Chromosomal instability and human cancer.
Genetic instability is a defining feature of human cancer. The main type of genetic instability, chromosomal instability (CIN), enhances the rate of gross chromosomal changes during cell division. CIN is brought about by mutations of CIN genes, i.e. genes that are involved in maintaining the genomic integrity of the cell. A major question in cancer genetics is whether genetic instability is a c...
متن کاملChromosomal 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 کاملEmerging roles of centrosomal amplification and genomic instability in cancer.
The carcinogenic process is multistep in terms of its etiology and multifactor in terms of its evolution. In this context, the temporal accumulation of multiple genetic changes during multistage carcinogenesis that can be mediated at least in part by genomic instability may represent crucial components of tumor cell evolution. Evidence is accumulating indicating a close link between genomic ins...
متن کاملCancer chromosomal instability: therapeutic and diagnostic challenges.
Chromosomal instability (CIN)-which is a high rate of loss or gain of whole or parts of chromosomes-is a characteristic of most human cancers and a cause of tumour aneuploidy and intra-tumour heterogeneity. CIN is associated with poor patient outcome and drug resistance, which could be mediated by evolutionary adaptation fostered by intra-tumour heterogeneity. In this review, we discuss the cli...
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 ...
