Nuclear Pore Proteins in Regulation of Chromatin State
Nuclear pore complexes (NPCs) are canonically known to regulate nucleocytoplasmic transport. However, research efforts over the last decade have demonstrated that NPCs and their constituent nucleoporins (Nups) also interact with the genome and perform ...

Hutchinson-Gilford progeria syndrome (HGPS) is a rare premature aging disease caused by a mutation in LMNA. A G608G mutation in exon 11 of LMNA is responsible for most HGPS cases, generating a truncated protein called “progerin”.

Diffusion of Macromolecules across the Nuclear Pore Complex
Nuclear pore complexes (NPCs) are very selective filters that monitor the transport between the cytoplasm and the nucleoplasm. Two models have been suggested for the plug of the NPC. They are (i) it is a reversible hydrogel or (ii) it is a polymer brush.

Nuclear pore density controls heterochromatin reorganization during senescence
Oncogene induced senescence (OIS) is a cell cycle arrest program triggered by oncogenic signalling. An important characteristic of OIS is activation of the senescence associated secretory phenotype (SASP)1 which can reinforce cell cycle arrest, lead to ...

Regulator of TElomere Length Helicase 1 (RTEL1) is a helicase required for telomere maintenance and genome replication and repair. RTEL1 has been previously shown to participate in the nuclear export of small nuclear RNAs.

Pore timing:the evolutionary origins of the nucleus and nuclear pore complex [PDF]
The name “eukaryote” is derived from Greek, meaning “true kernel”, and describes the domain of organisms whose cells have a nucleus. The nucleus is thus the defining feature of eukaryotes and distinguishes them from prokaryotes (Archaea and Bacteria ...

Simple rules for passive diffusion through the nuclear pore complex
Passive macromolecular diffusion through nuclear pore complexes is thought to decrease dramatically beyond ∼40 kD. Using time-resolved fluorescence microscopy and Brownian dynamics simulations, Timney et al. show that this barrier is in fact much softer,

The effect of cell morphology on the permeability of the nuclear envelope to diffusive factors [PDF]
A recent advance in understanding stem cell differentiation is that the cell is able to translate its morphology, i.e., roundish or spread, into a fate decision.

Nuclear pore complexes (NPCs) on the nuclear membrane surface have a crucial function in controlling the movement of small molecules and macromolecules between the cell nucleus and cytoplasm through their intricate core channel resembling a spiderweb ...

Influence of sediment redox conditions on uranium mobilisation during saline intrusion [PDF]
This research was funded by the Natural Environment Research Council (grant NE/C506799/1: Studentship NE/H527116/1).In the UK, several coastal nuclear sites have been identified as vulnerable to future sea level rise.
