Abstract

Oxidative stress, i.e., excessive production of oxygen free radicals and reactive oxygen species, leads to lipid peroxidation and to formation of reactive aldehydes which act as second messengers of free radicals. It has previously been shown that oxidative stress may be involved in the transcriptional regulation of cytomegalovirus (CMV) immediate early promoter, involved in viral reactivation from latency. In the current study we used a plasmid containing the yellow fluorescent protein (YFP) gene under the control of CMV-1 promoter to monitor the influence of hydrogen peroxide and reactive aldehydes, 4-hydroxy-2-nonenal (HNE) and acrolein, on CMV-1 promoter activation in human embryonic kidney cells (HEK293). While acrolein was ineffective, hydrogen peroxide slightly (50 %) stimulated the CMV promoter. In contrast, HNE had a strong, up to 3-fold, enhancing effect on the CMV-1 promoter within four as well as after 24h of treatment. The most effective was the treatment with 24 microM HNE. This effect of HNE suggests that stressful conditions associated with lipid peroxidation could lead to CMV activation.

  • Reactive oxygen species and 4-hydroxy-2-nonenal (HNE) can directly reactivate CMV, but this process can be inhibited by antioxidants.

    “Mechanistic studies show that reactive oxygen species and one of the final products of lipid peroxidation, 4-hydroxy-2-nonenal (HNE), can directly reactivate CMV, but this process can be inhibited by antioxidants (Cinatl et al. 1999; Jaganjac et al. 2010; Speir 2000; Vossen et al. 1997).”

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.
