Nuclear lamina integrity is required for proper spatial organization of chromatin in Drosophila

Nature Communications, 2019
The role of the nuclear lamina (NL) in chromatin architecture is still poorly understood. Here, the authors provide evidence that disruption of the NL in Drosophila cells leads to overall chromatin compaction and repositioning from the nuclear envelope ...

The von Karman equations for plates with residual strain [PDF]

, 2010
We provide a derivation of the Foppl-von Karman equations for the shape of and stresses in an elastic plate with residual strains. These might arise from a range of causes: inhomogeneous growth, plastic deformation, swelling or shrinkage driven by solvent absorption.

Engineering Assembloids to Mimic Graft‐Host Skeletal Muscle Interaction

Advanced Healthcare Materials, EarlyView.
This study develops a graft‐host skeletal muscle assembloid model combining neuromuscular organoids with tissue‐engineered constructs. Pre‐seeding decellularized muscles with myogenic cells enhances cell migration and axon invasion from the organoid. The model exhibits regenerative capacity following acute damage, advancing the understanding of human ...

Integrative genomics analysis identifies pericentromeric regions of human chromosomes affecting patterns of inter-chromosomal interactions [PDF]

arXiv, 2014
Genome-wide analysis of distributions of densities of long-range interactions of human chromosomes with each other, nucleoli, nuclear lamina, and binding sites of chromatin state regulatory proteins, CTCF and STAT1, identifies non-random highly correlated patterns of density distributions along the chromosome length for all these features.

More about areas and centers of Poncelet polygons [PDF]

arXiv, 2020
We study the locus of the Circumcenter of Mass of Poncelet polygons, and the limit of the Center of Mass (when we consider the polygon as a "homogeneous lamina") for degenerate Poncelet polygons. We also provide a proof for one of Dan Reznik invariants for billiard trajectories.

Engineered Chitosan‐Derived Nanocarrier for Efficient siRNA Delivery to Peripheral and Central Neurons

Advanced Healthcare Materials, EarlyView.
This study introduces a novel chitosan‐based nanocarrier functionalized with a neurotropic protein for efficient siRNA delivery to neurons. The polyplexes demonstrate enhanced neuronal binding, retrograde transport, and PTEN silencing, promoting axonal outgrowth.

Maturation of nuclear lamin A involves a specific carboxy-terminal trimming, which removes the polyisoprenylation site from the precursor; implications for the structure of the nuclear lamina. [PDF]

, 1989
Lamin A, a nuclear lamina protein of differentiated cells, is synthesized as a precursor of the mature molecule. Protein sequencing of the carboxyterminal 14 kDa fragment shows a lack of the last 18 residues predicted by cDNA sequencing.

Carbon‐Based Flexible Electrode for Efficient Electrochemical Generation of Reactive Chlorine Species in Tumor Therapy

Advanced Healthcare Materials, EarlyView.
A flexible electrode loaded with a carbon nanowire network (CC@C‐NWN) is developed for electrochemically generating reactive chlorine species (RCS) from abundant chloride ions in body fluids for tumor therapy. CC@C‐NWN enhances chlorine evolution, inducing redox dysregulation and synergistic apoptosis‐ferroptosis in tumor cells.

Arterial pathology in canine mucopolysaccharidosis-I and response to therapy. [PDF]

, 2011
Mucopolysaccharidosis-I (MPS-I) is an inherited deficiency of α-L-iduronidase (IdU) that causes lysosomal accumulation of glycosaminoglycans (GAG) in a variety of parenchymal cell types and connective tissues.

Chromatin phase separation and nuclear shape fluctuations are correlated in a polymer model of the nucleus

Nucleus
Abnormal cell nuclear shapes are hallmarks of diseases, including progeria, muscular dystrophy, and many cancers. Experiments have shown that disruption of heterochromatin and increases in euchromatin lead to nuclear deformations, such as blebs and ...
