The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn't, however, clarify why older fathers pass on more mutations than younger ones do. The mechanisms that might underlie these well-documented trends have long remained a mystery. Now, a new study in the journal Nature Ecology &amp; Evolution by <keyword id="120084" type="General" weightage="50" keywordseo="rockefeller-university" source="Orion">Rockefeller University</keyword> scientists describes why older male fruit flies are more likely to pass mutations onto their offspring, potentially shining a light on inherited-disease risk in humans. Researchers in Li <keyword id="276396" type="General" weightage="80" keywordseo="zhao" source="Orion">Zhao</keyword>'s lab studied mutations that occur during the production of sperm from germline cells, known as spermatogenesis. They found that mutations are common in the testes of both young and old fruit flies, but more abundant in older flies from the outset. Moreover, many of these mutations seem to be removed in younger fruit flies during spermatogenesis by the body's genomic repair mechanisms -- but they fail to be fixed in the testes of older flies. "We were trying to test whether the older germline is less efficient at mutation repair, or whether the older germline just starts out more mutated," says first author <keyword id="16053850" type="General" weightage="80" keywordseo="evan-witt" source="Orion">Evan Witt</keyword>, a former graduate student in the lab and now a computational biologist at Biomarin Pharmaceuticals. "Our results indicate that it's actually both. At every stage of spermatogenesis, there are more mutations per <keyword id="130094" type="General" weightage="50" keywordseo="rna" source="Orion">RNA</keyword> molecule in older flies than in younger flies." Genomes keep themselves tidy using a handful of repair mechanisms. When it comes to testes, they have to work overtime; testes have the highest rate of gene expression of any organ. Moreover, genes that are highly expressed in spermatogenesis tend to have fewer mutations than those that are not. This sounds counterintuitive, but it makes sense: One theory to explain why the testes express so many genes holds that it might be a sort of genomic surveillance mechanism -- a way to reveal, and then weed out, problematic mutations. But when it comes to older sperm, the researchers found, the weed-whacker apparently sputters out. Previous research suggests that a faulty transcription-coupled repair mechanism, which only fixes transcribed genes, could be to blame. The next step is to expand the analysis to more age groups of flies and test whether or not this transcription repair mechanism can occur -- and if it does, identify the pathways responsible, Witt says. "What genes," he wonders, "are really driving the difference between old and young flies in terms of mutation repair?" Because fruit flies have a high reproductive rate, investigating their mutation patterns can offer new insights into the effect of new mutations in human health and evolution, says Zhao. Witt adds, "It's largely unknown whether a more mutated male germline is more or less fertile than a less mutated one. There's not been very much research on it except for at a population level. And if people inherit more mutations from aging fathers, that increases the odds of de novo genetic disorders or certain types of cancers."

Older fathers pass on more genetic mutations to their offspring, says a study by Rockefeller University

<div class="KonaFilter image-container display-table float_right"><div><div class="image on-image">AP Photo/Evan VucciWhite House Press Secretary Sarah Huckabee Sanders.</div></div></div>White House press secretary Sarah Huckabee Sanders doubled down on comments she made earlier this week about former FBI Director James Comey having potentially broken the law when he leaked notes memorializing his conversations with the president to a friend, who then gave them to The New York Times.Asked on Wednesday "what specifically" Sanders was referring to when she said on Tuesday that some of Comey's conduct could have been illegal, Sanders replied that "the memos that Comey leaked were created on an FBI computer while he was the director."A White House official told Business Insider on Tuesday that "we don't know" whether the information in the memo Comey gave to his friend was classified (the friend, Daniel Richman, <a href="http://www.politico.com/story/2017/07/10/james-comey-memos-retroactively-classified-240362">has insisted it wasn't</a>). But Sanders said on Wednesday that "leaking FBI memos on a sensitive case" is illegal "regardless of classification.""He claims they were private property, but they clearly followed the protocol of an official FBI document," Sanders said. "Leaking FBI memos on a sensitive case, regardless of classification, violates federal laws, including the Privacy Act, a standard FBI employment agreement, and a non-disclosure agreement all FBI employees must sign. I think that's pretty clean, and clear, that that would be a violation."Former federal prosecutor Renato Mariotti told Business Insider on Wednesday that Sanders' comments were not as straightforward as they seemed."It is very hard for me to see what the Privacy Act has to do with the memos written by Comey," Mariotti said. "The other two things she mentioned were the FBI standard employment agreement and non disclosure agreement. Those are contracts, not laws. Could they sue Comey for breach of contract? Maybe... but it would be a suit for money damages, not a FBI criminal investigation."Asked what she would "like to see happen," Sanders replied: "That's not up for me to decide... the Department of Justice has to look into any allegations of whether something is illegal or not."Sanders sparked controversy on Tuesday when she said the Justice Department "should certainly look at" prosecuting Comey, whom she accused of leaking "privileged information" and giving "false testimony" to Congress.Asked for comment, a White House official told Business Insider on Tuesday that Sanders was simply referring questions about the legality of Comey's actions to the DOJ. Still, many legal and national security experts found Sanders' remarks disconcerting and inappropriate."It's hard to overstate how egregious Sanders' conduct is here," said Susan Hennessey, a former National Security Agency attorney. "It's an outright assault on an independent DOJ."Democratic Sen. Sheldon Whitehouse weighed in on Wednesday morning on Twitter: "FBI Dir Wray said there had not been a 'whiff' of White House pressure; he just got his 1st whiff." His <a href="https://twitter.com/SenWhitehouse/status/907966256762023938" target="_blank" rel="noopener noreferrer">tweet was in response</a> to Sanders' DOJ comments. "Someone in WH needs to tell them to knock it off," he said.Matthew Miller, who served as a DOJ spokesman under President Barack Obama, echoed Whitehouse's sentiment on Wednesday afternoon."Where is the [Attorney General]?" Miller wrote. "Eric Holder would've been on phone immediately telling the WH to cut this crap out."Ben Wittes, a friend of Comey who is the editor-in-chief of Lawfare, a blog dedicated to national security issues, <a href="http://www.businessinsider.com/james-comey-trump-white-house-russia-2017-9" target="_blank" rel="noopener noreferrer">told Business Insider on Tuesday</a> that "Jim Comey would not have mishandled classified information.""In a battle between Comey and the president over any matter of credibility, I would think the question answers itself as to which one I believe," Wittes said. "And I can't imagine that Jim is spending any time worried about any investigation of his conduct, whereas I think the president is clearly very concerned about investigations of his conduct." <div class="margin-top"> <h3>NOW WATCH: <a href="http://www.businessinsider.com/russia-building-bridge-to-crimea-2017-8">Putin's controversial bridge to connect Russia to annexed Crimea will be the longest in Russian history</a></h3> <div> </div> </div>
