FIG. 3.

Northern blot analysis of P. aeruginosa PA103 induced genes. Each panel depicts the quantified expression level relative to GAPDH expression (top), Northern blot autoradiograms of the specific gene (center), and the GAPDH loading control (bottom). Cells were infected with each indicated strain for 3 and 4 h. ADM and TRXIP are examples of class A and B genes, respectively. DUSP1, NR4A1, Fos, RhoB, and IL-6 are examples of class C genes, and SCYA2 and TIEG are examples of class D genes. GenBank accession numbers of clones from which the Northern probes were constructed are also noted.
