Project description:Echinoderms, possessing outstanding regenerative capability, provide unique model system for the study of the response to injury. However, there is little known about the proteomic composition of coelomic fluid, an important biofluid circulating through the whole body and reflecting an overall biological status of the organism. In this study, we used LC-MALDI tandem mass spectrometry to characterize proteome of cell-free coelomic fluid of starfish Asterias rubens and follow the changes occurring in response to puncture wound and blood loss. Our study demonstrated significant changes of CF proteome during the first hours after injury and presented a series of candidate proteins involved in early response to injury, providing interesting targets for future functional studies.
