The nucleus of higher eukaryotes contains a number of structures that concentrate specific biomolecules and play distinct roles in nuclear metabolism. In recent years, the molecular mechanisms controlling their formation have been intensive...
Interdependent changes of nuclear lamins, nuclear pore complexes, and ploidy regulate cellular regeneration and stress response in the heart [0.03%]
核纤层、核孔复合体和倍性相互依赖的变化调节心脏细胞再生和应激反应

In adult mammals, many heart muscle cells (cardiomyocytes) are polyploid, do not proliferate (post-mitotic), and, consequently, cannot contribute to heart regeneration. In contrast, fetal and neonatal heart muscle cells are diploid, prolife...
A survey of the specificity and mechanism of 1,6 hexanediol-induced disruption of nuclear transport [0.03%]

Selective transport through the nuclear pore complex (NPC) depends on the dynamic binding of FG-repeat containing nucleoporins, the FG-nups, with each other and with Karyopherins (Kaps). Here, we assessed the specificity and mechanism by wh...
Where and when to start: Regulating DNA replication origin activity in eukaryotic genomes [0.03%]

In eukaryotic genomes, hundreds to thousands of potential start sites of DNA replication named origins are dispersed across each of the linear chromosomes. During S-phase, only a subset of origins is selected in a stochastic manner to assem...
Transcriptional condensates and phase separation: condensing information across scales and mechanisms [0.03%]

Transcription is the fundamental process of gene expression, which in eukaryotes occurs within the complex physicochemical environment of the nucleus. Decades of research have provided extreme detail in the molecular and functional mechanis...
The interplay between viral molecular mimicry and host chromatin dynamics [0.03%]

Molecular mimicry is a commonly used mechanism by viruses to manipulate host cellular machinery and coordinate their life cycles. While histone mimicry is well studied, viruses also employ other mimicry strategies to affect chromatin dynami...

Transcription Factor (TF) condensates are a heterogenous mix of RNA, DNA, and multiple co-factor proteins capable of modulating the transcriptional response of the cell. The dynamic nature and the spatial location of TF-condensates in the 3...

Peripheral heterochromatin positioning depends on nuclear envelope associated proteins and repressive histone modifications. Here we show that overexpression (OE) of Lamin B1 (LmnB1) leads to the redistribution of peripheral heterochromatin...
Differential contributions of nuclear lamina association and genome compartmentalization to gene regulation [0.03%]

Chromatin regions that interact with the nuclear lamina are often heterochromatic, repressed in gene expression, and in the spatial B compartment. However, exceptions to this trend allow us to examine the relative impact of lamin associatio...
