Nonthermal fluctuations of the mitotic spindle [PDF]

open access: yesSoft Matter, 2015
Quantitative measurements of fluctuations in the nucleus of mitotic cells can be fully accounted for by a simple model of de-correlated active force fluctuations in a viscoelastic medium dominated by a solution of DNA.

Chromatin Shapes the Mitotic Spindle [PDF]

open access: yesJournal of End-to-End-testing, 2009
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 ...

Nuclear targeted Saccharomyces cerevisiae asparagine synthetases associate with the mitotic spindle regardless of their enzymatic activity.

open access: yesPLoS ONE, 2020
Recently, human asparagine synthetase has been found to be associated with the mitotic spindle. However, this event cannot be seen in yeast because yeast takes a different cell division process via closed mitosis (there is no nuclear envelope breakdown ...

A cell cycle timer for asymmetric spindle positioning.

open access: yesPLoS Biology, 2009
The displacement of the mitotic spindle to one side of a cell is important for many cells to divide unequally. While recent progress has begun to unveil some of the molecular mechanisms of mitotic spindle displacement, far less is known about how spindle

New mitotic regulators released from chromatin

open access: yesFrontiers in Oncology, 2013
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.

The mitotic spindle checkpoint [PDF]

open access: yesCurrent Biology, 2001
Fantastic progress has been made in understanding the spindle checkpoint, the guardian of balanced chromosome segregation. However, several basic questions and many details remain to be worked out. In the meantime, the use of chimeric fluorescent proteins and ever better imaging technology has enhanced the stunning videos of mitosis made today ...

Characterization of ring-like F-actin structure as a mechanical partner for spindle positioning in mitosis. [PDF]

open access: yesPLoS ONE, 2014
Proper spindle positioning and orientation are essential for accurate mitosis which requires dynamic interactions between microtubule and actin filament (F-actin).

Fission yeast cells undergo nuclear division in the absence of spindle microtubules. [PDF]

open access: yesPLoS Biology, 2010
Mitosis in eukaryotic cells employs spindle microtubules to drive accurate chromosome segregation at cell division. Cells lacking spindle microtubules arrest in mitosis due to a spindle checkpoint that delays mitotic progression until all chromosomes ...

Meiotic cells escape prolonged spindle checkpoint activity through kinetochore silencing and slippage.

open access: yesPLoS Genetics, 2023
To prevent chromosome mis-segregation, a surveillance mechanism known as the spindle checkpoint delays the cell cycle if kinetochores are not attached to spindle microtubules, allowing the cell additional time to correct improper attachments.

Mitotic spindle proteomics in Chinese hamster ovary cells.

open access: yesPLoS ONE, 2011
Mitosis is a fundamental process in the development of all organisms. The mitotic spindle guides the cell through mitosis as it mediates the segregation of chromosomes, the orientation of the cleavage furrow, and the progression of cell division.
