LPS stimulation of macrophages induces a large increase in TNF- mRNA by increasing gene transcription via activation of the transcriptional factors NF-B (13-15), c-jun, and c-fos (16). ... A study investigating the control of TNF- synthesis by using reporter constructs has demonstrated that this AU-rich element and the flanking sequences are sufficient to mediate a more than 200-fold increase in the LPS-dependent synthesis of the reporter protein. This element is involved in both the control of mRNA degradation and its translation This increase is not due to a change in cytoplasmic mRNA concentration but rather to a reversal of the translation repression in response to LPS ...The consequent increase in PDE activity leads to a decrease in cAMP, thus removing the cAMP constraint and allowing a full induction of TNF- mRNA and protein synthesis. The induction of PDE4B should then be viewed as a positive feedback loop that contributes to a full activation of the cytokine responses."; prov:wasQuotedFrom pubmed:12032334 . sub:_5 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:12032334; prov:wasDerivedFrom beldoc:, sub:_4 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:03.345+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
