NF-κB Regulates Phagocytic NADPH Oxidase by Inducing the Expression of gp91

Abstract

The superoxide-generating phagocytic NADPH oxidase is an important component of the innate immune response against microbial agents, and is involved in shaping the cellular response to a variety of physiological and pathological signals. One of the downstream targets of NADPH oxidase-derived radicals is the ubiquitous transcription factor NF-kappaB, which controls the expression of a large array of genes involved in immune function and cell survival. Here we show that NF-kappaB itself is a key factor in controlling NADPH oxidase expression and function. In monocytic and microglial cell lines, the expression of the NADPH oxidase subunit gp91(phox) was induced by lipopolysaccharide/interferon gamma treatment and was inhibited in cells constitutively expressing IkappaBalpha. Furthermore, inducible reactive oxygen species production was inhibited in IkappaBalpha overexpressing cells. gp91(phox) expression was very low in RelA(-/-) fibroblasts and could be induced by reconstituting these cells with p65/RelA. Thus, gp91(phox) expression is dependent on the presence of p65/RelA. We also found that gp91(phox) transcription is dependent on NF-kappaB and we identified two potential cis-acting elements in the murine gp91(phox) promoter that control NF-kappaB-dependent regulation. The findings raise the possibility of a positive feedback loop in which NF-kappaB activation by oxidative stress leads to further radical production via NADPH oxidase.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
