FIG. 3.
(A) Effects of protein tyrosine kinase inhibition on IL-8 gene transcription. The graph shows relative IL-8 mRNA expression corrected for total mRNA by using the housekeeping gene β-actin. mRNA bands were quantified by densitometry with NIH Image 1.58. (B) Nuclear binding of the transcription factor NF-κB in TB-infected human monocytes, as detected by electromobility gel shift analysis. All data are representative of the results of three independent experiments.
