Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

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

, 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 ...

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Lamin chromatin binding is modulated by interactions of different LAP2α domains with lamins and chromatin

iScience
Summary: Lamins A and C are components of the lamina at the nuclear periphery and associate with heterochromatin. A distinct, relatively mobile pool of lamin A/C in the nuclear interior associates with euchromatic regions and with lamin-associated ...

Engineered extracellular vesicles for precision renal therapy: Bioengineering strategies and clinical translation

Interdisciplinary Medicine, EarlyView.
Engineered extracellular vesicles (EVs) offer a versatile platform for kidney‐targeted therapy. This review summarizes bioengineering strategies, including cargo loading, surface modification, biomimetic fabrication, and biomaterial integration. We highlight translational challenges and propose future solutions to accelerate the clinical application of

Robert Feulgen Lecture | LAMINS IN NUCLEAR ORGANISATION AND CHROMATIN REGULATION

European Journal of Histochemistry
Lamins form a filamentous network at the nuclear envelope that anchors heterochromatin and repressed genes to the nuclear periphery. Lamin A also exists as a non-filamentous pool in the nuclear interior, where it interacts with lamin-associated ...

The metalloproteinase ADAM17 promotes acute lung inflammatory responses during pancreatitis

British Journal of Pharmacology, EarlyView.
Background and Purpose Acute pancreatitis (AP) is a multifactorial upper gastrointestinal inflammatory disorder that in severe cases (~20% of all AP) is associated with substantial morbidity and mortality, the latter coincident with multiorgan dysfunction, particularly acute lung injury (ALI).

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

, 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.
