HSP70 is required for the proper assembly of pericentriolar material and function of mitotic centrosomes

open access: yesCell Division, 2019
Background At the onset of mitosis, the centrosome expands and matures, acquiring enhanced activities for microtubule nucleation and assembly of a functional bipolar mitotic spindle.

A Balance between Nuclear and Cytoplasmic Volumes Controls Spindle Length. [PDF]

open access: yesPLoS ONE, 2016
Proper assembly of the spindle apparatus is crucially important for faithful chromosome segregation during anaphase. Thanks to the effort over the last decades, we have very detailed information about many events leading to spindle assembly and ...

Relocation of Aurora B from centromeres to the central spindle at the metaphase to anaphase transition requires MKlp2 [PDF]

open access: yes, 2004
Mitotic kinases of the Polo and Aurora families are key regulators of chromosome segregation and cytokinesis. Here, we have investigated the role of MKlp1 and MKlp2, two vertebrate mitotic kinesins essential for cytokinesis, in the spatial regulation of ...

Meiosis-specific stable binding of augmin to acentrosomal spindle poles promotes biased microtubule assembly in oocytes.

open access: yesPLoS Genetics, 2013
In the oocytes of many animals including humans, the meiotic spindle assembles without centrosomes. It is still unclear how multiple pathways contribute to spindle microtubule assembly, and whether they are regulated differently in mitosis and meiosis ...

Mitotic spindle assembly around RCC1-coated beads in Xenopus egg extracts. [PDF]

open access: yesPLoS Biology, 2011
During cell division the genetic material on chromosomes is distributed to daughter cells by a dynamic microtubule structure called the mitotic spindle.

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

open access: yesMolecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

RNF20 Regulates Oocyte Meiotic Spindle Assembly by Recruiting TPM3 to Centromeres and Spindle Poles

open access: yesAdvanced Science
Previously a ring finger protein 20 (RNF20) is found to be essential for meiotic recombination and mediates H2B ubiquitination during spermatogenesis. However, its role in meiotic division is still unknown.

An ATM and ATR dependent checkpoint inactivates spindle assembly by targeting CEP63 [PDF]

open access: yes, 2010
The effects of ATM and ATR signalling induced by chromosomal breakage have been described extensively in modulating cell cycle progression up to the onset of mitosis.

The kinesin-12 Kif15 is a processive track-switching tetramer [PDF]

open access: yes, 2014
Kinesin-12 motors are a little studied branch of the kinesin superfamily with the human protein (Kif15) implicated in spindle mechanics and chromosome movement.

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

open access: yesMolecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...
