Systematic review on the proteomic profile of Mycobacterium tuberculosis exposed to drugs.

The authors present an overview about proteomics studies in Mycobacterium tuberculosis exposed to some anti-tuberculosis drugs and new candidates, using two-dimensional gel electrophoresis and mass spectrometry. To date, that the authors have knowledge, this is the first studies that was performed specifically in M. tuberculosis using systematic review on electronic literature conducted in three databases using the following search terms: tuberculosis OR mycobacterium tuberculosis, proteome OR proteomics, and mass spectrometry electrospray ionization OR matrix-assisted laser desorption ionization OR two-dimensional gel electrophoresis. By electronic search, 622 abstracts of the original articles published from November 2003 to March 2016 were selected. After the selection, four articles fulfill proposed criteria and were included in this study. The studies reported changes in the protein profile of M. tuberculosis after exposure to isoniazid, ethambutol, streptomycin, ofloxacin, moxifloxacin and two new drugs candidates, SQ109 and ATB107. In conclusion, the proteins changes were related to the synthesis of mycolic acids, cellular metabolism pathways, bacterial stress and starvation.
