japan (ADT alone or combined androgen blockade). The key finding was that ARSI-based therapy conferred a survival benefit in the Japanese treatment context, indicating that the OS advantage seen in Western ADT-based trials also applies when the comparator is conventional Japanese hormonal regimens. This supports broader clinical adoption of ARSI+ADT for Japanese mCSPC patients and helps reconcile differences in historical standard-of-care between regions.

Association between opioid use and treatment discontinuation in patients receiving nivolumab: a real-world database study.

This retrospective real-world database study examined whether baseline opioid use is associated with time to treatment discontinuation (TTD) in patients receiving nivolumab monotherapy for non-small cell lung, gastric, colorectal, or renal cell carcinoma. Using the JMDC database (2015–2020; follow-up through 2022) and multivariable Cox models with propensity score matching and landmark analyses, it evaluated the relationship between pre-index opioid prescriptions and subsequent nivolumab discontinuation risk. The findings are clinically relevant because they may identify opioid use as a prognostic or confounding factor affecting immunotherapy persistence in routine practice.

Comparative effectiveness of ofatumumab and ocrelizumab in relapsing multiple sclerosis: a target trial emulation using multinational registry data.

This study compared the real-world effectiveness of anti-CD20 therapies ofatumumab versus ocrelizumab in adults with relapsing-remitting multiple sclerosis (RRMS) using a target trial emulation with multinational registry data from MSBase and the Observatoire Français de la Sclérose en Plaques (Jan 2021–Dec 2024). Patients initiating ofatumumab or ocrelizumab were propensity-score matched 1:1, and the primary outcomes were annualised relapse rate (ARR) and time to first relapse. If confirmed in the full results, these findings will inform comparative effectiveness and treatment selection between two widely used anti-CD20 agents in routine RRMS care.

Adjuvant oxaliplatin with S-1 (SOX) versus S-1 for stage II-III gastric cancer (CAPITAL): A randomized, open-label, phase 3 trial.

This randomized phase 3 trial studied adjuvant oxaliplatin plus S-1 (SOX) versus S-1 alone in patients with resected stage II–III gastric or gastroesophageal junction adenocarcinoma after D2 gastrectomy (CAPITAL; NCT01795027). The key finding reported in the abstract is the trial’s comparative efficacy and safety assessment with overall survival as the primary endpoint, with results truncated in the provided text. If SOX improves overall survival over S-1 alone, it would refine standard adjuvant therapy for D2-resected stage II–III gastric/GEJ cancer.

The SF3b complex in cancer: structural basis, molecular mechanisms, and therapeutic opportunities.

This review analyzed the SF3b (splicing factor 3b) complex in cancer, integrating structural insights from cryo-electron microscopy with genetic and functional evidence for how SF3b dysregulation drives aberrant alternative splicing. It highlights structural plasticity of SF3b (open–closed conformational transitions) that stabilizes pre-mRNA substrates and emphasizes therapeutic opportunities arising from recurrent SF3b core mutations and splicing vulnerabilities. The synthesis supports SF3b as both a mechanistic driver of oncogenic splicing and a potential drug target.

ELTS Score and Early “Warning” Define a Two-Stage Risk Framework for Failure-Free Survival in Chronic-Phase CML.

This pooled analysis studied predictors of failure-free survival (FFS) in chronic-phase chronic myeloid leukemia (CP-CML) in 710 newly diagnosed patients from the JALSG CML212 and New TARGET prospective studies, incorporating the ELN 2025 “Warning” category into FFS event definitions. The key finding is that the ELTS score and an early “warning” two-stage risk framework better characterizes transitions to an unfavorable state and predicts treatment failure in the tyrosine kinase inhibitor (TKI) era. This could improve early risk stratification and guide monitoring or treatment adjustments for CP-CML patients.

HSP27 regulates force-coordinated DDR1 condensate disassembly and liquid-to-gel phase transition.

This study investigated endothelial cell mechanosensing by examining how heat shock protein 27 (HSP27) regulates DDR1 (discoidin domain receptor 1) condensate disassembly and liquid-to-gel phase transition under different shear stresses. It found that laminar shear induces rapid, transient DDR1 condensation, whereas atherogenic shear causes delayed, sustained condensation linked to YAP activation, and that HSP27 controls the DDR1 condensate dynamics. Mechanistically, the work identifies HSP27 as a regulator of shear-dependent DDR1 phase behavior, offering a potential target to modulate atherosclerosis-relevant signaling.

Infectious disease mechanisms & host-directed antivirals

TOLLIP suppresses picornavirus internalization by targeting and degrading VP1 protein through selective autophagy.

This study investigated how the host restriction factor TOLLIP regulates foot-and-mouth disease virus (FMDV) infection by targeting the viral capsid protein VP1, using the DNAJA3–autophagy pathway in the context of selective autophagy. The authors found that DNAJA3 recruits TOLLIP, enabling direct interaction with VP1 (via VP1 residues 1–37) and promoting selective autophagic degradation of VP1 to suppress viral internalization. These findings identify a specific host–viral protein axis (DNAJA3–TOLLIP–VP1) that could be exploited to develop host-directed antiviral strategies against picornaviruses like FMDV.

Strong, sustained type I IFN signaling acts cell intrinsically to impair IFNγ responses and cause tuberculosis susceptibility.

This study examined how type I interferon signaling affects immunity to Mycobacterium tuberculosis (Mtb) at the cellular level. The authors showed that strong, sustained type I IFN signaling impairs IFNγ responses cell intrinsically in a subset of infected macrophages with high type I IFN activity, and that genetic elimination of RESIST (via stabilization of transcript) altered this susceptibility phenotype. These findings identify a specific IFN signaling state that drives TB susceptibility and suggest targets for modulating harmful type I IFN effects during infection.

Perinatal health & pregnancy risk prediction

Machine learning to predict adverse perinatal outcomes: a systematic review and meta-analysis.

This systematic review and meta-analysis evaluated machine learning (ML) models that predict adverse perinatal outcomes (including preterm birth and small for gestational age) using routine clinical data, and compared their performance and risk of bias against logistic regression. Across studies published from 2015–2026, the review synthesized evidence on ML model accuracy and calibration relative to conventional regression approaches while assessing methodological limitations and bias. The work is significant for guiding the development and clinical translation of ML-based perinatal risk prediction tools with attention to validity and bias.

Clinical trial design, consensus, and implementation science

Longitudinal progression, metrics, age-dependence, and modifiers of ataxia severity in SCA27B: a multicentre study of 219 patients.

This multicentre observational study investigated longitudinal progression, age-dependence, and clinical modifiers of ataxia severity in spinocerebellar ataxia 27B (SCA27B) in 219 patients. Using item-level distribution-based analyses of repeated Scale for the Assessment and Rating of Ataxia (SARA) assessments, it characterized how SARA metrics change over time relative to aging-related impairment in healthy controls. The findings are significant for improving precision phenotyping and informing outcome measures and trial planning for this FGF14 GAA repeat-expansion–driven, likely treatable disorder.

The study produced US consensus panel recommendations on multidisciplinary care to improve safe, timely, and complete delivery of asparaginase-based therapy for acute lymphoblastic leukemia/lymphoblastic lymphoma (ALL/LBL). It highlighted operational and clinical barriers—such as complex administration, distinct toxicity, prolonged treatment duration, and variability in institutional infrastructure and supportive services—that can impede asparaginase delivery. This provides actionable guidance for care teams to reduce treatment delays and improve outcomes in patients receiving asparaginase.

REenergizeME: intermittent hypoxia-hyperoxia treatment for myalgic encephalomyelitis/chronic fatigue syndrome-protocol for a randomised, placebo-controlled trial.

This article describes the REenergizeME protocol for a randomized, placebo-controlled trial of intermittent hypoxia-hyperoxia treatment (IHHT) in adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The key scientific premise is that IHHT will induce adaptive physiological and cellular responses relevant to ME/CFS immune-metabolic dysregulation, impaired energy metabolism, vascular dysfunction, and altered oxygen handling. Clinically, the trial is designed to test whether IHHT can serve as a disease-modifying, non-pharmacological intervention for ME/CFS.

Banff Liver Allograft Pathology Group: late rejection activity is insufficiently represented in the current diagnostic framework - rationale and goals for revision.

This article is a rationale-and-goals proposal from the Banff Liver Allograft Pathology Group addressing how late liver allograft rejection is not adequately captured by the current Banff diagnostic framework. It highlights that late rejection is often clinically silent and differs histologically from classic early acute T cell–mediated rejection (TCMR), with more interface/perivenular inflammation, lymphocyte-predominant infiltrates, and fibrosis. Revising Banff criteria to better represent late rejection activity could improve diagnostic consistency and patient management after liver transplantation.

Neurological effects of encapsulated dexamethasone sodium phosphate in children aged 6-9 years with ataxia telangiectasia (NEAT): a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial.

This multicentre randomized double-blind placebo-controlled phase 3 trial tested erythrocyte encapsulated dexamethasone sodium phosphate (eDSP) for neurological outcomes in children aged 6–9 years with ataxia telangiectasia. The study was designed to evaluate whether eDSP improves safety and efficacy compared with placebo in a population with progressive cerebellar neurodegeneration and no approved therapy. If effective, eDSP would provide evidence for a corticosteroid-based disease-modifying approach in pediatric ataxia telangiectasia.

Medical device/biomaterials & engineering (including imaging tech)

Electronic Chip-Mimetic Medical Implants for Controllable Sonothermal Treatments.

This study developed and tested an implantable “electronic chip-mimetic” sonothermal platform using metal–semiconductor heterogeneous interfaces on pretreated titanium (pTi) surfaces. Under ultrasound irradiation, semiconductor coatings (TiO2, SiO2, ZnO, and Te) produced distinct in situ temperature rises (ΔT > 18°C over 15 minutes) whereas conductor coatings did not. The results support a materials/engineering approach for controllable, sterilizable implantable devices that can generate localized therapeutic heat for sonothermal treatments.

Acbd7 is essential for preserving hair cell-mediated auditory and vestibular function.

The study identified and characterized acyl-CoA binding domain-containing 7 (Acbd7) in mouse inner ear hair cells using single-cell transcriptomics of cochlear organoids and functional analyses in Acbd7-deficient mice. It found that Acbd7 is hair cell–enriched across auditory and vestibular hair cells and that Acbd7 loss causes hair cell degeneration with synaptic defects and reduced calcium currents in inner hair cells. This establishes Acbd7 as an essential sensory-maintenance gene and a potential molecular entry point for therapies for auditory-vestibular disorders.

Comparative evaluation of precision, morphology, and structural stability in AI-based dental crown design software programs.

The study compared AI-based dental crown design software with conventional CAD software by evaluating precision, morphology, and structural stability of crowns designed for a maxillary first molar digital cast. It found differences among the AI-based programs and the conventional baseline (3Shape Dental Designer), with performance assessed using quantitative measures of fit/precision and structural stability (details truncated in the abstract). This informs evidence-based selection and validation of AI CAD tools for restorative dentistry.
