Control of LPS induced gene expression in bone marrow derived macrophages by the p50/p105 subunit of NF-kB and IL-10

Project description:Bone marrow-derived macrophages were produced from mice lacking IL-10 alone (IL10-def) or mice lacking both IL-10 and the p50/p105 subunit of NF-kB (p50/IL10), and left unstimulated, stimulated with LPS (1 ng/ml) or stimulated with LPS and IL-10 (0.3 ng/ml). There are 12 total samples, with 2 each from the groups described in the summary. Pairwise comparisons between groups were evaluated.

An autoregulatory RelB:p50 NF-κB pathway perpetuates pro-survival TNF response in multiple myeloma

Project description:Pro-inflammatory cytokines were shown to promote growth and survival of cancerous cells. TNF induced RelA:p50 NF-κB dimer via the canonical pathway is thought to link inflammation with cancer. Integrating biochemical and computational studies we identify that deficiency of non-canonical signal transducer p100 triggers a positive autoregulatory loop, which instead perpetuates an alternate RelB:p50 containing NF-κB activity upon TNF treatment. TNF stimulated RelB:p50 dimer is sufficient for mediating NF-κB target gene-expressions and suppressing apoptotic cellular death independent of principal NF-κB subunit RelA. We further demonstrate that activating mutations in non-canonical NF-κB module deplete multiple myeloma cells of p100, thereby, provoking autoregulatory RelB:p50 activation. Finally, autoregulatory control reinforces protracted pro-survival NF-κB response, albeit comprising of RelB:p50, upon TNF priming that protects myeloma cells with dysfunctional p100 from subsequent apoptotic insults. In sum, we present evidence for positive autoregulation mediated through the NF-κB system and its potential involvement in human neoplasm.

Selective Regulation of a Defined Subset of Inflammatory and Immunoregulatory Genes by an NF-kB p50-IkBz Pathway

Project description:The five NF-kB family members and three nuclear IkB proteins play diverse biological roles, but the mechanisms by which distinct NF-kB and NF-kB:IkB complexes contribute to selective gene transcription remain poorly understood. Using nascent transcript RNA-seq, we observed considerable overlap between p50-dependent and IkBz-dependent genes in Toll-like receptor 4 (TLR4)-activated macrophages. Key inflammatory and immunoregulatory genes, including Il6, Il1b, Nos2, Lcn2, and Batf, were among the p50-IkBz co-dependent genes. IkBz typically bound genomic sites occupied earlier by NF-kB dimers. However, p50-IkBz co-dependence did not coincide with the preferential binding of either protein, as p50, IkBz, and RelA co-occupied thousands of sites. A common feature of p50-IkBz co-dependent genes was close proximity to a p50/RelA/IkBz co-bound site exhibiting p50-dependent binding of RelA and IkBz. This result and others suggest that IkBz function is not restricted to p50 homodimers. Notably, IkBz and the p50-IkBz target genes comprise a high percentage of genes that exhibited the greatest differential expression between TLR4-stimulated and tumor necrosis factor receptor (TNFR)-stimulated macrophages, with ectopic IkBz rescuing a subset of these genes. These results reveal a defined p50-IkBz pathway that selectively activates a set of key inflammatory and immunoregulatory genes and serves as an important contributor to the differential responses to TNFR and TLR4.
