Chromatin Shapes the Mitotic Spindle
In animal and plant cells, mitotic chromatin locally generates microtubules that self-organize into a mitotic spindle, and its dimensions and bipolar symmetry are essential for accurate chromosome segregation. By immobilizing microscopic chromatin-coated beads on slide surfaces using a microprinting technique, we have examined the effect of chromatin on the dimensions and symmetry of spindles i...
متن کاملMitotic checkpoint control and chromatin remodeling.
In order to maintain chromosomal stability during cell division, eukaryotic cells have evolved a number of surveillance mechanisms termed checkpoints. These checkpoints monitor the completion of essential molecular and cellular processes of one stage before entering another. The spindle checkpoint watches the bi-orientation attachment of spindle microtubules to all condensed chromosomes before ...
متن کاملNudC Deacetylation Regulates Mitotic Progression
Mitosis is largely driven by posttranslational modifications of proteins. Recent studies suggest that protein acetylation is prevalent in mitosis, but how protein acetylation/deacetylation regulates mitotic progression remains unclear. Nuclear distribution protein C (NudC), a conserved protein that regulates cell division, was previously shown to be acetylated. We found that NudC acetylation wa...
متن کاملNew Mitotic Regulators Released from Chromatin
Faithful action of the mitotic spindle segregates duplicated chromosomes into daughter cells. Perturbations of this process result in chromosome mis-segregation, leading to chromosomal instability and cancer development. Chromosomes are not simply passengers segregated by spindle microtubules but rather play a major active role in spindle assembly. The GTP bound form of the Ran GTPase (RanGTP),...
متن کاملMitotic Block of Human Blood Cells by Vinca herbacea, Catharanthus roseus and Colchicine Alkaloids
Catharanthus roseus (L.) G.Don is a plant which produces anticancer and anti-mitotic indole alkaloids. Colchicine is an anti-mitotic drug. Anti-mitotic effects of Vinca herbacea Waldst. & Kit. indole alkaloids is unknown. The study were evaluated the antimitotic effect of alkaloids of V. herbacea, Catharanthus roseus andcolchicineon mitosis and microtubule arrangement of human blood cells. In t...
