Differentially regulated genes induced in Mycobacterium smegmatis by in vitro acid-nitrosative multi-stress

ABSTRACT: Transcriptional profile of Mycobacterium smegmatis in in vitro acid-nitrosative multistress, comparing untreated control cells and bacteria under multi-stress. Two-condition experiment, MSMEG-K vs. MSMEG-ACID-NO treated. Biological replicates: 3 controls, 3 Acid-NO treated, independently grown and harvested. In controls and Acid-NO treated cells, good quality RNA samples obtained from each pellet were pooled together and used for microarray experiments to get an average of three separate experiments, three replicates per array.

ORGANISM(S): Mycobacterium smegmatis str. MC2 155

Several studies regarding the transcriptome of Mycobacterium tuberculosis following the exposure to various in vitro simulated phagosomal stressors, have already tried to elucidate the bacterium behavior during the intracellular infection. An in vitro acid-nitrosative multi-stress was carried out for M. tuberculosis H37Rv and Mycobacterium smegmatis MC(2)155 in order to analyze by DNA-microarray the gene expression changes associated respectively to pathogenic and non-pathogenic mycobacterial sp  ...[more]
