Mechanical Stress Triggers Premature Senescence in Cardiac Fibroblasts

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
Cellular senescence contributes to disease burden in cardiovascular disease (CVD) and aging, highlighting the need to understand its induction. In primary cardiac fibroblasts, reduced strain and increased frequency, mimicking CVD, elicit a distinct senescent phenotype compared to oxidative stress.

Multilevel analysis of nuclear dynamics in lamin perturbed fibroblasts [PDF]

open access: yes, 2010
The nuclear lamina provides structural support to the nucleus and has a central role in defining nuclear organization. Defects in its filamentous constituents, the lamins, lead to a class of diseases collectively referred to as laminopathies.

Evolving Real‐World Data and Evidence Use for New Drugs and Regenerative Medical Products Approvals in Japan—An Analysis of the 6‐Year Trend

open access: yesClinical Pharmacology &Therapeutics, Volume 118, Issue 6, Page 1405-1421, December 2025.
Several regulatory initiatives have been made to clarify the acceptability and requirements of real‐world data and real‐world evidence (RWD/E) for the benefit/risk assessment of new medical products in Japan. The objectives of this review were to characterize the use of RWD/E in regulatory applications of new medical products and to describe the ...

miR‐140‐5p Overexpression Contributes to Oxidative Stress and Mitochondrial Dysfunction in Hutchinson‐Gilford Progeria Syndrome Fibroblasts Through NRF2 Pathway

open access: yesAging Cell, Volume 24, Issue 12, December 2025.
This study identifies a novel molecular mechanism involving miR‐140‐5p that contributes to the pathogenesis of HGPS. By decreasing NRF2 expression, miR‐140‐5p overexpression results in downregulation of the NRF2/KEAP1/HO‐1 antioxidant pathway in HGPS fibroblasts, leading to increased oxidative stress and mitochondrial dysfunction, two hallmarks of ...

Separation of Coiled-Coil Structures in Lamin A/C Is Required for the Elongation of the Filament

open access: yesCells, 2020
Intermediate filaments (IFs) commonly have structural elements of a central α-helical coiled-coil domain consisting of coil 1a, coil 1b, coil 2, and their flanking linkers.

Chromosome positioning is largely unaffected in lymphoblastoid cell lines containing emerin or A-type lamin mutations [PDF]

open access: yes, 2005
Gene-poor human chromosomes are reproducibly found at the nuclear periphery in proliferating cells. There are a number of inner nuclear envelope proteins that may have roles in chromosome location and anchorage, e.g. emerin and A-type lamins.

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Induced Pluripotent Stem Cells to Study Mechanisms of Laminopathies: Focus on Epigenetics

open access: yesFrontiers in Cell and Developmental Biology, 2018
Laminopathies are a group of rare degenerative disorders that manifest with a wide spectrum of clinical phenotypes, including both systemic multi-organ disorders, such as the Hutchinson-Gilford Progeria Syndrome (HGPS), and tissue-restricted diseases ...

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

open access: yesFrontiers 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
