2 IMGM Laboratories your outsourcing partner IMGM Laboratories 2009 Slide 3 IMGM your outsourcing partner some basic facts IMGM Laboratories was founded d in 2001 We are located on the biotech campus Martinsried / Munich We operate as service provider offering advanced genomic services Our customers come from academia, pharma and biotech a flexible and reliable partnership (e.g. small and dedicated team) IMGM Laboratories 2009 Slide 4

3 IMGM your outsourcing partner some basic facts strategic partnership with the Center for human genetics and laboratory medicine Dr. Klein & Dr. Rost full accreditation according to DIN EN ISO/IEC full accreditation for expression analysis based on whole genome microarrays and quantitative real-time PCR Agilent Certified Service Provider IMGM Laboratories 2009 Slide 5 IMGM Laboratories Service Portfolio IMGM Laboratories 2009 Slide 6

4 Service Portfolio IMGM Laboratories 2009 Slide 7 Service Portfolio RNA services RNA services: Microarrays (Agilent platform, multiple options) Real-Time PCR (AB 7900HT, TaqMan arrays, 96- and 384-well blocks, gene expression studies) microrna profiling RNA isolation RNA quality control (Agilent Bioanalyzer Nanodrop) IMGM Laboratories 2009 Slide 8

5 micrornas and their potential in diagnostics IMGM Laboratories 2009 Slide 9 mirnas in diagnostics mirnas / mirna profiles: association to ~70 diseases (HMDD, human microrna disease database, last update ) active players in human oncogenesis e.g. mir-21 onco-mirna for breast cancer (Qian et al. (2008) Breast Cancer Res Treat; c.f. Sassen et al. (2008) Virchows Arch 452: classify human cancers e.g. Lu et al. (2005) Nature 435: Volinia et al. (2006) Proc Natl Acad Sci USA 103: IMGM Laboratories 2009 Slide 10

6 mirnas in diagnostics mirnas / mirna profiles associated with: disease prognosis: mir-221/222 cluster associated with poor prognostic in thyroid papillary carcinomas, pancreatic adenocarcinoma & glioblastoma (Lesage et al. (2007) Cell Cycle 6) Low let-7(a) expression associated with shorter survival and poor prognosis for lung cancer patients t (Takamizawa et al. (2004)Cancer Res 64: ; Yanaihara et al. (2006) Cancer Cell 9: ) prognosis of therapy outcome and response high expression of mir-21 associated with poor survival and poor therapeutic outcome of colon adenocarcinoma (Schetter et al. (2008) JAMA 299(4): ) prediction of chemotherapeutic response in patients with breast cancer according to mirna signature (Salter et al. 2008) PLoSOne 3(4):e1908) IMGM Laboratories 2009 Slide 11 mirnas in diagnostics Actual examples of mirna diagnostic tests: Chronic pancreatitis vs. pancreatic cancer (Asuragen) Prediction of colon cancer (launch early 2009, Exiqon A/S) Differentiation of mesothelioma from other cancers (mirview meso, Rosetta Genomics) Identification of squamous-type lung cancers (mirview squam, Rosetta Genomics) Identification of tissue-of-origin of metastatic tumors (mirview mets, Rosetta Genomics) IMGM Laboratories 2009 Slide 12
