Abstract
Biomimetic models are valuable platforms to improve our knowledge on the molecular mechanisms governing membrane-driven processes in (patho)physiological conditions, including membrane permeability, transport, and fusion. However, current membrane models are over simplistic and do not include the membrane’s lipid remodelling in response to extracellular stimuli. Our study describes the synthesis of glycated dimyristoyl-phosphatidylethanolamine (DMPE-glyc), which was structurally characterised by mass spectrometry (ESI-MS) and quantified by NMR spectroscopy to be further incorporated in a complex phospholipid (PL) membrane model enriched in cholesterol (Chol) and (glyco)sphingolipids (GSL) designed to mimic epithelial membranes (PL/Chol/GSL) under hyperglycaemia conditions. Characterisation of synthesised DMPE-glyc adducts by tandem mass spectrometry (ESI-MS/MS) show that synthetic DMPE-glyc adducts correspond to Amadori products and quantification by 1H NMR spectroscopy show that the yield of glycation reaction was 8%. The biophysical characterisation of the epithelial membrane model shows that excess glucose alters the thermotropic behaviour and fluidity of epithelial membrane models likely to impact permeability of solutes. The epithelial membrane models developed to mimic normo- and hyperglycaemic scenarios are the basis to investigate (poly)phenol-lipid and drug–membrane interactions crucial in nutrition, pharmaceutics, structural biochemistry, and medicinal chemistry.

Abstract
Glycated lipids are formed by a Maillard reaction between the aldehyde group of a reducing sugar with the free amino group of an amino-lipid. The formation and accumulation of glycated lipids are closely related to the prognosis of diabetes, vascular disease, and cancer. However, it is not clear whether food-derived glycated lipids pose a direct threat to the human body. In this review, potentially harmful effect, distribution, formation environment and mechanism, and determination and inhibitory methods of glycated lipids are presented. Future research directions for the study of food-derived glycated lipids include: (1) understanding their digestion, absorption, and metabolism in the human body; (2) expanding the available database for associated risk assessment; (3) relating their formation mechanism to food production processes; (4) revealing the formation mechanism of food-derived glycated lipids; (5) developing rapid, reliable, and inexpensive determination methods for the compounds in different foods; and (6) seeking effective inhibitors. This review will contribute to the final control of food-derived glycated lipids.

Abstract
Competition between viruses and Wolbachia for host lipids is a proposed mechanism of Wolbachia-mediated virus blocking in insects. Yet, the metabolomic interaction between virus and symbiont within the mosquito has not been clearly defined. We compare the lipid profiles of Aedes aegypti mosquitoes bearing mono- or dual-infections of the Wolbachia wMel strain and dengue virus serotype 3 (DENV3). We found metabolic signatures of infection-induced intracellular events but little evidence to support direct competition between Wolbachia and virus for host lipids. Lipid profiles of dual-infected mosquitoes resemble those of DENV3 mono-infected mosquitoes, suggesting virus-driven modulation dominates over that of Wolbachia. Interestingly, knockdown of key metabolic enzymes suggests cardiolipins are host factors for DENV3 and Wolbachia replication. These findings define the Wolbachia-DENV3 metabolic interaction as indirectly antagonistic, rather than directly competitive, and reveal new research avenues with respect to mosquito × virus interactions at the molecular level. Koh, Islam, Ye et al. describe lipid profiles of Aedes aegypti mosquitoes bearing mono- or dual-infections of Wolbachia (wMel) and dengue virus serotype 3 (DENV3), finding that virus modulation dominates the dual-infection lipid profile and that cardiolipins support DENV3 and Wolbachia replication. This study suggests that direct competition for lipids do not underlie Wolbachia-mediated virus blocking.

Analysis of oxidised and glycated aminophospholipids: Complete structural characterisation by C30 liquid chromatography-high resolution tandem mass spectrometry. Free Radic Biol Med 2019; 144:144-155. [PMID: 31150763 DOI: 10.1016/j.freeradbiomed.2019.05.025] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 05/14/2019] [Accepted: 05/22/2019] [Indexed: 12/19/2022]
Abstract
The aminophospholipids (APL), phosphatidylethanolamine (PE) and phosphatidylserine (PS) are widely present in cell membranes and lipoproteins. Glucose and reactive oxygen species (ROS), such as the hydroxyl radical (•OH), can react with APL leading to an array of oxidised, glycated and glycoxidised derivatives. Modified APL have been implicated in inflammatory diseases and diabetes, and were identified as signalling molecules regulating cell death. However, the biological relevance of these molecules has not been completely established, since they are present in very low amounts, and new sensitive methodologies are needed to detect them in biological systems. Few studies have focused on the characterisation of APL modifications using liquid chromatography-tandem mass spectrometry (LC-MS/MS), mainly using C5 or C18 reversed phase (RP) columns. In the present study, we propose a new analytical approach for the characterisation of complex mixtures of oxidised, glycated and glycoxidised PE and PS. This LC approach was based on a reversed-phase C30 column combined with high-resolution MS, and higher energy C-trap dissociation (HCD) MS/MS. C30 RP-LC separated short and long fatty acyl oxidation products, along with glycoxidised APL bearing oxidative modifications on the glucose moiety and the fatty acyl chains. Functional isomers (e.g. hydroxy-hydroperoxy-APL and tri-hydroxy-APL) and positional isomers (e.g. 9-hydroxy-APL and 13-hydroxy-APL) were also discriminated by the method. HCD fragmentation patterns allowed unequivocal structural characterisation of the modified APL, and are translatable into targeted MS/MS fingerprinting of the modified derivatives in biological samples.

Abstract
The biological functions of modified aminophospholipids (APL) have become a topic of interest during the last two decades, and distinct roles have been found for these biomolecules in both physiological and pathological contexts. Modifications of APL include oxidation, glycation, and adduction to electrophilic aldehydes, altogether contributing to a high structural variability of modified APL. An outstanding technique used in this challenging field is mass spectrometry (MS). MS has been widely used to unveil modified APL of biological interest, mainly when associated with soft ionization methods (electrospray and matrix-assisted laser desorption ionization) and coupled with separation techniques as liquid chromatography. This review summarizes the biological roles and the chemical mechanisms underlying APL modifications, and comprehensively reviews the current MS-based knowledge that has been gathered until now for their analysis. The interpretation of the MS data obtained by in vitro-identification studies is explained in detail. The perspective of an analytical detection of modified APL in clinical samples is explored, highlighting the fundamental role of MS in unveiling APL modifications and their relevance in pathophysiology.

Abstract
Nonenzymatic glycation of lipids plays an important role in several physiological and pathological processes, such as normal aging and complications of diabetes mellitus. To develop liquid chromatography coupled with mass spectrometric (LC-MS) methods for accurate analysis of Amadori compound-glycated lipids from biological samples, it is essential to obtain isotope-labeled Amadori-lipid standards. Herein, we report optimized methods for the preparation of six stable isotope-labeled Amadori-glycated lipid standards covering four types of lipids, including [13C6]Amadori-phosphatidyl ethanolamine (PE), -phosphatidyl serine (PS), -LysoPE, and -LysoPS. Optimal conditions for the synthesis and purification of these four types of Amadori-glycated lipids were detailed in this study. LC-MS and LC-UV analyses showed that destination products were highly purified (>95%). Accurate mass and MS/MS fragmentation in both positive- and negative-ion modes further validated the identification of these six synthetic [13C6]Amadori-glycated lipid standards. Successful preparation of these highly purified isotope-labeled standards makes it possible to develop targeted LC-MS/MS methods for accurate analysis of Amadori-glycated phospholipids from biological samples.

Abstract
The Maillard reaction is a nonenzymatic glycation reaction between a reducing sugar and a free amino group, known to naturally occur during heat processing of food. In this study, we especially focused on phosphatidylethanolamine (PE)-linked Amadori products (Amadori-PE) in powdered milk, since the analysis of these products at the molecular species level has not yet been evaluated. Analysis of Amadori-PE was conducted by using liquid chromatography-tandem mass spectrometry in three different modes. The main Amadori-PE species in a powdered milk sample were first identified as 34:1, 36:1, 36:2 and 36:3 in the total ion current mode. Additionally, by using the characteristic product ions observed in the presence of sodium, we quantified the main Amadori-PE species in the multiple reaction monitoring mode, and evaluated their total concentrations in the precursor ion scan (PIS) mode for the first time. Powdered milk contained much Amadori-PE with concentrations ranging from 4.3 to 8239 mg/100 g, quantified by the PIS mode. The newly developed methods represent powerful tools for detailed analysis of glycated lipids including Amadori-PE in powdered milk, which may further be applied to research relating to infant food and nutrition.

Abstract
Food allergens have a notable potential to induce various health concerns in susceptible individuals. The majority of allergenic foods are usually subjected to thermal processing prior to their consumption. However, during thermal processing and long storage of foods, Maillard reaction (MR) often takes place. The MR is a non-enzymatic glycation reaction between the carbonyl group of reducing sugars and compounds having free amino groups. MR may sometimes be beneficial by damaging epitope of allergens and reducing allergenic potential, while exacerbation in allergic reactions may also occur due to changes in the motifs of epitopes or neoallergen generation. Apart from these modulations, non-enzymatic glycation can also modify the food protein(s) with various type of advance glycation end products (AGEs) such as Nϵ-(carboxymethyl-)lysine (CML), pentosidine, pyrraline, and methylglyoxal-H1 derived from MR. These Maillard products may act as immunogen by inducing the activation and proliferation of various immune cells. Literature is available to understand pathogenesis of glycation in the context of various diseases but there is hardly any review that can provide a thorough insight on the impact of glycation in food allergy. Therefore, present review explores the pathogenesis with special reference to food allergy caused by non-enzymatic glycation as well as AGEs.

Abstract
![]()
Oxidation of docosahexaenoate phospholipids
produces 4-hydroxy-7-oxo-hept-5-eonyl
phospholipids (HOHA-PLs) that react with protein lysyl ε-amino
residues to generate 2-ω-carboxyethylpyrrole (CEP) derivatives,
endogenous factors that induce angiogenesis in the retina and tumors.
It seemed likely, but remained unproven, that HOHA-PLs react with
ethanolamine phospholipids (EPs) in vivo to generate
CEP-EPs. We now show that CEP-EPs are present in human blood at 4.6-fold
higher levels in age-related macular degeneration plasma than in normal
plasma. We also show that CEP-EPs are pro-angiogenic, inducing tube
formation by human umbilical vein endothelial cells by activating
Toll-like receptor 2. CEP-EP levels may be a useful biomarker for
clinical assessment of AMD risk and CEP-associated tumor progression
and a tool for monitoring the efficacy of therapeutic interventions.

Abstract
In foodstuffs, one of the main factors inducing modifications in phospholipids (PLs) structure is the heat treatment. Among PLs, only phosphatidylethanolamines and phosphatidylserines, due to their free amino group, can be involved in Maillard reaction and can form adducts with reducing sugars, besides other by-products called advanced glycation end-products. To date, glycated lipid products are less characterized in comparison to proteins. The aim of this work was to develop a novel, rapid and sensitive extraction protocol for the detection and characterization of modified PLs (glycated and oxidized) by means of matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS). At first, to investigate the formation of glycated and/or short chain by-products in different classes of PLs, representative standards were heated with or without sugar (lactose or glucose) and subjected to traditional lipid extraction methods as Bligh and Dyer and to the novel direct in matrix extraction (DIME) using 1,8-bis(dimethylamino)naphthalene as preconcentrating matrix. MALDI-MS analysis in negative ion mode allowed detecting glycation and oxidation products both on fatty acid and glucose moieties. Then, the procedure was successfully applied to different heat-treated and powdered samples (milk powders, pasteurized milk, ultra-high-temperature milk and soy flour) for the detection of modified PLs in complex foods. The currently developed DIME protocol could be a powerful tool for understanding lipid glycation also in biological samples.

Abstract
Peroxidation of membranes and lipoproteins converts "inert" phospholipids into a plethora of oxidatively modified phospholipids (oxPL) that can act as signaling molecules. In this review, we will discuss four major classes of oxPL: mildly oxygenated phospholipids, phospholipids with oxidatively truncated acyl chains, phospholipids with cyclized acyl chains, and phospholipids that have been oxidatively N-modified on their headgroups by reactive lipid species. For each class of oxPL we will review the chemical mechanisms of their formation, the evidence for their formation in biological samples, the biological activities and signaling pathways associated with them, and the catabolic pathways for their elimination. We will end by briefly highlighting some of the critical questions that remain about the role of oxPL in physiology and disease.

Abstract
Phosphatidylserine (PS) is an aminophospholipid that is prone to glycation. In oxidative conditions, glycated PS may lead to the formation of Amadori compounds and advanced glycated end products (AGEs), which are known to accumulate in diabetic patients. Nevertheless, there have been no studies that identified products from the oxidative reaction of glycated PS. In this study, glycated 1-palmitoyl-2-oleoyl-PS was synthesized and further oxidized by Fenton reagent. The AGES formed were structurally characterized by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in negative mode. The oxidation products from glycated PS that we have found include products arising from the oxidation of the fatty acyl chains (hydroperoxides, hydroxides and keto derivatives), and arising from oxidative cleavage of serine polar head and lyso-glycated PS. Oxidation in C6 of glucose lead to the formation of glucuronyl-PS. In addition, new products arising from oxidative cleavage of glucose moiety (between C1C2, C2C3 and C3C4 bonds) were identified as PS-AGES. The current findings add substantially to the best of our knowledge of PS glycoxidation products, opening new perspectives for the detection of these products in complex biological matrices.

Abstract
Non-enzymatic modification of aminophospholipids by lipid peroxidation-derived aldehydes and reducing sugars through carbonyl-amine reactions are thought to contribute to the age-related deterioration of cellular membranes and to the pathogenesis of diabetic complications. Much evidence demonstrates the modification of aminophospholipids by glycation, glycoxidation and lipoxidation reactions. Therefore, a number of early and advanced Maillard reaction-lipid products have been detected and quantified in different biological membranes. These modifications may be accumulated during aging and diabetes, introducing changes in cell membrane physico-chemical and biological properties.

Abstract
Lipid aldehydes generated by lipid peroxidation induce cell damage and inflammation. Recent evidence indicates that γ-ketoaldehydes (isolevuglandins, IsoLGs) form inflammatory mediators by modifying the ethanolamine headgroup of phosphatidylethanolamines (PEs). To determine if other species of aldehyde-modified PEs (al-PEs) with inflammatory bioactivity were generated by lipid peroxidation, we oxidized liposomes containing arachidonic acid and characterized the resulting products. We detected PE modified by IsoLGs, malondialdehyde (MDA), and 4-hydroxynonenal (HNE), as well as a novel series of N-acyl-PEs and N-carboxyacyl-PEs in these oxidized liposomes. These al-PEs were also detected in high-density lipoproteins exposed to myeloperoxidase. When we tested the ability of al-PEs to induce THP-1 monocyte adhesion to cultured endothelial cells, we found that PEs modified by MDA, HNE, and 4-oxononenal induced adhesion with potencies similar to those of PEs modified by IsoLGs (∼2μM). A commercially available medium-chain N-carboxyacyl-PE (C11:0CAPE) also stimulated adhesion, whereas C4:0CAPE and N-acyl-PEs did not. PEs modified by acrolein or by glucose were only partial agonists for adhesion. These studies indicate that lipid peroxidation generates a large family of al-PEs, many of which have the potential to drive inflammation.

Abstract
Lipid peroxidation generates a variety of lipid aldehydes, which have been recognized to modify protein and DNA, causing inflammation and cancer. However, recent studies demonstrate that phosphatidylethanolamine (PE) is a major target for these aldehydes, forming aldehyde-modified PEs (al-PEs) as a novel family of mediators for inflammation. This review summarizes our current understanding of these al-PEs, including formation, detection, structural characterization, physiological relevance and mechanism of action.

Abstract
Several lines of experimental data have highlighted a key role of Amadori-glycated phosphatidylethanolamine (Amadori-PE) in the development of diabetic complications. Recent epidemiological studies suggest that diabetes mellitus could be a risk factor for some cancers. A characteristic of cancer cells is their immortal phenotype, and the enzyme telomerase contributes to the infinite replicative potential of cancer cells. The purpose of this study was to obtain new information about the effect of Amadori-PE on the regulation of telomerase in PANC-1 human pancreatic carcinoma cells. Amadori-PE enhanced cellular telomerase in a time- and dose-dependent manner by up-regulating hTERT expression through induction of c-myc. These results provide experimental evidence for a novel role of Amadori-PE in linking diabetes and cancer.

Abstract
Proteins modifications in diabetes may lead to early glycation products (EGPs) as well as advanced glycation end products (AGEs). Whereas no extensive studies have been carried out to assess the role of EGPs in secondary complications of diabetes, numerous investigators have demonstrated the role of AGEs. Early glycation involves attachment of glucose on ε-NH2 of lysine residues of proteins leading to generation of the Amadori product (an early glycation species). This study reports the structural and immunological characterization of EGPs of HSA because we believe that during persistent hyperglycemia the HSA, one of the major blood proteins, can undergo fast glycation. Glucose mediated generation of EGPs of HSA was quantitated as Amadori products by NBT assay and authenticated by boronate affinity chromatography and LC/MS. Compared to native HSA changes in glycated-HSA were characterized by hyperchromicity, loss in fluorescence intensity and a new peak in the FTIR profile. Immunogenicity of native- and glycated-HSA was evaluated by inducing antibodies in rabbits. Results suggest generation of neo-epitopes on glycated-HSA rendering it highly immunogenic compared to native HSA. Quantization of EGPs of HSA by authentic antibodies against HSA-EGPs can be used as marker for early detection of the initiation/progression of secondary complications of diabetes.

Abstract
It has been demonstrated in vivo that lipid glycation products such as Amadori-glycated phosphatidylethanolamine (Amadori-PE) accumulate in the plasma of diabetic humans and animals, but how lipid glycation products are formed under hyperglycemic conditions are not clear. We sought to clarify the occurrence of lipid glycation and its relationships with lipid peroxidation and protein glycation during the development of hyperglycemia using the streptozotocin (STZ)-induced diabetic rat model. A significant increase in Amadori-PE was observed in STZ rats 7 days after STZ treatment, and Amadori-PE (especially 18:0-20:4 Amadori-PE) was found at high levels in the blood and in organs that are strongly affected by diabetes, such as the kidney. Significant changes in Amadori-PE appeared to occur prior to changes in levels of oxidized lipids, which increased after 21-28 days. In addition, accumulation of Nε-(carboxymethyl)lysine (CML), a protein glycation product, proceeded somewhat more slowly and moderately than that of Amadori-PE, suggesting that Amadori-PE and CML are early and advanced glycation products, respectively. Our results suggest that Amadori-PE may be a useful predictive marker for hyperglycemia, particularly in the early stages of diabetes. Similar speculations have been made from previous human studies, but this study provides a direct evidence to support the speculations in rat study.

Abstract
Recent instrumental analyses using a hybrid quadrupole/linear ion trap spectrometer in LC-MS/MS have demonstrated that the Maillard reaction progresses not only on proteins but also on amino residues of membrane lipids such as phosphatidylethanolamine (PE), thus forming Amadori-PE (deoxy-D: -fructosyl PE) as the principal products. The plasma Amadori-PE level is 0.08 mol% of the total PE in healthy subjects and 0.15-0.29 mol% in diabetic patients. Pyridoxal 5'-phosphate and pyridoxal are the most effective lipid glycation inhibitors, and the PE-pyridoxal 5'-phosphate adduct is detectable in human red blood cells. These findings are beneficial for developing a potential clinical marker for glycemic control as well as potential compounds to prevent the pathogenesis of diabetic complications and atherosclerosis. Glucose and other aldehydes, such as glyoxal, methylglyoxal, and glycolaldehyde, react with the amino residues of proteins to form Amadori products and Heynes rearrangement products. Because several advanced glycation end-product (AGE) inhibitors such as pyridoxamine and benfotiamine inhibit the development of retinopathy and neuropathy in streptozotocin (STZ)-induced diabetic rats, AGEs may play a role in the development of diabetic complications. In the present review, we describe the recent progress and future applications of the Maillard reaction research regarding lipid and protein modifications in diabetes and atherosclerosis.

Abstract
An amino group of phosphatidylethanolamine (PE) is considered as a target for nonenzymatic glycation, and the potential involvement of lipid glycation in the pathogenesis of diabetic complications has generated interest. However, unlike an early glycation product of PE (Amadori-PE), the occurrence and roles of advanced glycation end products of PE (AGE-PE) in vivo have been unclear. Here, we developed an LC-MS/MS method for the analysis of AGE-PE [carboxymethyl-PE (CM-PE) and carboxyethyl-PE (CE-PE)]. Collision-induced dissociation of CM-PE and CE-PE produced characteristic ions, permitting neutral loss scanning (NLS) and multiple reaction monitoring (MRM) of AGE-PE. By NLS analysis, a series of AGE-PE molecular species was detected in human erythrocytes and blood plasma. In LC-MS/MS analysis, MRM enabled the separation and determination of the predominant AGE-PE species. Between healthy subjects and diabetic patients, no significant differences were observed in AGE-PE concentrations in erythrocytes and plasma, whereas Amadori-PE concentrations were higher in diabetic patients. These results provide direct evidence for the presence of AGE-PE in human blood, and indicated that, compared with Amadori-PE, AGE-PE is less likely to be accumulated in diabetic blood. The presently developed LC-MS/MS method appears to be a powerful tool for understanding in vivo lipid glycation and its pathophysiological consequence.

Abstract
Non-enzymatic glycation of biomolecules has been implicated in the pathophysiology of aging and diabetes. Among the potential targets for glycation are biological membranes, characterized by a complex organization of lipids and proteins interacting and forming domains of different size and stability. In the present study, we analyse the effects of glycation on the interactions between membrane proteins and lipids. The phospholipid affinity for the transmembrane surface of the PMCA (plasma-membrane Ca(2+)-ATPase) was determined after incubating the protein or the phospholipids with glucose. Results show that the affinity between PMCA and the surrounding phospholipids decreases significantly after phosphospholipid glycation, but remains unmodified after glycation of the protein. Furthermore, phosphatidylethanolamine glycation decreases by approximately 30% the stability of PMCA against thermal denaturation, suggesting that glycated aminophospholipids induce a structural rearrangement in the protein that makes it more sensitive to thermal unfolding. We also verified that lipid glycation decreases the affinity of lipids for two other membrane proteins, suggesting that this effect might be common to membrane proteins. Extending these results to the in vivo situation, we can hypothesize that, under hyperglycaemic conditions, glycation of membrane lipids may cause a significant change in the structure and stability of membrane proteins, which may affect the normal functioning of membranes and therefore of cells.

Abstract
Glycation has been thought to participate in diabetic vascular diseases. However, there are no reports about the effects of lipid glycation on endothelial dysfunction. In this study, we have evaluated whether Amadori-glycated phosphatidylethanolamine (Amadori-PE), a lipid-linked glycation compound, affected proliferation, migration, and tube formation of cultured human umbilical vein endothelial cells. These three factors involved in angiogenesis were significantly stimulated by Amadori-PE at a low concentration of less than 5 microM. Furthermore, Amadori-PE also stimulated the secretion of matrix metalloproteinase-2 (MMP-2), a pivotal enzyme in the initial step of angiogenesis. Our results indicated for the first time that Amadori-PE would elicit vascular disease through angiogenic potency on endothelial cells, thereby playing an active part in the development and progression of diabetic microangiopathy.

Abstract
Peroxidized phospholipid-mediated cytotoxicity is involved in the pathophysiology of diseases [i.e., an abnormal increase of phosphatidylcholine hydroperoxide (PCOOH) in plasma of type 2 diabetic patients]. The PCOOH accumulation may relate to Amadori-glycated phosphatidylethanolamine (Amadori-PE; deoxy-D-fructosyl phosphatidylethanolamine), because Amadori-PE causes oxidative stress. However, the occurrence of lipid glycation products, including Amadori-PE, in vivo is still unclear. Consequently, we developed an analysis method of Amadori-PE using a quadrupole/linear ion-trap mass spectrometer, the Applied Biosystems QTRAP. In positive ion mode, collision-induced dissociation of Amadori-PE produced a well-characterized diglyceride ion ([M+H-303]+) permitting neutral loss scanning and multiple reaction monitoring (MRM). When lipid extract from diabetic plasma was infused directly into the QTRAP, Amadori-PE molecular species could be screened out by neutral loss scanning. Interfacing liquid chromatography with QTRAP mass spectrometry enabled the separation and determination of predominant plasma Amadori-PE species with sensitivity of approximately 0.1 pmol/injection in MRM. The plasma Amadori-PE level was 0.08 mol% of total PE in healthy subjects and 0.15-0.29 mol% in diabetic patients. Furthermore, plasma Amadori-PE levels were positively correlated with PCOOH (a maker for oxidative stress). These results show the involvement between lipid glycation and lipid peroxidation in diabetes pathogenesis.

Abstract
The object of this study was to examine the effect of elevated in vitro glucose concentrations on protein modification and functional changes in human erythrocytes. Groups were exposed to 5-45 mM glucose concentrations. The time effect of any changes was also evaluated. In erythrocyte ghosts, protein glycation and oxidation were evaluated using spectrophotometric methods. G-actin was measured by a DNase I inhibition assay in cell lysates. Erythrocyte deformability was assessed using a cell transit analyser. At 24 h, a significant protein oxidation (at 25 and 45 mM glucose; p < 0.05), and G-actin increase was observed for all concentrations (p < 0.05). At 48 h, a significant increase in glycation (25 and 45 mM glucose; p < 0.05), protein oxidation (p < 0.05), and G-actin (p < 0.05) was observed in all groups. A significant positive correlation was observed between glucose /protein oxidation, glucose/G-actin and protein oxidation/G-actin at 24 and 48 h. Our findings show that the oxidative effect of glucose on erythrocytes depends on concentration and incubation time. We also present the first evidence of increased G-actin in human erythrocytes exposed to high glucose concentrations as a diabetes model.

Abstract
Glycation has been implicated in the endothelial dysfunction that contributes to both diabetes- and aging-associated vascular complications. The aim of the present study was to determine whether Amadori-glycated phosphatidylethanolamine (Amadori-PE), a lipid-linked glycation compound that is formed at an increased rate in hyperglycemic states, affected proliferation, migration and tube formation of cultured human umbilical vein endothelial cells (HUVEC). Amadori-PE at a low concentration of less than 5 microM significantly enhanced these three factors involved in angiogenesis. Furthermore, stimulation of HUVEC with Amadori-PE resulted in secretion of matrix metalloproteinase 2 (MMP-2), a pivotal enzyme in the initial step of angiogenesis. Our results demonstrated for the first time that Amadori-PE may be an important compound that promotes vascular disease as a result of its angiogenic activity on endothelial cells. We also demonstrated that MMP-2 is a primary mediator of Amadori-PE-driven angiogenesis.

Abstract
Glycation (nonenzymatic glycosylation of proteins) is known to be increased as a result of hyperglycaemia in diabetes. Moreover, cell glutathione concentration has been found to be lower in diabetics and such depletion may impair the cell defence against toxic radical species. Ribose being a potent reducing sugar expected to be increased in cells of diabetics where the pentose phosphate pathway is enhanced, its putative condensation with glutathione was investigated. Reduced glutathione (GSH) was incubated with ribose and the structure of the resultant product was assessed by mass spectrometry, as well as the measurement of its remaining thiol group. A covalent reaction clearly occurred between the reducing sugar and GSH, to give an adduct named N-ribosyl-1-glutathione. This adduct appears to be the Amadori product resulting from the condensation of the primary amine group of GSH with the aldehyde group of ribose. Interestingly, the adduct could not be used as a proper substrate by glutathione peroxidase although it keeps its thiol group. We conclude that the coupling of GSH with a monosaccharide such as ribose might contribute to the decreased cell GSH and glutathione peroxidase activity observed in diabetics.

Abstract
While the Maillard reaction of amino acids and proteins as well as its consequences in vivo has been thoroughly investigated, little attention has so far been paid to the glycation of aminophospholipids such as phosphatidylethanolamine (PE) or phosphatidylserine (PS), which are essential for structure and functionality of biological membranes. PE-derived glucosylamines (Schiff-PEs) and aminoketoses (Amadori-PEs) have now for the first time been simultaneously identified and quantified in erythrocytes from diabetics and healthy individuals by liquid chromatography-electrospray mass spectrometry (LC-(ESI)MS). The amounts of glycated PE (gPE) were significantly higher in diabetics (0.18-34.2 mol% Schiff-PE and 0.047-0.375 mol% Amadori-PE) than in controls (0.12-3.99 mol% Schiff-PE and 0.018-0.055 mol% Amadori-PE). A positive correlation between fructosylated hemoglobin (HbA(1c)) and the gPE levels was established. No advanced glycation endproducts (AGEs) like 5-hydroxymethylpyrrole-2-carbaldehyde (pyrrole-PE), carboxymethyl (CM-PE), or carboxyethyl (CE-PE) derivatives were detected. To investigate the influence of gPE on lipid peroxidation of biological membranes, liposomes consisting of soy-PE and synthetically prepared Amadori-PE (16:0-16:0) were incubated for several days and the formation of oxidation products was monitored. It could be shown that Amadori-PE extensively promotes lipid peroxidation even in the absence of transition metal ions like Cu(2+) and Fe(3+). Oxidative damage to membrane lipids therefore is supposed to be at least partially caused by the glycation of aminophospholipids.

Abstract
This study for the first time confirmed the peroxidative role of the Amadori product derived from the glycation of phosphatidylethanolamine (PE), namely Amadori-PE. The product was synthesized from the reaction of dioleoyl PE with D-glucose, and then purified by a solid-phase extraction procedure, which was a key step in the next HPLC technique for the isolation of essentially pure Amadori-PE. When the synthetically prepared Amadori-PE was incubated with linoleic acid in the presence of Fe(3+) in micellar system, a remarkable formation of thiobarbituric acid reactive substances was observed together with increases in lipid hydroperoxides. In addition, the lipid peroxidation caused by Amadori-PE was effectively inhibited by superoxide dismutase, mannitol, catalase and metal chelator. These results indicated that Amadori-PE triggers oxidative modification of lipids via the generation of superoxide, and implied the involvement of 'lipid glycation' along with membrane lipid peroxidation in the pathogenesis of diabetes and aging.

Abstract
Phospholipid-linked glycation products are supposed to play an important role in lipid oxidation in vivo. Independent syntheses and unequivocal structural characterization are reported for the phosphatidyl ethanolamine (PE)-derived Amadori compound 4-hydroxy-4-oxo-1-[(palmitoyloxy)methyl]-9-(2,3,4,5-tetrahydrox ytetrahydro-2H-pyran-2-yl)-3,5-dioxa-8-aza-4lambda5-ph osphanon-1-yl palmitate, pyrrolecarbaldehyde 2-[[[2-[2-formyl-5-(hydroxymethyl)-1H-pyrrol-1-yl]ethoxy](hydroxy)phosph oryl]oxy]-1-[(palmitoyloxy)methyl]ethyl palmitate, the carboxymethyl (CM) derivative 7-hydroxy-7,13-dioxo-10-(palmitoyloxy)-6,8,12-trioxa-3-aza-+ ++7lambda5-phosphaoctacosan-1-oic acid, and the carboxyethyl (CE) derivative 7-hydroxy-2-methyl-7,13-dioxo-10-(palmitoyloxy)-6,8,12-trioxa++ +-3-aza-7lambda5-phosphaoctacosan-l-oic acid. With these reference compounds, a liquid chromatography-mass spectrometry (LCMS) method for the determination of such PE-linked Maillard products has been developed.

Abstract
While the Maillard reaction of free amino acids and proteins is a well-established process, no defined structures from the nonenzymatic browning of aminophospholipids in foodstuffs have been described so far. Phosphatidylethanolamine (PE)-linked glucosylamines (Schiff-PE), Amadori products (Amadori-PE), 5-hydroxymethylpyrrole-2-carbaldehydes (Pyrrole-PE), and carboxymethyl (CM-PE) as well as carboxyethyl (CE-PE) derivatives were detected and quantified by liquid chromatography- electrospray mass spectrometry (LC-(ESI)MS). Model incubations of soy-PE and D-glucose were employed to firmly establish the LC-(ESI)MS procedure. Analyses of spray-dried egg yolk powders and lecithin products derived therefrom show one-fourth of the native D-glucose content of egg yolk to be transformed to Amadori-PE, corresponding to a PE derivatization quota of 11-15.5 mol %. Schiff-PE and Pyrrole-PE were present only in low amounts, no CM-PE and CE-PE could be identified in any of the investigated samples. The high glycation rate of egg yolk PE will influence the emulsifying properties and perhaps even the oxidation resistance of the respective products.
