The genes fimA and omp2B are known to be upregulated by CpxRA, while lspB and dsrA are downregulated by activation of the CpxRA regulation system. These results, combined with the information in Figure 3C, led the authors to conclude that the CpxRA system was activated in the mtrC deletion mutant.

Human T cells were incubated with proteins produced from the cdt mutant-carrying plasmids (schematic in figure 3), and the cell cycle distribution was analyzed. Of particular interest are Figures 5bc, which demonstrate the high levels of G2 arrest in the cdtB mutant.

Cytotoxicity can be restored by mixture of CdtB and CdtC with the sonicated cell lysate of E. coli expressing cdtA. This recovery was not seen upon combination of CdtB and CdtC alone or with the sonicated cell lysate of E.coli carrying a control plasmid (Figure 4, especially 4G vs 4FH).
