Gene expression profling of Mycobacterium tuberculosis H37Rv and H37RvΔdosSΔdosT in 0.2% glucose/acetate under aerobic/hypoxic conditions. Gene expression profling of Mycobacterium tuberculosis H37Rv and H37RvΔdosSΔdosT in 0.2% glucose/acetate under aerobic/hypoxic conditions

The present study reports the gene expression data of Mycobacterium tuberculosis H37Rv and H37RvΔdosSΔdosT (DKO) grown on 0.2 % acetate/glucose under aerobic/hypoxic conditions. Acetate was reported to be present in granulomas of Mycobacterium tuberculosis infected guinea pigs which are also hypoxic. By exposing Mycobacterium tuberculosis H37Rv and H37RvΔdosSΔdosT to different combinations of granulomatous stresses (acetate/glucose and aerobic/hypoxic conditions) alongwith other experimental data, we were able to delineate a new signaling pathway that activates DevR (DosR) regulon through Acetyl phosphate. The presence of two pathways highlights the importance of targeting DevR and not DevS/DosT for intercepting DevRST signalling cascade.
