To distinguish the molecular determinants of aneuploidy stress, we measured the effects of duplicating individual genes in cells with varying chromosome duplications, in wild-type cells and cells sensitized to aneuploidy by deletion of RNA-binding protein Ssd1. We identified gene duplications that are nearly neutral in wild-type euploid cells but significantly deleterious in euploids lacking\n                  <jats:italic>SSD1<\/jats:italic>\n                  or\n                  <jats:italic>SSD1+<\/jats:italic>\n                  aneuploid cells with different chromosome duplications. Several of the most deleterious genes are linked to translation; in contrast, duplication of other translational regulators, including eI5Fa Hyp2, benefit\n                  <jats:italic>ssd1\u0394<\/jats:italic>\n                  aneuploids over controls. Using modeling of aneuploid growth defects, we propose that the deleterious effects of aneuploidy emerge from an interaction between the cumulative burden of many amplified genes on a chromosome and a subset of duplicated genes that become toxic in that context. Our results suggest that the mechanism behind their toxicity is linked to a key vulnerability in translation in aneuploid cells. These findings provide a perspective on the dual impact of individual genes and overall genomic burden, offering new avenues for understanding aneuploidy and its cellular consequences.\n                <\/jats:p>","DOI":"10.1101\/2024.04.15.589582","type":"posted-content","created":{"date-parts":[[2024,4,20]],"date-time":"2024-04-20T23:15:15Z","timestamp":1713654915000},"source":"Crossref","is-referenced-by-count":4,"title":["The response to single-gene duplication implicates translation as a key vulnerability in aneuploid yeast"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2013-4391","authenticated-orcid":false,"given":"H.
