Abnormal Cytokinesis in Cells Deficient in the Breast Cancer Susceptibility Protein BRCA2
Abstract
Germ-line mutations inactivating BRCA2 predispose to cancer. BRCA2-deficient cells exhibit alterations in chromosome number (aneuploidy), as well as structurally aberrant chromosomes. Here, we show that BRCA2 deficiency impairs the completion of cell division by cytokinesis. BRCA2 inactivation in murine embryo fibroblasts (MEFs) and HeLa cells by targeted gene disruption or RNA interference delays and prevents cell cleavage. Impeded cell separation is accompanied by abnormalities in myosin II organization during the late stages in cytokinesis. BRCA2 may have a role in regulating these events, as it localizes to the cytokinetic midbody. Our findings thus link cytokinetic abnormalities to a hereditary cancer syndrome characterized by chromosomal instability and may help to explain why BRCA2-deficient tumors are frequently aneuploid.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
