Project description:The main objective of this study is to analyze changes in whole-genome transcriptomic profile of ERDMAN_2020(-) strain of Mycobacterium tuberculosis Erdman after ATc-dependent conditional depletion of ERDMAN_2020 by RNA Seq. Total 798 transcripts were found differentially regulated in three biological replicates with log2 fold change ≥ 1 and p-value ≤ 0.05 from. ERDMAN_2020 belongs to MerR family of transcription regulators. Treatment of ERDMAN_2020(-) strain with 50ng/ml ATc for 4 days resulted in accumulation of 338 transcripts and suppression of 460 transcripts, compared to the empty vector control.
Project description:We report the effects of VapC21 overexpression on Mycobacterium tuberculosis H37Rv strain. The total RNA was isolated from M. tuberculosis harboring either pTetR-int or pTetR-Int-vapC21 the expression was induced with 50 ng/ml anhydrotetracycline for 24 hrs. We report the effect of deletion VapC21 on the transciptional profile of Mycobacterium tuberculosis Erdman strain. For RNA-seq analysis, total RNA was isolated from mid-log phase culture of either parental or △vapC21 mutant strain.
Project description:To identify cellular pathways altered in autophagy-deficient macrophages during M. tuberculosis infection, we performed 3' Tag-RNA-seq on RNA harvested from Atg5fl/fl LysMcre+/+, Atg16L1fl/fl LysMcre+/+ and Atg7fl/fl LysMcre+/+ mouse bone marrow derived macrophages, and their respective LysMwt/wt control cells, both after 48 hours of infection with M. tuberculosis Erdman and or in mock-infection controls.
Project description:The new microarray described for Mycobacterium tuberculosis in our study has a more complete reprensentation of the genome than any other array design reported till date. Further, protocols for sample preparation, labelling and hybridisation for accurate gene expression profiling of M.tuberculosis have been optimised.
