Solving the Polyploid Mystery in Health and Disease.

Solving the Polyploid Mystery in Health and Disease. Trends Genet. 2018 Nov 20;: Authors: Gjelsvik KJ, Besen-McNally R, Losick VP Abstract Polyploidy (the more than doubling of a cell's genome) frequently arises during organogenesis, tissue repair, and age-associated diseases. Despite its prevalence, major gaps exist in how polyploid cells emerge and affect tissue function. Studies have begun to elucidate the signals required for polyploid cell growth as well as the advantages and disadvantages of polyploidy in health and disease. This review highlights the recent advances on the role and regulation of polyploidy in Drosophila and vertebrate models. The newly discovered versatility of polyploid cells has the potential to provide alternative strategies to promote tissue growth and repair, while limiting disease and dysfunction.
