[Basic Research in Cardiology] To evaluate the role of Integrin α3 (ITGA3) in vivo, scientists generated a mouse line with cardiomyocyte-specific ITGA3 depletion (ITGA3 KO). ITGA3 KO mice were characterized under baseline conditions and after permanent LAD ligation by echocardiography.
[Nature Genetics] Researchers exploited the value of cross-species analysis and developed single-cell methodologies in skeletal tissues to define the critical endosteal compartment that regulates bone turnover.
[Cellular and Molecular Life Sciences] Investigators examined the effects of Fhod3 depletion in primary cultured cardiomyocytes derived from Fhod3flox neonates. Long-range time-lapse imaging revealed that Fhod3 depletion around birth using muscle creatine kinase-Cre caused sarcomere disruption only in cells that had undergone mitosis.
[Cellular Signalling] Scientists confirmed that histone H3 lysine 18 lactylation (H3K18la) is abnormally elevated in osteogenic vascular smooth muscle cells. They demonstrated that H3K18la directly binds to the promoter region of AlkB homolog 5 (ALKBH5) and positively regulates its transcription.
[Biochimica Et Biophysica Acta-Molecular Basis of Disease] USP18 acts as a context-dependent regulator of muscle regeneration independent of its deISGylation function. The authors identified USP18 as a dual modulator of myogenesis and highlighted its potential as a therapeutic target in inflammatory muscle disease.
[Epicrispr Biotechnologies] Epicrispr Biotechnologies announced the completion of enrollment and dosing in the dose-escalation portion of its first-in-human clinical trial evaluating EPI-321 for facioscapulohumeral muscular dystrophy.
[Nature Immunology] Researchers identified stress-responsive protein arachidonate lipoxygenase-15 (ALOX15) is a critical component of mitochondrial antiviral innate immunity.
[Emerging Microbes & Infections] Investigators provided the first unequivocal evidence of human CNS involvement by detecting Sindbis virus RNA directly in the cerebrospinal fluid of four autochthonous patients presenting with acute neurological symptoms in south eastern Tuscany, Italy, July-August 2025.
[Nature Communications] Scientists showed that CD11clo monocyte-derived cells, the subset of lung cells that is most permissive for Mtb viability during chronic infection, express lower levels of interferon-gamma (IFNγ) signaling proteins, resulting in reduced responses to IFNγ compared to alveolar macrophages and CD11chi monocyte-derived cells.
