Nitro-fatty acids as novel electrophilic ligands for peroxisome proliferator-activated receptors

Ferreira, Ana M., Minarrieta, Lucía, Lamas Bervejillo, María, Rubbo, Homero·2012·Free Radical Biology and Medicine

Abstract

Lipid nitration has been observed during oxidative/nitrative stress conditions generating a variety of biomolecules capable of modulating cellular responses. This concept has grown as a result of studies with nitro-derivatives of long-chain unsaturated fatty acids containing a nitroalkene group (nitro-fatty acids). This review focuses on the interactions of nitro-fatty acids with members of the peroxisome proliferator-activated receptors (PPARs) family. These nuclear receptors belong to a superfamily of ligand-activated transcription factors, which serve as sensors of lipophilic molecules and regulate the expression of a set of genes involved in glucose and lipid metabolism. Here we discuss how nitro-fatty acids bind and activate PPARs, including the current knowledge of the molecular interactions and cell signaling events involved as well as their therapeutic potential associated with chronic inflammation and metabolic disorders.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Previously reported targets of nitroalkylation include Cys285 of PPARγ, Cys273 and Cys288 of Keap1, heat shock proteins, and Cys38 of the p65 subunit of NF-κB.

    “Previously reported targets of nitroalkylation include the Cys285 of PPARγ (peroxisome proliferator activator receptor γ) [35], Cys273 and Cys288 of the Nrf2 regulatory protein Keap1 [Kelch-like ECH-associated protein 1 (Keap1)/regulator of nuclear factor (erythroid-derived-2)-like 2 (Nrf2)] [12], heat shock proteins[12], and Cys38 of the p65 subunit of nuclear factor κB (NF-κB) [36] (Fig. 5).”

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.
