Circulating levels of linoleic acid and HDL-cholesterol are major determinants of 4-hydroxynonenal protein adducts in patients with heart failure. Redox Biol 2013; 2:148-55.

Abstract
OBJECTIVE Measurements of oxidative stress biomarkers in patients with heart failure (HF) have yielded controversial results. This study aimed at testing the hypothesis that circulating levels of the lipid peroxidation product 4-hydroxynonenal bound to thiol proteins (4HNE-P) are strongly associated with those of its potential precursors, namely n-6 polyunsaturated fatty acids (PUFA). METHODS AND RESULTS Circulating levels of 4HNE-P were evaluated by gas chromatography-mass spectrometry in 71 control subjects and 61 ambulatory symptomatic HF patients along with various other clinically- and biochemically-relevant parameters, including other oxidative stress markers, and total levels of fatty acids from all classes, which reflect both free and bound to cholesterol, phospholipids and triglycerides. All HF patients had severe systolic functional impairment despite receiving optimal evidence-based therapies. Compared to controls, HF patients displayed markedly lower circulating levels of HDL- and LDL-cholesterol, which are major PUFA carriers, as well as of PUFA of the n-6 series, specifically linoleic acid (LA; P=0.001). Circulating 4HNE-P in HF patients was similar to controls, albeit multiple regression analysis revealed that LA was the only factor that was significantly associated with circulating 4HNE-P in the entire population (R (2)=0.086; P=0.02). In HF patients only, 4HNE-P was even more strongly associated with LA (P=0.003) and HDL-cholesterol (p<0.0002). Our results demonstrate that 4HNE-P levels, expressed relative to HDL-cholesterol, increase as HDL-cholesterol plasma levels decrease in the HF group only. CONCLUSION Results from this study emphasize the importance of considering changes in lipids and lipoproteins in the interpretation of measurements of lipid peroxidation products. Further studies appear warranted to explore the possibility that HDL-cholesterol particles may be a carrier of 4HNE adducts.

Abstract
In this review, we provide a comprehensive bibliographic overview of the role of mass spectrometry and the recent technical developments in the detection of post-translational modifications (PTMs). We briefly describe the principles of mass spectrometry for detecting PTMs and the protein and peptide enrichment strategies for PTM analysis, including phosphorylation, acetylation and oxidation. This review presents a bibliographic overview of the scientific achievements and the recent technical development in the detection of PTMs is provided. In order to ascertain the state of the art in mass spectrometry and proteomics methodologies for the study of PTMs, we analyzed all the PTM data introduced in the Universal Protein Resource (UniProt) and the literature published in the last three years. The evolution of curated data in UniProt for proteins annotated as being post-translationally modified is also analyzed. Additionally, we have undertaken a careful analysis of the research articles published in the years 2010 to 2012 reporting the detection of PTMs in biological samples by mass spectrometry.

Lipid peroxidation end product 4-hydroxy-trans-2-nonenal triggers unfolded protein response and heme oxygenase-1 expression in PC12 cells: Roles of ROS and MAPK pathways. Toxicology 2013; 315:24-37. [PMID: 24291486 DOI: 10.1016/j.tox.2013.11.007] [Citation(s) in RCA: 242] [Impact Index Per Article: 22.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2013] [Revised: 11/16/2013] [Accepted: 11/20/2013] [Indexed: 11/23/2022]
Abstract
This study investigates the roles of ROS overproduction and MAPK signaling pathways in the induction of unfolded protein response (UPR) and the expression of Phase II enzymes in response to 4-hydroxy-trans-2-nonenal (4-HNE) in a neuronal-like catecholaminergic PC12 cells. Our results showed that 4-HNE triggered three canonical pathways of UPR, namely IRE1-XBP1, PERK-eIF2α-ATF4 and ATF6, and induced the expression of UPR-targeted genes, GRP78, CHOP, TRB3, PUMA, and GADD34, as well as Phase II enzymes, HO-1 and GCLC. 4-HNE also induced apoptosis, intracellular calcium accumulation, caspase-3 activation, and G0/G1 cell cycle arrest, which was correlated with the increased expression of GADD45α. The addition of tiron, a cellular permeable superoxide scavenger, scavenged 4-HNE-mediated ROS formation, but did not alleviate cytotoxicity, or the expression of UPR-targeted genes or Phase II enzymes, indicating that ROS overproduction per se did not play a major role in 4-HNE-caused deleterious effects. HO-1 expression was attenuated by Nrf2 siRNA and chemical chaperone 4-phenylbutyrate (4-PBA), suggesting HO-1 expression was regulated by Nrf2-ARE, which may work downstream of ER stress. 4-HNE treatment promptly induced ERK, JNK and p38 MAPK activation. Addition of p38 MAPK specific inhibitor SB203580 attenuated HO-1 upregulation, but enhanced expression of CHOP, PUMA and TRB3, and cytotoxicity. These results indicate that 4-HNE-induced transient p38 MAPK activation may serve as an upstream negative regulator of ER stress and confer adaptive cytoprotection against 4-HNE-mediated cell injury.
