Closed mitosis requires local disassembly of the nuclear envelope

bioRxiv, 2019
At the end of mitosis, eukaryotic cells must segregate the two copies of their replicated genome into two new nuclear compartments 1 . They do this either by first dismantling and later reassembling the nuclear envelope in an ‘open mitosis’ or by ...

Tidal Novae in Compact Binary White Dwarfs [PDF]

, 2012
Compact binary white dwarfs (WDs) undergoing orbital decay due to gravitational radiation can experience significant tidal heating prior to merger. In these WDs, the dominant tidal effect involves the excitation of outgoing gravity waves in the inner ...

Expansion Microscopy Reveals Plasmodium falciparum Blood-Stage Parasites Undergo Anaphase with A Chromatin Bridge in the Absence of Mini-Chromosome Maintenance Complex Binding Protein

Microorganisms, 2021
The malaria parasite Plasmodium falciparum undergoes closed mitosis, which occurs within an intact nuclear envelope, and differs significantly from its human host. Mitosis is underpinned by the dynamics of microtubules and the nuclear envelope.

Cisternal Organization of the Endoplasmic Reticulum during Mitosis [PDF]

, 2009
The endoplasmic reticulum (ER) of animal cells is a single, dynamic, and continuous membrane network of interconnected cisternae and tubules spread out throughout the cytosol in direct contact with the nuclear envelope.

Parvoviruses cause nuclear envelope breakdown by activating key enzymes of mitosis. [PDF]

PLoS Pathogens, 2013
Disassembly of the nuclear lamina is essential in mitosis and apoptosis requiring multiple coordinated enzymatic activities in nucleus and cytoplasm. Activation and coordination of the different activities is poorly understood and moreover complicated as

LINCing Senescence and Nuclear Envelope Changes

Cells, 2022
The nuclear envelope (NE) has emerged as a nexus for cellular organization, signaling, and survival. Beyond its role as a barrier to separate the nucleoplasm from the cytoplasm, the NE’s role in supporting and maintaining a myriad of other functions has ...

Tau‐induced nuclear envelope invagination causes a toxic accumulation of mRNA in Drosophila

Aging Cell, 2018
The nucleus is a spherical dual‐membrane bound organelle that encapsulates genomic DNA. In eukaryotes, messenger RNAs (mRNA) are transcribed in the nucleus and transported through nuclear pores into the cytoplasm for translation into protein.

Radiation hydrodynamical simulations of eruptive mass Loss from progenitors of Type Ibn/IIn supernovae

, 2020
Observations suggest that some massive stars experience violent and eruptive mass loss associated with significant brightening that cannot be explained by hydrostatic stellar models. This event seemingly forms dense circumstellar matter (CSM).

Fine Structure Zonal Flow Excitation by Beta-induced Alfven Eigenmode [PDF]

, 2016
Nonlinear excitation of low frequency zonal structure (LFZS) by beta-induced Alfven eigenmode (BAE) is investigated using nonlinear gyrokinetic theory. It is found that electrostatic zonal flow (ZF), rather than zonal current, is preferentially excited ...
