TNF-α Modulation of Intestinal Epithelial Tight Junction Barrier Is Regulated by ERK1/2 Activation of Elk-1
Open accessAbstract
Tumor necrosis factor (TNF-α) is a proinflammatory cytokine that plays a critical role in the pathogenesis of inflammatory bowel disease. TNF-α causes an increase in intestinal permeability; however, the signaling pathways and the molecular mechanisms involved remain unclear. The major purpose of this study was to investigate the role of MAP kinase pathways (ERK1/2 and p38 kinase) and the molecular processes involved. An in vitro intestinal epithelial model system consisting of Caco-2 monolayers and an in vivo mouse model system were used to delineate the cellular and molecular mechanisms involved in TNF-α effects on tight junction barrier. The TNF-α-induced increase in Caco-2 tight junction permeability was mediated by activation of the ERK1/2 signaling pathway, but not the p38 kinase pathway. Activation of the ERK1/2 pathway led to phosphorylation and activation of the ETS domain-containing transcription factor Elk-1. The activated Elk-1 translocated to the nucleus, where it bound to its binding motif on the myosin light chain kinase (MLCK) promoter region, leading to the activation of MLCK promoter activity and gene transcription. In addition, in vivo intestinal perfusion studies also indicated that the TNF-α-induced increase in mouse intestinal permeability requires ERK1/2-dependent activation of Elk-1. These studies provide novel insight into the cellular and molecular processes that regulate the TNF-α-induced increase in intestinal epithelial tight junction permeability.

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.
