Abstract

TNFalpha enhances the basal activity of the major Immediate Early (IE) enhancer/promoter of human cytomegalovirus (HCMV) in the immature premonocytic HL-60 cell line. The stimulatory effect of TNFalpha is mediated by induction of the transcription factor NF-kappaB, which specifically binds to the 18-bp repetitive sequence motif of the enhancer region. Complex formation could be competed by oligonucleotides representing the 18-bp sequence motif or the prototype NF-kappaB sequence of the immunoglobulin kappa gene. In gel mobility shift assays antisera specific to NF-kappaB p50 and p65 subunits were shown to react with the DNA-protein complex. Addition of the antioxidant PDTC blocked TNFalpha-mediated stimulation in a dose dependent manner. Electrophoretic mobility shift assays indicated that PDTC prevents NF-kappaB induction. Furthermore, it is suggested that protein kinases like PK-C are involved in the TNFalpha signal transduction pathway which leads to the activation of NF-kappaB and its binding to the HCMV IE enhancer in HL-60 cells. Our data are consistent with a role of TNFalpha in reactivation of latent HCMV infection in premonocytic cells.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • If antioxidant molecules are depleted in T cells, cytokine production can become uncontrolled, potentially resulting in an inflammatory environment that is known to reactivate CMV.

    “Finally, if antioxidant molecules are depleted in T cells, then cytokine production, can become uncontrolled (Michalek et al. 2012), potentially resulting in an inflammatory environment that is also known to reactivate CMV (Docke et al. 1994; Prosch et al. 1995; Stein et al. 1993).”

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.
