title: Link between aneuploidy and chromosome instability.
abstract: Aneuploidy is widely acknowledged as a leading cause of miscarriage and birth defects in humans, and is generally known to be deleterious to the survival of individual cells. However, aneuploidy is also ubiquitous in cancer and is found to arise as an adaptive response in certain contexts. This dichotomy of aneuploidy has attracted the interest of researchers for over a century, but many studies have reached conflicting conclusions. The emergence of new technology has allowed scientists to revisit the aneuploidy problem and has fueled a number of recent studies aimed at understanding the effects of aneuploidy on cell physiology. Here, we review these studies, in light of previous observations and knowledge, specifically focusing on the effects of aneuploidy on cellular homeostasis, chromosome stability, and adaptation.
