Host transcriptomic analysis of THP-1 infected with Mtb and MtbΔwhiB3
Ontology highlight
ABSTRACT: To study the role of WhiB3 in regulating host transcriptome, THP-1 were activated with PMA and infected with Mtb and MtbΔwhiB3, host transcriptome was studied.
Project description:Infection is a dialog between the pathogen and the host. Understanding the molecular basis of infection requires understanding the responses and adaptations of both the pathogen and host as a consequence of this dialog. We studied Mtb infection in human THP-1 cells by transcriptomics profiling of host expression over the course of an acute to anestablished infection.

Project description:We examined the microRNA profiles of THP-1 macrophages upon the MTB infection of (1) Beijing/W and non-Beijing/W clinical strains, and (2) susceptible and multidrug-resistant (MDR-) MTB strains. THP-1 cells were induced differentiation into a macrophage phenotype. Then cells were infected with three MDR (INHR, RIFR) Beijing/W, three sensitive (INHS, RIFS) Beijing/W, three MDR(INHR, RIFR) non-Beijing/W, and three sensitive (INHS, RIFS) non-Beijing/W strains. Total RNA were extracted and transfered into cDNA for miRNA profile analysis. Non-infected cells were used as control.

Project description:Transcriptional response of THP-1 cells infected with Mycobacterium tuberculosis utilizing ‘Active’ Mtb and ‘Dormant’ Mtb infection models at different time points. Analysis of the transcriptomic data deciphered the perturbation of gamut of host cellular pathways that are common and differentially manifested in the ‘Active’ Mtb and ‘Dormant’ Mtb infection models.
Project description:Global gene expressions of Mtb-infected mouse lungs were compared between with and without PDE4 inhibitor treatment. A lot of host genes are differentially expressed 21d and 28d post-Mtb infection. PDE4 inhibitor, however, downregulate 10% of genes among those and genes differentially regulated by PDE4 inhibitor are mainly involved immune response. Total RNA was isolated from Mtb-infected mouse lungs with or without CC-3052 (25 mg/kg/day) using Trizol reagent and gene profile was analyed using Affymetrix mouse ST 1.0

Project description:The analysis of differentially regulated mRNAs candidates in THP-1 cells infected with H37Rv was conducted, comparing them to both uninfected THP-1 cells and transfected reference samples. THP-1 cells are monocytes that differentiate into macrophages after being treated with PMA for 48 hours. Total RNA was isolated from the infected and transfected THP-1 cells at 24 hours post-infection.
Project description:To compare gene expression changes induced by infection with Mycobacterium tuberculosis (Mtb) with changes induced by purified Mtb products, we infected THP-1 cells with Mtb strain H37Rv or treated with purified Mtb products, then performed RNAseq.
Project description:Differentially regulated miRNA candidates in H37Rv infected THP-1 cells were analysed with respect to uninfected THP-1 reference samples. THP-1 cells are monocytes differentiated to macrophages after treatment with PMA for 48 hrs. Total RNA was isolated from infected THP-1 cells after 24 hrs of infection, cDNA was synthesized for TLDA real time PCR reaction using TaqMan MicroRNA Reverse Transcription kit and Megaplex Human Pool A and Pool B stem loop RT primers (version 3.0) as per manufacturer’s protocol. Further real time reaction was performed on QuantStudio 12K Flex Real-Time PCR System (Applied Biosystems) by using cDNA (without pre-amplification) on TLDA card A and card B (version 3.0).
