Cell Cycle Dynamics of the Nuclear Envelope

The Scientific World Journal, 2003
The nuclear envelope (NE) consists of an inner and an outer membrane, nuclear pore complexes, and the underlying nuclear lamina, a filamentous scaffold structure formed by lamins.

Lamin A/C Mechanotransduction in Laminopathies

Cells, 2020
Mechanotransduction translates forces into biological responses and regulates cell functionalities. It is implicated in several diseases, including laminopathies which are pathologies associated with mutations in lamins and lamin-associated proteins ...

Changes in the nuclear distribution of DNA polymerase alpha and PCNA/cyclin during the progress of the cell cycle, in a cell-free extract of Xenopus eggs [PDF]

, 1989
The nuclear distribution of DNA polymerase alpha and PCNA/cyclin in embryonic nuclei has been investigated, in a cell-free extract of Xenopus eggs that recapitulates a basic cell-cycle in vitro, by indirect immunofluorescence microscopy.

Cytoskeletal influences on nuclear shape in granulocytic HL-60 cells [PDF]

, 2004
Background During granulopoiesis in the bone marrow, the nucleus differentiates from ovoid to lobulated shape. Addition of retinoic acid (RA) to leukemic HL-60 cells induces development of lobulated nuclei, furnishing a convenient model system for ...

Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

Advanced Science, EarlyView.
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

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

Advanced Science, EarlyView.
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.

Hepatocyte-Specific Deletion of Mouse Lamin A/C Leads to Male-Selective SteatohepatitisSummary

Cellular and Molecular Gastroenterology and Hepatology, 2017
Background & Aims: Lamins are nuclear intermediate filament proteins that comprise the major components of the nuclear lamina. Mutations in LMNA, which encodes lamins A/C, cause laminopathies, including lipodystrophy, cardiomyopathy, and premature aging

Interplay of the nuclear envelope with chromatin in physiology and pathology

Nucleus, 2020
The nuclear envelope compartmentalizes chromatin in eukaryotic cells. The main nuclear envelope components are lamins that associate with a panoply of factors, including the LEM domain proteins.

Internal iamin structures within G1 nuclei of human dermal fibroblasts [PDF]

, 1993
The nuclear lamina is a mesh-like network of fibres subjacent to the inner nuclear membrane that is believed to be involved in the specific spatial reorganisation of chromatin after mitosis.
