Abstract

Manganese superoxide dismutase (MnSOD), a tumor necrosis factor (TNF)-inducible reactive oxygen-scavenging enzyme, protects cells from TNF-mediated apoptosis. To understand how MnSOD is regulated, transient transfections of promoter-reporter gene constructions, in vitro DNA binding assays, and in vivo genomic footprint (IVGF) analysis were carried out on the murine MnSOD gene. The results of this analysis identified a 238-bp region of intron 2 that was responsive to TNF and interleukin-1beta (IL-1). This TNF response element (TNFRE) had the properties of a traditional enhancer element that functioned in an orientation- and position-independent manner. IVGF of the TNFRE revealed TNF- and IL-1-induced factor occupancy of sites that could bind NF-kappaB and C/EBP. The 5' portion of the TNFRE bound C/EBP-beta in vitro and was both necessary and sufficient for TNF responsiveness with the MnSOD promoter or with a heterologous promoter when in an upstream position. The 3' end of the TNFRE bound both NF-kappaB and C/EBP but was not necessary for TNF responsiveness with the MnSOD promoter. However, this 3' portion of the TNFRE was required for the TNFRE to function as a downstream enhancer with a heterologous promoter. These data functionally separate the MnSOD TNFRE into a region responsible for TNF activation and one that mediates induction when it is downstream of a promoter.

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.
