Abstract: 【Objective】 This study was aimed to investigate the damage effect of Brucella virulence factor A (BvfA) in Sertoli cells (TM4 cells),so as to reveal the pathogenic mechanism of Brucella on host.【Method】 RNA-Seq double-end sequencing,Label-free proteomics and LC-MS non-target metabolomics were used to analyze the omics difference of TM4 cells infected with Brucella S19△bvfA and S19 strains.The differentially expressed proteins and differential metabolite pathways were analyzed using KEGG database,and the protein expression were validated by parallel reaction monitoring (PRM).【Result】 There were 400 differentially expressed genes,422 differentially expressed proteins and 271 differential metabolites in TM4 cells infected with S19△bvfA and S19 strains.Multi-omics analysis showed that the common KEGG pathway of differentially expressed genes,proteins and metabolites in TM4 cells infected with S19△bvfA and S19 strains was retrograde endocannabinoid signaling pathway.In this pathway,20 proteins expression was down-regulated in mitochondrial NADH-ubiquinone redoxase Complex Ⅰ of TM4 cells infected with S19△bvfA strain.PRM result showed that the expression trends of Ndufb11,Ndufa9,Ndufv1,Ndufv2,Ndufs8 and Ndufs2 in Complex Ⅰ were consistent with the results of Label-free proteomics.【Conclusion】 BvfA induced variations of transcriptional,protein and metabolic levels in Brucella infected TM4 cells,and BvfA down-regulated the expression of NADH-ubiquinone oxidoreductase complex proteins in mitochondria of Sertoli cells.
