Project description:The peritoneal macrophages were infected with Mtb H37Rv for 4 hours, and the miRNA expression profile were analyzed with deep sequencing.
Project description:The goal of this study is to perform transcriptome profiling of both infected and uninfected WT and HIF-1ɑ-/- peritoneal macrophages using RNA sequencing techniques. For that, WT and HIF-1ɑ-/- peritoneal macrophages were infeced for 6 hours with L. donovani promastigotes (or left uninfected as a control) and RNA samples were stored in TRI reagent (Sigma), for further analysis.
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.
Project description:The C57B/6 mice were infected with Mtb H37Rv (CFU=200) for 28 days, and the miRNA expression profile from lung tissues were analyzed with deep sequencing.
Project description:Purpose: The goals of this study are to investigate the differentially expressed miRNAs between ALV-J-infected primary monocyte-derived macrophages (MDM) and uninfected control by Illumina deep sequencing. Methods:Total RNA from two ALV-J-infected MDM (designated: J3h_1, J3h_2, J36h_1 and J36h_2) and two uninfected MDM samples (designated: NC3h_1, NC3h_2, NC36h_1 and NC36h_2) was isolated by TRIzol following the manufacturer’s instruction at 3 h post infection (hpi) and 36 hpi. RNA samples of two individuals within each group were pooled with equal amounts, and then were subjected to Illumina deep sequencing by Illumina Hiseq 2000. Results: compared to the uninfected MDM, we identified 13 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 3 hpi, and 6 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 36 hpi. Conclusions: Our results suggest that DE miRNAs involved in the immune response induced by ALV-J infection in MDM at 3 hpi. In addition, only 25 miRNAs-target DEGs were identified in MDM with ALV-J infection at 36 hpi, and these target DEGs can’t be significantly enriched in any GO terms and KEGG pathway..
