Nuclear Envelope Permeability Barrier as a Fast‐Response Intracellular Mechanostat
Advanced Science, 2019 The nuclear envelope is an undisputed component of the intracellular mechanotransduction cascades which collect, process, and respond to mechanical stimuli from the environment.

Dynamics and Structure-Function Relationships of the Lamin B Receptor (LBR). [PDF]
PLoS ONE, 2017 The lamin B receptor (LBR) is a multi-spanning membrane protein of the inner nuclear membrane that is often employed as a "reporter" of nuclear envelope dynamics. We show here that the diffusional mobility of full-length LBR exhibits significant regional

Supernova Nebular Spectroscopy Suggests a Hybrid Envelope-Stripping Mechanism for Massive Stars [PDF]
Nature Astronomy (2019), 2018 When nuclear fuel in the core of a massive star with a zero-age main-sequence mass $M_{\rm ZAMS} \gtrsim 8M_\odot$ is exhausted, the central part of the iron or magnesium core collapses and forms a neutron star or a black hole. At the same time, the material above the collapsing core is rapidly ejected, leading to a stripped-envelope supernova (SESN ...

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.

Multidimensional thermal structure of magnetized neutron star envelopes [PDF]
Mon.Not.Roy.Astron.Soc. 324 (2001) 292, 1998 Recently launched x-ray telescopes have discovered several candidate isolated neutron stars. The thermal radiation from these objects may potentially constrain our understanding of nuclear physics in a realm inaccessible to terrestrial experiments. To translate the observed fluxes from neutron stars into constraints, one needs precise calculations of ...

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.

Construction of nuclear envelope shape by a high-genus vesicle with pore-size constraint [PDF]
Biophys. J. 111, 824-831 (2016), 2016 Nuclear pores have an approximately uniform distribution in the nuclear envelope of most living cells. Hence, the morphology of the nuclear envelope is a spherical stomatocyte with a high genus. We have investigated the morphology of high-genus vesicles under pore-size constraint using dynamically triangulated membrane simulations.

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 ...

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
