Nuclear envelope remnants: fluid membranes enriched in sterols and polyphosphoinositides.

open access: yesPLoS ONE, 2009
BackgroundThe cytoplasm of eukaryotic cells is a highly dynamic compartment where membranes readily undergo fission and fusion to reorganize the cytoplasmic architecture, and to import, export and transport various cargos within the cell.

Signal Transduction across the Nuclear Envelope: Role of the LINC Complex in Bidirectional Signaling

open access: yesCells, 2019
The primary functions of the nuclear envelope are to isolate the nucleoplasm and its contents from the cytoplasm as well as maintain the spatial and structural integrity of the nucleus.

Remodeling of the Nuclear Envelope and Lamina during Bovine Preimplantation Development and Its Functional Implications. [PDF]

open access: yesPLoS ONE, 2015
The present study demonstrates a major remodeling of the nuclear envelope and its underlying lamina during bovine preimplantation development. Up to the onset of major embryonic genome activation (MGA) at the 8-cell stage nuclei showed a non-uniform ...

Nuclear Envelope Regulation of Oncogenic Processes: Roles in Pancreatic Cancer

open access: yesEpigenomes, 2018
Pancreatic cancer is an aggressive and intractable malignancy with high mortality. This is due in part to a high resistance to chemotherapeutics and radiation treatment conferred by diverse regulatory mechanisms.

Deformation of the nucleus by TGFβ1 via the remodeling of nuclear envelope and histone isoforms

open access: yesEpigenetics & Chromatin, 2022
The cause of nuclear shape abnormalities which are often seen in pre-neoplastic and malignant tissues is not clear. In this study we report that deformation of the nucleus can be induced by TGFβ1 stimulation in several cell lines including Huh7.

The Arabidopsis Nuclear Pore and Nuclear Envelope [PDF]

open access: yesThe Arabidopsis Book, 2010
The nuclear envelope is a double membrane structure that separates the eukaryotic cytoplasm from the nucleoplasm. The nuclear pores embedded in the nuclear envelope are the sole gateways for macromolecular trafficking in and out of the nucleus. The nuclear pore complexes assembled at the nuclear pores are large protein conglomerates composed of ...

Nuclear Envelope Permeability Barrier as a Fast‐Response Intracellular Mechanostat

open access: yesAdvanced 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.

Nuclear envelope mechanobiology: linking the nuclear structure and function

open access: yesNucleus, 2021
The nucleus, central to cellular activity, relies on both direct mechanical input as well as its molecular transducers to sense external stimuli and respond by regulating intra-nuclear chromatin organization that determines cell function and fate.

Dynamics and Structure-Function Relationships of the Lamin B Receptor (LBR). [PDF]

open access: yesPLoS 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

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

open access: yesMicroorganisms, 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.
