Impact of the vitamin B12 on the transcriptional regulation of the Mycobacterium tuberculosis Complex. Impact of the vitamin B12 on the transcriptional regulation of the Mycobacterium tuberculosis Complex

The transcriptome in response to vitamin B12 was interrogated in three M. tuberculosis Complex species: M. tuberculosis H37Rv, M. tuberculosis GC1237, and M. bovis AF2122/97. Examination of the core B12 transcriptome resulted in a robust differential regulation of 7 genes in the three species analysed Overall design: Each Mycobacterium tuberculosis heterotypic synonym (M. tuberculosis H37Rv, M. tuberculosis GC1237, and M. bovis AF2122/97) was grown in standard laboratory media supplemented with or without vitamin B12. Two replicates of each strain were processed in each condition (2 with B12 and 2 without B12 for each strain). RNA was extracted and subjected to RNA-seq. Expression profiles for each DNA strand (plus and minus) were obtained for the three species analysed.
