Figure 6. Differential expression of apoptotic genes during infection of Rh-BMDMs with Mtb, relative to infection with the Mtb:Δ-sigH mutant.

Figure 6

The temporal expression changes of apoptotic genes as determined at the 24 hr time point by RT-PCR arrays specific for (Caspase dependent) apoptosis,to confirm microarray results at the 0 (A), 4 (B) and 24 (C) hrs. GAPDH was used as the invariant housekeeping control for normalization. The figure shows the arithmetic means ± standard deviations for two biological replicates. *, p<0.05; **, p<0.01, ***, p<0.001 and ****, p<0.0001.
