The activation of IL-1-induced enhancers depends on TAK1 kinase activity and NF-kappaB p65 II

ABSTRACT: The inflammatory gene response requires activation of the protein kinase TAK1, but it is currently unknown how TAK1-derived signals coordinate transcriptional programs in the genome. We determined the genome-wide binding of the TAK1-controlled NF-M-NM-:B subunit p65 in relation to active enhancers and promoters of transcribed genes by ChIP-seq experiments. Out of 35,000 active enhancer regions, 410 H3K4me1-positive enhancers show interleukin (IL)-1-induced H3K27ac and p65 binding. Inhibition of TAK1, IKK2 or depletion of p65 blocked inducible enhancer activation and gene expression. As exemplified by the CXC chemokine cluster located on chromosome 4, the TAK1-p65 pathway also regulates the recruitment kinetics of the histone acetyltransferase CBP, of NF-M-NM-:B p50 and of AP-1 transcription factors to both, promoters and enhancers. This study provides a high resolution view of epigenetic changes occurring during the IL-1 response and allows the first genome-wide identification of a novel class of inducible p65 NF-M-NM-:B-dependent enhancers in epithelial cells. Two sets of experiments were performed as biological replicate series (rep1 and rep2) each comprising 5 dual-color microarray hybridizations. The two series were performed with inverted Cy-Dye allocation (Dye-swap). Human epithelial KB cells were treated with Interleukin-1-alpha (10ng/M-BM-5l) for 0.5h, 1h, 3h or 24h, or, were left untreated. An individual set of samples was treated identically with IL1a but after an initial preincubation for 1h with PD98059 (50 micromol/l). Each dual-color microarray represents a direct comparison of samples preincubated or not with PD98059.

Cyclin-dependent kinase 6 is a chromatin-bound cofactor for nuclear factor kappaB-dependent gene expression [Agilent]

Project description:Given the intimate link between inflammation and dysregulated cell proliferation in cancer we investigated cytokine-triggered gene expression in different cell cycle stages. High density microarray analysis revealed that G1 release primes and cooperates with the cytokine-driven gene response. This effect is transmitted through CDK6 which shares the ability to regulate expression of inflammatory genes with its functional homologue CDK4. CDK6 contributes to the regulation of inflammatory gene expression by physical and functional cooperation with the NF-κB subunit p65 in the nucleus. ChIPSeq experiments showed a tight co-recruitment of CDK6 and p65 to enhancers and promoters of many transcriptionally active NF-κB target genes. While CDK6 recruitment to distinct chromatin regions of inflammatory target genes had no effect on histone modifications, it was essential for proper loading of NF-κB p65 to its cognate binding sites and for the function of p65 coactivators such as TRIP6. Furthermore, cytokine-inducible nuclear translocation and chromatin association of CDK6 depends on the kinase activity of TAK1 and p38. These results have widespread biological implications, as aberrant CDK6 expression or activation that is frequently observed in human tumors cooperates with NF-κB to shape the cytokine- and chemokine-repertoire in chronic inflammation and cancer. Four sets of experiments were performed in total (Exp1-4). Within each of these sets biological duplicates (Rep1-2) were included and analyzed. HeLa control cells or cells with established shRNA-mediated knockdown of CDK4 or CDK6 were analyzed. Cells were subjected to cell cycle arrest or were released from the arrested state for 6h. Cells were treated for 30 minutes with Interleukin-1-alpha at the arrested state or after release or were left untreated.
