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.

Evaluating the involvement of autolysosomes in the nuclear translocation of fluorescent proteins

FEBS Open Bio, EarlyView.
Endogenously expressed fluorescent proteins can be degraded by autophagy and transported to cell nuclei via the nuclear pore complex. But in some cell lines, for example, HeLa cells which are positive for immunoreactivity of a receptor ligand, such as UCN I, in cell nuclei, fusion of autolysosome with the nuclear envelope is involved in the nuclear ...

Nuclear envelope transmembrane proteins in differentiation systems [PDF]

, 2012
Historically, our perception of the nuclear envelope has evolved from a simple barrier isolating the genome from the rest of a cell to a complex system that regulates functions including transcription, splicing, DNA replication and repair and ...

An ESCRT-LEM protein surveillance system is poised to directly monitor the nuclear envelope and nuclear transport system

eLife, 2019
The integrity of the nuclear membranes coupled to the selective barrier of nuclear pore complexes (NPCs) are essential for the segregation of nucleoplasm and cytoplasm.

Infection-induced chromatin modifications facilitate translocation of herpes simplex virus capsids to the inner nuclear membrane.

PLoS Pathogens, 2021
Herpes simplex virus capsids are assembled and packaged in the nucleus and move by diffusion through the nucleoplasm to the nuclear envelope for egress.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

VPS4B orchestrates response to nuclear envelope stress by regulating ESCRT-III dynamics in glioblastoma

Nucleus
The Nuclear envelope (NE) is frequently challenged by mechanical stimuli involving cells passing through a tight space and such stress is known as “NE stress.” Various factors that cooperate to repair the NE have been identified, including endosomal ...

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

Biochemistry 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 ...

Threonine 348 regulates the subcellular localization of PTEN

FEBS Open Bio, EarlyView.
Thr348 in the C2 domain is a key contributor to PTEN subcellular localization. The PTEN350 fragment and PTENA4 accumulated in the nucleus, whereas PTENK13R,A4 predominantly localized to the plasma membrane. In contrast, substitution of Thr348 with Asp (T348D) disrupted these characteristic localization patterns, resulting in predominant cytoplasmic ...
