Genes operate as long as they are expressed and their expression is regulated at the transcriptional or post-transcriptional level purchase duphalac 100 ml without a prescription. Microarrays have additional applications in functional genomics apart from gene expression studies buy 100 ml duphalac, and other uses have also been reported safe 100 ml duphalac. A number of mutants carrying an insert in each gene were obtained, which were later isolated and identified (Sassetti 2001). In fact, gene knock-out followed by transcript analysis and proteome definition seems to be the way to identify essential genes. Subsequently, research derived from comparative genomic studies was directed towards the study of particular genes. Complementation and combination of in vitro and in vivo assay systems indicated the participation of the gene Rv1519 in the persistence and outbreak potential of this M. Thir- teen putative sigma (σ) factors and 192 regulatory proteins seem to be involved in the control of M. To date, consensus promoter sequences have been proposed for six σ factors, be- A sides the housekeeping σ factor, σ (for a review, see Rodriguez 2006). Gene ex- pression levels could be further modified by the action of transcriptional activators and repressors: regulatory proteins (Barnard 2004). These regulatory proteins in- clude 11 two-component systems, five unpaired response regulators, seven wbl genes, and more than 130 other putative transcriptional regulators (Cole 1998a). The differential expression of these regulatory gene products throughout different stages of the lifespan of M. In recent years, a number of reports have correlated the response of several of these transcriptional regulators to a variety of environmental stresses (for a summary, see Table 4-3 at http://www. However, the biological signals that stimulate the expression of the majority of them are still poorly recognized. Likewise, the connections between the different regulatory circuits of the complex network that controls gene expression in M. An example of the intricacy of this E network is the genetic regulation of sigB, which is induced by σ in response to H surface stress (Manganelli 2001) or by σ under heat shock and oxidative stress (Manganelli 2002). The regulation of sigB expression seems to be more complex F L than the above cited, given that σ - and σ -dependent promoters were identified in L the regulatory promoter region of sigB; and σ -dependent transcription was origi- H nated upstream to sigB (Dainese 2006). It has been shown that σ is also responsi- ble of the induction of sigE after heat shock and exposure to diamine (Raman 2001). Two-component signal transduction systems are composed of a histidine kinase sensor and a cytoplasmic response regulator that is activated by the cognate histidine kinase (West 2001). This regulon is responsible for the transcriptional changes during oxygen limitation, which is considered an important stimulus for the entry of M. Recently, the induction of sigB and sigE has been shown to depend on the two-component system MprA/MprB when the bacilli are subjected to surface stress (He 2006). The transcriptional regulator WhiB3 seems to positively regulate the expression of the housekeeping σ factor named sigA, by interacting with the subregion 4. Many of these anti-σ factors are located downstream of their cognate σ factor- encoding gene and both genes are usually co-transcribed (Bashyam 2004). Interestingly, RsbW, the σF-specific antagonist, is post-translationally regulated by two anti-anti- σ factors: RsfA and RskB (Beaucher 2002, Parida 2005). Although the function of many of these mycobacterial transcriptional regulators and signal transduction systems remains poorly defined, recent studies have begun to provide evidence of the biological role of these regulatory circuits throughout each stage of the lifecycle of M. The expression of sigA, sigE and sigG (Manganelli 2001, Capelli 2006, Volpe 2006), that of some 130 Genomics and Proteomics two-component systems (Ewann 2002, Haydel 2004, Walters 2006), as well as that of the transcriptional regulator whiB3 are induced during macrophage infection. The role of these transcriptional regulators in pathogenesis and virulence became even more evident in animal model experiments, where disruption or deletion of these genes was shown to affect M. These regulators can modify bacterial physiol- ogy and are able to modulate host-pathogen interactions in response to environ- mental signals. As mentioned previously, the tubercle bacillus adapts its transcriptome to the envi- ronment in which it replicates. The adaptation of a bacterium to harsh environ- ments involves the transcriptional activation of genes whose final products help the bacterium to reprogram its physiology, thus ensuring survival. Among the genetic determinants that the bacterium must modulate are those involved in intermediary and secondary metabolism, cell wall processes, stress responses and signal trans- duction pathways. Table 4-4 summarizes the most important genes whose expression is modulated by the transcriptional regulators mentioned previously (see section 4. On the contrary, the genes hspX (encoding the α-crystalline homologue), senX3 (sensor kinase), mtrA (response regulator), and fbpC (mycolyl transferase and fibronectine binding pro- tein or antigen 85C) were down-regulated in that mutant strain at different times of D the growth curve (Sun 2004). Genes induced by σ include the resuscitation pro- moting factor rfpC, several chaperone genes and genes involved in lipid metabo- lism and cell wall processes (Raman 2004). These include genes coding for some heat shock proteins 132 Genomics and Proteomics (hsp and clp), the trxB2C operon and some transcriptional regulators (Manganelli 2002). L At least four small operons appear to be directly regulated by σ : sigL-rslA, pks10- L pks7, mpt53-Rv2877c, and Rv1139c-Rv1138c, which clearly have a σ -consensus promoter sequence in their regulatory region (Hahn 2005, Dainese 2006). The pks genes are involved in the biosynthesis of phthiocerol dimycocerosate, a component of the cell envelope associated with virulence (Sirakova 2003); and the mpt operon contains genes involved in fatty acid transport (Sonden 2005). It was shown that the expression of this two-component system is highly induced under hypoxia (Sherman 2001b, Park 2003). A consensus dosR-specific binding motif was reported to be located up- stream of hypoxic response genes (Park 2003, Kendall 2004). The microarray ex- pression profiles of mutants in each of the components (dosR and dosS) showed that DosR is required for the expression of genes usually induced under oxygen limitation, such as hspX gene. However, it has not been clearly determined if the changes found in gene expression were directly or indi- rectly related to the lack of this two-component regulatory system (Parish 2003a). Recently, the global transcriptional profile of the two-component systems PhoP and MprA has been reported. One of these studies provided evidence that the PhoP/PhoR system is a positive transcriptional regulator of genes involved in the synthesis of the cell envelope of M. On the other hand, MprA regulates sigB and sigE and many other genes previously reported to be associated to various stress conditions (He 2006). In order to analyze the mechanisms involved in bacilli intracellular survival, myco- bacterial gene expression was determined in M. Macrophages have been investigated at different time points post-infection for the differential expression of various two-component system regulators (regX3, phoP, prrA, mprA kdpE, tcr, devR and tcrX) (Haydel 2004). In this work, the authors reported that ap- proximately one-third (32 %) of the genes upregulated by M. Interestingly, the authors observed high induc- tion of the sigma factor sigG and 13 other putative transcriptional regulators. Therefore, while significant work has been per- 134 Genomics and Proteomics formed on the gene expression profile of the host, information on M. So far, there is only one publication concerning global mycobacterial transcription expression in the animal model, using microarray as the analytical method (Talaat 2004). The same genes were also found to be induced 24 hours post-infection in murine bone marrow macrophages (Schnappinger 2003). Additionally, several genes were regulated up or down only in Balb/c mice, such as proZ (transport system permease protein), aceAa (probable isocitrate lyase involved in lipid metabolism), and genes encoding for regulatory proteins, such as sigK, sigE and kdpE.
