Abstract:ObjectiveTo identify differentially expressed genes in hippocampus of rats with high +Gz stress exposure and low +Gz preconditioning,so as to further understand the molecular mechanisms of positive acceleration induced brain injury. MethodsMale SD rats were randomly assigned to three groups: control group, +10 Gz stress group and low +Gz preconditioning group. Total RNA was prepared from experimental rats hippocampus after 24 hour of +10 Gz exposure. The method of microarray was applied to detect the differentially expressed genes and analyze the pathways through KEGG database.ResultsThe results showed that there were 846 genes differentially expressed in +10 Gz stress group and 992 genes in low +Gz preconditioning group compared with the control group. There were 56 KEGG pathways in +10 Gz stress group, 49 KEGG pathways in low +Gz preconditioning group.ConclusionsThe results indicated that the differentially expressed genes were involved in different signaling pathways. These patterns of gene expression might contribute to understanding the molecular mechanism of high +Gz stress-induced brain injury and its countermeasures.
