Although mitotic spindles require spatial cues embedded in the cell cortex for proper alignment, the overall cell shape is radically transformed by mitotic cell rounding. Mitotic rounding requires cortical actin re-modelling, which increases cell stiffness and creates space for spindle formation.

We recently analysed a nationwide cohort of 113 491 sera consecutively tested for ANA which was positive in 60 501 (53%).2 Of these, 592 samples with staining for anti-mitotic spindle apparatus (MSA) antigen patterns (NuMA/MSA-1, midbody/MSA-2, CENP-F/MSA-3 and centrosome) were chosen for further analysis. 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 mediated by kinetochores, protein complexes on the chromosome. The spindle is the structure that pulls the chromatids to opposite ends of the cell during the cell division processes of mitosis and meiosis. Once separated, each chromatid becomes a chromosome. Thus, when the cell divides, both daughter cells have complete… When a cell starts to divide, it forms a spindle, a micro-machine made of microtubules, which separates the duplicated chromosomes.

The primary goal of oncology is to destroy rapidly dividing tumor cells, Toxicology Testing and Evaluation. Aneuploidy, also called nondisjunction, is the unequal distribution of chromosomes to Paclitaxel. In Meyler's Side Effects of Abstract. 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 mediated by kinetochores, protein complexes on the chromosome.

Most errors in chromosome attachment activate the spindle assembly checkpoint (SAC), a surveillance mechanism that delays the onset of anaphase until chromosomes have attached to the mitotic spindle in a bipolar fashion. A major target of the SAC is Cdc20, a substrate-binding subunit of the APC/C (anaphase promoting complex/cyclosome).

Full description or abstract : Collection: H: hallmark gene sets: Source publication : Exact source : Related gene sets (show 108 founder gene sets for this hallmark gene set) N the budding yeast Saccharomyces cerevisiae, the mitotic spindle is exemplified by its simplicity and elegance. Mi- crotubules (MTs) are nucleated by the highly organized ar- ray of proteins inserted in a fenestra in the nuclear envelope known as the spindle pole body (SPB, analogous to the centrosome in larger eukaryotes).

The position of this mitotic spindle tells the cell where to divide, allowing each daughter cell to contain its own identical set of DNA. To gain a more detailed view of microtubules in action, researchers designed an experimental system that utilizes an extract of cells from the African clawed frog ( Xenopus laevis ).
