Breakthrough Discovery at NYU Abu Dhabi Links Cellular DNA Structure to Obesity Mechanisms
Researchers at New York University Abu Dhabi (NYUAD) have unveiled a groundbreaking study demonstrating how the three-dimensional organization of DNA within cells profoundly impacts fat storage, energy metabolism, and overall metabolic health. This research, conducted at NYUAD's Center for Genomics and Systems Biology (CGSB), highlights the protein nuclear myosin 1 (NM1) as a pivotal regulator in maintaining healthy adipose tissue function. Published in the prestigious journal Cell Death & Disease on February 26, 2026, the findings offer fresh insights into obesity's cellular roots, potentially paving the way for innovative therapies targeting metabolic disorders.
The study reveals that disruptions in NM1 lead to abnormal fat cell development, resulting in fewer but significantly larger adipocytes, increased visceral fat accumulation, and heightened inflammation—hallmarks of obesity and related conditions like type 2 diabetes. By integrating advanced techniques such as ATAC-seq for chromatin accessibility and RNA-seq for gene expression, the team established NM1's essential role in coordinating genomic architecture with metabolic processes during adipocyte differentiation.
This discovery is particularly timely for the United Arab Emirates, where obesity rates among adults hover around 30-44%, with projections indicating nearly 95% of women and 94% of men could be overweight or obese by 2050, according to recent reports from the World Obesity Federation.
The Growing Obesity Challenge in the UAE and Regional Context
Obesity has emerged as a pressing public health issue in the UAE, driven by rapid urbanization, dietary shifts toward processed foods, sedentary lifestyles, and genetic predispositions. Data from the UAE Healthy Future Study, involving NYUAD researchers, underscores the prevalence: approximately 31.7% of adults were obese in 2025, with metabolic syndrome affecting a significant portion of the population. These trends contribute to soaring rates of type 2 diabetes, cardiovascular disease, and other comorbidities, straining healthcare resources.
In this landscape, UAE universities like NYUAD are at the forefront of addressing national health priorities through cutting-edge research. The CGSB, established to advance life sciences in the region, focuses on genomics and systems biology to tackle diseases like diabetes and obesity, aligning with Abu Dhabi's vision for innovation-driven healthcare.
Understanding DNA Organization: The 3D Genome and Its Role in Cells
At the heart of the NYU Abu Dhabi study is the concept of chromatin organization, where DNA (deoxyribonucleic acid, the molecule carrying genetic instructions) is packaged into a dynamic three-dimensional structure inside the cell nucleus. This 3D genome architecture determines which genes are accessible for transcription—the process turning genetic code into functional proteins.
Chromatin, a complex of DNA and proteins called histones, folds into loops and domains that bring distant genetic regions together, facilitating gene regulation. In fat cells (adipocytes), proper chromatin looping supports the expression of genes involved in lipid metabolism, mitochondrial biogenesis, and energy homeostasis. Disruptions in this organization can shift cells from oxidative phosphorylation (efficient energy production) to less optimal aerobic glycolysis, impairing fat tissue health.
The study meticulously maps how NM1, an actomyosin motor protein associated with chromatin, maintains this architecture. Step-by-step: (1) NM1 binds to chromatin via actin filaments; (2) It facilitates enhancer-promoter interactions; (3) This activates adipogenic transcription factors like C/EBPα and PPARγ; (4) Proper gene expression ensures balanced adipocyte proliferation and mitochondrial function.
Nuclear Myosin 1 (NM1): The Key Protein Unlocking Metabolic Secrets
Nuclear myosin 1 (NM1), also known as MYO1C in humans, acts as a molecular motor within the nucleus, shuttling along actin tracks to remodel chromatin. The NYUAD team generated NM1-knockout (KO) mouse embryonic fibroblasts (MEFs) and mesenchymal stem cells (MSCs), revealing its indispensable role.
In NM1-deficient cells, chromatin accessibility at enhancers near key genes—such as Cebpa (CCAAT/enhancer-binding protein alpha), Plin2 (perilipin 2 for lipid droplets), and Pink1 (PTEN-induced kinase 1 for mitophagy)—is reduced. This cascades into defective adipogenesis: MSCs differentiate into fewer, hypertrophied adipocytes (66% larger area), with downregulated markers like PPARγ and FABP4.
In vivo, NM1 KO mice gained 35% more body weight by 12 months, with visceral adipose tissue comprising 11% of body mass (vs. 4.6% in wild-type). Epididymal white adipose tissue (eWAT) showed repressed mitochondrial pathways and upregulated pro-inflammatory cytokines like IFNγ, IL-33, and TNF, mimicking human obesity phenotypes.

Methodology: Cutting-Edge Genomics at NYU Abu Dhabi
The research employed state-of-the-art multi-omics approaches. ATAC-seq (Assay for Transposase-Accessible Chromatin with sequencing) identified open chromatin regions, while RNA-seq quantified transcriptome changes in NM1 KO vs. wild-type MEFs. Concordant peaks (overlapping accessibility and expression shifts) pinpointed NM1-regulated networks.
Gene regulatory modeling (Inferelator) integrated data to infer transcription factor motifs (e.g., KLF6, FOXO3). In vivo phenotyping used microCT for body composition, histology for adipocyte sizing, and IPA (Ingenuity Pathway Analysis) for pathway enrichment. Cross-species validation linked mouse NM1 to human MYO1C via GTEx eQTL data, confirming metabolic trait associations.
This rigorous pipeline exemplifies NYUAD's genomic infrastructure, supported by Core Technology Platforms.
Implications for Obesity Treatment and UAE Health Initiatives
By targeting NM1/MYO1C pathways, future interventions could restore chromatin dynamics, promoting healthy adipocyte hyperplasia over hypertrophy and curbing inflammation. This shifts focus from caloric restriction to cellular reprogramming, potentially via small molecules enhancing NM1 activity or gene therapy.
In the UAE, where metabolic diseases burden the healthcare system (e.g., diabetes prevalence ~12.3%), such research aligns with national strategies like the UAE Centennial 2071 and Abu Dhabi Public Health initiatives. NYUAD's findings complement prior CGSB work on oral microbiome-obesity links, enriching UAE Healthy Future Study data.
