Lamin A/C sustains PcG protein architecture, maintaining transcriptional repression at target genes [PDF]

open access: yes, 2015
Beyond its role in providing structure to the nuclear envelope, lamin A/C is involved in transcriptional regulation. However, its cross talk with epigenetic factors--and how this cross talk influences physiological processes--is still unexplored.

A Cell-Intrinsic Interferon-like Response Links Replication Stress to Cellular Aging Caused by Progerin

open access: yesCell Reports, 2018
Summary: Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease caused by a truncated lamin A protein (progerin) that drives cellular and organismal decline.

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

open access: yesAdvanced 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.

CK2α Deficiency Drives Myocardial Fibrosis via Desmin‐Induced Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
CK2α preserves mitochondrial homeostasis by phosphorylating Desmin to recruit Cryab, ensuring proper filament assembly. CK2α deficiency disrupts this interaction, causing mitochondrial dysfunction, metabolic shifts, bioenergetic failure, and oxidative stress—ultimately establishing a pro‐fibrotic environment that drives cardiac fibrosis.

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

open access: yesAnnals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Studies of the lamin proteinase reveal multiple parallel biochemical pathways during apoptotic execution [PDF]

open access: yes, 1995
Although specific proteinases play a critical role in the active phase of apoptosis, their substrates are largely unknown. We previously identified poly(ADP-ribose) polymerase (PARP) as an apoptosis-associated substrate for proteinase(s) related to ...

Mouse models for understanding the molecular mechanism of bone disease in Hutchinson-Gilford progeria syndrome [PDF]

open access: yes, 2011
Aging is a complex process affecting all people. Intense research is applied to elucidate the biological basis of aging and disease that develop with aging.

Quantitative Analysis of Nuclear Lamins Imaged by Super-Resolution Light Microscopy

open access: yesCells, 2019
The nuclear lamina consists of a dense fibrous meshwork of nuclear lamins, Type V intermediate filaments, and is ~14 nm thick according to recent cryo-electron tomography studies.

Harnessing Cellular Feeling: Epigenetic to Mechanical Memory as a Framework for Stem Cell Manufacturing

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Stem cell‐based therapies hold transformative potential for regenerative medicine, yet their progress is constrained by persistent variability in manufacturing and clinical performance. Conventional frameworks such as Quality by Design (QbD), though effective for drugs and biologics, struggle to accommodate the dynamic nature of living cell ...

From lamins to lamina: a structural perspective [PDF]

open access: yes, 2018
Lamin proteins are the major constituents of the nuclear lamina, a proteinaceous network that lines the inner nuclear membrane. Primarily, the nuclear lamina provides structural support for the nucleus and the nuclear envelope; however, lamins and their ...
