Figure 3. The absence of a transcriptional response to isoniazid in NRP2 bacilli, verified by quantitative RT-PCR with a panel of genes chosen to exemplify the isoniazid transcriptional signature and the physiological status of bacilli.

Figure 3

Expression ratios, marked in fold-change, were calculated relative to sigA and drug-free growth controls using the ΔΔCt method. Standard deviations from triplicate samples are marked. Red–pink coloring highlights genes selected to assay INH mechanism of action; blue coloring indicates genes chosen to illustrate the metabolic and respiratory state of bacilli.

INH: Isoniazid; NRP: Nonreplicating persistence.
