This review is a meta-analysis of data describing proteins regulated by morphine influence studied worldwide across last years administration. Up to date (July 2010), 15 studies concerning this subject have been published. Animal models, examined brain structures, the route of morphine administration and proteomic platforms used for identification of differentially expressed proteins were described. Standardization of obtained results allowed for creation of database of proteins, whose expression was altered by morphine administration ( Their analysis by tools available in Celera Panther Database was possible too. Proteins, which seem to be the most promising candidates for further research, due to their consistent appearance in different studies, were indicated. Created database may facilitate further studies by providing a possibility to compare results obtained during different experiments. At the end, dynamic picture of proteome after morphine administration, which emerges from the obtained results, is discussed and need for standardization of proteomics experiments is stressed. As meta-analysis is a very powerful tool for evaluation and comparison of multiple data. We believe this approach will be useful in the nearest future to extract vital information from a vast number of similar publications. Morphinome database created already by our group is a comfortable tool for validation and verification of new data received after morphine influence on proteomes investigations. It gives a chance for fast comparison of results without hours spent on life science literature mining.
