Résumé
Objective To investigate the expression of gene Fmr1 in rats cortex, hippocampus and hypothalamus areas after the rapid eyes movement ( REM ) sleep deprivation .Methods Using the modified multiple platform method (MMPM), 126 rats were randomly and averagely divided into three groups , the normal control group ( CC), the environmental control group (TC) and the sleep deprivation group (SD).Each group was detected on day 1, day 2, day 3, day 5, day 7, and day 9, and the sample tissues were extracted from 7 rats at each time point.Immunohistochemistry and RT-PCR were operated to analysis the expression of gene Fmr 1.Results The expressions of gene Fmr1 were increased gradually in the cortex and thalamus of the SD group after 3 days ( P 0.05).The expressions of gene Fmr1 were decreased gradually in hippocampus for SD after 3 days ( P 0.05 ) . Conclusion The expressions of gene Fmr 1 were increased gradually in the cortex and thalamus but decreased in the hippocampus in the SD group after 3 days.
