FIG. 4.
Differential expression of genes involved in iron transport and acquisition. The heat map quantifies the changes elicited by CORM-3 and iCORM3 in selected genes; it should be noted that the “heat scale” at the right is expressed as the natural logarithm of the fold changes in individual genes of the heme-deficient mutant of E. coli (hemA) and the corresponding wild-type grown anaerobically in defined medium after addition of 100 μM CORM-3 or, for the mutant only, 100 μM iCORM-3.
