Abstract
Oxidative stress resulted from reactive oxygen or nitrogen species in biological
systems has a significant role in the diagnosis/progression of several human
diseases. Human diseases associated with oxidative stress include Alzheimer's
disease, chronic lung disease, chronic renal failure, cancer, diabetes, and
fibrosis. In oxidative stress conditions, carbonylation process can be described
as one of the most common modifications in biomolecules that takes place in the
presence of carbonyl (C = O) groups which are introduced into molecules by
direct metal-catalyzed oxidation of certain amino acids or indirectly by
reaction with the oxidation of lipids and sugars. At a molecular cellular level,
carbonylation can cause some defective biological consequences or chemical
transformations in cells. During this process, specifically, carbonylated
proteins can be accumulated in cells and trigger to develop some diseases in
human body. The role of the accumulation of carbonylated proteins in the
progression of several diseases has also been reported in the literature, such
as neurodegenerative diseases, diabetes, obesity, aging, and cancer. Early
detection of carbonylation process is, therefore, very critical to monitor these
diseases at an early stage. Finding a suitable biomarker or probe is very
challenging due to the need for multiple criteria: high fluorescence efficiency,
stability, toxicity, and permeability. If they are designed with a good
strategy, these probes are highly effective in cell biology applications and
they can be used as good diagnostic tools for monitoring oxidative
stress-induced carbonylation in relevant diseases. This review highlights the
design and use of recent fluorescent probes for visualization of carbonylation
in cellular systems and the relationship between oxidative stress and carbonyl
species for causing long-term disease complications.

Protein Pept Lett 2021; 28:282-289. [PMID: 32957872 DOI: 10.2174/0929866527666200921165312] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 07/29/2020] [Accepted: 08/04/2020] [Indexed: 01/04/2023]
Abstract
BACKGROUND Myoglobin is an oxygen binding protein and its dysfunction has been associated with the pathology of several human disorders. This study was undertaken to investigation the role of hydrogen peroxide (H2O2) in the formation of met-myoglobin and the protective potential of four different reductants such as uric acid, folic acid, glutathione and ascorbic acid were also tested against met-myoglobin formation. METHODS Human myoglobin was treated with H2O2 in-vitro in order to prepare met-myoglobin. The generation of met-myoglobin was confirmed by UV-visible spectroscopy and its stability was analysed by the treatment of human myoglobin with H2O2 at varying pH or time. High performance liquid chromatography (HPLC) was used to determine the oxidatively modified heme products in met-myoglobin. Spectroscopic analysis was used to identify the protective potential of uric acid, folic acid, glutathione and ascorbic acid against the formation of met-myoglobin. RESULTS The novel data of this study showed that H2O2 induced extensive damage of myoglobin but the treatment with uric acid, folic acid, glutathione or ascorbic acid provides protection of myoglobin against H2O2 induced oxidative damaged. The study apparently proved the protective potential of all these compounds against the toxicity produced by H2O2. CONCLUSION This is the first study that shows uric acid, folic acid, glutathione and ascorbic acid provide protection against the generation of toxic met-myoglobin and might be used therapeutically to modify the blood conditions in order to prevent the progression of human disorders associated with myoglobin dysfunction.

Abstract
Generation of reactive oxygen species and related oxidants is an inevitable consequence of life. Proteins are major targets for oxidation reactions, because of their rapid reaction rates with oxidants and their high abundance in cells, extracellular tissues, and body fluids. Additionally, oxidative stress is able to degrade lipids and carbohydrates to highly reactive intermediates, which eventually attack proteins at various functional sites. Consequently, a wide variety of distinct posttranslational protein modifications is formed by protein oxidation, glycoxidation, and lipoxidation. Reversible modifications are relevant in physiological processes and constitute signaling mechanisms ("redox signaling"), while non-reversible modifications may contribute to pathological situations and several diseases. A rising number of publications provide evidence for their involvement in the onset and progression of diseases as well as aging processes. Certain protein oxidation products are chemically stable and formed in large quantity, which makes them promising candidates to become biomarkers of oxidative damage. Moreover, progress in the development of detection and quantification methods facilitates analysis time and effort and contributes to their future applicability in clinical routine. The present review outlines the most important classes and selected examples of oxidative protein modifications, elucidates the chemistry beyond their formation and discusses available methods for detection and analysis. Furthermore, the relevance and potential of protein modifications as biomarkers in the context of disease and aging is summarized.

Abstract
Tobacco-specific nitrosamines (TSNAs) are carcinogens that accumulate in tobacco leaves during curing, storage, and processing, and their amounts in processed tobacco vary dependent on several intrinsic and extrinsic factors. Here, we assessed the hypothesis that there is a link between reactive oxygen species levels in leaves and TSNA formation during curing. First, we show that burley varieties KT 204LC and NCBH 129LC accumulate TSNAs to different levels but not as a result of a variety-specific abundance of TSNA precursors. Next, we measured the levels of reactive oxygen species, and we show that the variety that accumulates more TSNAs, NCBH 129LC, had significantly higher levels of hydrogen peroxide than KT 204LC. The NCBH 129LC also has more oxidatively damaged and glutathionylated proteins. Finally, we analyzed the antioxidant levels in KT 204LC and NCBH 129LC and their tolerance to oxidative stress. NCBH 129LC contained more of the essential antioxidant glutathione and was more tolerant to the oxidative stress-generating compound paraquat. Collectively, our data suggest that there is indeed a link between foliar oxidative stress parameters and the extent to which TSNAs accumulate in cured tobacco leaves.

Abstract
The reactions of protein oxidation play a significant role in many biological processes, especially in diseases development. Therefore, it is important to understand, how the protein molecule behaves in the presence of oxidants. In the present work, photo-oxidation of phytohormone-binding plant protein (VrPhBP) was investigated using light and 3-carboxybenzophenone (3CB) as a sensitizer (one electron oxidant). The protein interacts with the sensitizer in the ground state forming a weak binding complex leading to the presence of bound and free 3CB in solution. The early events and transient species (such as radicals and radical ions) formed during irradiation were characterised by transient spectroscopy showing the formation of the sulphur radical cation Met>S●+ (stabilized by (S∴N)+)and the tyrosyl radical TyrO● on VrPhBP. Thus the 3CB excited triplet state was quenched by the Met and Tyr residues and mostly by Met (based on the deconvoluted transient absorption spectra).The presence of a Tyr side chain in the vicinity of a Met residue results in intramolecular electron transfer from Tyr to the Met>S●+ radical cation, leading to regeneration of the thioether side chain and formation of TyrO●. The presence of other side chains close to Met, such as Arg or Lys can induce the stabilization of Met>S●+ via the formation of two-centered three-electron bonded species (S∴N)+. The transient species were additionally confirmed by stable product analysis. Based on SDS-PAGE, chromatography and mass spectrometry, the formation of methionine sulphoxide and Met-3CB adduct was identified together with di-Tyr cross links. On the basis of the experimental results the overall mechanism of VrPhBP photo-oxidation, from its early events to the formation of stable products, is described. In addition, a good correlation between the mechanisms of photooxidation of model compounds such as Met derivatives and peptides and those for real biological systems is emphasized.

Abstract
The liver failure means inability to perform its normal synthetic, biotransformation and excretory functions. The disturbance of metabolic processes leads to the development of "metabolic endogenous intoxication" resulting in oxidative stress. Oxidative stress initiates the processes of oxidation of amino acid residues of blood plasma proteins causing the changes in their structure and functions. The effect of administration of highly activated porous carbonic enterosorbents on oxidative stress manifestations and molecular conformation of serum albumin in blood of experimental animals with acute liver failure induced by carbon tetrachloride (CCl4) needs to be investigated. Two forms of activated carbonic enterosorbents such as AC1 (primary beads with the range of diameters of 125-250 μm) and AC2 (secondary granules prepared from micronized AC1 having the mean particle size of ~1 μm) derived from phenol-formaldehyde resin were used in rat model with CCl4 intoxication. The total level of reactive oxygen species (ROS) in blood plasma, the activity of catalase (CAT) in blood hemolysates; the content of reduced glutathione (GSH) in liver homogenates, and the level of oxidative modification of proteins (OMP) such as aldehyde-dinitrophenylhydrazone (A-DNPH) and ketone-dinitrophenylhydrazone (K-DNPH) derivatives in blood plasma and liver homogenates were determined. In addition, the level of pro/antioxidant ratio in blood hemolysates and the content of lipid peroxidation product - malondialdehyde (MDA), in blood plasma and liver were determined. Melting thermograms of blood plasma proteins (BPP) and molecular conformation changes of serum albumin were analyzed by biophysical methods (differential scanning microcalorimetry and spectrofluorimetry). The extent of CCl4-induced oxidative damage in blood and liver of experimental animals was shown to be less expressed for AC1 in comparison with AC2 enterosorbent. However, AC2 used in the form of secondary granules positively influenced some biophysical properties of albumin molecule (temperature of melting, shape of melting endotherm and intrinsic fluorescence) after rats exposure to CCl4. In general, administration of both AC1 and AC2 led to the reduction of oxidative stress manifestations and partial restoration of native molecular conformation of serum albumin. These observations are promising in terms of achieving recovery of detoxification potential of organism after severe liver injury.

Abstract
Temperature is an abiotic factor that affects various biological and physiological processes in fish. Temperature stress is known to increase the production of reactive oxygen species (ROS) that subsequently cause oxidative stress. Fish is known to evolve a system of antioxidant enzymes to reduce ROS toxicology. Glutathione peroxidase (GPx) family consists of key enzymes that protect fish from oxidative stress. In this study, full-length GPx1 cDNA (GenBank accession no. KY984468) of Tor tambroides was cloned and characterized by rapid amplification of cDNA ends (RACE). The 899-base-pair (bp) GPx1 cDNA includes a 576-bp open reading frame encoding for 191 amino acids, plus 28 bp of 5'-untranslated region (UTR) and 295 bp of 3'-UTR. Homology analysis revealed that GPx1 of T tambroides (Tor-GPx1) shared high similarity with GPx1 sequences of other fish species. The phylogenetic construction based on the amino acid sequence showed that Tor-GPx1 formed a clade with GPx1 sequences of various fish species. Real-time polymerase chain reaction (PCR) was performed to assess the levels of GPx1 gene expression in the liver and muscle of T tambroides under thermal stress. The results indicated that GPx1 gene expression was down-regulated under decreased temperature. However, there was no significant difference between GPx1 gene expression in fish exposed to high temperature and control. Our study provides the first data regarding GPx gene expression in T tambroides under thermal stress.

Abstract
Oxidative stress arising during diabetes may lead to cataract formation. Thus, in order to prevent oxidative stress development, antioxidants could be considered helpful agents. Naringenin, a flavonoid with a well-documented antioxidative activity, can be found in many plant-derived products, especially citrus fruits. The aim of the study was to examine the effect of naringenin on oxidative stress markers in the lenses of type 1 diabetic rats. The study was conducted on 3-month-old male Wistar rats with streptozotocin-induced type 1 diabetes. The rats were treated orally with naringenin at the doses of 50 and 100 mg/kg for 4 weeks. In the lenses obtained from the animals, enzymatic and non-enzymatic parameters connected with oxidative stress were measured. The enzymatic parameters included superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase activity. For non-enzymatic parameters, the total thiol groups, reduced and oxidized glutathione, protein carbonyl groups, advanced oxidation protein products, malondialdehyde and vitamin C level were assayed. Oral administration of naringenin counteracted most of the unfavorable changes induced by diabetes, including reduction of elevated antioxidative enzymes activity and amelioration of oxidative damage in proteins and lipids. Naringenin administered orally reduces oxidative stress markers in the lenses of type 1 diabetic rats.

Abstract
OBJECTIVES Induced dilated cardiomyopathy is the main limitation of the anti-cancer drug doxorubicin, which causes oxidative stress and cardiomyocyte death. As ozone therapy can activate the antioxidant systems, this study aimed to investigate the therapeutic efficacy of ozone-oxidative preconditioning against doxorubicin-induced cardiotoxicity. METHODS The study was carried out from September 2013 to January 2014. Sprague-Dawley rats were randomly distributed in the following treatment groups: Group 1 were treated with 2 mg/kg intraperitoneal (i.p.) of doxorubicin twice a week for 50 days; Group 2 were treated with 0.3 mg of ozone/oxygen mixture at 50 μg/mL of ozone per 6 mL of oxygen by rectal insufflation and then treated with doxorubicin; Group 3 were treated as Group 2 but only with the oxygen, and Group 4 were treated with oxygen first, and then with sodium chloride i.p. as the control group. RESULTS The results showed that ozone therapy preserved left ventricle morphology which was accompanied by a reduction of serum pro-brain natriuretic peptide levels. The cardioprotective effects of ozone-oxidative preconditioning were associated with a significant increase (P <0.05) of antioxidant enzymes activities and a reduction of lipid and protein oxidation (P <0.05). CONCLUSION Ozone-oxidative preconditioning prevents doxorubicin-induced dilated cardiomyopathy through an increase of antioxidant enzymes and a reduction of oxidised macromolecules. This establishes the background for future studies to determine if ozone therapy can be used as a complementary treatment for attenuating doxorubicin-induced cardiotoxicity in cancer patients.

Abstract
The heart is highly sensitive to the aging process. In the elderly, the heart tends to become hypertrophic and fibrotic. Stiffness increases with ensuing systolic and diastolic dysfunction. Aging also affects the cardiac response to stress. At the molecular level, the aging process is associated with accumulation of damaged proteins and organelles, partially due to defects in protein quality control systems. The accumulation of dysfunctional and abnormal mitochondria is an important pathophysiological feature of the aging process, which is associated with excessive production of reactive oxygen species. Mitochondrial fusion and fission and mitochondrial autophagy are crucial mechanisms for maintaining mitochondrial function and preserving energy production. In particular, mitochondrial fission allows for selective segregation of damaged mitochondria, which are afterward eliminated by autophagy. Unfortunately, recent evidence indicates that mitochondrial dynamics and autophagy are progressively impaired over time, contributing to the aging process. This suggests that restoration of these mechanisms could delay organ senescence and prevent age-associated cardiac diseases. Here, we discuss the current understanding of the close relationship between mitochondrial dynamics, mitophagy, oxidative stress, and aging, with a particular focus on the heart.

Abstract
Cobalt-based materials are widely used for coronary stents, as well as bone and joint implants. However, their use is associated with high corrosion incidence. Titanium alloys, by contrast, are more biocompatible owing to the formation of a relatively inactive titanium oxide (TiO2) layer on their surface. This study was aimed at improving Co28Cr6Mo alloy cytocompatibility via sol-gel TiO2 coating to reduce metal corrosion and metal ion release. Owing to their role in inflammation and tissue remodelling around an implant, endothelial cells present a suitable in vitro model for testing the biological response to metallic materials. Primary human endothelial cells seeded on Co28Cr6Mo showed a stress phenotype with numerous F-actin fibres absent on TiO2-coated material. To investigate this effect at the gene expression level, cDNA microarray analysis of in total 1301 genes was performed. Compared with control cells, 247 genes were expressed differentially in the cells grown on Co28Cr6Mo, among them genes involved in proliferation, oxidative stress response and inflammation. TiO2 coating reduced the effects of Co28Cr6Mo on gene expression in endothelial cells, with only 34 genes being differentially expressed. Quantitative real-time polymerase chain reaction and protein analysis confirmed microarray data for selected genes. The effect of TiO2 coating can be, in part, attributed to the reduced release of Co(2+), because addition of CoCl2 resulted in similar cellular responses. TiO2 coating of cobalt-based materials, therefore, could be used in the production of cobalt-based devices for cardiovascular and skeletal applications to reduce the adverse effects of metal corrosion products and to improve the response of endothelial and other cell types.

Eur J Pharmacol 2012; 691:156-62.

Abstract
Coronary artery disease (CAD) is the most common cause of sudden death, and death of people over 20 years of age. Because ozone therapy can activate the antioxidant system and improve blood circulation and oxygen delivery to tissue, the aim of this study was to investigate the therapeutic efficacy of ozone in patients with CAD, treated with antithrombotic therapy, Aspirin and policosanol. A randomized controlled clinical trial was performed with 53 patients divided into two groups: one (n=27) treated with antithrombotic therapy and other (n=26) treated with antithrombotic therapy plus rectal insufflation of O(3). A parallel group (n=50) age and gender matched was used as reference for the experimental variables. The efficacy of the treatments was evaluated by comparing hemostatic indexes and biochemical markers of oxidative stress in both groups after 20 day of treatment. Ozone treatment significantly (P<0.001) improved prothrombin time when compared to the antithrombotic therapy only group, without modifying bleeding time. Combination antithrombotic therapy+O(3) improved the antioxidant status of patients reducing biomarkers of protein and lipid oxidation, enhancing total antioxidant status and modulating the level of superoxide dismutase and catalase with a 57% and 32% reduction in superoxide dismutase and catalase activities respectively, moving the redox environment to a status of low production of O(2)(•-) with an increase in H(2)O(2) detoxification. No side effects were observed. These results show that medical ozone treatment could be a complementary therapy in the treatment of CAD and its complications.

Abstract
Background Neuromyelitis optica is a central nervous system demyelinating and inflammatory syndrome. The objective of this study is to identify cytokines related to the cellular immune response as well as blood brain barrier integrity and oxidative stress. Methods We performed a molecular characterization of cellular immune response and oxidative stress in serum from relapsing-NMO (R-NMO) patients and established the correlations between the clinical measurements and molecular parameters using the Bayesian approach. Serum samples from 11 patients with R-NMO diagnosed according to Wingerchuk criteria and matched in terms of age, gender and ethnicity with the healthy controls were analyzed. The levels of TNF-α, IFN-γ, IL-10, MMP-9, TIMP-1 and oxidative stress markers: malondialdehyde, advanced oxidation protein products, peroxidation potential, superoxide dismutase, catalase, and total hydroperoxides were measured. Results We found almost undetectable levels of TNF-α, a decreased production of IL-10 and a significant up-regulation of every oxidative stress biomarker studied. The insufficient production of TNF-α and IL-10 in R-NMO patients, which are two important players of T cell mediated immunoregulation, suggest an effector – regulator imbalance. The overproduction of oxygen reactive species as a consequence of the chronic inflammatory milieu is reflected on the excess of oxidative damage mediators detected. Furthermore, Multidimensional Scaling and a Bayesian linear regression model revealed a significant linear dependence between Expanded Disability Status Scale Kurtzke and TIMP-1; pointing to a possible predictive or prognostic value of this clinical-molecular relationship. Conclusion These results suggest that there is a breakdown in immunoregulatory mechanisms and noteworthy pro-oxidant environment contributing to NMO pathogenesis.

Abstract
4-hydroxynonenal (HNE) is a highly toxic product of lipid peroxidation (LPO). Its role in the inhibition of cytochrome c oxidase activity and oxidative modifications of mitochondrial lipids and proteins were investigated. The exposure of mitochondria isolated from rat heart to HNE resulted in a time- and concentration-dependent inhibition of cytochrome c oxidase activity with an IC50 value of 8.3 +/- 1.0 microM. Immunoprecipitation-Western blot analysis showed the formation of HNE adducts with cytochrome c oxidase subunit I. The loss of cytochrome c oxidase activity was also accompanied by reduced thiol group content and increased HNE-lysine fluorescence. Furthermore, there was a marked increase in conjugated diene formation indicating LPO induction by HNE. Fluorescence measurements revealed the formation of bityrosines and increased surface hydrophobicity of HNE-treated mitochondrial membranes. Superoxide dismutase + catalase and the HO* radical scavenger mannitol partially prevented inhibition of cytochrome c oxidase activity and formation of bityrosines. These findings suggest that HNE induces formation of reactive oxygen species and its damaging effect on mitochondria involves both formation of HNE-protein adducts and oxidation of membrane lipids and proteins by free radicals.

Abstract
BACKGROUND Reactive oxygen species (ROS) play an important role in several pathogenic processes, damaging various structural and functional cellular components. The endothelium is at major risk of radical-induced lesions and this damage is most manifest in microcirculation. It has been recently observed that ROS are implicated in the pathology of the inner ear and the peripheral and central pathways. In a previous study we detected high serum values of ROS in subjects with idiopathic tinnitus. The purpose of the present study was to evaluate the validity of antioxidant treatment in tinnitus sufferers with high ROS values. METHODS The study considered 31 consecutive patients with unilateral idiopathic tinnitus. The mean pure tone audiometric threshold (PTA), tinnitus loudness, subjective disturbance level [visual analogue scale (VAS) determination], and the indirect ROS dosage 48 h before and after medical treatment were evaluated. Patients underwent an 18-week oral treatment with a mix of phospholipids and vitamins (glycerophosphorylcholine, glycerophosphorylethanolamine, beta-carotene, vitamin C, vitamin E). RESULTS ROS levels were significantly reduced following antioxidant treatment (malonaldehyde: 2.10 vs. 1.98 mumol/dL, p = 0.003; 4-hydroxynonenal: 2.36 vs. 2.16 mumol/dL, p = 0.002) In addition, great improvement was observed in the reduction of tinnitus (VAS and tinnitus loudness evaluations). No significant changes in audiometric threshold occurred. CONCLUSIONS Oral antioxidant therapy in patients with idiopathic tinnitus seems to reduce the subjective discomfort and tinnitus intensity and may be considered as an additional treatment modality.
