   Author : Emil Nilsson; Helgi Schiöth; Christian Benedict; Samantha Brooks; Charlotte Ling; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The most studied form of epigenetics is DNA methylation and several studies have investigated the link between the methylome and body weight. In paper I we analyzed the methylation profile of whole blood in 46 subjects measured with Illumina 27K chip. We provide evidence that obesity influences age driven epigenetic changes. READ MORE
