Mechanobiology of the mitotic spindle

N Pavin, IM Tolić - Developmental cell, 2021 - cell.com
The mitotic spindle is a microtubule-based assembly that separates the chromosomes
during cell division. As the spindle is basically a mechanical micro machine, the …

Self-organization and forces in the mitotic spindle

N Pavin, IM Tolić - Annual review of biophysics, 2016 - annualreviews.org
At the onset of division, the cell forms a spindle, a precise self-constructed micromachine
composed of microtubules and the associated proteins, which divides the chromosomes …

[HTML][HTML] Kinetochore life histories reveal an Aurora-B-dependent error correction mechanism in anaphase

O Sen, JU Harrison, NJ Burroughs, AD McAinsh - Developmental cell, 2021 - cell.com
Chromosome mis-segregation during mitosis leads to aneuploidy, which is a hallmark of

Mitotic spindle: kinetochore fibers hold on tight to interpolar bundles

IM Tolić - European Biophysics Journal, 2018 - Springer
When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which
separates the duplicated chromosomes. The attachment of microtubules to chromosomes is …

Chromosome size-dependent polar ejection force impairs mammalian mitotic error correction

MK Chong, M Rosas-Salvans, V Tran… - Journal of Cell Biology, 2024 - rupress.org
Accurate chromosome segregation requires sister kinetochores to biorient, attaching to
opposite spindle poles. To this end, the mammalian kinetochore destabilizes incorrect …

Mapping load-bearing in the mammalian spindle reveals local kinetochore fiber anchorage that provides mechanical isolation and redundancy

MW Elting, M Prakash, DB Udy, S Dumont - Current Biology, 2017 - cell.com
Active forces generated at kinetochores move chromosomes, and the dynamic spindle must
robustly anchor kinetochore fibers (k-fibers) to bear this load. The mammalian spindle bears …
