Reanalyzing microarray blood expression data from TB patients (n = 7) at enrollment (T0), and at T2 and T12 (elapsed time in months) after initiation of antimycobacterial treatment, we noticed a gradual trend of up-regulation of DOCK9 (p = 0.08) and EPHA4 mRNA (p = 0.0003), and down-regulation of NPC2 (p = 0.004), during follow up (Figure 5). This evidence concerns the gene DOCK9 and tuberculosis.
