Project description:We used B. melitensis M5-90 wild type to construct gene-deleted strains of B. melitensis ∆per, RAW264.7 cells infected with B. melitensis M5-90 and B. melitensis M5-90 ∆per for 4h, respectively. miRNA microarray and mRNA array experiments were performed, qRT-PCR validation for miRNAs and mRNAs. We performed a joint analysis of differentially expressed miRNAs and mRNAs, and proved that the target gene of miRNA-146b is Tbc1d14. It further confirmed that miR-146b targeting tbc1d14 regulates brucella-mediated autophagy of RAW264.7 cells. Finally, the molecular mechanism of tbc1d14 influencing brucella-mediated autophagy of RAW264.7 cells was preliminarily revealed by DGE sequencing.
