Dominant-Negative Effects of Adult-Onset Huntingtin Mutations Alter the Division of Human Embryonic Stem Cells-Derived Neural Cells. [PDF]
PLoS ONE, 2016 Mutations of the huntingtin protein (HTT) gene underlie both adult-onset and juvenile forms of Huntington's disease (HD). HTT modulates mitotic spindle orientation and cell fate in mouse cortical progenitors from the ventricular zone.

A spindle-like apparatus guides bacterial chromosome segregation [PDF]
Nature Cell Biology, 2010 Until recently, a dedicated mitotic apparatus that segregates newly replicated chromosomes into daughter cells was believed to be unique to eukaryotic cells. Here we demonstrate that the bacterium Caulobacter crescentus segregates its chromosome using a partitioning (Par) apparatus that has surprising similarities to eukaryotic spindles.

Initial Characterization of two novel spindle proteins, CHICA and HURP [PDF]
, 2008 During mitotic spindle assembly, the sister chromatids have to be captured by kinetochore (K) -fibers (bundles of kinetochore microtubules; KMTs) to ensure stable attachment of the chromosomes.

Frontiers in Marine Science, 2021 Fertilized Zhikong scallop (Chlamys farreri) eggs were treated with cytochalasin B (CB 0.5 mg/L) at 14–15 min postfertilization to inhibit first polar body formation.

Evolutionary cell biology of chromosome segregation: insights from trypanosomes [PDF]
Open Biology, 2013 Faithful transmission of genetic material is essential for the survival of all organisms. Eukaryotic chromosome segregation is driven by the kinetochore that assembles onto centromeric DNA to capture spindle microtubules and govern the movement of ...

Microtubule and Actin Cytoskeletal Dynamics in Male Meiotic Cells of Drosophila melanogaster
Cells, 2022 Drosophila dividing spermatocytes offer a highly suitable cell system in which to investigate the coordinated reorganization of microtubule and actin cytoskeleton systems during cell division of animal cells.

Evidence for a role of spindle matrix formation in cell cycle progression by antibody perturbation.
PLoS ONE, 2018 In Drosophila it has recently been demonstrated that a spindle matrix in the form of a membrane-less macromolecular assembly embeds the microtubule-based spindle apparatus.

Natural products as new antimitotic compounds for anticancer drug development
Clinics, 2018 Cell cycle control genes are frequently mutated in cancer cells, which usually display higher rates of proliferation than normal cells. Dysregulated mitosis leads to genomic instability, which contributes to tumor progression and aggressiveness.

iScience, 2021 Summary: Here we identify human Kinesin-5, Kif11/HsEg5, as a cellular target of Zika protease. We show that Zika NS2B-NS3 protease targets several sites within the motor domain of HsEg5 irrespective of motor binding to microtubules.
