TL;DR: The transcription factor NF-κB has attracted widespread attention among researchers in many fields based on its unusual and rapid regulation, the wide range of genes that it controls, its central role in immunological processes, the complexity of its subunits, and its apparent involvement in several diseases.
Abstract: ▪ Abstract The transcription factor NF-κB has attracted widespread attention among researchers in many fields based on the following: its unusual and rapid regulation, the wide range of genes that it controls, its central role in immunological processes, the complexity of its subunits, and its apparent involvement in several diseases. A primary level of control for NF-κB is through interactions with an inhibitor protein called IκB. Recent evidence confirms the existence of multiple forms of IκB that appear to regulate NF-κB by distinct mechanisms. NF-κB can be activated by exposure of cells to LPS or inflammatory cytokines such as TNF or IL-1, viral infection or expression of certain viral gene products, UV irradiation, B or T cell activation, and by other physiological and nonphysiological stimuli. Activation of NF-κB to move into the nucleus is controlled by the targeted phosphorylation and subsequent degradation of IκB. Exciting new research has elaborated several important and unexpected findings that...

TL;DR: Recently, significant advances have been made in elucidating the details of the pathways through which signals are transmitted to the NF-kappa B:I kappa B complex in the cytosol and their implications for the study of NF-Kappa B.
Abstract: ▪ Abstract The transcription factor NF-κB, more than a decade after its discovery, remains an exciting and active area of study. The involvement of NF-κB in the expression of numerous cytokines and adhesion molecules has supported its role as an evolutionarily conserved coordinating element in the organism's response to situations of infection, stress, and injury. Recently, significant advances have been made in elucidating the details of the pathways through which signals are transmitted to the NF-κB:IκB complex in the cytosol. The field now awaits the discovery and characterization of the kinase responsible for the inducible phosphorylation of IκB proteins. Another exciting development has been the demonstration that in certain situations NF-κB acts as an anti-apoptotic protein; therefore, elucidation of the mechanism by which NF-κB protects against cell death is an important goal. Finally, the generation of knockouts of members of the NF-κB/IκB family has allowed the study of the roles of these protein...

TL;DR: The specificity of various NF-κB proteins, their role in inflammatory disease, the regulation of NF-β proteins and IκB activity by IκBs and IkkB kinase, and the development of therapeutic strategies aimed at inhibition are discussed.
Abstract: Activation of the NF-κB/Rel transcription family, by nuclear translocation of cytoplasmic complexes, plays a central role in inflammation through its ability to induce transcription of proinflammatory genes (1). This pathway is activated upon appropriate cellular stimulation, most often by signals related to pathogens or stress. Here we will discuss the specificity of various NF-κB proteins, their role in inflammatory disease, the regulation of NF-κB activity by IκB proteins and IκB kinase (IKK), and the development of therapeutic strategies aimed at inhibition of NF-κB.

TL;DR: It is shown that although deletion of IKKbeta in intestinal epithelial cells does not decrease inflammation, it leads to a dramatic decrease in tumor incidence without affecting tumor size, which is linked to increased epithelial apoptosis during tumor promotion.

TL;DR: This work has elucidated how LPS is recognized by monocytes and macrophages of the innate immune system and activates a variety of transcription factors that include NF-kappaB (p50/p65) and AP-1 (c-Fos/c-Jun), which coordinate the induction of many genes encoding inflammatory mediators.
