We conclude that heat shock increases I-κBα mRNA expression in BEAS-2B cells by activating the I-κBα promoter, and propose that heat shock-mediated up-regulation of I-κBα is a potential mechanism by which the heat shock response inhibits proinflammatory responses in lung cells. Heat shock-mediated induction of I-κBα was associated with inhibition of NF-κB activation. Transient transfection assays with a plasmid containing the reporter gene firefly luciferase, under the control of the human I-κBα promoter, demonstrated that heat shock activated the I-κBα promoter. Coincubation with actinomycin-D inhibited heat shock-mediated expression of I-κBα mRNA. NF-B acts as a central mediator of immune and inflammatory responses, and is involved in stress responses and regulation of.Abstract THE NF-B TRANSCRIPTION. Analysis of the promoter region in the NFKBIE (IB) gene showed similarly moderate counts of the IRF and NF-B TFBS, with strong overlapping IRF1/IRF2/IRF3 sites in human, chimpanzee and cattle. Induction of the heat shock response in BEAS-2B cells, a human cell line representative of bronchial epithelium, increased expression of I-κBα mRNA in a time-dependent manner. THP1 dual cells (Invivogen) featuring the secreted luciferase reporter gene, under the control of an ISG54 minimal promoter in conjunction with five. NFKBIA gene promoter contains a high number of NF-B family binding sites, which are not adjacent to the sparsely distributed IRF binding sites. Under basal conditions NF-κB is retained in the cytoplasm by an inhibitory protein called I-κB which exists as two major isoforms: I-κBα and I-κBβ. Among its related pathways are MyD88 dependent cascade initiated on endosome and Activation of NF-KappaB by PKR. It is composed of three key elements: an ELAM proximal promoter, five NF-kB repeated transcription factor binding. Diseases associated with NFKBIA include Ectodermal Dysplasia And Immunodeficiency 2 and Hypohidrotic Ectodermal Dysplasia With Immunodeficiency. pNiFty2-SEAP plasmid is Zeocin resistant. Recently, a functional insertiondeletion polymorphism in the promoter of NFKB1 (94ins/delATTG in relation to the transcription initiation site or 24. Recent data indicate that the heat shock response inhibits nuclear translocation of the proinflammatory transcription factor NF-κB. NFKBIA (NFKB Inhibitor Alpha) is a Protein Coding gene.
