Eumorphia Phenotype screens for mice Developing an integrated platform :  Eumorphia Phenotype screens for mice Developing an integrated platform Slide2:  EUMORPHIA - the consortium MRC Mammalian Genetics Unit, UK IGBMC, Strasbourg, France MRC Human Genetics Unit, UK MRC Functional Genetics, UK ANIMAGE, Lyon, France CNG/CNRS Paris, France GSF, Munich, Germany GBF, Braunschwieg, Germany NKI, Amsterdam, Netherlands EMBL Monterotondo, Italy CNR-IBC, Monterotondo, Italy Karolinska, Stockholm, Sweden UNIL-IBA, Lausanne, Switzerland UNIGE, Geneva, Switzerland Sanger Institute, Hinxton, UK CNIO, Madrid, Spain Univ. Manchester, UK 18 centres across Europe Importance of standardisation:  Importance of standardisation Better reproducibility of test outcome Better comparability of test outcome Sharing of phenome results Reduction in the number of mice used in research EUMORPHIA:  EUMORPHIA Phenotyping Working groups to develop and standardise primary and secondary phenotyping protocols for all body systems To develop them in collaboration with other centres throughout the world and in consultation with clinicians, human geneticists, physiologists and informaticians Slide5:  Phenotyping - Workpackages Standardisation - animal handling Clinical Chemistry/Haematology Renal systems Central, peripheral nervous system, muscle Behaviour and cognition Imaging Necropsy, pathology, histology First-line phenotyping Cardiovascular Hormonal/metabolic Allergy and infection Sensory systems Pulmonary Cancer Bone, Cartilage Expression analysis European Mouse Phenotyping Resource for Standardised Screens - EMPReSS What is EMPReSS?:  What is EMPReSS? European Mouse Phenotyping Resource for Standardised Screens The EMPReSS provides a platform for the systematic and standardised primary characterisation of mouse mutant models It is a comprehensive database of validated SOPs for systematic screens and tests that allows us to describe the phenotype of a mouse Slide7:  www.eumorphia.org How was EMPReSS constructed?:  How was EMPReSS constructed? The SOPs are categorised according to the experience required and the amount of specialised equipment. The primary tests are divided into: Primary - for those tests that are simple to apply and require little specialist equipment Primary extended - which give further information on the phenotype, but require more specialised skills or equipment. Slide9:  Working groups established SOPs discussed and drafted Validation between centres Discussion of validation results Revision of SOPs Revalidation between centres Additional validation between centres Review of SOPs by EMPReSS resource team Review and sign-off by Eumorphia scientist outside working group Slide10:  BALB/cByJ (+ BALB/cAnN) AnN ENU mutagenesis at Harwell C57BL/6J (+ C57BL/6N) C3H/HeBFeJ (+ C3H/HeN) FeJ ENU mutagenesis at GSF/HeN at Harwell 129/SvPas (+ 129S6/SvEvTac) Inbred strains for validation EMPReSS to date:  EMPReSS to date WP groups established March 2003 All relevant WPs have contributed A total of 161 SOPs, both primary and primary extended, have been submitted and accepted by EMPReSS along with annexes Validation of the SOPs:  Validation of the SOPs The SOPs are subjected to evaluation by one or a number of the partners. The validation levels are given at the top of each SOP Validation by testing on selected inbred mouse strains and/or selected mutants at one EUMORPHIA laboratory Validation by testing on selected inbred mouse strains and/or selected mutants at two EUMORPHIA laboratories Full comparison of results of testing on selected inbred mouse strains and/or selected mutants at more than two EUMORPHIA laboratories 35% 44% 21% Slide13:  0 20 40 60 80 100 CNR GSF 0 20 40 60 80 100 0 20 40 60 80 100 MRC ICS 0 20 40 60 80 100 C57BL/6 C3HeH BALB/c 129/Sv Global % PPI 0 5 10 15 20 25 30 35 0 5 10 15 20 25 30 35 0 5 10 15 20 25 30 35 40 0 3 6 9 12 15 Open field % Centre Time 1st round validation results Audition and Balance:  Audition and Balance Close collaboration between workpackages: 8 Sensory systems 9 Central/peripheral nervous and skeletal muscle systems 10 Behaviour and cognition for cross lab validation, integration and ordering of the tests that cover hearing and balance. These include the modified SHIRPA, acoustic startle response, Pre-pulse Inhibition tests and the swim ability test.
