Nuclear envelope morphology change upon repetitive treatment with modified antisense oligonucleotides targeting Hutchinson-Gilford Progeria Syndrome

open access: yesBiochemistry and Biophysics Reports, 2023
We present the influence of treating progeroid fibroblasts with two modified antisense oligonucleotides (ONs) on the nuclear envelope. Two modified ONs were designed to block ribosome binding during translation and spliceosome binding at the cryptic ...

Samp1 Mislocalization in Emery-Dreifuss Muscular Dystrophy

open access: yesCells, 2018
LMNA linked-Emery-Dreifuss muscular dystrophy (EDMD2) is a rare disease characterized by muscle weakness, muscle wasting, and cardiomyopathy with conduction defects.

Morphological Characterization of the Radiation Sensitive Cell Line, XRS-5 [PDF]

open access: yes, 1993
Morphometric analysis was performed on the radiation sensitive Chinese hamster ovary (CHO) xrs-5 cell line, reverting xrs-5 cells and parental K1 cells. Several ultrastructural parameters (increased nuclear envelope membrane separation, cell and nuclear ...

Calcium signals can freely cross the nuclear envelope in hippocampal neurons: somatic calcium increases generate nuclear calcium transients

open access: yesBMC Neuroscience, 2007
Background In hippocampal neurons, nuclear calcium signaling is important for learning- and neuronal survival-associated gene expression. However, it is unknown whether calcium signals generated by neuronal activity at the cell membrane and propagated to

Why Do Stars Turn Red? I. Post-Main-Sequence Expansion Mechanism [PDF]

open access: yesarXiv
We revisit the long-standing question: Why do post-main-sequence stars evolve into red giants (RGs) or red supergiants (RSGs)? Using the 1D stellar evolution code MESA, we perform numerical experiments to compare stellar models that successfully transition into RGs/RSGs with those that remain blue.

Nuclear envelopathies: a complex LINC between nuclear envelope and pathology

open access: yesOrphanet Journal of Rare Diseases, 2017
Since the identification of the first disease causing mutation in the gene coding for emerin, a transmembrane protein of the inner nuclear membrane, hundreds of mutations and variants have been found in genes encoding for nuclear envelope components ...

Forming a clumpy circumstellar material in energetic pre-supernova activity [PDF]

open access: yesarXiv
We demonstrate by three-dimensional hydrodynamical simulations of energy deposition into the envelope of a red supergiant (RSG) model the inflation of a Rayleigh-Taylor unstable envelope that forms a compact clumpy circumstellar material (CSM).

Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast. [PDF]

open access: yes, 2019
Production of healthy gametes in meiosis relies on the quality control and proper distribution of both nuclear and cytoplasmic contents. Meiotic differentiation naturally eliminates age-induced cellular damage by an unknown mechanism.

Thermonuclear Heating of Accreting Neutron Stars [PDF]

open access: yesarXiv
We describe a new method to incorporate thermonuclear heating in the envelope of accreting neutron star into long term simulations of their thermal evolution. We obtain boundary conditions for the heat exchange between the envelope and the crust based on stationary models which include nuclear burning and validate these values comparing to the results ...

A multistage sequencing strategy pinpoints novel candidate alleles for Emery-Dreifuss muscular dystrophy and supports gene misregulation as its pathomechanism

open access: yesEBioMedicine, 2020
Background: As genome-wide approaches prove difficult with genetically heterogeneous orphan diseases, we developed a new approach to identify candidate genes.
