RT-qPCR of selected genes confirms microarray expression trends. A, shows the microarray data of the genes used to confirm microarray expression trends. Fold difference (-CAM) is the fold change of differentially expressed THP-1 genes in response to C. burnetii infection after mock treatment. Fold difference (+CAM) is the fold change of differentially expressed THP-1 genes in response to C. burnetii infection after CAM treatment. B, difference in mRNA levels in selected genes relative to β-actin. An equal amount of total RNA from each sample was analyzed by RT-qPCR. The Y-axis represents fold changes in gene expression while X axis shows the conditions under which gene expression was observed (mock and CAM treated, and uninfected and C. burnetii infected THP-1 cells). U-CAM, uninfected THP-1 minus CAM. U+CAM, uninfected THP-1 plus CAM. I-CAM, infected THP-1 minus CAM. I+CAM, infected THP-1 plus CAM. The results represent the mean of three biological samples and three technical replicates of each sample. Error bars represent the s.e.m.
