title: [Correlations of centrosome abnormality and genomic instability to tumor].
abstract: Genomic instability, including whole chromosome loss or gain, ploidy change, and a variety of chromosome aberration, is a characteristic of tumor cells. Centrosome abnormality is also found in several kinds of tumors. Abnormal centrosome can cause multipolar spindle formation, chromosome mis-segregation, and unequal distribution, and finally leads to cancers. Therefore, abnormal centrosome is common in tumor cells, and centrosome amplification is probably an early event in the origination and development of cancer.
