It is well established that nuclear factor kappa B (NF-κB) is a central regulator of the immune response and that dysregulation of NF-κB contributes to the pathogenesis of many autoimmune and inflammatory diseases. The food supplement Aquamin is a natural multi-mineral derived from the red algae Lithothamnion corallioides, rich in calcium, magnesium and 72 other trace minerals. This study descr...

We previously demonstrated that indoxyl sulfate induces senescence and dysfunction of proximal tubular cells by activating p53 expression. However, little is known about the role of nuclear factor (NF)-κB in these processes. The present study examines whether activation (phosphorylation) of NF-κB by indoxyl sulfate promotes senescence and dysfunction in human proximal tubular cells (HK-2 cells)...

The overexpression or mutation of epidermal growth factor receptor (EGFR) has been associated with a number of cancers, including head and neck squamous cell carcinoma (HNSCC). Increasing evidence indicates that both the phosphatidylinositol-3-kinase (PI3K)-Akt-mammalian target of Rapamycin (mTOR) and the nuclear factor-kappa B (NF-κB) are constitutively active and contribute to aggressive HNSC...

The discovery of functional crosstalk between WNT and nuclear factor κB (NF-κB) signaling has established a more complex role for these two pathways in inflammation and cancer. However, the molecular mechanisms of the crosstalk and its biological consequences are largely unknown. Here, we show that WNT/β-catenin signaling selectively inhibits the expression of a proinflammatory subset of IL-1β-...

Nuclear factor kappa B (NF-κB) is an inducible transcription factor that plays critical roles in immune and stress responses and is often implicated in pathologies, including chronic inflammation and cancer. Although much has been learned about NF-κB-activating pathways, the specific repression of NF-κB is far less well understood. Here we identified the type I protein arginine methyltransferas...

Osteoblasts produce various types of cytokines under pathological conditions and control osteoclast differentiation. Tumor necrosis factor-α (TNF-α) has been demonstrated to exert complex effects in osteoblasts under local inflammatory conditions, including in periodontal and periapical diseases. Interleukin-34 (IL-34) has been recently identified as a novel regulatory factor for the differenti...

The nuclear factor-kappa B (NF-κB) family of transcription factors has recently emerged as a major regulator of the growth and elaboration of neural processes. NF-κB signaling has been implicated in controlling axon initiation, elongation, guidance and branching and in regulating dendrite arbor size and complexity during development and dendritic spine density in the adult. NF-κB is activated b...

NF-κB (Nuclear Factor Κ-light-chain-enhancer of activated B cells) transcription factors are critical regulators of immunity, stress response, apoptosis, and differentiation. Molecular defects promoting the constitutive activation of canonical and non-canonical NF-κB signaling pathways contribute to many diseases, including cancer, diabetes, chronic inflammation, and autoimmunity. In the presen...

The transcription factor nuclear factor κB (NF-κB) regulates various cellular processes such as inflammation and apoptosis. The NF-κB essential modulator (NEMO/IKKγ) is indispensable for NF-κB activation by diverse stimuli including genotoxic stress. Here, we show that NEMO linear ubiquitination on K285/309 is critical for genotoxic NF-κB activation. The E3 ligase linear ubiquitin chain assembl...

NPM1/nucleophosmin is frequently overexpressed in various tumors, although the oncogenic role of NPM1 remains unclear. Here we revealed the link between NPM1 and nuclear factor-κB (NF-κB), a master regulator of inflammation. We found that NPM1 knockdown decreased NF-κB-mediated transcription of selected target genes by decreasing the recruitment of NF-κB p65 to the gene promoters. NPM1 is direc...
