Spindle Assembly: Two Spindles for Two Genomes in a Mammalian Zygote [PDF]
A single bipolar spindle was thought to form around both parental genomes in zygotes initiating the first division. A recent study challenges this predominant view by showing that two independent spindles assemble to prevent parental genome mixing in mouse zygotes.

Spindle assembly checkpoint silencing and beyond [PDF]
The Spindle Assembly Checkpoint (SAC) prevents anaphase onset in the absence of kinetochore-microtubule attachment, ensuring that cells with unattached kinetochores do not proceed into anaphase.

Attachment and tension in the spindle assembly checkpoint [PDF]
Faithful transmission of chromosomes during mitosis is ensured by the spindle assembly checkpoint. This molecular safeguard examines whether prerequisites for chromosome segregation have been satisfied and thereby determines whether to execute or to delay chromosome segregation.

Mechanisms of spindle assembly and size control [PDF]
AbstractThe spindle is crucial for cell division by allowing the faithful segregation of replicated chromosomes to daughter cells. Proper segregation is ensured only if microtubules (MTs) and hundreds of other associated factors interact to assemble this complex structure with the appropriate architecture and size.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

On the assembly of the mitotic spindle, bistability and hysteresis
AbstractDuring cell division, the transition from interphase to mitosis is dictated by activation of the cyclin B-cdk1 (Cdk1) complex, master mitotic kinase. During interphase, Cdk1 accumulates in an inactive state (pre-Cdk1). When Cdk1 overcomes a certain threshold of activity upon initial activation of pre-Cdk1, then the stockpiled pre-Cdk1 is ...
