Proteomics Analysis of the Cerebellum in Spontaneously Hypertensive Rats Treated with Twirling Reinforcing Manipulation, Twirling Reducing Manipulation or Electroacupuncture

Purpose: In this experiment, spontaneously hypertensive rats (SHR) were used to further explore the antihypertensive effect of acupuncture twirling reinforcing and reducing manipulation and the central effect mechanism of regulating blood pressure. Methods: 32 male SHR rats were randomly divided into 4 groups: twirling reinforcing manipulation group (RF), twirling reducing manipulation group (RD), electroacupuncture group (EA) (n = 8) and model group (M) (n = 8) and 8 WKY rats were used as blank control group (WKY). Group RD, RF and EA SHR took bilateral Taichong(LR3) point for acupuncture twirling method or electroacupuncture treatment, while WKY and M group did not use any acupuncture manipulation, but only carried out the same grasping and fixation. The differential proteins in cerebellum were screened by proteomic technology, and the key proteins and pathways involved in the pathogenesis of hypertension were selected.Results: RD, RF and EA lowered the blood pressures of the SHRs by varying degrees. The results of Parallel reaction monitoring(PRM) verification showed that among all the differential proteins, 13 differentially expressed proteins (DEPs) were selected for PRM verification. The KEGG annotations of differential proteins are involved in the regulation of lipolysis, autophagy, gap junction, phosphate inositol metabolism, splicing, lysosome, thermogenesis and RNA transport in adipocytes, etc. Conclusion: The results of the current study demonstrated that RD, RF and EA manipulations at the LR3 point reduced blood pressure and that RD was the most effective of the techniques used. Different acupuncture techniques have different pathways for screening and activating cerebellar differential proteins.
