Nuclear filaments: role in chromosomal positioning and gene expression

Nucleus, 2020
Nuclear lamins form an elastic meshwork underlying the inner nuclear membrane and provide mechanical rigidity to the nucleus and maintain shape. Lamins also maintain chromosome positioning and play important roles in several nuclear processes like ...

Structural and Mechanical Aberrations of the Nuclear Lamina in Disease

Cells, 2020
The nuclear lamins are the major components of the nuclear lamina in the nuclear envelope. Lamins are involved in numerous functions, including a role in providing structural support to the cell and the mechanosensing of the cell.

Extracts Prepared from a Canadian Toxic Plant Induce Light-Dependent Perinuclear Vacuoles in Human Cells

Toxins, 2021
We are investigating plant species from the Canadian prairie ecological zone by phenotypic cell assays to discover toxins of biological interest. We provide the first report of the effects of extracts prepared from the shrub Symphoricarpos occidentalis ...

Genomic instability and DNA replication defects in progeroid syndromes [PDF]

, 2018
Progeroid syndromes induced by mutations in lamin A or in its interactors – named progeroid laminopathies – are model systems for the dissection of the molecular pathways causing physio- logical and premature aging.

Deciphering Nuclear Mechanobiology in Laminopathy [PDF]

Cells, 2019
Extracellular mechanical stimuli are translated into biochemical signals inside the cell via mechanotransduction. The nucleus plays a critical role in mechanoregulation, which encompasses mechanosensing and mechanotransduction. The nuclear lamina underlying the inner nuclear membrane not only maintains the structural integrity, but also connects the ...

Alterations to nuclear architecture and genome behavior in senescent cells. [PDF]

, 2007
The organization of the genome within interphase nuclei, and how it interacts with nuclear structures is important for the regulation of nuclear functions.

Aging of Hutchinson-Gilford progeria syndrome fibroblasts is characterised by hyperproliferation and increased apoptosis [PDF]

, 2004
Hutchinson-Gilford progeria syndrome is a rare genetic disorder that mimics certain aspects of aging prematurely. Recent work has revealed that mutations in the lamin A gene are a cause of the disease.

Mouse models of the laminopathies [PDF]

Experimental Cell Research, 2007
The A and B type lamins are nuclear intermediate filament proteins that comprise the bulk of the nuclear lamina, a thin proteinaceous structure underlying the inner nuclear membrane. The A type lamins are encoded by the lamin A gene (LMNA). Mutations in this gene have been linked to at least nine diseases, including the progeroid diseases Hutchinson ...

Micro-Scale Topography Triggers Dynamic 3D Nuclear Deformations. [PDF]

Adv Sci (Weinh)
Microgroove substrates induce significant dynamic 3D nuclear deformations in different cell types. These deformations are principally driven by cell adhesion forces and are associated with rapid changes in perinuclear stiffness. The observation of abnormal nuclear deformations in cells derived from laminopathy patients opens the possibility of using ...
