Figure 3From: Oxidative stress induced Interleukin-32 mRNA expression in human bronchial epithelial cellsTranscription factors that bind to the IL-32 gene promoter. HBE cells were stimulated with H2O2, IFNγ, H2O2 + IFNγ, or vehicle for 30 minutes. The ChIP assay was performed to identify which transcription factors bind to the IL-32 gene promoter. Binding activity was compared using quantitative real-time PCR of the IL-32 promoter in DNA from chromatin complexes immunoprecipitated by antibodies to c-Jun (A), CREB (B), and RNA polymerase II (C). The bars show the means ± SE from 3 different individuals. *p < 0.01 significantly different.Back to article page
