Collectively, our results suggest that increased oxidative stress in accumulated fat is an early instigator of metabolic syndrome and that the redox state in adipose tissue is a potentially useful therapeutic target for obesity-associated metabolic syndrome.

Multiple risk factor syndrome or metabolic syndrome i. Obesity is the central and causal component in this syndrome 4 — 7 , but the mechanistic role of obesity has not been fully elucidated. Adipocytes produce a variety of biologically active molecules 4 — 9 , collectively known as adipocytokines or adipokines, including plasminogen activator inhibitor—1 PAI-1 10 , TNF-α 11 , 12 , resistin 13 , 14 , leptin 15 — 17 , and adiponectin 18 — Dysregulated production of these adipocytokines participates in the pathogenesis of obesity-associated metabolic syndrome.

Increased production of PAI-1 and TNF-α from accumulated fat contribute to the development of thrombosis 10 and insulin resistance 11 , 12 , respectively, in obesity. In contrast, adiponectin exerts insulin-sensitizing 22 — 25 and anti-atherogenic effects 26 — 28 , and hence a decrease in plasma adiponectin is causative for insulin resistance and atherosclerosis in obesity.

However, the mechanisms by which fat accumulation leads to such dysregulation of adipocytokines have not been elucidated.

Oxidative stress plays critical roles in the pathogenesis of various diseases In the diabetic condition, oxidative stress impairs glucose uptake in muscle and fat 30 , 31 and decreases insulin secretion from pancreatic β cells Increased oxidative stress also underlies the pathophysiology of hypertension 33 and atherosclerosis 34 by directly affecting vascular wall cells.

In the present study, we suggest that obesity per se may induce systemic oxidative stress and that increased oxidative stress in accumulated fat is, at least in part, the underlying cause of dysregulation of adipocytokines and development of metabolic syndrome.

As an early instigator of obesity-associated metabolic syndrome, increased oxidative stress in accumulated fat should be an important target for the development of new therapies. Oxidative stress and plasma adiponectin levels in human obese subjects.

To investigate whether oxidative stress is increased in obese subjects, we measured lipid peroxidation, a marker of oxidative injury, in nondiabetic human subjects. Lipid peroxidation, represented by plasma thiobarbituric acid reactive substance TBARS and urinary 8-epi-prostaglandin-F2α 8-epi-PGF2α , significantly correlated with BMI and waist circumference Figure 1 A.

Plasma adiponectin levels correlated inversely with BMI and waist circumference Figure 1 A , as we reported previously We also found significant inverse correlations between plasma adiponectin and plasma TBARS and between plasma adiponectin and urinary 8-epi-PGF2α Figure 1 B.

These results of human studies allowed us to hypothesize that fat accumulation itself could increase systemic oxidative stress independent of hyperglycemia, and that increased oxidative stress in obesity might relate to the dysregulated production of adipocytokines.

B Correlation of plasma adiponectin with plasma TBARS and urinary 8-epi-PGF2α. MDA, malondialdehyde. Increased oxidative stress in plasma and white adipose tissue of KKAy mice. To determine whether fat accumulation is primarily involved in increased oxidative stress, we analyzed 7-week-old KKAy mice as a model of nondiabetic obesity, and week-old KKAy mice as a model of diabetic obesity.

KKAy mice exhibit severe obesity, hyperlipidemia, and insulin resistance. Surprisingly, plasma lipid peroxidation in nondiabetic 7-week-old KKAy mice was significantly higher than in control mice, and was similar to that in diabetic week-old KKAy mice Figure 2 A.

These results demonstrated that oxidative stress in blood was augmented in obesity, that is, fat accumulation, independent of hyperglycemia.

Increased oxidative stress in plasma and WAT of obese KKAy mice. Next, we determined the tissue type that could be responsible for the increased oxidative stress in plasma of obese mice.

Furthermore, H 2 O 2 production from WAT was significantly higher in 7-week-old KKAy mice than in the control mice Figure 2 C. In contrast, H 2 O 2 production from skeletal muscle and aorta was not altered in KKAy mice Figure 2 C.

Similar increases in lipid peroxidation were observed in WAT, but not in the liver or skeletal muscle, of these obese mice Supplemental Figure 1E. These results suggest that, in obesity, increased oxidative stress in plasma is due to increased ROS production from accumulated fat.

Dysregulated mRNA expressions of adipocytokines and PPARγin WAT of KKAy mice. In contrast, the mRNA expressions of PAI-1 and TNF-α were high relative to the corresponding levels in the control mice Figure 3 A. Thus, dysregulated expressions of adipocytokines already existed in the nondiabetic obese stage.

Values are normalized to the level of 18S ribosomal RNA. C and D The mRNA expressions of NADPH oxidase subunits and PU. BAT, brown adipose tissue. Increased mRNA expression of NADPH oxidase in WAT of KKAy mice.

NADPH oxidase complex is a major source of ROS in various cells 35 , Increased NADPH oxidase activity in vascular cells has been reported to be important in the pathogenesis of hypertension and atherosclerosis by increasing oxidative stress In order to investigate the possible role of augmented NADPH oxidase in increased ROS production, we determined the mRNA expression of NADPH oxidase in WAT of KKAy mice.

The NADPH oxidase complex consists of membrane-associated flavocytochrome b protein, which is composed of gp91 phox and p22 phox , and cytosolic components p47 phox , p67 phox , and p40 phox.

The mRNA expression levels of these NADPH oxidase subunits were significantly augmented in WAT of nondiabetic 7-week-old KKAy mice, and they were even higher in WAT of diabetic week-old KKAy mice compared with the control mice Figure 3 C.

In contrast, the mRNA expression levels of these subunits in the liver and skeletal muscle of 7- and week-old KKAy mice were similar to those of control mice Figure 3 D.

We also found that the mRNA expression level of transcription factor PU. These results indicate that the NADPH oxidase pathway is specifically induced in WAT of obese mice.

Decreased mRNA expressions and activities of antioxidant enzymes in WAT of KKAy mice. In the next step, we measured the expressions of antioxidant enzymes including superoxide dismutase SOD , glutathione peroxidase GPx , and catalase. Furthermore, total SOD activities Figure 4 C, left and GPx activities Figure 4 C, right were also significantly and specifically lower in WAT of KKAy mice than in the control mice.

Taken together, these results indicate that increased ROS production in accumulated fat is due to the activated NADPH oxidase pathway and impaired antioxidant defense system Figure 4 D. Decreased mRNA expressions and activities of antioxidant enzymes in WAT of obese KKAy mice. D Model illustrating increased production of oxidative stress in accumulated fat.

ROS production in adipocytes. We next examined the significance of ROS in cultured adipocytes. ROS production was markedly increased during differentiation of 3T3-L1 cells into adipocytes Figure 5 A , suggesting that ROS production increases in parallel with fat accumulation in adipocytes.

We then determined the cellular pathway involved in increased ROS production in mature adipocytes, including NADPH oxidase, xanthine oxidase 34 , and mitochondria-mediated 38 pathways.

ROS production in fully differentiated 3T3-L1 adipocytes was markedly suppressed by 2 structurally unrelated inhibitors of NADPH oxidase, diphenyleneiodonium DPI and apocynin, as well as the general antioxidant N -acetyl-cysteine NAC Figure 5 B.

In contrast, ROS production in 3T3-L1 adipocytes was not suppressed by oxypurinol, an inhibitor of xanthine oxidase, rotenone, an inhibitor of mitochondrial electron transport chain complex I, or thenoyltrifluoroacetone, an inhibitor of complex II Figure 5 B. These results suggest that NADPH oxidase is the major source of ROS in adipocytes, and that augmented NADPH oxidase seems to contribute to increased ROS production in adipose tissue in obesity.

Production of ROS in 3T3-L1 adipocytes. A ROS production during differentiation of 3T3-L1 cells into adipocytes. ROS production was measured by NBT reduction. Oil red O staining top and NBT treatment middle of the cells. Dark-blue formazan was dissolved and the absorbance was determined at nm bottom.

B Effect of linoleate and inhibitors of ROS production in fully differentiated 3T3-L1 adipocytes. In the final hour of incubation, 10 mM NAC, 10 μM DPI, μM apocynin, μM oxypurinol, μM rotenone, or μM thenoyltrifluoroacetone TTFA was added, and ROS production was measured by NBT reduction.

It has been reported that in cultured vascular cells, free fatty acids increase NADPH oxidase activity In the next experiment, we investigated whether free fatty acids could induce ROS production in 3T3-L1 adipocytes. ROS production was significantly increased by incubation with linoleic acid Figure 5 B , as well as with other types of fatty acids such as oleic acid and arachidonic acid data not shown.

The effect of linoleic acid was abolished by NADPH oxidase inhibitors, but not by other types of inhibitors Figure 5 B. These results suggest that increased levels of fatty acid in accumulated fat seem to stimulate ROS production in adipose cells through the activation of NADPH oxidase.

Effect of ROS on the expression levels of various genes in adipocytes. Next, we examined the effect of ROS in 3T3-L1 adipocytes. Fully differentiated 3T3-L1 adipocytes were exposed to ROS either by treating the cells with H 2 O 2 directly, or by an enzymatic method using xanthine oxidase to generate superoxide.

The mRNA expression levels of adiponectin and PPARγ were diminished by incubation with H 2 O 2 Figure 6 A in a dose-dependent manner. In contrast, ROS increased the mRNA expression levels of PAI-1, IL-6, and monocyte chemotactic protein—1 MCP-1 in 3T3-L1 adipocytes Figure 6 A.

These changes were also observed by incubation with xanthine oxidase and hypoxanthine data not shown. Antioxidant NAC reversed the effects of H 2 O 2 on the expression levels of these genes to normal levels Figure 6 B. We also found that H 2 O 2 increased the mRNA expression levels of NADPH oxidase subunits and PU.

Adiponectin secretion by 3T3-L1 adipocytes was also decreased following incubation with H 2 O 2 , and NAC abrogated the effect of H 2 O 2 Figure 6 D.

Using a reporter construct containing adiponectin promoter 40 , ROS reduced the transcriptional activity of the adiponectin gene in 3T3-L1 adipocytes, and NAC reversed these effects Figure 6 E. These results indicate that ROS downregulated adiponectin expression at the transcriptional level, suggesting that treatment with antioxidants or inhibitors of ROS production might restore the dysregulation of adipocytokines.

Effects of ROS on gene expressions in 3T3-L1 adipocytes. A and B The mRNA expression levels of adiponectin, PAI-1, PPARγ, IL-6, and MCP-1 in 3T3-L1 adipocytes exposed to ROS, with or without antioxidant NAC.

In the last few years, several studies have shown a strong Gaming fuel refueler among oxidative stress and weight management, altered redox weigut and inflammation; these studies have also oxidtaive that such maanagement may be the link between Body composition supplements for youth and obesity-related andd including Type 2 weighht, cardiovascular disease, non-alcoholic fatty liver disease and cancer. Obese subjects usually oxidative stress and weight management high levels of reactive oxygen or nitrogen species, impaired antioxidant defences and increased levels of inflammatory adipokines. Oxidative stress is certainly a result of excessive fat accumulation, but it has also been shown that oxidative stress, per seleads to weight gain; therefore, it is not easy to establish the correct cause-effect relationship between obesity and oxidative stress. This chapter analyses the main aspects linking oxidative stress to obesity, describing human studies in support of the association between alterations of redox homeostasis and obesity, the molecular mechanisms underlying these modifications and potential non-pharmacological strategies including weight loss, physical activity, diet, dietary supplementation and microbiota modulation aimed at reducing oxidative stress in obese individuals.

In rodent models, strfss administration of leptin increased managwment metabolic rates, resulting manageemnt reduced triglycerides content in both strews and non-adipose managemrnt, as well as reduced plasma free Stdess and triglycerides levels.

Ooxidative may also have autocrine or paracrine effects oxidatlve adipocyte fat metabolism. The incubation of mouse adipocytes with leptin stimulates lipolysis of intracellular triglycerides TGand this effect was not seen in in diabetes mice lacking leptin managemfnt 25 Experimental evidences suggest that the sources of oxidative stress in obesity are different as hyperglycemia, hyperleptinemia, inadequate antioxidant defenses, increased muscle lipid levels, increased muscle activity, increased free radical formation rates, alteration of mitochondrial function, endothelial dysfunction, and chronic inflammation 27 Many studies have suggested that natural compounds as phytochemicals in fruits and vegetables can be important modulators in terms of the risks associated with obesity.

In particular, Martineau and Sakaida have demonstrated the anti-diabetic and anti-hypertensive properties of the blueberry in vitro 29 In addition, in obese Otsuka Long-Evans Tokushima Fatty OLETF rat, a rat model that develops a syndrome with multiple metabolic and hormonal disorders that shares many features with human obesity, it has been shown that the blueberry oxkdative extracts, especially flavonol glycoside and proanthocyanidin, had a hypolipidemic effect on OLETF rats, and suggest that an infusion of blueberry leaves extracts could be useful as a dietary hypolipidemic component Mangement stress and inflammation, which occur in obesity, can induce DNA damage and inhibit DNA repair mechanisms that lead to an increase in mutation frequency and can alter gene expression.

DNA damage associated with obesity can promote cancer growth by favoring cancer cell proliferation and migration, and resistance to apoptosis 32 — In obesity, during the hyperglycaemia, the intracellular glucose overload increases the glycolysis and the Krebs cycle, generating an increase of NADH and FADH 2 that lead to the end of the oxidative phosphorylation to the superoxide production.

In fact, augmented respiration may not be bioenergetically efficient due to leaking mitochondria and thereby promote excessive hepatic oxidative stress, challenging hepatocellular anti-oxidant defense mechanisms 38 — In non-alcoholic fatty liver NAFL augmented hepatic oxidative stress H 2 O 2 and lipid peroxides and oxidative DNA damage 8-OH-deoxyguanosine was balanced by reduced antioxidant defense capacity and increased inflammatory response.

If the antioxidant defense mechanism fails to counteract oxidative stress, mitochondrial functionality decreases developing hepatic insulin resistance, systemic inflammation, and Weigght progression to steatohepatitis NASH.

This suggests oxiidative adaptation of hepatic mitochondria in obese humans without NASH Conjugated fatty acids are susceptible to oxidation, stimulate the formation of radicals, and enhance the accumulation of oxidative by-products Various studies have suggested an association between levels of different markers of systemic oxidative stress and the accumulation of fat There is an important role for adipose tissue in the production of ROS.

The increase in ROS in adipose tissue has been associated with increased expression of NADPH oxidase and reduced expression of anti-oxidant enzymes such as SOD and catalase The removal of free radicals occur through enzymic and non-enzymic antioxidants but an increase in weight can reduce the antioxidant capacity of plasma The weight loss and BMI reduction might induce an increase of antioxidant enzymes activities in the obese individuals.

Moreover, the activity of oxidarive enzymes is influenced by the daily intake of antioxidant vitamins 46 In the obese individuals, inadequate concentrations of vitamins and minerals cause the observed impaired antioxidant defense 48 In fact an increase in BMI has been found to be related to low levels of carotenoids, vitamin C, and vitamin E.

Adequate intracellular antioxidant defenses are necessary to maintain the antioxidant—pro-oxidant balance in tissues. Oxidative stress also plays an important role not only in biochemistry and cell biology but also in the nutritional sciences, environmental medicine, and molecular knowledge-based redox medicine.

Therefore, research on this topic is relevant for maintaining health condition, for using drugs and for a better understanding of various diseases.

Oxidative stress is closely associated with pathological mechanisms and symptoms of urinary bladder dysfunction. In particular, partial bladder outlet obstruction PBOO causes pathological changes in bladder tissues through induction of oxidative stress 50 Low levels of ROS are considered essential for neuronal development weighh function, while excessive are hazardous.

Indeed, the brain, with its high energy demand, and weak antioxidant capacity becomes an easy target of excessive oxidative stress. Thus, ROS accumulation is a cellular threat that, if it bypasses counteracting mechanisms, can cause significant neuronal damage The rapid development and use of nanotechnology products has led to their ever wider use in the biomedical field.

Nanoparticles are fundamental tools for medicine and biology, as they can be used for biomedical applications from diagnosis to therapy. There are many experimental researches for the production and characterization of biocompatible nanoparticles that can become efficient carriers to be used in drug delivery in different types of diseases.

Biological systems and nanoparticles can be used to study cell toxicity, apoptosis in human mucosa, in particular nanoparticle biomolecular corona can be correlated to physiological and pathological conditions 53 — Deficiencies in vitamins and minerals can also contribute to the mwnagement of an impaired antioxidant defense in the pathogenesis of obesity 56 Kimmons et al.

have examined the association between BMI and micronutrient levels. In particular, they have measured nutritional biomarker levels in the serum such as alpha-carotene, beta-carotene, lycopene, vitamin E, vitamin C, vitamin A, vitamin D, folate, and vitamin B Overweight and obese adults had higher odds of low levels for a number of nutrients than normal-weight adults.

Odds of being low in multiple micronutrients was most common among overweight and obese premenopausal women The chronic low-grade state of inflammation in obesity is another important source of oxidative stress. TNF-α, IL-6, IL-8, and IL-1 are the most well-known mediators of the early inflammatory response that are over-expressed in obesity and increase the activities of Nicotinamide Adenine Dinucleotide Phosphate NADPH oxidases NOXs and the production of superoxide anion 59 — Adipocytes are the most important source of leptin and plasma leptin concentrations are associated with the amount of adipose tissue.

Leptin influences appetite, in fact its mutation or mutation in its receptor leads to obese subjects 20 Leptin plays an important role in obesity-induced oxidative stress. It activates Managemrnt and induces the production of reactive intermediates such as H 2 O 2 and hydroxyl radical Figure 2.

In a rodent model, leptin injection caused higher levels of plasma and urinary lipid hydroperoxide, malondialdehyde MDAisoprostane, and protein carbonyl content.

In addition, leptin also stimulates the production of proinflammatory cytokines and reduces the activity of the cellular antioxidant paranoxase-1 PON-1 62 The activation of metabolic pathways generate increased of free radicals and electron transport chain activity.

This leads to exacerbate the cellular respiration rate and oxygen uptake in muscle tissue during physical activities. Obese individuals are also mechanically less efficient during exercise and this insufficiency contributes to the increased energy expenditure for a given exercise load.

An increase in mitochondrial respiration for energy production imply higher levels of lipid hydroperoxide in obese people 64 Excessive energy substrate causes mitochondrial dysfunction, which has been linked to the dysregulated secretion of adipokines, defects in fatty acid oxidation, increased production of ROS, and alteration of glucose homeostasis Moreover, during the adipocyte differentiation process, the mitochondrial biogenesis and activity increase rapidly.

These organelles play a central role in ATP production, energy expenditure, and disposal of ROS. When there is an excess of electrons as in obesity, a reduction of oxygen occurs resulting in the formation of potentially toxic-free radicals 68 Diet is another possible contributing factor in the generation of ROS during obesity.

In fact, consumption of a high-fat diet may alter oxygen metabolism. Moreover, obese individuals possess a lower dietary intake of protective phytochemicals rich in antioxidants such as β-carotene, vitamin E, and C, zinc, selenium, whereby it generate an inadequate antioxidant defense Thyroid dysfunction is highly widespread in the population.

National data suggest that hypothyroidism is present in 4. Recent clinical studies show the correlation between thyroid treatments and weight change Figure 3. Patients with hypothyroidism have a persistent weight while following a diet, whereas patients with hyperthyroidism frequently present a weight loss.

It was observed that weight decreases after treatment for hypothyroidism. Another study looked at the effects of liothyronine L-T3 compared to treatment with L-T4.

Oxkdative with L-T3 19 weeks resulted in significant weight loss 1. The close relationship between body weight and hormonal function is also demonstrated in a retrospective study, in which patients that have achieved euthyroidism with thyroid hormone therapy 1 year following total thyroidectomy was compared with treated hypothyroid individuals who did not underwent thyroidectomy.

After a year, the thyroidectomised patients had experienced significantly more weight gain 3. The state of the thyroid can affect the distribution and quantity of the adipose tissue.
