E2F activators signal and maintain centrosome amplification in breast cancer cells.
Centrosomes ensure accurate chromosome segregation by directing spindle bipolarity. Loss of centrosome regulation results in centrosome amplification, multipolar mitosis and aneuploidy. Since centrosome amplification is common in premalignant lesions and breast tumors, it is proposed to play a central role in breast tumorigenesis, a hypothesis that remains to be tested. The coordination between...
متن کاملCdk4 and Nek2 Signal Binucleation and Centrosome Amplification in a Her2+ Breast Cancer Model
Centrosome amplification (CA) is a contributor to carcinogenesis, generating aneuploidy, and chromosome instability. Previous work shows that breast adenocarcinomas have a higher frequency of centrosome defects compared to normal breast tissues. Abnormal centrosome phenotypes are found in pre-malignant lesions, suggesting an early role in breast carcinogenesis. However, the role of CA in breast...
متن کاملCentrosome Amplification: A Potential Marker of Breast Cancer Agressiveness
Maintenance of normal breast epithelial cells depends on the balance between mitogen and tumor suppressor signaling pathways. One of the mechanisms responsible for the origin of phenotypic heterogeneity commonly observed in breast tumors is the development of centrosome amplification leading to mitotic spindle abnormalities and consequent chromosomal instability. However, how mitogen and tumor ...
متن کاملThe E2F activators control multiple mitotic regulators and maintain genomic integrity through Sgo1 and BubR1
The E2F1, E2F2, and E2F3a transcriptional activators control proliferation. However, how the E2F activators regulate mitosis to maintain genomic integrity is unclear. Centrosome amplification (CA) and unregulated spindle assembly checkpoint (SAC) are major generators of aneuploidy and chromosome instability (CIN) in cancer. Previously, we showed that overexpression of single E2F activators indu...
متن کاملEstrogen mediates Aurora-A overexpression, centrosome amplification, chromosomal instability, and breast cancer in female ACI rats.
Estrogens play a crucial role in the causation and development of sporadic human breast cancer (BC). Chromosomal instability (CIN) is a defining trait of early human ductal carcinoma in situ (DCIS) and is believed to precipitate breast oncogenesis. We reported earlier that 100% of female ACI (August/Copenhagen/Irish) rats treated with essentially physiological serum levels of 17beta-estradiol l...
