Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

The farnesyl transferase inhibitor (FTI) lonafarnib improves nuclear morphology in ZMPSTE24-deficient fibroblasts from patients with the progeroid disorder MAD-B

Nucleus, 2023
Several related progeroid disorders are caused by defective post-translational processing of prelamin A, the precursor of the nuclear scaffold protein lamin A, encoded by LMNA.

Profiling Co‐Occurrent Morphological Phenotypes and Their Degree of Expression Severity in Vacuolated Cells by Holo‐Tomographic Flow Cytometry and Fractal Analysis

Advanced Intelligent Systems, Volume 8, Issue 7, July 2026.
HTFC gets 3D refractive index tomograms of flowing cells. Label‐free monocytes are engineered to express patterns of cytoplasmic vacuoles. From the tomogram, an efficient dimensionality reduction is operated. Interpretable features are extracted to classify the expression severity of phenotypes coexisting in each cell, visually represented by a seven ...

Lipodystrophic laminopathies: Diagnostic clues [PDF]

Nucleus, 2018
The nuclear lamina is a complex reticular structure that covers the inner face of the nucleus membrane in metazoan cells. It is mainly formed by intermediate filaments called lamins, and exerts essential functions to maintain the cellular viability. Lamin A/C provides mechanical steadiness to the nucleus and regulates genetic machinery.

Cytokine Profile in Striated Muscle Laminopathies: New Promising Biomarkers for Disease Prediction

Cells, 2020
Laminopathies are a wide and heterogeneous group of rare human diseases caused by mutations of the LMNA gene or related nuclear envelope genes. The variety of clinical phenotypes and the wide spectrum of histopathological changes among patients carrying ...

Mitotic defects lead to pervasive aneuploidy and accompany loss of RB1 activity in mouse LmnaDhe dermal fibroblasts. [PDF]

PLoS ONE, 2011
Lamin A (LMNA) is a component of the nuclear lamina and is mutated in several human diseases, including Emery-Dreifuss muscular dystrophy (EDMD; OMIM ID# 181350) and the premature aging syndrome Hutchinson-Gilford progeria syndrome (HGPS; OMIM ID# 176670)

LMNA mutation leads to cardiac sodium channel dysfunction in the Emery-Dreifuss muscular dystrophy patient

Frontiers in Cardiovascular Medicine, 2022
Pathogenic variants in the LMNA gene are known to cause laminopathies, a broad range of disorders with different clinical phenotypes. LMNA genetic variants lead to tissue-specific pathologies affecting various tissues and organs. Common manifestations of

Nuclear dysfunction in aging and neurodegeneration

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract Neurodegenerative diseases are characterized by a loss of neuronal function and structure, often in a region‐specific manner. Multiple factors contribute to neuronal dysfunction and death, including pathogenic protein buildup, protein mislocalization, and inflammation. Despite extensive research, the common mechanisms driving neurodegeneration

Heterozygous LMNA mutation-carrying iPSC lines from three cardiac laminopathy patients

Stem Cell Research, 2022
LMNA-related dilated cardiomyopathy (LMNA-DCM) is caused by pathogenic variants in the LMNA gene and is characterized by left ventricular chamber enlargement, reduced systolic function, and arrhythmia.
