Abstract
Ferroptosis and apoptosis are two types of regulated cell death that are closely associated with the pathophysiological processes of many diseases. The significance of ferroptosis-apoptosis crosstalk in cell fate determination has been reported, but the underlying molecular mechanisms are poorly understood. Herein mitochondria-mediated molecular crosstalk is explored. Based on a comprehensive spectroscopic investigation and mass spectrometry, cytochrome c-involved Fenton-like reactions and lipid peroxidation are revealed. More importantly, cytochrome c is found to induce ROS-independent and cardiolipin-specific lipid peroxidation depending on its redox state. In situ Raman spectroscopy unveiled that erastin can interrupt membrane permeability, specifically through cardiolipin, facilitating cytochrome c release from the mitochondria. Details of the erastin-cardiolipin interaction are determined using molecular dynamics simulations. This study provides novel insights into how molecular crosstalk occurs around mitochondrial membranes to trigger ferroptosis and apoptosis, with significant implications for the rational design of mitochondria-targeted cell death reducers in cancer therapy.

Chlorinated Phospholipids and Fatty Acids: (Patho)physiological Relevance, Potential Toxicity, and Analysis of Lipid Chlorohydrins. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:8386362. [PMID: 28090245 PMCID: PMC5206476 DOI: 10.1155/2016/8386362] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Revised: 10/24/2016] [Accepted: 11/06/2016] [Indexed: 12/17/2022]
Abstract
Chlorinated phospholipids are formed by the reaction of hypochlorous acid (HOCl), generated by the enzyme myeloperoxidase under inflammatory conditions, and the unsaturated fatty acyl residues or the head group. In the first case the generated chlorohydrins are both proinflammatory and cytotoxic, thus having a significant impact on the structures of biomembranes. The latter case leads to chloramines, the properties of which are by far less well understood. Since HOCl is also widely used as a disinfecting and antibacterial agent in medicinal, industrial, and domestic applications, it may represent an additional source of danger in the case of abuse or mishandling. This review discusses the reaction behavior of in vivo generated HOCl and biomolecules like DNA, proteins, and carbohydrates but will focus on phospholipids. Not only the beneficial and pathological (toxic) effects of chlorinated lipids but also the importance of these chlorinated species is discussed. Some selected cleavage products of (chlorinated) phospholipids and plasmalogens such as lysophospholipids, (chlorinated) free fatty acids and α-chloro fatty aldehydes, which are all well known to massively contribute to inflammatory diseases associated with oxidative stress, will be also discussed. Finally, common analytical methods to study these compounds will be reviewed with focus on mass spectrometric techniques.

Abstract
AIM We sought serum biomarkers predictive of pre-eclampsia (PE). MATERIALS & METHODS Sera obtained at 12-14 weeks of pregnancy from 24 cases who later developed PE and 24 controls with uncomplicated pregnancies were processed and analyzed using a serum proteomic approach. RESULTS Many statistically significant serum PE biomarker candidates (n > 60) were found comparing cases and controls. In addition, logistic regression analysis modeled biomarker data resulted in 14 different multimarker combinations having high detection sensitivity and specificity (AUC >0.9). CONCLUSIONS Developed panels of serum biomarkers appeared effective in identifying pregnant women at 12-14 weeks gestation at risk of PE later in their pregnancy.

Abstract
Extracellular traps (ETs) are reticulate structures of extracellular DNA associated with antimicrobial molecules. Their formation by phagocytes (mainly by neutrophils: NETs) has been identified as an essential element of vertebrate innate immune defense. However, as ETs are also toxic to host cells and potent triggers of autoimmunity, their role between pathogen defense and human pathogenesis is ambiguous, and they contribute to a variety of acute and chronic inflammatory diseases. Since the discovery of ET formation (ETosis) a decade ago, evidence has accumulated that most reaction cascades leading to ET release involve ROS. An important new facet was added when it became apparent that ETosis might be directly linked to, or be a variant of, the autophagy cell death pathway. The present review analyzes the evidence to date on the interplay between ROS, autophagy and ETosis, and highlights and discusses several further aspects of the ROS-ET relationship that are incompletely understood. These aspects include the role of NADPH oxidase-derived ROS, the molecular requirements of NADPH oxidase-dependent ETosis, the roles of NADPH oxidase subtypes, extracellular ROS and of ROS from sources other than NADPH oxidase, and the present evidence for ROS-independent ETosis. We conclude that ROS interact with ETosis in a multidimensional manner, with influence on whether ETosis shows beneficial or detrimental effects.

Abstract
Oxidized (phospho)lipids are of paramount interest from different reasons: beside their significant in vivo relevance, these products are often needed in the laboratory to study the response of selected cells to oxidized lipids. Unfortunately, the commercial availability of oxidized lipids is limited and scientists interested in studying the physiological impact of oxidized lipids are normally forced to prepare the required compounds by themselves. We will show here that chain-shortened products of oxidized phosphatidylcholines (PCs) such as aldehydes and carboxylic acids can be easily (and in nearly quantitative yields) generated by the Fenton reaction (H2O2+Fe(2+)) or the KMnO4-induced oxidation of the PC. Using the Fenton reaction and physiological saline, chlorinated oxidation products such as chlorohydrins are also readily available. Additionally, it will be shown that preparative thin-layer chromatography (TLC) is a convenient but simple method to isolate the individual oxidation products in reasonable yields and high purities: all relevant products could be successfully identified by matrix-assisted laser desorption and ionization (MALDI) mass spectrometry and the amounts of the oxidized products determined by a simple colorimetric assay.

Abstract
The honey bee (Apis mellifera) is characterized by a high degree of phenotypic plasticity of senescence-related processes, and has therefore become a model organism of gerontological research. Sperm of honey bee drones can remain fertile for several years within the storage organ of queens. The reason for this longevity is unknown, but the suppression of lipid peroxidation seems to play a decisive role. Here, we examined the questions of whether spermatheca- and in vitro-stored honey bee sperm are indeed resistant to lipid peroxidation, and whether the nature of sperm lipids could explain this resistance. The lipid composition of bee sperm was determined by matrix-assisted laser desorption and ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) combined with thin-layer chromatography (TLC). The positive ion mass spectra of drone sperm lipids are dominated by two glycerophosphocholine (GPC) species, although small amounts of sphingomyelins (SM) and glycerophosphoethanolamines (GPE) are also detectable after TLC. Alkyl/acyl and alkenyl/acyl compounds of GPC, and alkyl/acyl as well as diacyl compounds of GPE were detected containing oleyl, oleoyl, palmityl and palmitoyl as the most abundant residues. Assignments of all compounds have been additionally verified by enzymatic digestion and exposition to HCl. During incubation of sperm in the presence of air, characteristic lipid oxidation products such as lysophosphatidylcholine (LPC) appear. Inside the spermatheca, however, sperm lipids are obviously protected from oxidation and their composition does not change, even if they are stored over years. Our data support the view that the membrane composition of honey bee sperm could help to explain the extraordinary longevity of these cells.

Abstract
Oxidation processes of lipids are of paramount interest from many viewpoints. For instance, oxidation processes are highly important under in vivo conditions because molecules with regulatory functions are generated by oxidation of lipids or free fatty acids. Additionally, many inflammatory diseases are accompanied by lipid oxidation and, therefore, oxidation products are also useful disease (bio)markers. Thus, there is also considerable interest in methods of (oxidized) lipid analysis. Nowadays, soft ionization mass spectrometric (MS) methods are regularly used to study oxidative lipid modifications due to their high sensitivities and the extreme mass resolution. Although electrospray ionization (ESI) MS is so far most popular, applications of matrix-assisted laser desorption and ionization (MALDI) MS are increasing. This review aims to summarize the so far available data on MALDI analyses of oxidized lipids. In addition to model systems, special attention will be paid to the monitoring of oxidized lipids under in vivo conditions, particularly the oxidation of (human) lipoproteins. It is not the aim of this review to praise MALDI as the "best" method but to provide a critical survey of the advantages and drawbacks of this method.
