Previous studies have reported that EGFR ligands enhance glucose homeostasis through various mechanisms across different tissues. However, epigen, the latest EGFR ligand, has not been thoroughly investigated regarding its impact on energy metabolism. In this study, we employed both in vivo gain-of-function and loss-of-function approaches to investigate the role of epigen in metabolic regulation using diet-induced obesity (DIO) and streptozotocin (STZ)-induced diabetic mice. Our findings, which align with previous research on other EGFR ligands, provide the first evidence that epigen is crucial for glucose homeostasis. It promotes the release of endogenous insulin, enhances glucose uptake in adipocytes and muscle, improves glycolysis and respiration utilization in adipose tissues of DIO mice, and increases pancreatic beta cell mass in STZ-induced diabetic mice. Overall, our findings suggest that epigen could be a potential therapeutic target for managing both type 2 and type 1 diabetes, warranting further exploration in clinical settings.","PeriodicalId":19020,"journal":{"name":"Molecular Therapy","volume":"19 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inner ear labyrinthine hemorrhage (IELH) is a potentially significant cause. Our study focused on the NLR family pyrin domain containing 3 (NLRP3) inflammasome activation following IELH and the protective role of the NLRP3 inhibitor CY-09. In mice with IELH, significant increases in hearing thresholds and vestibular dysfunction were observed compared to control groups. The activation of the NLRP3 inflammasome and other pro-inflammatory factors were markedly elevated, leading to potential damage in cochlear and vestibular hair cells via the Gasdermin D (GSDMD)-mediated pyroptosis pathway. Treatment with CY-09 significantly ameliorated hearing loss and vestibular dysfunction via inhibition of the NLRP3 inflammasome and associated cell pyroptosis. These results highlight the critical roles of the NLRP3 inflammasome and pyroptosis in IELH-induced SSNHL and suggest the NLRP3/caspase-1/GSDMD pathway as a therapeutic target for managing this condition.

Assessing the stability of mRNA sequences and polyA tail lengths is crucial to minimize adverse effects and ensure drug efficacy. However, accurately measuring long homopolymeric nucleotides remains technically challenging, and a specialized method for IVT mRNAs is lacking. We introduced 3AIM-seq, a technique optimized experimentally and analytically for sequencing 3′ polyA tails in IVT mRNAs. To generate high-quality data, we used a ligation-free adapter followed by 3′ end amplification to prepare high-throughput sequencing libraries. The 3AIM-seq algorithm employed a sliding window approach to base quality scores, providing higher resolution and accuracy than base-calling method, and distinguishing polyA length differences as small as ±5 bp. Using <ce:italic>in silico</ce:italic> synthetic standard spike-in experiments, the method estimated the homogeneity of polyA tail lengths at the individual DNA molecule level in IVT mRNAs with various polyA tail structures. Although polyA tail of up to 70 bases were accurately measured, stretches exceeding 100 bases exhibited high heterogeneity for length, highlighting the importance of thorough assessments. Therefore, 3AIM-seq is a reliable method for evaluating the structural integrity of IVT mRNA products before clinical use.","PeriodicalId":19020,"journal":{"name":"Molecular Therapy","volume":"19 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the clinical efficacy and safety of short-term blinatumomab treatment in two patients with severe, refractory generalized MG. Both individuals had been experiencing a persistent disease burden with myasthenic crises leading to severe disability, despite multimodal immunotherapy. Following treatment with blinatumomab, both patients showed rapid and sustained clinical improvements, reflected in significant reductions in MG-specific scores (MG-ADL, QMG, and revised MG Quality of Life-15), further patient-reported outcomes, digital activity markers, and gait analyses. Laboratory findings revealed persistent B-cell depletion in patient #1, whereas patient #2 demonstrated clinical improvement and autoantibody reduction despite B-cell repopulation by day 106. Both patients experienced grade 1 cytokine release syndrome during initial treatment phases, but no neurotoxicity or severe adverse events were observed.

Despite considerable progress in understanding of DNA methylation (DNAm), the mechanisms that orchestrate its coordinated regulation across the genome remain largely elusive. Recent breakthroughs in sequencing technologies and epigenetic editing tools enable more comprehensive exploration of these epigenetic interactions. Regulation of DNAm seems to be organized within epigenetic networks characterized by complex feedback mechanisms acting locally, between homologous alleles, and across the entire genome. This crosstalk is facilitated by an interplay of various molecular components, including distinct variants of epigenetic writers and erasers; methylation-sensitive binding of transcription factors and other regulatory proteins that recruit DNA methyltransferases; cross-regulation between DNAm and the histone code; 3D chromatin conformation; regulatory effects mediated by long non-coding RNAs (lncRNAs); and potentially by assimilation during homologous recombination events. This review explores how these diverse epigenetic mechanisms interact to collectively shape the methylome, and thereby control developmental and disease processes.","PeriodicalId":19020,"journal":{"name":"Molecular Therapy","volume":"11 1","pages":""},"PeriodicalIF":12.4,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144516108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
