1 Luiza Handschuh Karol Marcinkowski University of Medical Sciences, Department of Haematology Institute of Bioorganic Chemistry PAS, Center of Excellence for Nucleic Acid-based Technologies INGRID 2008, Lacco Ameno, VIRTUAL LABORATORY AND ITS APPLICATION IN GENOMICS

2 Virtual Laboratory - definition and advanteges „The Virtual Laboratory is a distributed workgroup environment, with the main task of providing a remote access to the various kind of rare and expensive scientific laboratory equipment and computational resources” (http://vlab.psnc.pl/)http://vlab.psnc.pl/  A specific representative of the RIS (Remote Instrumentation Systems)  Based on grid environment, already implemented in the VLab System by Poznan Supercomputing and Networking Center (PSNC)  Independent on physical location of the instruments  Designed to cooperate with many other grid systems  Devoted to experimental and computational tasks – supporting the postprocessing phase of experiment  Experiments made in other laboratories and their results can be shared enabling the workgroup

3 Modular architecture of the Virtual Laboratory system

4 Experiment execution in the Virtual Laboratory 1.Preparing a sample and/or input data (e.g. parameters) 1.Measurement/computation 2.Data processing and visualization 3.Data storage and management

5 Workflow management Dynamic Measurement Scenario (DMS) design:  Analysis of application  Connection diagram construction  Description of additional dependecies  Generation of applications and links description  Generation of the measurement scenario description an example workflow In Scenario Submission Application in NMR studies

6 Data storage and management Digital Library – a crucial component in most typical RIS & VL systems, a module responsible for data storage and management (DSM) -unique digital collection -possibility of software extention -cooperation with the library integrated systems, e.g. catalogue databases -possiblity of searching and browsing -widespread access (via Internet) Case diagram nodes – experimental/computational tasks; edges - paths of measurement execution follow

11 „Application of functional genomics tools for establishing complex model of tumor transformation. Studies on molecular mechanisms of acute myeloid leukemia pathogenesis” as a part of a huge project announced by Polish Ministry of Science and Informatization in 2005: „Application of functional genomics and bioinformatics for creation and characterisation of models describing biological processes of great importance in medicine and agriculture” ( PBZ-MNiI-2/1/2005) Institute of Bioorganic Chemistry PAS, Poznań Karol Marcinkowski University of Medical Sciences, Department of Haematology Poznań Supercomputing and Networking Center Poznań University of Technology

12 Research model – acute myeloid leukemia AML M1 FAB type AML M1 is almost homogenous cell population (myeloblasts consist 90% of the whole bone marrow cell pool) Molecular determinants of this AML type are still not well described.

14 Microarray construction Microarray of our own design – 924 oligonucleotide probes (DNA fragments, nt) complementary to the genes involved in AML pathogenesis and control ones AROS (70 nt)

15 Example of preprocessed microarray images The same slide No.19 HL6019sz

16 First step of computational work – data collection 1.Grid adjustment 2.Quantitative analysis - pixels counting for each spot and background (mean and median) Signal intensity: (65535)

21 High level analysis of microarray data - examples Left: 55 genes at least 4-fold overexpressed in the tested samples comparing to the healthy control Samples No. 20, 22 & 27 represent patients after treatment Wright: Genes differentiating samples with various types of leukemia

22 Experiment execution in the Virtual Laboratory of Genomics In future equipement should be directly available for scientists/doctors who work in other laboratories/institutes in Poland via Internet Now: only the multistep analysis of the microarray data can be automated: the same universal strategy will be applied in every case in order to obtain satisfactory gene expression results

23 Outlook of Virtual Laboratory of Genomics
