Kif11-haploinsufficient oocytes reveal spatially differential requirements for chromosome biorientation

open access: yesEMBO Reports
Bipolar spindle assembly and chromosome biorientation are prerequisites for chromosome segregation during cell division. The kinesin motor KIF11 (also widely known as Eg5) drives spindle bipolarization by sliding antiparallel microtubules bidirectionally,

Spo0J and SMC are required for normal chromosome segregation in Staphylococcus aureus

open access: yesMicrobiologyOpen, 2020
Bacterial chromosome segregation is an essential cellular process that is particularly elusive in spherical bacteria such as the opportunistic human pathogen Staphylococcus aureus.

Kinetochore component function in C. elegans oocytes revealed by 4D tracking of holocentric chromosomes

open access: yesNature Communications, 2023
During cell division, chromosome congression to the spindle center, their orientation along the spindle long axis and alignment at the metaphase plate depend on interactions between spindle microtubules and kinetochores, and are pre-requisite for ...

Chromosome segregation in lymphocyte hybrids [PDF]

open access: yesHereditas, 2009
Chromosome segregation was studied in mouse/human and mouse/mouse T-lymphocyte hybrids, and in mouse/human, mouse/rabbit and mouse/rat B-lymphocyte hybrids. Chromosome loss was not random, it was moderate in mouse/mouse and mouse/rat lymphocyte hybrids, but extensive in mouse/human and mouse/rabbit lymphocyte hybrids.

The dynamics of signal amplification by macromolecular assemblies for the control of chromosome segregation [PDF]

open access: yes, 2016
The control of chromosome segregation relies on the spindle assembly checkpoint (SAC), a complex regulatory system that ensures the high fidelity of chromosome segregation in higher organisms by delaying the onset of anaphase until each chromosome is ...

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

open access: yesFEBS Open Bio, EarlyView.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Bacterial Chromosome Organization and Segregation [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2010
Bacterial chromosomes are generally approximately 1000 times longer than the cells in which they reside, and concurrent replication, segregation, and transcription/translation of this crowded mass of DNA poses a challenging organizational problem. Recent advances in cell-imaging technology with subdiffraction resolution have revealed that the bacterial

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Evidence of substrate control of Cdk phosphorylation during the budding yeast cell cycle

open access: yesCell Reports
Summary: A series of sequential events orchestrates cell growth and division, set in motion by cyclin-dependent kinases (Cdks). In the “qualitative model” for Cdk control, order is achieved by cell cycle stage-specific cyclins.

Super-Resolution Mapping of Neuronal Circuitry With an Index-Optimized Clearing Agent

open access: yesCell Reports, 2016
Super-resolution imaging deep inside tissues has been challenging, as it is extremely sensitive to light scattering and spherical aberrations. Here, we report an optimized optical clearing agent for high-resolution fluorescence imaging (SeeDB2).
