Aneuploidy
The terms 'haploid' and 'diploid' that describe single (n) and double (2n) chromosome sets in cells were coined by the Polish-German botanist Eduard Strasburger and originate from the Greek terms haplóos meaning 'single' and diplóos meaning 'double'. The term 'ploidy' was subsequently derived to describe the total chromosome content of cells. Consequently, the term 'euploid' refers to a chromos...
متن کاملTranscriptional consequences of aneuploidy.
Aneuploidy, or an aberrant karyotype, results in developmental disabilities and has been implicated in tumorigenesis. However, the causes of aneuploidy-induced phenotypes and the consequences of aneuploidy on cell physiology remain poorly understood. We have performed a metaanalysis on gene expression data from aneuploid cells in diverse organisms, including yeast, plants, mice, and humans. We ...
متن کاملScreening for Fetal Aneuploidy
Aneuploidy is defined as having one or more extra or missing chromosomes, leading to an unbalanced chromosome number in a cell. Because each chromosome consists of hundreds of genes, the loss or gain of large chromosomal segments disrupts significant amounts of genetic material and often results in a nonviable pregnancy or offspring that may not survive after birth. In the case of a surviving n...
متن کاملDoes aneuploidy cause cancer?
Aneuploidy has been recognized as a common characteristic of cancer cells for >100 years. Aneuploidy frequently results from errors of the mitotic checkpoint, the major cell cycle control mechanism that acts to prevent chromosome missegregation. The mitotic checkpoint is often compromised in human tumors, although not as a result of germline mutations in genes encoding checkpoint proteins. Less...
متن کاملHow to Survive Aneuploidy
Aneuploidy, or an abnormal number of chromosomes, adversely affects cell growth, but it is also linked with cancer and tumorigenesis. Now, Torres et al. (2010) help to resolve this paradox by demonstrating that aneuploid yeast cells can evolve mutations in the proteasome protein degradation pathway that alleviate imbalances in protein production and increase the cell's proliferative capacities.
