ABSTRACT
Aim To investigate the effect of 96 h paradoxical sleep deprivation(PSD) on learning & memory ability of rats and the concomitant gene expression change in the rat hippocampus.Methods PSD model was established by Modified Multiple Platform Method(MMPM).Learning and memory ability of the PSD model was assessed through hexagonal maze compared with the control, and the gene expression in hippocampus of each group was detected by gene chip technology.After that, GO and KEGG enrichment analysis were applied to determine the changes of the gene expression in PSD model compared with the control.Results PSD affected the memory consolidation process in rats.The gene chips showed that 100 genes expressed differently in the hippocampus of PSD model compared with the control, and among them, 25 genes were up-regulated and 75 genes down-regulated.The up-regulated genes mainly involved in cell growth and differentiation, learning and memory, inflammation, oxidative stress, and biological processes such as synaptic transmission, while the down-regulated genes mainly involved in immune response, central nervous system development, synaptic transmission, metabolism, signal transduction, neurotransmitter secretion, cell apoptosis, and so on.KEGG analysis showed that genes differentially expressed mainly involved in cGMP-PKG, metabolism, NF-kappa B and Pathways in cancer, and so on.Conclusion In rats, PSD leads to memory deficit, as well as a variety of gene expression changes in hippocampus of the PSD model.
