Abstract
Advanced glycation end products (AGEs) are formed by a series of chemical reactions of amino acids, peptides, proteins, and ketones at normal temperature or heated non-enzymatic conditions. A large amount of AGEs derived from Maillard Reaction (MR) during the process of food heat-processing. After oral intake, dietary AGEs are converted into biological AGEs through digestion and absorption, and accumulated in almost all organs. The safety and health risk of dietary AGEs have attracted wide attention. Increasing evidence have shown that uptake of dietary AGEs is closely related to the occurrence of many chronic diseases, such as diabetes, chronic kidney disease, osteoporosis, and Alzheimer's disease. This review summarized the most updated information of production, bio-transport in vivo, detection technologies, and physiological toxicity of dietary AGEs, and also discussed approaches to inhibit dietary AGEs generation. Impressively, the future opportunities and challenges on the detection, toxicity, and inhibition of dietary AGEs are raised.

Abstract
The engineering of synthetic metabolic routes can provide valuable lessons on the roles of different biochemical constraints in shaping pathway activity. In this study, we designed and engineered a novel glycerol assimilation pathway in Escherichia coli. While the synthetic pathway was based only on well-characterized endogenous reactions, we were not able to establish robust growth using standard concentrations of glycerol. Long-term evolution failed to improve growth via the pathway, indicating that this limitation was not regulatory but rather relates to fundamental aspects of cellular metabolism. We show that the activity of the synthetic pathway is fully controlled by three key physicochemical constraints: thermodynamics, kinetics and metabolite toxicity. Overcoming a thermodynamic barrier at the beginning of the pathway requires high glycerol concentrations. A kinetic barrier leads to a Monod-like growth dependency on substrate concentration, but with a very high substrate saturation constant. Finally, the flat thermodynamic profile of the pathway enforces a pseudoequilibrium between glycerol and the reactive intermediate dihydroxyacetone, which inhibits growth when the feedstock concentration surpasses 1000 mm. Overall, this study serves to demonstrate the use of synthetic biology to elucidate key design principles of cellular metabolism.

Abstract
The formation of placenta at the beginning of pregnancy and its separation at parturition require not only deep remodelling of extracellular matrix, which mainly consists of proteins conjugated with sugar moieties, but also the cooperation with cells from both maternal and foetal parts of placenta. The aim of the study was to compare the patterns of selected conjugated proteins with sugar moieties between pregnant and term placenta as well as between released and retained placenta in cows. Placental samples from healthy pregnant cows (3-5 months of pregnancy) were collected at a slaughterhouse (n = 6), and parturient samples were collected during caesarean section at term and retrospectively divided into retained (n = 6) and released (n = 6). The pattern of selected sugar moieties conjugated with proteins was detected by use of lectin blotting with Phaseolus Vulgaris leucoagglutinin, Maackia Amurensis and Sambucus Nigra (Elderberry). The comparison and analysis of obtained band patterns showed differences between their number, molecular weight and abundance related to the intensity of staining. Samples from 3 to 4 months showed similarities, while at the 5th month, clear differences were visible in all 3 lectins, which were used in this study. Samples from retained/released placenta expressed significant differences in PHA-L and SNA pattern in the foetal part. Obtained results indicate that the development of placenta related to extracellular matrix and accompanying cells from both sides of placenta shows dynamic changes during pregnancy. Moreover, in the case of animals with the retention of foetal membranes the patterns of proteins conjugated with sugar moieties are altered, suggesting that the changes in extracellular matrix metabolism can be involved in the attachment and detachment of the placenta in cows.

Abstract
Reverse cholesterol transport (RCT), which is intimately linked to high-density lipoproteins (HDLs), plays a key role in cholesterol homeostasis and the prevention of atherosclerosis. The goal of the present study was to investigate the effect of aging and advanced glycation end products (AGEs) on RCT as well as on other factors that may affect the antiatherogenic property of HDLs. The transfer of macrophage-derived cholesterol to the plasma and liver and then to the feces for elimination was significantly lower in aged mice than in young mice. Chronic injection of d -galactose (D-gal) or AGEs also significantly reduced RCT (65.3% reduction in [3H]cholesterol levels in the plasma of D-gal-treated mice after 48 h compared with control mice, P < 0.01). The injection of both D-gal and aminoguanidine hydrochloride increased [3H]cholesterol levels in the plasma, although the levels were lower than those of control mice. The in vitro incubation of HDLs with dicarbonyl compounds increased the carbonyl and conjugated diene content of HDLs and significantly reduced PON1 paraoxonase activity (87.4% lower than control HDLs, P < 0.0001). Treating J774A.1 macrophages with glycated fetal bovine serum increased carbonyl formation (39.5% increase, P < 0.003) and reduced ABCA1 protein expression and the capacity of macrophages to liberate cholesterol (69.1% decrease, P < 0.0001). Our results showed, for the first time, that RCT is altered with aging and that AGEs contribute significantly to this alteration.

Abstract
Diabetes is a debilitating, life-threatening disease accounting in 2015 for the death of 5 million people worldwide. According to new estimations, 415 million adults currently suffer from the disease, and this number is expected to rise to 642 million by 2040. High glucose blood levels also affect the skin among systemic organs, and skin disorders can often predict the onset of this metabolic disorder. In this review, we address the pathomechanistic effects of diabetes on the skin and give an overview on the most common skin diseases associated with diabetes.

Abstract
Glycolaldehyde induces endoplasmic reticulum stress in Schwann cells. Glycolaldehyde causes apoptosis in Schwann cells. Nrf2 activated by glycolaldehyde plays a protective role in the cytotoxicity.
Schwann cell injury is caused by diabetic neuropathy. The apoptosis of Schwann cells plays a pivotal role in diabetic nerve dysfunction. Glycolaldehyde is a precursor of advanced glycation end products that contribute to the pathogenesis of diabetic neuropathy. In this study, we examined whether glycolaldehyde induces endoplasmic reticulum (ER) stress and apoptosis in rat Schwann cells. Schwann cells treated with 500 μM glycolaldehyde showed morphological changes characteristic of apoptosis. Glycolaldehyde activated apoptotic signals, such as caspase-3 and caspase-8. Furthermore, it induced ER stress response involving RNA-dependent protein kinase-like ER kinase (PERK), inositol-requiring ER-to-nucleus signal kinase 1α (IRE1α), and eukaryotic initiation factor 2α (eIF2α). In addition, glycolaldehyde activated CCAAT/enhancer-binding homologous protein (CHOP), an ER stress response factor crucial to executing apoptosis. Knockdown of nuclear factor E2-related factor 2 (Nrf2), which is involved in the promotion of cell survival following ER stress, enhanced glycolaldehyde-induced cytotoxicity, indicating that Nrf2 plays a protective role in the cytotoxicity caused by glycolaldehyde. Taken together, these findings indicate that glycolaldehyde is capable of inducing apoptosis and ER stress in Schwann cells. The ER stress induced by glycolaldehyde may trigger the glycolaldehyde-induced apoptosis in Schwann cells. This study demonstrated for the first time that glycolaldehyde induced ER stress.

Abstract
Aging is the progressive accumulation of damage to an organism over time leading to disease and death. Aging research has been very intensive in the last years aiming at characterizing the pathophysiology of aging and finding possibilities to fight age-related diseases. Various theories of aging have been proposed. In the last years advanced glycation end products (AGEs) have received particular attention in this context. AGEs are formed in high amounts in diabetes but also in the physiological organism during aging. They have been etiologically implicated in numerous diabetes- and age-related diseases. Strategies inhibiting AGE accumulation and signaling seem to possess a therapeutic potential in these pathologies. However, still little is known on the precise role of AGEs during skin aging. In this review the existing literature on AGEs and skin aging will be reviewed. In addition, existing and potential anti-AGE strategies that may be beneficial on skin aging will be discussed.

Abstract
Metabolic pathways may seem arbitrary and unnecessarily complex. In many cases, a chemist might devise a simpler route for the biochemical transformation, so why has nature chosen such complex solutions? In this review, we distill lessons from a century of metabolic research and introduce new observations suggesting that the intricate structure of metabolic pathways can be explained by a small set of biochemical principles. Using glycolysis as an example, we demonstrate how three key biochemical constraints--thermodynamic favorability, availability of enzymatic mechanisms and the physicochemical properties of pathway intermediates--eliminate otherwise plausible metabolic strategies. Considering these constraints, glycolysis contains no unnecessary steps and represents one of the very few pathway structures that meet cellular demands. The analysis presented here can be applied to metabolic engineering efforts for the rational design of pathways that produce a desired product while satisfying biochemical constraints.

Abstract
Liver diseases are often associated with hyperglycemia, inflammation, and oxidative stress. These conditions, commonly associated with diabetes mellitus and obesity, facilitate the formation of advanced glycation end products (AGEs). These products are known to impair protein function and promote inflammation. Accumulation of AGEs such as N(ε)-(carboxymethyl)lysine (CML) is related to chronic liver diseases and their severity. Although several reports suggest a crucial role of AGEs in liver failure, there is little investigation on the direct effects of reducing sugars, precursors of AGEs, and on the onset and progression of liver failure. In this work, we investigate the effects of intravenously administrated glycolaldehyde (GA), a short-chain aldehyde, on oxidative parameters in the liver of Wistar rats. Animals received a single injection of GA (10, 50, or 100 mg/kg) and were sacrificed after 6, 12, or 24 hours. Levels of protein carbonyl, lipid peroxidation, and reduced thiol were quantified. The activities of catalase, superoxide dismutase, and glyoxalase I were also assessed. The amount of CML was quantified with specific antibody. There was an increase in oxidative stress markers in the liver of GA-treated rats. Glycolaldehyde induced a decrease in the activities of all enzymes assayed. Also, all tested doses led to an increase in CML content. Our data suggest that GA might play an important role in liver diseases through the impairment of antioxidant defenses and generation of AGEs.

Abstract
Cardiovascular complications account for 80% of the mortality related to diabetes mellitus. Hyperglycemia is believed to be the major culprit of angiopathy and cardiomyopathy. High glucose levels and oxidative stress cause elevation of Advanced Glycation End-products that are known to contribute to diabetic complications and correlate with many diseases. However, there are few reports describing the effects of glycating agents other than glucose. Here, we aimed to evaluate the effects of glycolaldehyde (GA) on oxidative stress parameters in the heart of Wistar rats. Male Wistar rats received a single injection of GA (10, 50 or 100 mg/Kg) and were sacrificed 6, 12 or 24 h after injection. As indexes of oxidative stress, we quantified protein carbonylation, lipid peroxidation and total reduced thiols. The activities of superoxide dismutase, catalase and glyoxalase I were assayed. Also, the content of N (ɛ)-(carboxymethyl)lysine (CML) was quantified. Glycolaldehyde induced an imbalance in the redox status, with increased protein carbonylation and lipoperoxidation. Catalase and glyoxalase I had a decrease in their activities. Despite the oxidative stress, we observed no increase in CML content. These results suggest that short-chain aldehydes such as GA might have a significant role in the development of diabetic cardiomyopathy.

Abstract
Renal failure is a key pathological issue in diabetic patients. Increased levels of advanced glycation end-products (AGEs) have been associated to diabetic complications, including diabetic nephropathy. Models of AGE-treated animals have been applied to evaluate the effect of such molecules on oxidative parameters involved in the pathogenesis and evolution of diabetes disease. However, little is known about the effect of glycating agents other than glucose. Here we investigate the effect of intravenously administrated glycolaldehyde (GA) on oxidative stress parameters of the kidney. Male Wistar rats received a single injection of GA in different doses (10, 50 or 100mg/kg) and were sacrificed after 6, 12 or 24h. Activities of antioxidant enzymes catalase, superoxide dismutase and glyoxalase I were assayed. Damage to proteins and lipids were also assayed. The content of N(epsilon)-(carboxymethyl)lysine (CML) was quantified. Glycolaldehyde induced a decrease in the activity of all enzymes studied. Lipoperoxidation and protein carbonylation raised, accompanied by a decrease in sulfhydryl groups. Despite the oxidative stress generated by GA, no change was found in the content of CML, suggesting that accumulation of AGEs in the kidney might occur at later steps in the development of diabetic nephropathy.

Abstract
Glyoxal is an endogenous compound, the levels of which are increased in various pathologies associated with hyperglycaemia and other related disorders. It has been reported to inactivate critical cellular enzymes by promoting their cross-linking and perpetuates advanced glycation end-product (AGE) formation. In this study, we used superoxide dismutase (SOD) as a model to investigate the ability of specific anti-enzyme antibodies and monomer Fab fragments to protect against glyoxal-induced deactivation and aggregate formation. We found that glyoxal deactivated SOD, in a concentration and time-dependent fashion. The enzymatic activity was monitored spectrophotometrically and it was found that enzyme lost approximately 95% of its original activity, when exposed to 10 mM glyoxal for 120 h. SDS-polyacrylamide gel electrophoresis demonstrated the formation of high molecular weight aggregates in SOD samples exposed to glyoxal. Surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) showed increase in relative molecular mass (M(r)), upon exposure to glyoxal. Specific anti-enzyme antibodies and monomer Fab fragments markedly inhibited SOD deactivation caused by glyoxal and decreased the extent of cross-linking or formation of aggregates. This protection by the antibodies or Fab fragments was specific since, other non-specific antibodies were not able to protect SOD. Previously, antibodies have been used to prevent aggregation of beta-amyloid peptides in Alzheimer and prion-protein disease.

[PMID: 16545681 DOI: 10.1016/j.freeradbiomed.2005.10.065] [Citation(s) in RCA: 17] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2005] [Revised: 10/06/2005] [Accepted: 10/31/2005] [Indexed: 10/25/2022]
Abstract
Glycolaldehyde (GA) is formed by oxidative degradation of glucose, from glycated proteins, lipid peroxidation, and oxidation of amino acids, and by human neutrophils during phagocytosis. The exact purpose of GA production by phagocytes is unclear, but it is tempting to speculate that it is part of the defense against invading bacteria and tumor cells. We have already reported that GA induces apoptosis in breast cancer cells. Because the GA carbonyl group cannot be blocked by cyclization, it is prone to enolization followed by air oxidation with concomitant production of glyoxal and superoxide. Since both these products can induce oxidative stress, in this work we focused on the ability of GA to cause oxidative cell damage. MCF7 human breast cancer cells were incubated with different GA concentrations and O2*- production, lipid peroxidation, and carbonylated protein were assessed. GA was cytotoxic at 20 microM, inhibiting cell proliferation, and at 100 microM, induced p53 expression and caused apoptosis. These events were accompanied by increases of O2*- production, lipid peroxidation, and accumulation of protein carbonyl. It thus appears that alpha-hydroxy aldehydes can induce oxidative stress. Prevention of oxidative stress, however, did not abolish the effects of GA on cell growth and viability, which appeared to be a direct consequence of glyoxal toxicity.

Abstract
Aldehydes are organic compounds that are widespread in nature. They can be formed endogenously by lipid peroxidation (LPO), carbohydrate or metabolism ascorbate autoxidation, amine oxidases, cytochrome P-450s, or myeloperoxidase-catalyzed metabolic activation. This review compares the reactivity of many aldehydes towards biomolecules particularly macromolecules. Furthermore, it includes not only aldehydes of environmental or occupational concerns but also dietary aldehydes and aldehydes formed endogenously by intermediary metabolism. Drugs that are aldehydes or form reactive aldehyde metabolites that cause side-effect toxicity are also included. The effects of these aldehydes on biological function, their contribution to human diseases, and the role of nucleic acid and protein carbonylation/oxidation in mutagenicity and cytotoxicity mechanisms, respectively, as well as carbonyl signal transduction and gene expression, are reviewed. Aldehyde metabolic activation and detoxication by metabolizing enzymes are also reviewed, as well as the toxicological and anticancer therapeutic effects of metabolizing enzyme inhibitors. The human health risks from clinical and animal research studies are reviewed, including aldehydes as haptens in allergenic hypersensitivity diseases, respiratory allergies, and idiosyncratic drug toxicity; the potential carcinogenic risks of the carbonyl body burden; and the toxic effects of aldehydes in liver disease, embryo toxicity/teratogenicity, diabetes/hypertension, sclerosing peritonitis, cerebral ischemia/neurodegenerative diseases, and other aging-associated diseases.

Abstract
The effect of Maillard reaction on red blood cells (RBC) deformability was investigated. Exposure of RBC to carbonyl compounds (dl-glyceraldehyde, glyoxal, glycolaldehyde, 3-deoxyglucosone, and d-glucose) leading to Maillard reaction caused a marked decrease in RBC deformability even at 1mM level. The decrease rate depended on the kind of carbonyl compounds, in which both dl-glyceraldehyde and glyoxal significantly decreased the RBC deformability (p<0.05). In addition, the decrease rate also differed among volunteers tested, indicating that the sensitivity against carbonyl compounds varies among them. In order to elucidate the mechanism of the decrease in RBC deformability, RBC was exposed to carbonyl compounds in the presence of aminoguanidine which is the inhibitor of AGE formation in Maillard reactions. Aminoguanidine inhibited the decrease in RBC deformability by dl-glyceraldehyde and glyoxal. When Hb which has a high reactivity with carbonyl compounds was incubated with those carbonyl compounds, dl-glyceraldehyde and glyoxal showed the high reactivity with Hb compared with other carbonyl compounds. These results indicate that Maillard reaction between RBC proteins and carbonyl compounds leads to the decrease in RBC deformability. On the other hand, O(2)(-) generated by carbonyl compounds involved in lowering the deformability only to a negligible level.

Abstract
A novel flow-injection assay (FIA) system with a double line for catalase activity was constructed in which an oxidase is immobilized and the substrate is continuously pumped to reduce the dissolved oxygen and to generate a given level of hydrogen peroxide. The catalase in a sample decomposed the hydrogen peroxide, and thus the increase in dissolved oxygen dependent on the activity was amperometrically monitored using a Clark-type oxygen electrode. Among the examined several oxidases, uricase was most suitable for the continuous formation of hydrogen peroxide from a consideration of the stability and the conversion efficiency. Under the optimum conditions, a linear calibration curve was obtained in the range from 21 to 210 units/mg and the reproducibility (CV) was better than 2% by 35 successive determinations of 210 units/ml catalase preparation. The sampling frequency was about 15 samples/h. The present FIA system was applicable to monitor the inactivation of catalase by glycation.

Abstract
A novel highly water-soluble tetrazolium salt, WST-1 (4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate sodium salt), can be reduced to water-soluble formazan with a superoxide anion. Here, the WST-1 assay was applied to detect the superoxide anion generated during the Maillard reaction. A sample solution containing carbonyl compounds such as glyceraldehyde and glycolaldehyde (5 mM) and Na-acetyl-L-lysine (10 mM) was incubated for 2 days at 37 degrees C. The detection of a superoxide anion generated in the sample was performed by the WST-1 assay, and the result was compared with the cytochrome c assay. The reduction of WST-1 was almost perfectly (86-96%) inhibited by the addition of the superoxide dismutase (SOD). On the contrary, the reduction of cytochrome c was slightly (20-25%) inhibited by the addition of SOD. A similar result was observed for the addition of 4,5-dihydroxy-1,3-benzene disulfonic acid (Tiron). These results mean that the specificity of WST-1 to the superoxide anion was superior to that of cytochrome c. It was also possible to continuously monitor superoxide anion generation during the Maillard reaction by the coexistence of WST-1 in the reaction solution.

Abstract
Glycolaldehyde, an intermediate of the Maillard reaction, and fructose, which is mainly derived from the polyol pathway, rapidly inactivate human Cu,Zn-superoxide dismutase (SOD) at the physiological concentration. We employed this inactivation with these carbonyl compounds as a model glycation reaction to investigate whether carnosine and its related compounds could protect the enzyme from inactivation. Of eight derivatives examined, histidine, Gly-His, carnosine and Ala-His inhibited the inactivation of the enzyme by fructose (p<0.001), and Gly-His, Ala-His, anserine, carnosine, and homocarnosine exhibited a marked protective effect against the inactivation by glycolaldehyde (p<0.001). The carnosine-related compounds that showed this highly protective effect against the inactivation by glycolaldehyde had high reactivity with glycolaldehyde and high scavenging activity toward the hydroxyl radical as common properties. On the other hand, the carnosine-related compounds that had a protective effect against the inactivation by fructose showed significant hydroxyl radical-scavenging ability. These results indicate that carnosine and such related compounds as Gly-His and Ala-His are effective anti-glycating agents for human Cu,Zn-SOD and that the effectiveness is based not only on high reactivity with carbonyl compounds but also on hydroxyl radical scavenging activity.

Abstract
BACKGROUND Non-enzymatic glycation occurring in normal human skin plays an important part in ageing. OBJECTIVES To visualize and quantify, in human subjects, the extent of glycation during human dermal intrinsic and actinic ageing, and to develop a reliable reproducible in vitro model for evaluating the efficacy of potential inhibitors of glycation. METHODS By immunohistochemistry using a monoclonal antibody recognizing carboxymethyl lysine, an advanced glycation end-product (AGE) (first objective), and by incubating dead de-epidermized dermis (DED) with glucose to simulate ageing-induced glycation in a human dermal equivalent model (second objective). RESULTS We found that glycation of the dermis generally arises after 35 years, then increases rapidly with intrinsic ageing. We also noticed an enhancement of glycation by solar irradiation that occurred via glycation of the elastic fibre network or solar elastosis tissue. In the model, production of AGEs appeared in a time-dependent way, mimicking glycation observed in vivo during chronological ageing. Irradiation of DED before incubation with glucose strongly enhanced induction of AGEs, corresponding to the effect of solar irradiation on AGEs observed in vivo. CONCLUSIONS These results confirm a marked increase of AGEs during intrinsic ageing in normal human skin and also suggest that glycation is enhanced in photoaged skin.
