Project description:Investigation of whole genome gene expression level changes in Mycobacterium tuberculosis treated with the DHFR inhibitor WR99210, compared to untreated cells. The antimycobacterial properties of WR99210 are further described in Gerum, A., Ulmer, J., Jacobus, D., Jensen, N., Sherman, D., and C. Sibley. 2002. Novel Saccharomyces cerevisiae screen identifies WR99210 analogues that inhibit Mycobacterium tuberculosis dihydrofolate reductase. Antimicrob Agents Chemother 46(11):3362-3369 [PMID:12384337]
Project description:Mycobacterium tuberculosis (MTB) is a species of pathogenic bacteria and the causative agent of tuberculosis. The type strain H37Rv has been sequenced in 1998, while many previous studies found its predicted genes exhibit frequent errors, particularly in start codons. Here, we applied a TMPP [(N-Succinimidyloxycarbonylmethyl) tris (2,4,6-trimethoxyphenyl) phosphonium bromide] labeling combined with StageTip separating strategy to characterize the N-terminal peptides. We identified 2,598 annotated proteins, which 1,078 proteins were labeled by TMPP.
Project description:Transcriptional profiling of H37Rv (WT), Mut1 and Comp1 bacteria under aerobic (Aer/0 day, i.e 0 D) and hypoxic conditions (Hyp/5 days standing culture, i.e 5 D). Mut1: H37Rv carrying devR gene disruption by in frame insertion of kanamycin resistance cassette and expressing DevRN-Kan fusion protein. Comp1: Mut1 complemented with low copy number plasmid carrying devR gene expressed from its native constitutive upstream promoter. (Reference: Majumdar et al., 2010, PLoS One 5:e9448). Goal is to compare transcriptional patterns of WT, Mut1 and Comp1 strains under aerobic (0 D) and hypoxic (5 D) conditions in vitro.

The antimycobacterial properties of WR99210 are further described in Gerum, A., Ulmer, J., Jacobus, D., Jensen, N., Sherman, D., and C. Sibley. 2002. Novel Saccharomyces cerevisiae screen identifies WR99210 analogues that inhibit Mycobacterium tuberculosis dihydrofolate reductase. Antimicrob Agents Chemother 46(11):3362-3369 [PMID:12384337] A nine chip experiment in which total RNA was collected from H37Rv after treatment with 100 uM WR99210 for 0, 4, and 24 hours. Three separate cultures/biological replicates were interrogated for both treated and untreated cultures. Labeled cDNA was hybridized to NimbleGen spotted oligo tiling arrays covering both strands of the M. tuberculosis genome at ~200 bp intervals between 60-mer probes.
