Abstract
Lactulosyllysine (LL) widely exists in thermally processed dairy products, while the metabolism and transformation of LL remain poorly understood. We aimed to elucidate the metabolic pathways of LL and its impact on body health by subjecting C57BL/6 mice to a short-term ll-fortified casein diet. Our findings indicated that casein-bound LL might be metabolized and transformed into 3-deoxyglucosone through fructosamine-3-kinase (FN3K) in vivo, which promoted α-dicarbonyl stress, ultimately leading to the formation of advanced glycation end products (AGEs) in various tissues/organs, accompanied by systemic inflammation. The levels of AGEs formation in tissues/organs at various stages of casein-bound LL intake exhibited dynamic changes, correlating with alterations in the expression of FN3K and α-dicarbonyl compounds metabolic detoxification enzymes. The negative effects induced by casein-bound LL cannot be fully reversed by switching to a standard diet for equal periods. Consumption of dairy products rich in LL raises concerns as a potential risk factor for healthy individuals.

Abstract
Reactive carbonyl species (RCS) such as methylglyoxal and glyoxal are potent glycolytic intermediates that extensively damage cellular biomolecules leading to genetic aberration and protein misfolding. Hence, RCS levels are crucial indicators in the progression of various pathological diseases. Besides the glyoxalase system, emerging studies report highly conserved DJ-1 superfamily proteins as critical regulators of RCS. DJ-1 superfamily proteins, including the human DJ-1, a genetic determinant of Parkinson's disease, possess diverse physiological functions paramount for combating multiple stressors. Although S. cerevisiae retains four DJ-1 orthologs (Hsp31, Hsp32, Hsp33, and Hsp34), their physiological relevance and collective requirement remain obscure. Here, we report for the first time that the yeast DJ-1 orthologs function as novel enzymes involved in the preferential scavenge of glyoxal and methylglyoxal, toxic metabolites, and genotoxic agents. Their collective loss stimulates chronic glycation of the proteome, and nucleic acids, inducing spectrum of genetic mutations and reduced mRNA translational efficiency. Furthermore, the Hsp31 paralogs efficiently repair severely glycated macromolecules derived from carbonyl modifications. Also, their absence elevates DNA damage response, making cells vulnerable to various genotoxins. Interestingly, yeast DJ-1 orthologs preserve functional mitochondrial content, maintain ATP levels, and redistribute into mitochondria to alleviate the glycation damage of macromolecules. Together, our study uncovers a novel glycation repair pathway in S. cerevisiae and a possible neuroprotective mechanism of how hDJ-1 confers mitochondrial health during glycation toxicity.

Abstract
Like humans, many felid species suffer from teratozoospermia and frequently produce low numbers of normal spermatozoa. Male fertility can be affected by oxidative and dicarbonyl stress. Because of the high level of glycolytic activity in testes, reactive dicarbonyl metabolites may arise as side-products of glycolysis; their generation is further promoted by oxidative stress. Alpha-oxoaldehydes, including methylglyoxal (MG), are reactive dicarbonyl metabolites and substrates for the formation of advanced glycation end products. Elevated levels of both may lead to dicarbonyl stress and cause cellular dysfunction. However, MG and other α-oxoaldehydes can be converted to less dangerous molecules via the glyoxalase pathway. In this pathway, α-oxoaldehydes react with glutathione (GSH), forming a thioacetal, which becomes metabolized by glyoxalase I (GLO I) to S-D-lactoyl-glutathione (SLG). Glyoxalase II (GLO II) converts SLG to d-lactate upon the release of GSH. Nothing is known about the glyoxalase system in the feline testis and its capacity to mitigate an excess of dicarbonyl metabolites. To study whether GLO I and GLO II are present and have a specific function in the testis of the domestic cat, the gene expression of both enzymes were analyzed in testis samples of different developmental stages (prepubertal, pubertal, postpubertal). Furthermore, the presence of GLO I and GLO II proteins was investigated via immunohistochemistry. The GLO I gene expression does not change between developmental stages. Immunohistochemistry revealed strong signals for GLO I in the cytoplasm and nuclei of Sertoli and Leydig cells during all developmental stages. GLO I was described as catalyzing the rate-limiting step in the glyoxalase pathway. This implies a function on the part of this enzyme of sustaining the homeostasis of somatic testicular cells. For GLO II, we observed stage-dependent mRNA expression, which was significantly increased after puberty. In accordance with this observation, clear immunohistochemical GLO II signals were observed in nuclei of individual germ cells. The most intense signals were visible in spermatocytes. The different localizations of the strong GLO I and GLO II signals indicate that GLO II, in addition to the classical glyoxalase pathway, may have additional functions in meiotic germ cells, for example, providing lactate as an energy substrate and/or GSH as an antioxidant. Moreover, protein functions may be modulated via S-glutathionylation.

Abstract
Methylglyoxal (MGO) is a reactive glucose metabolite linked to diabetic cardiovascular disease (CVD). MGO levels surge during intermittent hyperglycemia. We hypothesize that these MGO spikes contribute to atherosclerosis, and that pyridoxamine as a MGO quencher prevents this injury. To study this, we intravenously injected normoglycemic 8-week old male C57Bl6 ApoE-/- mice with normal saline (NS, n = 10) or 25 µg MGO for 10 consecutive weeks (MGOiv, n = 11) with or without 1 g/L pyridoxamine (MGOiv+PD, n = 11) in the drinking water. We measured circulating immune cells by flow cytometry. We quantified aortic arch lesion area in aortic roots after Sudan-black staining. We quantified the expression of inflammatory genes in the aorta by qPCR. Intermittent MGO spikes weekly increased atherosclerotic burden in the arch 1.8-fold (NS: 0.9 ± 0.1 vs 1.6 ± 0.2 %), and this was prevented by pyridoxamine (0.8 ± 0.1 %). MGOiv spikes increased circulating neutrophils and monocytes (2-fold relative to NS) and the expression of ICAM (3-fold), RAGE (5-fold), S100A9 (2-fold) and MCP1 (2-fold). All these changes were attenuated by pyridoxamine. This study suggests that MGO spikes damages the vasculature independently of plasma glucose levels. Pyridoxamine and potentially other approaches to reduce MGO may prevent excess cardiovascular risk in diabetes.

Abstract
Elevated methylglyoxal levels contribute to ammonium-induced growth disorders in Arabidopsis thaliana. Methylglyoxal detoxification pathway limitation, mainly the glyoxalase I activity, leads to enhanced sensitivity of plants to ammonium nutrition. Ammonium applied to plants as the exclusive source of nitrogen often triggers multiple phenotypic effects, with severe growth inhibition being the most prominent symptom. Glycolytic flux increase, leading to overproduction of its toxic by-product methylglyoxal (MG), is one of the major metabolic consequences of long-term ammonium nutrition. This study aimed to evaluate the influence of MG metabolism on ammonium-dependent growth restriction in Arabidopsis thaliana plants. As the level of MG in plant cells is maintained by the glyoxalase (GLX) system, we analyzed MG-related metabolism in plants with a dysfunctional glyoxalase pathway. We report that MG detoxification, based on glutathione-dependent glyoxalases, is crucial for plants exposed to ammonium nutrition, and its essential role in ammonium sensitivity relays on glyoxalase I (GLXI) activity. Our results indicated that the accumulation of MG-derived advanced glycation end products significantly contributes to the incidence of ammonium toxicity symptoms. Using A. thaliana frostbite1 as a model plant that overcomes growth repression on ammonium, we have shown that its resistance to enhanced MG levels is based on increased GLXI activity and tolerance to elevated MG-derived advanced glycation end-product (MAGE) levels. Furthermore, our results show that glyoxalase pathway activity strongly affects cellular antioxidative systems. Under stress conditions, the disruption of the MG detoxification pathway limits the functioning of antioxidant defense. However, under optimal growth conditions, a defect in the MG detoxification route results in the activation of antioxidative systems.

Abstract
Agrochemicals can adversely affect biodiversity, environment and human health, and commonly occur in mixtures with poorly characterized toxic mechanisms and health hazards. Here, we evaluated the individual and mixture toxicities of Roundup and chlorpyrifos in environmentally relevant concentrations to zebrafish using molecular and biochemical indices. Studied pesticides alone and in combination caused depletion of total antioxidant capacity and cellular thiols, overproduction of ROS, accumulation of oxidative lesions and elevated DNA damage in zebrafish liver. Notably, low concentration of Roundup induced a hormesis-like effect by stimulating the protective cellular mechanisms. Chlorpyrifos showed stronger prooxidant effects than Roundup and additionally caused nitrosative and carbonyl stress in zebrafish. At the organismal level, studied pesticides and their mixtures induced hepato- and neurotoxicity. The effects of the studied pesticides on biomarkers of apoptosis, endocrine disruption and immune disorders were generally weak and inconsistent. The multibiomarker assessment showed that chlorpyrifos is considerably more toxic than Roundup to zebrafish. The toxic effects of the pesticide mixtures were mostly driven by chlorpyrifos, with minimal or mitigating effects of Roundup addition. These findings elucidate the toxic mechanisms of common pesticides in a model vertebrate and demonstrate that health hazards of pesticide mixtures cannot be predicted from the effects of single pesticides.

Abstract
Advanced glycation end products (AGEs) and their precursors, referred to as glycation products, are a heterogenous group of compounds being associated with adverse health effects. They are formed endogenously and in exogenous sources including food. This review investigates the roles of endogenously versus exogenously formed glycation products in the potential induction of adverse health effects, focusing on differences in toxicokinetics and toxicodynamics, which appeared to differ depending on the molecular mass of the glycation product. Based on the available data, exogenous low molecular mass (LMM) glycation products seem to be bioavailable and to contribute to dicarbonyl stress and protein cross-linking resulting in formation of endogenous AGEs. Bioavailability of exogenous high molecular mass (HMM) glycation products appears limited, while these bind to the AGE receptor (RAGE), initiating adverse health effects. Together, this suggests that RAGE-binding in relevant tissues will more likely result from endogenously formed glycation products. Effects on gut microbiota induced by glycation products is proposed as a third mode of action. Overall, studies which better discriminate between LMM and HMM glycation products and between endogenous and exogenous formation are needed to further elucidate the contributions of these different types and sources of glycation products to the ultimate biological effects.

Abstract
AIMS Dicarbonyl compounds contribute to the formation of advanced glycation endproducts (AGEs) and the development of insulin resistance and vascular complications. Dicarbonyl stress may already be detrimental in obesity. We evaluated whether diet-induced weight loss can effectively reverse dicarbonyl stress in abdominally obese men. MATERIALS AND METHODS Plasma samples were collected from lean (n = 25) and abdominally obese men (n = 52) in the fasting state, and during a mixed meal test (MMT). Abdominally obese men were randomized to 8 weeks of dietary weight loss or habitual diet, followed by a second MMT. The α-dicarbonyls methylglyoxal (MGO), glyoxal (GO) and 3-deoxyglucosone (3-DG) and AGEs were measured by UPLC-MS/MS. Skin autofluorescence (SAF) was measured using the AGE reader. T-tests were used for the cross-sectional analysis and ANCOVA to assess the treatment effect. RESULTS Postprandial glucose, MGO and 3-DG concentrations were higher in obese men as compared to lean men (p < 0.05 for all). Fasting dicarbonyls, AGEs, and SAF were not different between lean and obese men. After the weight loss intervention, fasting MGO levels tended to decrease by 25 nmol/L (95%-CI: -51-0.5; p = 0.054). Postprandial dicarbonyls were decreased after weight loss as compared to the control group: iAUC of MGO decreased by 57% (5280 nmol/L∙min; 95%-CI: 33-10526; p = 0.049), of GO by 66% (11,329 nmol/L∙min; 95%-CI: 495-22162; p = 0.041), and of 3-DG by 45% (20,175 nmol/L∙min; 95%-CI: 5351-35000; p = 0.009). AGEs and SAF did not change significantly after weight loss. CONCLUSION Abdominal obesity is characterized by increased postprandial dicarbonyl stress, which can be reduced by a weight loss intervention. Registered under ClinicalTrials.gov Identifier no. NCT01675401.

Abstract
AIMS/HYPOTHESIS Reactive α-dicarbonyl compounds are major precursors of AGEs and may lead to glycation of circulating and/or cell-associated complement regulators. Glycation of complement regulatory proteins can influence their capacity to inhibit complement activation. We investigated, in a human cohort, whether greater dicarbonyl stress was associated with more complement activation. METHODS Circulating concentrations of dicarbonyl stress markers, i.e. α-dicarbonyls (methylglyoxal [MGO], glyoxal [GO] and 3-deoxyglucosone [3-DG]), and free AGEs (Nε-(carboxymethyl)lysine [CML], Nε-(carboxyethyl)lysine [CEL] and Nδ-(5-hydro-5-methyl-4-imidazolon-2-yl)-ornithine [MG-H1]), and protein-bound AGEs (CML, CEL, pentosidine), as well as the complement activation products C3a and soluble C5b-9 (sC5b-9), were measured in 530 participants (59.5 ± 7.0 years [mean ± SD], 61% men) of the Cohort on Diabetes and Atherosclerosis Maastricht (CODAM) study. Multiple linear regression analyses were used to investigate the associations between dicarbonyl stress (standardised) and complement activation (standardised) with adjustment of potential confounders, including age, sex, lifestyle, use of medication and markers of obesity. In addition, the associations of two potentially functional polymorphisms (rs1049346, rs2736654) in the gene encoding glyoxalase 1 (GLO1), the rate-limiting detoxifying enzyme for MGO, with C3a and sC5b-9 (all standardized) were evaluated. RESULTS After adjustment for potential confounders, plasma concentration of the dicarbonyl GO was inversely associated with sC5b-9 (β -0.12 [95% CI -0.21, -0.02]) and the protein-bound AGE CEL was inversely associated with C3a (-0.17 [-0.25, -0.08]). In contrast, the protein-bound AGE pentosidine was positively associated with sC5b-9 (0.15 [0.05, 0.24]). No associations were observed for other α-dicarbonyls and other free or protein-bound AGEs with C3a or sC5b-9. Individuals with the AG and AA genotype of rs1049346 had, on average, 0.32 and 0.40 SD lower plasma concentrations of sC5b-9 than those with the GG genotype, while concentrations of C3a did not differ significantly between rs1049346 genotypes. GLO1 rs2736654 was not associated with either C3a or sC5b-9. CONCLUSIONS/INTERPRETATION Plasma concentrations of dicarbonyl stress markers showed distinct associations with complement activation products: some of them were inversely associated with either C3a or sC5b-9, while protein-bound pentosidine was consistently and positively associated with sC5b-9. This suggests different biological relationships of individual dicarbonyl stress markers with complement activation.

Abstract
Methylglyoxal (MG) is generated from glycolytic metabolites, lipid peroxidation, glucose autooxidation and protein glycation. It is a prooxidant inducing oxidative stress and formation of advanced glycation end products (AGE). Effect of carnosine (CAR) as an antioxidant on toxicity due to MG has generated interest. In this study, rats were given incrementally increased doses (100-300 mg/kg) of MG in drinking water for ten weeks. CAR (250 mg/kg i.p.) was administered with MG. Plasma thiobarbituric reactive substances (TBARS), protein carbonyl (PC), advanced oxidation protein products (AOPP) and AGE levels were elevated by MG, and CAR decreased PC, AOPP and AGE levels. MG increased liver reactive oxygen species (ROS), TBARS, PC and AOPP levels, which were decreased by CAR. Thus, in vivo role of CAR on chronic MG administration was observed to suppress the generated hepatic and plasma oxidative stress.

Abstract
Epigallocatechin 3-gallate (EGCG) from green tea may reduce plasma glucose and alleviate complications of diabetes by attenuating advanced glycation end products (AGEs) formation. We hypothesized that EGCG would mitigate AGEs formation via activating the nuclear factor erythroid-2-related-factor-2 (Nrf2) pathway in a mouse model of high fat diet-induced obesity. Dietary EGCG was tested in C57BL/6 mice that were placed on a high-fat diet with or without ECGC for 17 weeks and compared to a control group placed on low-fat diet for the same period. Weight gain and fasting blood glucose were measured throughout the study duration. Supplementation of high fat diet with dietary EGCG significantly reduced weight gain, plasma glucose, insulin level, liver and kidney weight. EGCG administration also decreased the levels of AGEs in both plasma and liver while inhibiting the receptor for AGE (RAGE) expression of, activating Nrf2 and enhancing GSH/GSSG ratio compared to mice on high fat diet without added EGCG. This study demonstrated that EGCG has the potential to help control hyperglycemia, reduce weight, and alleviate diabetes complications.

Abstract
BACKGROUND Proteins in human tissues and body fluids continually undergo spontaneous oxidation and glycation reactions forming low levels of oxidation and glycation adduct residues. Proteolysis of oxidised and glycated proteins releases oxidised and glycated amino acids which, if they cannot be repaired, are excreted in urine. SCOPE OF REVIEW In this review we give a brief background to the classification, formation and processing of oxidised and glycated proteins in the clinical setting. We then describe the application of stable isotopic dilution analysis liquid chromatography-tandem mass spectrometry (LC-MS/MS) for measurement of oxidative and glycation damage to proteins in clinical studies, sources of error in pre-analytic processing, corroboration with other techniques - including how this may be improved - and a systems approach to protein damage analysis for improved surety of analyte estimations. MAJOR CONCLUSIONS Stable isotopic dilution analysis LC-MS/MS provides a robust reference method for measurement of protein oxidation and glycation adducts. Optimised pre-analytic processing of samples and LC-MS/MS analysis procedures are required to achieve this. GENERAL SIGNIFICANCE Quantitative measurement of protein oxidation and glycation adducts provides information on level of exposure to potentially damaging protein modifications, protein inactivation in ageing and disease, metabolic control, protein turnover, renal function and other aspects of body function. Reliable and clinically assessable analysis is required for translation of measurement to clinical diagnostic use. Stable isotopic dilution analysis LC-MS/MS provides a "gold standard" approach and reference methodology to which other higher throughput methods such as immunoassay and indirect methods are preferably corroborated by researchers and those commercialising diagnostic kits and reagents.
