Chromosomal Instability, Aneuploidy, and Cancer
The link between aneuploidy and cancer has been recognized over a century ago (1). Abnormalities in chromosome copy numbers arise from persistent errors in chromosome segregation during cell division, a process known as chromosomal instability (CIN) (2). CIN is a principal contributor to genetic heterogeneity in cancer (3) and is an important determinant of clinical prognosis and therapeutic re...
متن کاملChromosomal instability and aneuploidy in cancer: from yeast to man.
Aneuploidy is frequently associated with disease and developmental abnormalities. It is also a key characteristic of cancer. Several model systems have been developed to study the role of chromosomal instability and aneuploidy in tumorigenesis. The results are surprisingly complex, with the conditions sometimes promoting and sometimes inhibiting tumour formation. Here, we review the effects of ...
متن کاملRe-replication of a Centromere Induces Chromosomal Instability and Aneuploidy
The faithful inheritance of chromosomes during cell division requires their precise replication and segregation. Numerous mechanisms ensure that each of these fundamental cell cycle events is performed with a high degree of fidelity. The fidelity of chromosomal replication is maintained in part by re-replication controls that ensure there are no more than two copies of every genomic segment to ...
متن کاملReply to Heng: Inborn aneuploidy and chromosomal instability.
It is with great interest that we read the letter by Heng (1), who kindly brought up the interesting topic of nonclonal-chromosome aberrations (NCCAs) in the context of our recent report on the relationship between inborn aneuploidy and chromosome instability (CIN). We fully agree with Heng that NCCAs are better proxies for CIN than clonal-chromosome aberrations (CCAs). In fact, we used the fre...
متن کاملMeiotic-Like Division to a Aneuploidy: Chromosomal Instability (CIN), Cell-Senescence and Cancer
An understanding of cancer cell heterogeneity requires knowledge of mechanisms for somatic cell variation. For plant (galls) and animals alike, such genetic cell differences can arise from mutations, somatic crossing over, segregation mistakes and from certain viral infection. This latter route for some DNAviruses is an early virus-induced change to polyploid cells which is also increasingly be...
