The synaptonemal complex protein Zip1 promotes bi-orientation of centromeres at meiosis I. [PDF]
PLoS Genetics, 2009 In meiosis I, homologous chromosomes become paired and then separate from one another to opposite poles of the spindle. In humans, errors in this process are a leading cause of birth defects, mental retardation, and infertility.

Advanced sleep spindle identification with neural networks [PDF]
Scientific Reports 12, 7686 (2022), 2022 Sleep spindles are neurophysiological phenomena that appear to be linked to memory formation and other functions of the central nervous system, and that can be observed in electroencephalographic recordings (EEG) during sleep. Manually identified spindle annotations in EEG recordings suffer from substantial intra- and inter-rater variability, even if ...

Haematologica, 2013 Spindle poison-based therapy is of only limited benefit in acute myeloid leukemia while lymphoblastic leukemia/lymphoma responds well. In this study, we demonstrated that the spindle assembly checkpoint protein BubR1 was down-regulated in the vast ...

Bub1 kinase in the regulation of mitosis
Animal Cells and Systems, 2021 Accurate chromosome segregation is required for cell survival and organismal development. During mitosis, the spindle assembly checkpoint acts as a safeguard to maintain the high fidelity of mitotic chromosome segregation by monitoring the attachment of ...

Cell Division, 2008 During mitosis, correct bipolar chromosome attachment to the mitotic spindle is an essential prerequisite for the equal segregation of chromosomes. The spindle assembly checkpoint can prevent chromosome segregation as long as not all chromosome pairs ...

Toward a systems-level view of mitotic checkpoints [PDF]
Prog Biophys Mol Biol. 2015 Mar;117(2-3):217-24, 2016 Reproduction and natural selection are the key elements of life. In order to reproduce, the genetic material must be doubled, separated and placed into two new daughter cells, each containing a complete set of chromosomes and organelles. In mitosis, transition from one process to the next is guided by intricate surveillance mechanisms, known as the ...

Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]
Proc. Natl. Acad. Sci. 103 16758-16763 (2006), 2006 Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression. This inhibitory signal switches off rapidly once spindle microtubules have attached to all kinetochores.

Spindle assembly checkpoint is sufficient for complete Cdc20 sequestering in mitotic control [PDF]
Comput Struct Biotechnol J. 2015 Apr 9;13:320-8, 2016 The spindle checkpoint assembly (SAC) ensures genome fidelity by temporarily delaying anaphase onset, until all chromosomes are properly attached to the mitotic spindle. The SAC delays mitotic progression by preventing activation of the ubiquitin ligase anaphase-promoting complex (APC/C) or cyclosome; whose activation by Cdc20 is required for sister ...

Modeling potent pathways for APC/C inhibition: pivotal roles for MCC and BubR1 [PDF]
OMICS: A Journal of Integrative Biology. May 2015, 19(5): 294-305, 2016 The highly conserved spindle assembly checkpoint (SAC) ensures that the sister chromatids of the duplicated genome are not separated and distributed to the spindle poles before all chromosomes have been properly linked to the microtubules of the mitotic spindle.
