Apoptosis or physiological programmed cell death is a molecular process observed during neurodegenerative diseases (Epilepsies, Alzheimer…). The neurodegeneration leads to the reorganization of synapses and neurons in the CNS. Consequently, searches for early medication are a major challenge in Neuroscience. To this aim, VALAPODYN, a European Commission funded research network, develops functional genomics and proteomics related to the dynamics of molecular interaction networks (MIN). MIN modeling investigates protein-protein interactions and regulation networks. Using a model of induced hippocampal sclerosis associated with focal epilepsy in the mouse, dynamic expression analyses are conducted at different time points. Hippocampal samples were subjected on 2D-DIGE analysis which allows quantification of cyanine labelled proteins. Biological variation analysis yields about 1500 protein spots. These spots include 34 protein spots to be differentially regulated. The distribution is consistent with the literature showing that CNS proteins are mainly composed of acidic and neutral proteins. Several proteins have multiple protein spots likely resulting from different isoforms. Spots of interest will be digested with proteases and analysed using MALDI/TOF-TOF. Total proteins mixture will also be submitted to ESI-MS after HPLC separation as a means of improving both protein and proteome coverage by using complementary instruments. [less ▲]

VALAPODYN is a research network funded by the European Commission (6th Framework Program) which is developing an original systems biology approach focused on the development of multidisciplinary functional genomics related to complex biological processes and cellular networks. The aim is to generate an innovative approach to model the dynamics of molecular interaction networks (MIN) in relation to cell death and survival to detect new therapeutic targets to treat human brain diseases. The project consists of fundamental genomics research which is integrating statistical data analysis with real biological data in order to functionally annotate genes and proteins. Specialized genomics and proteomics databases for MIN modeling are being used along with leading microarray and proteomics platform systems to investigate protein-protein interactions and regulation networks. This will help to identify and validate biological targets in complex intracellular pathways to cure multifactorial diseases. Dynamic modeling specifically addresses the systems biology of complex cellular pathways and transcriptional networks. The novel dynamic models will be validated by testing the selected drug targets on innovative in vivo and in vitro models of CNS pathologies. As opposed to most current biological data analysis methods, VALAPODYN develops a dynamic and quantitative analysis method for new therapeutic targets through MIN dynamic models. It will provide a cutting-edge highly accurate in silico tool for identifying novel and effective therapeutic targets in a much faster, more efficient and more economical way than it is possible today.
