Comparison of hom(oe)ologous chromosome segments in the highly polyploid interspecific genome of sugarcane [PDF]

, 2013
Modern sugarcane cultivars (Saccharum spp.) present one of the most complex crop genome studied to date, mainly due to a very high degree of polyploidy (2n = 12x = 120), and an interspecific origin from two autopolyploid species, namely S.

Mammalian telomeres and their partnership with lamins [PDF]

, 2016
Chromosome ends are complex structures, which require a panel of factors for their elongation, replication, and protection. We describe here the mechanics of mammalian telomeres, dynamics and maintainance in relation to lamins.

Entropic organization of interphase chromosomes [PDF]

Journal of Cell Biology, 2009
Chromosomes are not distributed randomly in nuclei. Appropriate positioning can activate (or repress) genes by bringing them closer to active (or inactive) compartments like euchromatin (or heterochromatin), and this is usually assumed to be driven by specific local forces (e.g., involving H bonds between nucleosomes or between nucleosomes and the ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Regulated TRESLIN-MTBP loading governs initiation zones and replication timing in human DNA replication

Nature Communications
Replication origins in human cells form clusters ranging from tens to hundreds of kilobases called initiation zones (IZs), typically located in intergenic regions between active genes.

Conserved Genome Organization and Core Transcriptome of the Lactobacillus acidophilus Complex

Frontiers in Microbiology, 2018
The Lactobacillus genus encompasses a genetically and functionally diverse group of species, and contains many strains widely formulated in the human food supply chain as probiotics and starter cultures. Within this genetically expansive group, there are

The condensin complex is required for proper spindle assembly and chromosome segregation in Xenopus egg extracts. [PDF]

, 2003
Chromosome condensation is required for the physical resolution and segregation of sister chromatids during cell division, but the precise role of higher order chromatin structure in mitotic chromosome functions is unclear.

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma

Molecular Oncology, EarlyView.
The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

Folding and cytoplasm viscoelasticity contribute jointly to chromosome dynamics

, 2017
The chromosome is a key player of cell physiology, and its dynamics provides valuable information about its physical organization. In both prokaryotes and eukaryotes, the short-time motion of chromosomal loci has been described as a Rouse model in a ...

Evidence for a nuclear compartment of transcription and splicing located at chromosome domain boundaries [PDF]

, 1993
The nuclear topography of splicing snRNPs, mRNA transcripts and chromosome domains in various mammalian cell types are described. The visualization of splicing snRNPs, defined by the Sm antigen, and coiled bodies, revealed distinctly different ...
