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 ...

Oxidative Stress Overrides the Spindle Checkpoint [PDF]
Aneuploidy, an abnormal chromosome set, can ensue from failure of the spindle checkpoint, the safeguard mechanism that halts anaphase onset until mitotic spindle assembly. Inefficiency of cells to maintain the normal chromosome set across cell generations has been linked to tumorigenesis and senescence.

The Spindle Assembly Checkpoint Is Required for Hematopoietic Progenitor Cell Engraftment
Summary: The spindle assembly checkpoint plays a pivotal role in preventing aneuploidy and transformation. Many studies demonstrate impairment of this checkpoint in cancer cells.

Loss of function of the Cik1/Kar3 motor complex results in chromosomes with syntelic attachment that are sensed by the tension checkpoint. [PDF]
The attachment of sister kinetochores by microtubules emanating from opposite spindle poles establishes chromosome bipolar attachment, which generates tension on chromosomes and is essential for sister-chromatid segregation.

Smurf2 as a novel mitotic regulator: From the spindle assembly checkpoint to tumorigenesis
The execution of the mitotic program with high fidelity is dependent upon precise spatiotemporal regulation of posttranslational protein modifications.

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.

Some assembly required: Redefining the mitotic checkpoint
The spindle assembly checkpoint (also known as the spindle or mitotic checkpoint) is a surveillance system that ensures fidelity of chromosome segregation.

Running on a treadmill: dynamic inhibition of APC/C by the spindle checkpoint
During mitosis, the genome duplicated during S-phase is synchronously and accurately segregated to the two daughter cells. The spindle checkpoint prevents premature sister-chromatid separation and mitotic exit.

Kinase Signaling in the Spindle Checkpoint [PDF]
The spindle checkpoint is a cell cycle surveillance system that ensures the fidelity of chromosome segregation. In mitosis, it elicits the "wait anaphase" signal to inhibit the anaphase-promoting complex or cyclosome until all chromosomes achieve bipolar microtubule attachment and align at the metaphase plate. Because a single kinetochore unattached to

Orchestration of the spindle assembly checkpoint by CDK1‐cyclin B1
In mitosis, the spindle assembly checkpoint (SAC) monitors the formation of microtubule‐kinetochore attachments during capture of chromosomes by the mitotic spindle. Spindle assembly is complete once there are no longer any unattached kinetochores. Here,
