Study of NSD2 using a dTAG system reveals their molecular mechanism and oncogenic implications in t(4;14) multiple myeloma.

Blood2026 Feb 26

The H3K36me2 methyltransferase NSD2 is deleted in Wolf-Hirschhorn syndrome and aberrantly expressed in 10-15% of multiple myeloma (MM) due to a t(4;14) translocation. Although NSD2 is thought to be a primary driver in MM, the exact molecular mechanisms by which it regulates transcription remain unclear. We applied the dTAG system to acutely degrade NSD2 and used this, in combination with time-resolved SLAM-seq, to identify 307 transcriptional targets of NSD2. Reconstitution with either wild-type NSD2 or a catalytically inactive mutant (NSD2Y1179A) showed that NSD2's transcriptional effects are almost exclusively dependent on its SET domain activity. Mechanistically, H3K36me2 deposition by NSD2 antagonizes H3K27me3 levels, and treatment with two distinct PRC2 inhibitors demonstrated that approximately half of NSD2 target genes are regulated in an H3K27me3-dependent manner. CUT&Tag analysis showed that upon NSD2 depletion there was an increase in H3K27me3 that occurred at genome-wide intergenic regions, rather than at the promoters or gene bodies of NSD2 target genes. These data suggest that NSD2, via H3K36me2, antagonizes H3K27me3 deposition likely at distal regulatory elements including enhancers, creating a chromatin landscape favorable for target gene transcription. Importantly, NSD2 target genes were enriched for key oncogenic pathways, and 24 transcription factors implicated in neurodevelopment and acute leukemia, consistent with its role in Wolf-Hirschhorn syndrome and MM. Eight of these transcription factors are known oncogenic drivers in acute leukemia or MM, highlighting a novel molecular mechanism for NSD2's role in t(4;14) MM.

Circulating microRNAs as biomarkers in pediatric epilepsy: A longitudinal cohort study.

Epilepsia2026 Feb 27

Epilepsy is the most common chronic neurological disorder in children, and approximately one third of patients develop drug-resistant seizures. Reliable biomarkers are needed to improve diagnosis, prognostic assessment, and treatment monitoring. This study evaluated four circulating microRNAs-miR-15a-5p, miR-106b-5p, miR-146a-5p, and miR-152-3p-as potential diagnostic and prognostic biomarkers in pediatric epilepsy. A total of 122 pediatric patients with epilepsy and 29 age- and sex-matched healthy controls were prospectively enrolled at Bambino Gesù Children's Hospital (Rome) between 2022 and 2025. Clinical variables included epilepsy type, etiology, seizure frequency, electroencephalography, magnetic resonance imaging, and comorbidities. Serum miRNAs were measured by reverse transcription quantitative polymerase chain reaction and normalized using the 2-ΔΔCt method, accounting for hemolysis. Nonparametric tests (Mann-Whitney, Kruskal-Wallis, Wilcoxon) were used for comparisons. Forty-three patients were reevaluated after ≥12 months to assess longitudinal expression. All four miRNAs were significantly upregulated in children with epilepsy compared to controls (p < .05). miR-146a-5p expression differed among etiological groups, being higher in structural compared with genetic or unknown etiologies (p = .014). Both miR-15a-5p and miR-106b-5p correlated with seizure frequency, showing greater expression in patients with monthly-to-daily seizures than in those with sporadic seizures or seizure-free patterns (p = .004 and p = .017). No association was found with antiseizure medications, intellectual disability, or psychiatric comorbidities. Longitudinal analysis showed a significant increase in miR-15a-5p and miR-106b-5p at follow-up (p < .01), independent of clinical outcome, whereas miR-146a-5p remained stable over time. These findings suggest that miR-15a-5p and miR-106b-5p reflect ongoing epileptic activity, whereas miR-146a-5p may relate to underlying pathophysiology rather than seizure dynamics. Circulating miRNAs represent promising, minimally invasive biomarkers in pediatric epilepsy. miR-146a-5p may aid etiologic classification, whereas miR-15a-5p and miR-106b-5p could serve as dynamic indicators of disease burden and treatment response, supporting biomarker-driven precision approaches in epilepsy care.

Wolf-Hirschhorn syndrome with growth hormone deficiency: long-term response to RhGH therapy.

Hormones (Athens, Greece)2026 Mar

To describe the long-term auxological response to recombinant human growth hormone (rhGH) therapy in a patient with genetically confirmed Wolf-Hirschhorn syndrome (WHS) and concurrent growth hormone deficiency (GHD). A male pediatric patient with genetically confirmed Wolf-Hirschhorn syndrome underwent comprehensive endocrine evaluation. Growth hormone stimulation testing revealed partial GHD. He subsequently received rhGH therapy for 11 years, with follow-up every 6 months including auxological measurements, biochemical assessments, and bone age determination. Across 11 years of rhGH, height improved from ~ - 4.2 to ~ - 1.3 SDS with normalized height velocity and a prolonged but uneventful pubertal course. No major adverse effects were observed. Muscle tone improvement was also noted with treatment initiation. To our knowledge, this is the first documented case of a male patient with WHS and confirmed GHD who received long-term rhGH therapy, resulting in marked improvement in growth. These findings underscore the importance of routine endocrine screening for GHD in WHS. Furthermore, rhGH therapy may provide benefits beyond linear growth, potentially improving hypotonia. However, additional studies are needed to substantiate this effect.

Generation of human induced pluripotent stem cell lines derived from Wolf-Hirschhorn syndrome patients with chromosomal 4p deletion.

Human cell2025 Sep 19

Wolf-Hirschhorn syndrome (WHS) is a devastating congenital disease caused by deletions on the short arm of chromosome 4 (4p), for which no curative treatments currently exist. To facilitate the development of therapeutic strategies, the development of experimental models of WHS is crucial for investigating its etiology and pathogenesis, which remain elusive. In this study, we successfully generated human induced pluripotent stem cells (hiPSCs) from three fibroblast lines from WHS patients. We then characterized these hiPSCs, along with one hiPSC line previously generated from peripheral blood mononuclear cells, as part of a Japanese nationwide project. All four hiPSC lines exhibited characteristics of self-renewal, pluripotency, and karyotypes with expected 4p deletions. Copy number variation microarray analysis revealed that these WHS-specific hiPSCs carried hemizygous deletions in p15.1-p16.3 regions, commonly encompassing 100 genes. Transcriptome analysis showed that the expression of these genes faithfully reflected hemizygous deletion in these WHS-specific hiPSCs and that these down-regulated genes were associated with the development of neural crest cells. These results indicate that WHS-specific hiPSCs can recapitulate the abnormal genomic structure genes related to and the gene expression profile observed in WHS patients. Given the limited understanding of the molecular pathogenesis of WHS, these cellular resources will be instrumental in modeling disease phenotypes and in advancing novel therapies for this syndrome.

Elevated levels of Letm1 drives mitochondrial dysfunction and cardiomyocyte stress-mediated apoptosis in cultured cardiomyocytes.

Cell communication and signaling : CCS2025 Aug 23

Cardiac ischemia, a predominant cause of heart failure, is marked by profound mitochondrial dysfunction, dysregulated ion homeostasis, and maladaptive cellular remodeling, all of which compromise cardiac performance. The mitochondrial inner membrane protein Leucine zipper-EF-hand containing Transmembrane Protein 1 (Letm1), implicated in Wolf-Hirschhorn Syndrome, is essential for mitochondrial function. Although genetic alterations in Letm1 are linked to cardiomyopathies, its specific contributions to cardiac pathophysiology, particularly in the context of ischemic heart disease, remain poorly defined. This study aims to elucidate the role of Letm1 in ischemic cardiac pathology and its mechanistic impact on cardiomyocyte function. Letm1 expression was assessed in human and murine models of heart failure due to ischemic cardiomyopathy (ICM) and cardiac hypertrophy. Letm1 was overexpressed in neonatal rat ventricular cardiomyocytes, adult mouse cardiomyocytes, and human induced pluripotent stem cell (iPSC)-derived cardiomyocytes to study mitochondrial function (Seahorse assays), structural and molecular remodeling (fluorescence microscopy, transmission electron microscopy (TEM), qPCR, immunoblotting), transcriptomic/proteomic profiles, calcium handling and electrophysiology (patch-clamp), autophagic flux (Bafilomycin A1, LC3-RFP-GFP), and cell survival. Letm1 was markedly upregulated in ICM in both human and murine hearts, but unchanged in hypertrophic heart failure. Overexpression of Letm1 in cardiomyocytes resulted in profound mitochondrial dysfunction, including downregulation of oxidative phosphorylation (OXPHOS) genes, impaired membrane potential, reduced ATP output, increased proton leak, and elevated ROS levels. A metabolic shift toward glycolysis was observed, accompanied by reduced fatty acid oxidation. Electron microscopy revealed mitochondrial fragmentation, mitophagic vesicles, and sarcomeric disarray. Transcriptomic and proteomic analyses highlighted dysregulation of genes linked to mitochondrial organization, ion transport, and autophagy. Electrophysiologically, Letm1 reduced L-type Ca2+ current density and significantly shortened action potential duration, leading to impaired contractility. Letm1 overexpression activated upstream autophagy regulators (AMPK, ULK1) and enhanced LC3-II and p62 accumulation, but autophagic flux was impaired, as confirmed by LC3-RFP-GFP reporter and exacerbated by Bafilomycin A1 treatment. This dysregulated autophagy was coupled with mitochondrial stress, increased apoptosis (cleaved caspases), and reduced cardiomyocyte viability. This study indicates that Letm1 upregulation drives mitochondrial dysfunction, electrophysiology alterations, and activation of autophagy and apoptosis, culminating in cardiomyocyte injury in ischemic cardiomyopathy. By disrupting OXPHOS, calcium handling, and cell survival pathways, Letm1 contributes to ischemic remodeling and cardiac dysfunction. Targeting Letm1 presents a promising therapeutic strategy to alleviate ischemic damage and preserve cardiac function.
