- BackgroundLAMA2-related muscular dystrophy (LAMA2-MD) and SELENON-related myopathy (SELENON-RM) are rare congenital muscle diseases characterized by slowly progressive proximal muscle weakness, spinal rigidity and respiratory insufficiency. The LAST STRONG study is a natural history study to identify suitable outcome measures and reach trial readiness for LAMA2-MD and SELENON-RM.MethodsPatients had four visits over 1.5-years. Assessments included neurological examination, hand-held dynamometry (HHD), functional assessments (Motor Function Measurements(MFM)-20/32, graded and timed function tests), accelerometry, and questionnaires on quality of life, activities and participation, pain, and fatigue.ResultsA total of 27 LAMA2-MD (21 years, range 3-50; 9 males) and 11 SELENON-RM (20 years, range 3-42; 8 males) patients were included. In LAMA2-MD, mean HHD scores for neck extensors, biceps brachii, quadriceps, foot plantar flexors and handgrip strength increased (all p < 0.02). In SELENON-RM, biceps brachii and foot plantar flexors increased (p < 0.01). In LAMA2-MD, functional assessments did not change significantly. In SELENON-RM, MFM-20/32 total score and domain 1 decreased (p < 0.05), 6-Minute Walk Test (6MWT) decreased (p < 0.01) and 10-Meter Walk Test (10MWT) increased (p < 0.01). Accelerometry showed a significant change in moderate activity in LAMA2-MD (p <0.01), no changes were observed in SELENON-RM.DiscussionOver 1.5 years, LAMA2-MD remained mostly stable, while SELENON-RM showed minimal functional decline on select outcome measures. Both cohorts showed HHD increases, likely reflecting age-related development. Most measures did not capture disease progression, however MFM-20/32, 6MWT and 10MWT showed small significant changes in SELENON-RM, suggesting potential trial endpoints. - Source: PubMed

Shimazaki RuiNoguchi SatoruYoshioka WakakoTakizawa HotakeOya YasushiTakahashi YujiSato NorikoKimura YukioHayashi ShinichiroNishino Ichizo - Congenital myopathies (CMYOs) and congenital muscular dystrophies (CMDs) are rare, clinically and genetically heterogeneous neuromuscular conditions characterized by muscle weakness, usually with onset at birth or in the first few months of life. Next-generation sequencing (NGS) has significantly enhanced diagnostic capabilities and transformed the diagnostic process for such rare conditions. The aim of this study was to describe the outcomes of NGS analysis and genotypic prevalence among patients with CMYO and CMD referred for diagnostic assessment to the National Highly Specialized Service (HSS) at the Dubowitz Neuromuscular Centre in London, United Kingdom, over a period of 10 years. - Source: PubMed

In skeletal muscle, SelN is particularly important for regulating SR calcium homeostasis. It acts as a calcium sensor, modulating the activity of the sarcoplasmic reticulum calcium pump (SERCA) through a redox-dependent mechanism. Loss-of-function mutations in the gene give rise to a spectrum of skeletal muscle disorders collectively referred to as SEPN1-related myopathies (SEPN1-RM). Histopathologically, SEPN1-RM is characterized by the presence of minicores, which are localized regions within muscle fibers exhibiting mitochondrial depletion (i.e., cores) and sarcomeric disarray. As no effective therapy is currently available for SEPN1-RM, understanding SelN biology through loss-of-function models remains essential for elucidating disease mechanisms and identifying potential therapeutic targets. This review examines the current knowledge on SelN function and the pathological mechanisms underlying loss-of-function, with a particular focus on the connection between calcium handling, oxidative/ER stress, and muscle dysfunction. It also highlights emerging strategies aimed at restoring SelN activity or mitigating downstream defects, outlining potential therapeutic avenues for SEPN1-RM. - Source: PubMed

Lanza MartinaZito EsterDinoi GiorgiaBuono Antonio VittorioDe Luca AnnamariaImbrici PaolaLiantonio AntonellaConte Elena - Thyroid eye disease (TED), the most common adult orbital disease, can significantly impair patients' quality of life. Currently, effective diagnostic and predictive models for TED remain limited, making early intervention and personalized treatment for patients challenging. Oxidative stress (OS) plays an important role in pathogenesis of TED, and OS related biomarkers may serve as good candidates for TED prediction. Here, we integrated the peripheral blood bulk-RNA sequencing data and clinical features of 152 TED, 61 health control (HC), and 20 patients with simple Graves' disease (GD) to identify potential biomarkers. The intersection of TED-HC and TED-GD differentially expressed genes (DEGs) identified 1220 genes strongly correlated with TED. Enrichment analysis showed upregulation of OS-related biological processes in patients with TED. Integration of DEGs, WGCNA results, and OS-related genes identified six genes as candidate biomarkers. Machine learning algorithms suggested three critical candidate genes (KLF2, SELENON, TXNRD1) with high predictive value and were used to construct an oxidative stress-related predictive gene score (OSRPGS). Receiver operating characteristic curve confirmed the predictive value of OSRPGS with an AUC value of 0.733 (TED vs HC) and 0.705 (TED vs GD). Further patient stratification analysis confirmed that the OSRPGS was associated with tear secretion dysfunction. Furthermore, immune infiltration analysis suggested an upregulation of innate immune responses, especially the monocytes/macrophages subtypes, indicating the initiation of OS-related inflammation. Collectively, our study provides a reliable tool for TED prediction and risk assessment based on OS-related biomarkers. OSRPGS may help with the early recognition and intervention in patients with TED. - Source: PubMed
