Now, researchers at the Stanford University School of Medicine have found that the basic principles of how genes are controlled are similar in the two species, validating the mouse's utility in clinical research. <\/p>\n However, there are important differences in the details of gene regulation that distinguish us as a species. <\/p>\n \"At the end of the day, a lot of the genes are identical between a mouse and a human, but we would argue how they're regulated is quite different,\" said Michael Snyder, PhD, professor and chair of genetics at Stanford. \"We are interested in what makes a mouse a mouse and a human a human.\" <\/p>\n The research effort, Mouse ENCODE, is meant to complement a project called the Encyclopedia of DNA Elements, or ENCODE, that began in 2003. ENCODE studied specific components in the human genome that guide genes to code for proteins that carry out a cell's function, a process known as gene expression. Surrounding the protein-coding genes are noncoding regulatory elements, molecules that regulate gene expression by attaching proteins, called transcription factors, to specific regions of DNA. <\/p>\n Why mice matter <\/p>\n Mouse ENCODE analyzed more than 100 mouse cell types and tissues to annotate the regulatory elements of the mouse genome and compare them to the regulatory elements in the human genome. Both ENCODE and Mouse ENCODE are funded and coordinated by the National Human Genome Research Institute. Because mice are used as model organisms for many human clinical studies and drug discovery, understanding the similarities and differences can help researchers understand how the results found in mouse studies can translate to humans. <\/p>\n \"The mindset is when you compare things, it helps understand genome annotation,\" said Mark Gerstein, PhD, the Albert L. Williams Professor of Biomedical Informatics at Yale University. \"It's making the mouse a more meaningful model organism.\" Gerstein collaborated on previous ENCODE research but is not part of the Mouse ENCODE consortium, which is composed of researchers from more than 30 institutions. <\/p>\n <\/p>\n Continued here:<\/p>\n Stanford researchers compare mammals' genomes to aid human clinical research<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" PUBLIC RELEASE DATE: 19-Nov-2014 Contact: Krista Conger kristac@stanford.edu<\/a> 650-725-5371 Stanford University Medical Center @sumedicine For years, scientists have considered the laboratory mouse one of the best models for researching disease in humans because of the genetic similarity between the two mammals.
