When overexpressed, Myc family proteins also cause genomic instability, a hallmark of both transformed and aging cells. Using an <em>in vivo lacZ</em> mutation reporter, we show that overexpression of Myc in <em>Drosophila</em> increases the frequency of large genome rearrangements associated with erroneous repair of DNA double-strand breaks (DSBs). In addition, we find that overexpression of Myc shortens adult lifespan and, conversely, that Myc haploinsufficiency reduces mutation load and extends lifespan. Our data provide the first evidence that Myc may act as a pro-aging factor, possibly through its ability to greatly increase genome instability.</p> 000010370 536__ $$cAG17242 000010370 536__ $$oEinstein Shock Center$$cAG038072$$aPilot grant 000010370 540__ $$a<p>© 2013 Greer et al.</p> <p>This is an open access article distributed under the terms of the <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">Creative Commons Attribution License</a>, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.</p> 000010370 542__ $$fCC BY 000010370 690__ $$aBiological Sciences Division 000010370 691__ $$aHuman Genetics 000010370 7001_ $$aGreer, Christina$$uAlbert Einstein College of Medicine 000010370 7001_ $$aLee, Moonsook$$uAlbert Einstein College of Medicine 000010370 7001_ $$aWesterhof, Maaike$$uAlbert Einstein College of Medicine 000010370 7001_ $$aMilholland, Brandon$$uAlbert Einstein College of Medicine 000010370 7001_ $$aSpokony, Rebecca$$uUniversity of Chicago 000010370 7001_ $$aVijg, Jan$$uAlbert Einstein College of Medicine 000010370 7001_ $$aSecombe, Julie$$uAlbert Einstein College of Medicine 000010370 773__ $$tPLOS ONE 000010370 8564_ $$yArticle$$90ef754e2-3671-4f57-8075-3b3cc290edda$$s1375460$$uhttps://knowledge.uchicago.edu/record/10370/files/journal.pone.0074641.pdf$$ePublic 000010370 8564_ $$ySupporting information$$99be07c0c-4a30-43c5-b867-72201d4db0df$$s2455800$$uhttps://knowledge.uchicago.edu/record/10370/files/journal.pone.0074641.zip$$ePublic 000010370 908__ $$aI agree 000010370 909CO $$ooai:uchicago.tind.io:10370$$pGLOBAL_SET 000010370 983__ $$aArticle
