Aneuploidy
Aneuploidy is an abnormal number of chromosomes, and is a type of chromosome abnormality. An extra or missing chromosome is a common cause of genetic disorders (birth defects). Some cancer cells also have abnormal numbers of chromosomes. Aneuploidy occurs during cell division when the chromosomes do not separate properly between the two cells. Chromosome abnormalities occur in 1 of 160 live births. The most common extra chromosomes among live births are 21, 18 and 13.
Different species have different numbers of normal chromosomes and thus the term "aneuploidy" refers to the chromosome number being different for that species.

Exploiting cancer cells' weaknesses
When designing new cancer drugs, biologists often target specific gene mutations found only in cancer cells, or in a subset of cancer cells. A team of MIT biologists is now taking a slightly different approach, ...

Researchers prove key cancer theory
Mayo Clinic researchers have proven the longstanding theory that changes in the number of whole chromosomes -- called aneuploidy -- can cause cancer by eliminating tumor suppressor genes. Their findings, which appear in the ...

A yeast cancer model for mapping cancer genes
Researchers have devised a scheme for identifying genes in yeast that could lead to the identification of new cancer genes in humans. The study is published online this week in the open-access journal PLoS Bi ...
