The role of over 300 mouse genes have been analysed by scientists across Europe in a major initiative to try to understand the part they play in disease and biology.

Since mice share over 90 per cent of their genes with humans they represent one of the best organisms to help us understand human genetics. The European Mouse Disease Clinic (EUMODIC), a consortium that includes the Wellcome Trust Sanger Institute, brought together scientists from across Europe to investigate the functions of 320 genes in mice. These studies involved generating individual mouse lines in which a single gene had been turned off. Over half of these genes had no previously known function and the remaining genes were poorly understood.

Over 80 per cent of the mouse lines assessed had a characteristic that provided a clue to what the missing gene’s role might be. If the mouse failed a hearing test, for example, the suggestion was that the missing gene might have a role in hearing. In total, they carried out over 20 different tests capturing data on 400 characteristics for each mouse line.

“The standardised practices that have been developed through this research allow multiple centres to work in concert to generate robust, reproducible data. In the long term, this streamlined approach and the availability of the data from these studies will significantly reduce the number of animals used in research.”

The researchers classified 94 genes out of the 320 studied that were linked to disease into three categories: bone and skeleton, metabolism, and neurological and behavioural disorders.

One of the genes studied, Elmod1, belongs to a large group of genes active in the brain for which no information on function is available. This work revealed that mice with a faulty Elmod1 gene had lower blood glucose levels and lower body weight. It also revealed that this gene was involved in muscle function and the animals had a lower grip strength.

In order to study gene function, the EUMODIC consortium produced mouse lines which each had a single gene turned off. These mouse lines were then analysed in mouse clinics, where each mouse was assessed by a series of tests and investigations, allowing the researchers to establish the functions of the missing genes.

EUMODIC was the first step towards the creation of a database of mouse gene functions, a vision now being realised by the International Mouse Phenotyping Consortium (IMPC).

The IMPC incorporates centres from across the globe with the aim of uncovering the functions of all 20,000 genes in the mouse genome. IMPC builds on the groundwork and achievements of EUMODIC in establishing the procedures and processes to identify and catalogue the functions of genes.

“EUMODIC leaves a powerful legacy that will live on in the IMPC and the data and resources it has provided for scientists. EUMODIC and IMPC will be truly transformative for medical research by revealing the roles that different genes play in disease.”

This was the first time such a project has been attempted on this scale with multiple centres cooperating together from different countries. The consortium had to establish new standardised procedures to generate and assess the mouse lines and a central European database to store all the data.

The aim of the project was to understand more about genes we currently know very little about, and open up new avenues for research into the genetics of human disease. All the findings have been made publically available, allowing other scientists to use them in their own research.

Overall the Sanger Institute has generated and extensively phenotyped over 1,000 mouse lines, making these data available to the community.

    EUMODIC, was established in 2007, and was the first genetics project of its kind bringing together mouse genetics centres from across Europe to work together to study the role of hundreds of genes. It revealed the traits of over 300 genes and set standards and procedures for a larger international effort to investigate the functions of all 20,000 genes in the mouse.

  • MRC Harwell

    MRC Harwell is located on the Harwell research campus. MRC Harwell is an integrated centre for mouse genetics research, generating and studying mouse models of diseases from the earliest stages of development to ageing. MRC Harwell is a key player in the International Mouse Phenotyping Consortium, IMPC and runs the Harwell Ageing Screen, a large-scale project to study the genetics of age-related disease. All data from these projects are made available to the wider scientific community via the IMPC portal and MouseBook .The research programmes range from neurobehavioural genetics, genetics of deafness, disorders of sex development, cilia development and disease and the genetics of type 2 diabetes.

  • Medical Research Council

    The Medical Research Council is at the forefront of scientific discovery to improve human health. Founded in 1913 to tackle tuberculosis, the MRC now invests taxpayers' money in some of the best medical research in the world across every area of health. Thirty-one MRC-funded researchers have won Nobel prizes in a wide range of disciplines, and MRC scientists have been behind such diverse discoveries as vitamins, the structure of DNA and the link between smoking and cancer, as well as achievements such as pioneering the use of randomised controlled trials, the invention of MRI scanning, and the development of a group of antibodies used in the making of some of the most successful drugs ever developed. Today, MRC-funded scientists tackle some of the greatest health problems facing humanity in the 21st century, from the rising tide of chronic diseases associated with ageing to the threats posed by rapidly mutating micro-organisms.
