Genome-wide maps of H3K4me1 in Mycobacterium tuberculosis H37Rv-infected macrophages

Project description:Host macrophage transcriptional responses to intracellular pathogens remain poorly characterized. We screened transcriptional enhancers engaged in response to M. tuberculosis (Mtb) infection by ChIPseq analysis of histone H3 lysine 4 monomethylation (H3K4me1). De novo monomethylation during infection was associated with genes implicated in host defense and apoptosis. These regions were enriched for binding sites for ETS transcription factor family members and response elements for nuclear receptors, including liver X receptors (LXRs) and peroxisomal proliferator activated receptors (PPARs), many of which were encompassed by transposable elements. LXRa expression was strongly induced by infection, whereas that of PPARs was unaffected. LXR DNA binding and NCoR corepressor recruitment increased proportionately in infected cells but coactivator association was unchanged, consistent with a lack of induction of endogenous agonists. However, treatment of infected cells with LXR agonist T0901317 strongly increased coactivator recruitment and induced a gene expression program characterized by enhanced innate immune signaling and lipid metabolism. Remarkably, T0901317 treatment selectively induced apoptosis in infected macrophages, and was accompanied by Mtb death, reducing mycobacterial burden 18-fold relative to vehicle 5d after infection. These studies define macrophage transcriptional responses to Mtb infection, and suggest that tissue-specific LXRa agonists may be efficacious in clinical management of tuberculosis.

Whole transcriptome profiling of H37Rv- and H37Rv△1759c-infected macrophages.

Project description:To explore the regulatory network of noncoding RNAs after M.tb infection and the role of Rv1759c in the infection process, we collected samples of H37Rv- and H37Rv△1759c-infected macrophages and explored the full transcriptome expression profile. We constructed DE-lncRNA/DE-circRNA-DE-miRNA-DE-mRNA regulatory networks during H37Rv and H37Rv△1759c infection. In addition, we first discovered the close relationship between Rv1759c and chemokines during M.tb infection by comparing the transcription profiles of H37Rv and H37Rv△1759c and bioinformatics analysis. Here, our study comprehensively characterizes the ncRNA and mRNA profiles in macrophages infected with H37Rv and H37Rv△1759c, which provides support and new directions for in-depth exploration of ncRNA and PE/PPE family functions during the infection process.

The association and difference of normal THP-1 cell and H37Rv infected THP-1 cell.

Project description:①Background:Tuberculosis is mainly a respiratory tract infection caused by mycobacterium tuberculosis and one of the leading causes of death worldwide. According to the Global Tuberculosis Report in 2021, About a quarter of the world's population is infected with Mycobacterium tuberculosis and China is the second highest burden of TB. Although TB diagnosis and prevention techniques have become more mature, the number of TB cases is still increasing, mainly due to: the prevalence of drug-resistant tuberculosis bacteria, tuberculosis and HIV co-infection, long incubation time of mycobacterium tuberculosis difficult to early diagnosis and so on. Therefore, it is of great significance to study the pathogenesis of mycobacterium tuberculosis infection.②Method: THP-1 cells were treated with 50ng/ml PMA for 24 hours, so that THP-1 cell can be induced into macrophages. After that THP-1 macrophages were infected with mycobacterium tuberculosis H37Rv(MOI=1), which were collected and applied to RNA-sequencing. The constructed sequencing library was sequenced using an Illumina Novaseq 6000 system.
