摘要	Morphological alterations of synapse are found after morphine administration, suggesting that regulation of synaptic plasticity may be one of the mechanisms of neuroadaptation in addiction. However, the molecular basis underlying the abnormal synapse morphological and physiological changes in the morphine-induced dependence, withdraw, and relapse is not well understood. As prefrontal cortex ( PFC) is one of the most important brain regions, which provides executive control over drug use and is severely impaired in many addicts, systematic analysis of the biochemical and molecular alteration of synaptic fraction of PFC in morphine-induced neuroadaptation is necessary. In this study, differential protein expression profiling of synaptic fraction of rat PFC based on morphine-induced conditioned place preference ( CPP) model was performed with two-dimensional gel electrophoresis ( 2-DE). Our results showed that a total of 80 proteins were differentially expressed by 2-DE analysis during three phases of CPP assay. Of them, 58 were further identified by mass spectrometry. These proteins were classified into multiple categories, such as energy metabolism, signal transduction, synaptic transmission, cytoskeletal proteins, chaperones, and local synaptic protein synthetic machinery according to their biological functions. Our study provides a global view of synaptic-related molecular networking in PFC under morphine-induced dependence, withdraw, and relapse, indicative of a concerted biological process in neuroadaptation under chronic morphine exposure.; Morphological alterations of synapse are found after morphine administration, suggesting that regulation of synaptic plasticity may be one of the mechanisms of neuroadaptation in addiction.
