ERbeta influencing p65 cistromes in colon cancer cells

Project description:Inflammation is involved in both initiation and promotion of colorectal cancer (CRC), and patients with inflammatory bowel disease (IBC) have increased risk of developing CRC. Tumor necrosis factor alpha (TNFα) is a cytokine secreted by e.g. macrophages, and this signaling is deregulated in IBD and CRC. TNFα activates the pro-survival transcription factor complex NFκB, which is composed of several subunits including p65 (RELA). We recently characterized the genome-wide transcriptional impact by TNFα in two CRC cell lines, but how p65 binds the chromatin, its cistrome, in colorectal cancer cells has not been explored. We here used p65 chromatin immunoprecipitation followed by sequencing (ChIP-Seq) in HT29 and SW480 cells, and correlated with the transcriptomic impact of TNFα. Further, estrogen receptor beta (ERβ) has anti-inflammatory and anti-tumorigenic effects in colon cells and interacts with NFκB main targets. We have shown that ERβ impacts TNFα signaling in CRC cells and ERβ impacts the P65 cistrome.

Myeloid cell RelA/p65 promotes lung cancer proliferation

Project description:Smoking is the most important risk factor for both lung cancer (LC) and chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate the role of myeloid cell NF-kB in the regulation of tumor cell growth signaling. We subjected mice lacking myeloid RelA/p65 to a metastatic LC model. Cigarette smoke (CS) exposure significantly increased the proliferation of Lewis lung carcinoma cell (LLC) tumors in wild type mice. In CS exposed mice lacking myeloid RelA/p65, the tumor growth was largely inhibited. Transcriptome and pathway analysis of cancer tissue revealed a fundamental impact of myeloid cells on various growth signaling pathways. Myeloid RelA/p65 is necessary to link smoke-induced inflammation with LC growth. Keywords: Expression profiling by array Analysis of gene expression in lewis lung carcinoma cells resected from lungs of WT and RelA/p65 deficient mice exposed to smoke or air. Four different samples were analyzed (3 replicates each).

p65-HaloTag copurifying proteins in human 293T cells

Project description:In effort to develop methodology for targeted top down mass spectrometry of NF kappa B p65 from human cells, we evaluated the utility of HaloTag for purification and analysis of recombinant protein. During our study, two datasets of bottom up LC-MS/MS were generated: one from in-gel digestion of the predominant band following p65-HaloTag purification, another from in-solution digestion of all the proteins present in a p65-HaloTag purification. p65-HaloTag copurifying proteins identified in our datasets include the known interactors c-Rel, NF-kappaB p105, NF-kappaB p100, and NF-kappaB inhibitor beta. Over 100 proteins were identified by at least two peptides using a Mascot ion cut-off score of 30.
