Project description:To investigate the effects of NFKB signaling, RNA-seq analysis was performed on both Jurkat and MT-2 cells. It was observed that either NFKB1 or NFKB2 knockout could alter the gene expression profile in MT-2 cells compared to Jurkat cells. Gene expression profiles of NFKB1/NFKB2 knockout Jurkat cells were compared to the mock edited Jurkat cells. On the other hand, it was hypothesized that the gene expression profile of MT-2 cells can be more drastically altered by NFKB1 or NFKB2 knockout. NFKB2 knockout MT-2 cells exhibited a unique gene expression profile compared to those of NFKB1 knockout MT-2 cells and mock edited MT-2 cells.

It was observed that either RELA or RELC knockout could alter the gene expression profile in MT-2 cells compared to Jurkat cells.Gene expression profiles of RELA-C knockout Jurkat cells were compared to the mock edited Jurkat cells. On the other hand, it was hypothesized that the gene expression profile of MT-2 cells can be more drastically altered by RELA or RELC knockout compared to RELB knockout.

Project description:NF-kappaB Activation Model includes the activation of both NFKB1:RELA and NFKB2:RELB for Canonical and Non-Canonical Pathway respectively.
The model includes the pathway model integrated with post-translational modifications of NF-kB subunits that regulate the NFKB1:RELA and NFKB2:RELB activity. The processes that are regulated by NF-kB pathway can be monitored through following readouts NFKB1:RELA Activity, NFKB2:RELB Activity, Degraded RelA, Degraded RelB, Degraded IkB, Degraded NIK, Apoptosis, Tumour, Antiviral Activity, B Cell Growth and Cell Migration. However, last 5 processes above are also influenced by other pathways too, therefore while making predictions, caution has to be exercised.

Project description:This study systematically analyzed the molecular mechanism and function of nuclear factor kappa B subunit 2 (NFKB2) in colorectal cancer (CRC) to investigate the potential of NFKB2 as a therapeutic target for CRCTo investigate the potential of NFKB2 as a therapeutic target for colorectal cancer (CRC), we conducted a systematic analysis of the molecular mechanism and function of NFKB2 in CRC. VariousA range of experimental techniques, including RNA sequencing, proteome chip assays, and small molecule analysis, were used to obtaingain a deeper understanding of the regulation of NFKB2 in CRC. TheOur results revealed that NFKB2 was upregulated in a significant proportion of patients with advanced hepatic metastasismetastases of CRC. NFKB2 played an importanta role in promoting tumor growth through CD8+ T cell exhaustion. MoreoverAdditionally, NFKB2 directly interacted with signal transducer and activator of transcription 2 (STAT2)STAT2, leading to increased phosphorylation of STAT2 and the upregulation of programmed death ligand 1 (PD-L1)PD-L1 expression. Applying aThe application of a small molecule inhibitor of NFKB2 (Rg5) led to a reduction in PD-L1 expression and improved response to programmed death-1 (PD-1)PD-1 blockade-based immunotherapy. In conclusion,These findings suggest that the facilitated NFKB2-STAT2/PD-L1 axis may suppresses immune surveillance in CRC and targeting NFKB2 maycould enhance the efficacy of immunotherapeutic strategies. Our resultsThis study provides novel insights into the molecular mechanisms underlying the contribution of NFKB2 in CRC immune escape. However, our findings requireand further validation of these findings in a clinical trial is needed to establish NFKB2 inhibition as a therapeutic strategy for CRC patients.

Project description:As such, TNF triggers the canonical NF-?B pathway to induce a nuclear NF-?B activity composed of the RelA:p50 dimer in WT cells. Nfkb2 encodes p100, which regulates the activity of the RelB NF-?B heterodimers during immune cell-differentiation via the noncanonical pathway. Our biochemical analyses revealed that an absence of p100 instead repositions RelB under the control of the TNF-activated canonical pathway. Indeed, chronic TNF treatment of Nfkb2-/- cells activates the RelA:p50 dimer and an additional RelB:p50 dimer. On the other hand, TNF stimulation of Relb-/-Nfkb2-/- and Rela-/-Nfkb2-/- MEFs exclusively activated the RelA:p50 dimer and the RelB:p50 dimer, respectively. We treated this panel of knockout MEFs with TNF for 6h before being subjected to microarray mRNA analysis. We also included in our analysis WT MEFs and Rela-/-Relb-/-Rel-/- MEFs, which served as a negative control. Our analyses revealed overlapping and distinct gene-expression specificities of RelA:p50 and RelB:p50 dimers activated in mutant cells in response to TNF.

Project description:The alternative (non-canonical) nuclear factor-kappa B (NF-κB) signalling pathway predominantly regulates the function of the p52/RelB heterodimer. Germline Nfkb2 deficiency in mice leads to loss of p100/p52 protein and offers protection against a variety of gastrointestinal conditions, such as azoxymethane/dextran sulfate sodium (DSS)-induced colitis-associated cancer and lipopolysaccharide (LPS)-induced small intestinal epithelial apoptosis. However, the common underlying protective mechanisms are not yet fully understood. Here we applied RNA sequencing and identified a B-lymphocyte defect as the major signature in the small intestinal mucosa of naïve adult Nfkb2-/- mice. Proteomics analysis also revealed a dramatic decrease in small intestinal immunoglobulin A levels, and this was validated by quantitative ELISA in both small intestinal lysates and serum. Moreover, the numbers of IgA-producing, CD138+ve plasma cells were also reduced in the lamina propria of the small intestinal villi of Nfkb2-/- mice. This phenotype was even more striking in the small intestinal mucosa of RelB-/- mice, although these mice were equally sensitive to LPS-induced intestinal apoptosis as their RelB+/+ wild-type counterparts. Therefore, p52 deficiency offers resistance to LPS-induced intestinal apoptosis and appears to regulate the plasma cell population within the gut.

Project description:We report the application of ChIP-Seq for high-throughput profiling of NFKB1/p50 binding dynamics. The binding profiles were performed under three conditions/models. We first examine the p50 binding in HEK293T cells during G1 and S phase. HEK293T cells were synchronized with double thymidine block method. Before and after release to S phase, ChIP was performed, and chromatin immunoprecipitated DNA was converted to libraries for sequencing with HiSeq 4000. We find that these NFKB1/p50 binding peaks in G1 phase dramatically reduced at S phase. Then, we further examine the p50 binding in HEK293T/TopBP1 cells in response to tamoxifen treatment. These cells have stable expression of TopBP1 activation domain fusion with estrogen receptor. After treatment, chromatin immunoprecipitated DNA was converted to libraries for sequencing with HiSeq 4000. We find that these NFKB1/p50 binding peaks in vehicle control sample dramatically reduced after tamoxifen treatment. Final, we compare the genome wide binding behavior of wild type p50 and mutant p50 2KR (K354R and K356R). HEK293T cells was transfected with plasmids expression HA-tagged wild type or mutation p50. Chromatin immunoprecipitated DNA was converted to libraries for sequencing with HiSeq 4000. We find that both wild type and p50 2KR mutant share similar binding profile. However, in general, p50 mutant has less binding affinity to NFKB binding sites. This study provides a preliminary but solid basis to our understanding of NFKB1/p50 binding dynamics.
