Project description:Mycobacterium leprae, the causative agent of leprosy, an obligate intracellular pathogen has the ability to survive and grow for extended periods within phagocytes and Schwann cells. M. leprae genome analysis predicts a highly degraded genome resulting in a significant loss of its genomic coding capacity. Detailed dynamics of carbon sources for energy utilization and growth of M. leprae is unclear. This study, therefore, presents M. leprae transcriptome during in vivo growth and ex vivo stationary phases, and explores metabolic pathways relevant to its growth from global gene expression data. This report provides a glimpse of some of M. leprae nutritional requirements for growth, which most likely, needs to be supplemented, in an axenic growth media.
Project description:Our object is to characterize the distinguish gene enrichment group in skin of Mycobacterium leprae (M. leprae)-infected footpads compared to that of Mycobacterium leprae (M. leprae) non-infected footpads.
Project description:Identification of the specific SigA binding regions on the B. subtilis chromosome during exponential, transition and stationary growth phases. The data served to help the analysis of the repertoire of B. subtilis promoters established from transcriptome profiles.

Project description:Identification of the specific SigA binding regions on the B. subtilis chromosome during exponential, transition and stationary growth phases. The data served to help the analysis of the repertoire of B. subtilis promoters established from transcriptome profiles. 3 growth phases (exponential, transition, stationary) x 2 biological replicates were analysed on the BsubT2 tiling array.

Project description:Our object is to characterize the distinguish gene enrichment group in skin of Mycobacterium leprae (M. leprae)-infected footpads compared to that of Mycobacterium leprae (M. leprae) non-infected footpads. One-condition experiment, Skin of M. leprae non-infected footpads (control) vs. Skin of M. leprae infected footpads (sample). Biological replicates: 3 control and 3 sample, independently grown and harvested from isolator. One replicate per array.
Project description:We have determined the time-resolved transcriptome of the model gram-positive organism B. subtilis during growth on rich medium. DNA microarrays were used to monitor gene transcription in 10-minute intervals at 40 consecutive timepoints. From the growth curve and a PCA analysis of all gene expression levels, we identified 4 distinct growth phases: a lag phase, an exponential growth phase, and very clearly separated early and late stationary growth phases
