Protocol for studying topological DNA interactions by purified fission yeast condensin
STAR ProtocolsSummary: To understand the transition from interphase chromatin into well-shaped chromosomes during cell divisions, we need to understand the biochemical activities of the contributing proteins.

Random Chromosome Partitioning in the Polyploid Bacterium Thermus thermophilus HB27
G3: Genes, Genomes, Genetics, 2019 Little is known about chromosome segregation in polyploid prokaryotes. In this study, whether stringent or variable chromosome segregation occurs in polyploid thermophilic bacterium Thermus thermophilus was analyzed.

Bacterial chromosome segregation by the ParABS system [PDF]
Open Biology, 2020 Proper chromosome segregation during cell division is essential in all domains of life. In the majority of bacterial species, faithful chromosome segregation is mediated by the tripartite ParABS system, consisting of an ATPase protein ParA, a CTPase and ...

A Computational Approach to Estimating Nondisjunction Frequency in Saccharomyces cerevisiae. [PDF]
, 2016 Errors segregating homologous chromosomes during meiosis result in aneuploid gametes and are the largest contributing factor to birth defects and spontaneous abortions in humans.

Chromosome Segregation: Seeing Is Believing [PDF]
Current Biology, 2005 For chromosome segregation in mitosis, each centromere directs assembly of a complex, proteinaceous structure - the kinetochore, which connects the chromosome to microtubules of the mitotic spindle. A recent study has provided important new insights into the mechanism by which kinetochores capture spindle microtubules.

Molecular Oncology, EarlyView.Single‐cell transcriptomics of prostate cancer patient‐derived xenografts reveals distinct features of neuroendocrine (NE) subtypes. Tumours with focal NE differentiation (NED) share transcriptional programmes with adenocarcinoma, differing from large and small cell neuroendocrine prostate cancer (NEPC). Our work defines the molecular landscape of NEPC,

Multimodal effects of small molecule ROCK and LIMK inhibitors on mitosis, and their implication as anti-leukemia agents. [PDF]
PLoS ONE, 2014 Accurate chromosome segregation is vital for cell viability. Many cancer cells show chromosome instability (CIN) due to aberrant expression of the genes involved in chromosome segregation.

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]
, 2016 Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

Molecular Oncology, EarlyView.Gao et al. report that circular DNA molecules created as by‐products of V(D)J recombination during lymphocyte maturation (ESCs) can replicate and be retained for much longer than previously thought in healthy cells. In BCP‐ALL cells, increased ESC abundance correlates with a greater chance of relapse likely mediated by their ability to induce genome ...

Evidence of substrate control of Cdk phosphorylation during the budding yeast cell cycle
Cell ReportsSummary: 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.
