ABSTRACT

Objective To analyze differences in gene expression profile of pituitary tissue in cervical spondylosis of vertebral artery type(CSA)model rats and explore the mechanism of adrenal gland's regulation of CSA.Methods Ten SPF male Wistar rats were randomly divided into model group and blank group.The CSA model was established by compound modeling method.The total RNA was extracted from the pituitary;the gene expression profile was detected by whole gene chip,ontology(GO),and signal pathway analysis.Results Compared with the normal group,the differential genes'expression profile analysis showed that the total number of the differential genes was 321(fold change︱ ＞ 2,P＜0.05),with 203 up-regulated genes and 118 down-regulated genes.A total of 1 294 genes rich in GO function were involved in the regulation of intercellular signal activity and nerve cell function;the stress response to external stimuli;and the regulation of coagulation function,angiogenesis, endometrial system,and cell cycle;There were 145 signal transducers,including adipocytokine signaling pathway, TGF-β signal transduction,AMPK signaling pathway,PPAR signal pathway,Wnt signaling pathway,and MAPK signal transduction pathway.Conclusion The pituitary regulates CSA mainly through the inflammatory stimulation,immune regulation,regulation of vertebral artery function,and endometrial system.
