Abstract

Objective— Inflammatory processes and foam cell formation are key determinants in the initiation and progression of atherosclerosis. Electrophilic nitro–fatty acids, byproducts of nitric oxide- and nitrite-dependent redox reactions of unsaturated fatty acids, exhibit antiinflammatory signaling actions in inflammatory and vascular cell model systems. The in vivo action of nitro–fatty acids in chronic inflammatory processes such as atherosclerosis remains to be elucidated. Methods and Results— Herein, we demonstrate that subcutaneously administered 9- and 10-nitro-octadecenoic acid (nitro-oleic acid) potently reduced atherosclerotic lesion formation in apolipoprotein E–deficient mice. Nitro–fatty acids did not modulate serum lipoprotein profiles. Immunostaining and gene expression analyses revealed that nitro-oleic acid attenuated lesion formation by suppressing tissue oxidant generation, inhibiting adhesion molecule expression, and decreasing vessel wall infiltration of inflammatory cells. In addition, nitro-oleic acid reduced foam cell formation by attenuating oxidized low-density lipoprotein–induced phosphorylation of signal transducer and activator of transcription-1, a transcription factor linked to foam cell formation in atherosclerotic plaques. Atherosclerotic lesions of nitro-oleic acid-treated animals also showed an increased content of collagen and α-smooth muscle actin, suggesting conferral of higher plaque stability. Conclusion— These results reveal the antiatherogenic actions of electrophilic nitro–fatty acids in a murine model of atherosclerosis.

  • In apolipoprotein E-deficient mice, subcutaneous injection of nitro-oleic acid markedly reduced atherosclerotic lesion formation, associated with antiinflammatory effects including reduction in foam cell formation through attenuation of oxidized LDL-induced phosphorylation of STAT-1.

    “Rudolph et al. demonstrated that subcutaneous injection of nitro-oleic acid markedly reduced atherosclerotic lesion formation in apoliproprotein E-deficient mice associated with a variety of antiinflammatory effects including reduction in foam cell formation through attenuation of oxidized LDL-induced phosphorylation of signal transducer and activator of transcription-1 (STAT-1) [139].”

  • Fatty acid nitroalkene administration reduces plaque formation in a rodent model of atherosclerosis.

    “Thus, in murine models of metabolic and inflammatory injury, fatty acid nitroalkene administration at nanomolar concentrations prevents restenosis after vessel injury (49), limits weight gain and loss of insulin sensitivity in murine models of metabolic syndrome (14), protects against ischemia-reperfusion injury (17,47,50), reduces plaque formation in a rodent model of atherosclerosis (51), and in”

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.
