ABSTRACT
Objective:To detect the changes of functional expression profile of energy metabolism related differential genes in sleep deprived rats before and after intervention by Tianwang Buxindan by microarray sequencing technology, so as to provide possible ideas and theoretical basis for the prevention and treatment of sleep deprivation. Method:The rats were randomLy divided into two groups: the Tianwang Buxindan group and the model group. The Tianwang Buxindan group was given the decoction of Tianwang Buxindan at the dose of 20 g·kg-1, and the model group was given the pure water of equal volume for 14 days. Taking liver, heart and hypothalamus as samples, high-throughput sequencing was used to obtain differential genes. Gene Ontology(Go)classification and kyoto Encyclopedia of Genes and Genomes (KEGG)pathway enrichment analysis were used to construct a co expression network with lncrna. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)was used to detect the mRNA expression levels of neuropeptide Y(NPY), bispecific phosphatase 1/mitogen-activated protein kinase phosphatase-1(DUSP1/MKP-1)and alpha-L-iduronidase(IDUA), three key genes with significant differences in energy metabolism. Result:The 321 differentially expressed genes were obtained, 231 of which were up-regulated and 90 down regulated, which mainly promoted the process of lipid metabolism, glucose metabolism and protein metabolism, participated in the synthesis and expression of fibrinogen, vitamin B6 and mesencephalic astrocyte-derived neurotrophic factor(MANF), and involved mitogen activated protein kinases(MAPK), p53 gene(p53), cyclic adenosine monophosphate(cAMP) and other signal pathways. Compared with the model group, the expression of IDUA significantly increased in the Tianwang Buxindan group (P<0.05), but decreased significantly in NPY and DUSP1(P<0.01). Conclusion:Tianwang Buxindan can interfere with the energy metabolism mechanism of sleep deprived rats in many ways. By down regulating the mRNA expression level of NPY and DUSP1 genes, it may activate the p38 MAPK signal pathway and affect the lipid metabolism.
