Figure 8. No significant differences in transcriptional activity between the four promoter variants were detected.

FPR1 minimal promoters −88/41 −56C/−54G, −56T/−54G, −56C/−54C and −56T/−54C were cloned upstream from the luciferase reporter gene, electroporated into U937 cells and expression was analyzed in a dual luciferase assay, as previously described. The graphs show the mean ratios from seven experiments ± S.E.M. The differences are statistically not significant in one-way analysis of variance, p value = 0.391.
