Fig. 6. Modulation of host cell genes involved in the regulation of the NF-B pathway by T. gondii. Densitometric values were normalized to actin, and levels of gene expression are shown as infected/uninfected ratios (see color key showing relative fold change). Data represent the means of three experiments performed separately. The complete data sets with means ± s.d. are shown in Table S1 (supplementary material). Target genes of NF-B are shown in bold. Pos. indicates position in the array.
