Sarkar, senior author of the study and director of the Endocrine Program in the Department of Animal Sciences at Rutgers University-New Brunswick. &#8220;This may help explain why alcoholism is such a powerful addiction, and may one day contribute to new ways to treat alcoholism or help prevent at-risk people from becoming addicted.&#8221;<\/p>\n<p>In 2016, more than 3 million people died from the harmful use of alcohol, according a World Health Organization report. That is 5 percent of all global deaths. More than three-quarters of alcohol-caused deaths were among men. The harmful use of alcohol also caused 5.1 percent of the worldwide toll of disease and injuries.<\/p>\n<p>Scientists at Rutgers and Yale University School of Medicine focused on two genes implicated in the control of drinking behavior: <strong>PER2<\/strong>, which influences the body&#8217;s biological clock, and <strong>POMC<\/strong>, which regulates our stress-response system.<\/p>\n<p>By comparing groups of moderate, binge and heavy drinkers, the researchers found that the <strong>two genes had changed in the binge and heavy drinkers through an alcohol-influenced gene modification process called methylation<\/strong>. The binge and heavy drinkers also showed <strong>reductions in gene expression<\/strong>, or the rate at which these genes create proteins. These changes increased with greater alcohol intake.<\/p>\n<p>Additionally, in an experiment, the drinkers viewed stress-related, neutral or alcohol-related images. They also were shown containers of beer and subsequently tasted beer, and their motivation to drink was evaluated. The result: <strong>alcohol-fueled changes in the genes of binge and heavy drinkers were associated with a greater desire for alcohol<\/strong>.<\/p>\n<p>The findings may eventually help researchers identify biomarkers &#8212; measurable indicators such as proteins or modified genes &#8212; that could predict an individual&#8217;s risk for binge or heavy drinking, said Sarkar, who works in the School of Environmental and Biological Sciences.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the Rutgers University press release: Binge and heavy drinking may trigger a long-lasting genetic change, resulting in an even greater craving for alcohol, according to a Rutgers-led study in&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2019\/03\/study-suggests-heavy-drinking-may-change-dna-leading-to-increased-craving-for-alcohol\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[350,356],"tags":[21,185,245,490,234,305],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/28063"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=28063"}],"version-history":[{"count":2,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/28063\/revisions"}],"predecessor-version":[{"id":28260,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/28063\/revisions\/28260"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=28063"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=28063"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=28063"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
