Gain a Chromosome and Adapt

Online magazine, The Scientist, reports that research on yeast shows that aneuploidy is both a consequence of and an adaptation to stress.

“Gaining or losing a chromosome, a condition known as aneuploidy, is often caused by stress, and is known to have detrimental consequences, including a variety of human diseases. But according to new research in yeast published online today (January 30) in Nature, stress-induced aneuploidy may also help organisms adapt, conferring an adaptive advantage to yeast cells in the face of continued stress.

‘It’s in interesting study,’ said Judith Berman, a molecular geneticist at the University of Minnesota who was not involved in the research. Berman’s own work in Candida albicans  yeast supports the idea that aneuploidy has adaptive functions, she said, and the new study highlights aneuploidy’s underappreciated role in generating genetic and phenotypic diversity.”

About UWF Center on Aging

The Center on Aging at the University of West Florida was established in the Fall of 2010 when the School of Psychological and Behavioral Sciences faculty along with assistance from Sponsored Research submitted a grant to the State University System Board of Governors in support of aging initiatives for Northwest Florida. Its mission is to improve the quality of life of aging adults through the application of science to address challenges associated with aging and to promote healthy aging, with an emphasis on prevention. This will be accomplished through inter-disciplinary and inter-professional efforts of basic and applied research, consultation, and partnerships with community agencies. Education and training, direct services to the aging population, and public awareness and understanding of the contributions and needs of elders will be primary objectives.
