Project description:Transcription profile of WT compare to sigma factor sigI deletion mutant at OD1 and OD2. This microarray is simple comparison of wild type strain of M. tuberculosis CDC1551 and its sigma factor gene deletion mutant (sigI) at OD1 and OD2, respectively.
Project description:To identify mediators of the osmotic stress response in Mycobacterium tuberculosis (Mtb), we performed transcriptional profiling of WT CDC1551 following treatment with 140 mM NaCl for 1 hr relative to an untreated control. 140 mM NaCl was chosen to reflect the approximate osmolarity of human plasma (i.e., 280 mOsm/L), which may be relevant during the course of infection.
Project description:To characterize the role of Rv0516c in the osmotic stress response of Mycobacterium tuberculosis (Mtb), we performed transcriptional profiling of CDC1551 Rv0516c::Tn following treatment with 140 mM NaCl for 1 hr relative to an untreated control.

CDC1551 was treated with 140 mM NaCl for 1 h and compared to the same strain treated with 0 mM NaCl for 0 h. 4 biological replicates, independently grown and harvested. One replicate per array.

Project description:Transcriptional profiling of Mycobacterium tuberculosis CDC1551 comparing control butyric acid-treated cells with 20mM db-cAMP treated cells after 2hrs of treatment with shaking at 200rpm at 37C.
Project description:Pulse chase SILAC was used to identify protein turnover within human macrophages infected with mycobacterium tuberculosis CDC1551, a ppe38-71 mutant strain, a complemented strain and an uninfected control.
Project description:Transcriptional profiling of Mycobacterium tuberculosis CDC1551 and 6-azasteroid resistant mutants ASR1 and ASR2 with treatment of 6-azasteroids, 4a and 6a, for 6 hours.
