RNA-seq based transcriptinal profiling of intracellular Brucella abortus and Brucella abortus-infected murine macrophages

Project description:We describe the isolation of sufficient Brucella abortus RNA from primary host cell environment using modified reported methods for RNA-seq analysis, and simultaneously characterize the transcriptional profiles of intracellular B. abortus and bone marrow-derived macrophages (BMM) from BALB/c mice at 24 h (replicative phase) post-infection.

Gene expression profiling of Brucella abortus-infected mouse macrophages

Project description:Gene expression analysis of wild-type and STING knock-out mouse bone marrow-derived macrophages (mBMDM) infected with Brucella abortus or transfected with Brucella abortus DNA. Genes whose expression are affected by Brucella abortus in a STING-dependent manner will be identified and signaling pathways regulated by STING will be elucidated.

Genome analysis of gene expression by THP-1 macrophage during Brucella abortus wild type and mutant strains infection

Project description:Brucella abortus (B. abortus), an intracellular bacterium, is the causative agent of Brucellosis. This organism invades into macrophages and then survives through its abilities to modulate host cells functions. The biggest problem caused by B. abortus is that it prevents macrophage elimination and makes it difficult to remove B. abortus from the host body. Therefore, it is essential to identify the bacterial genes involved in virulence factor as a first step to understanding the bacterial pathogenicity and controlling Brucellosis. To identify these genes, B. abortus mutant strains were generated using transposon mutagenesis and transcriptomic profile during macrophage infection were analyzed. The gene expression level was analyzed using total RNA obtained from THP-1 cells infected with B. abortus wild type and mutant strains and cellular immunity during the infections were compared to wild type infected cell to identify the role of genes in B. abortus pathogenicity. Transcriptomic profiling showed that two mutant strains having disrupted genes related to 4-hydrobenzoate 3-monooxygenase (PHBH) of C1 strain and heme exporter protein cytochrome C (CcmC) of C10 strain, induced suppression of cytokine expression during infection in human macrophages. Conversely, two other mutant strains of exopolyphosphatase (PPX)of C27 and Peptidase M24 of C32 induced activation of cytokine expression in the THP-1 macrophage cells.

RNase and sRNA activity in Brucella abortus

Project description:Isogenic deletion and truncation of specific genes encoding RNases in Brucella abortus were analyzed for changes in gene expression. The main goal of this work is to determine the mRNAs that exhibit dysregulation when small regulatory RNAs (i.e., Bsr8) or RNases (i.e., RNaseE and RNaseJ) are invactivated in Brucella abortus. Small regulatory RNAs often control gene expression by binding directly to mRNAs to block translation or induce their degradation, and RNA from a deletion of one sRNA gene, bsr8, was analyzed to uncover the mRNAs that may be controlled by BsrB. RNases are enzymes that cleave RNAs during processing, turnover, and regulatory events, and RNaseE and RNaseJ appear to be important for B. abortus virulence. Therefore, to determine the mRNAs potentially targetd by these RNases, RNA from a strain harboring a RNaseE truncation and a strain carrying a deletion of rnaseJ were analyzed. In the end, the objective of this study was to gain insight into the regulatory patterns of specific B. abortus sRNAs and RNases.
