The burden of cardiovascular and metabolic diseases is increasing with every year. Although the management of these conditions has improved greatly over the years, it is still far from perfect. With all of this in mind, there is a need for new methods of prophylaxis and treatment. Coenzyme Q10 (CoQ10) is an essential compound of the human body. There is growing evidence that CoQ10 is tightly linked to cardiometabolic disorders. Its supplementation can be useful in a variety of chronic and acute disorders. This review analyses the role of CoQ10 in hypertension, ischemic heart disease, myocardial infarction, heart failure, viral myocarditis, cardiomyopathies, cardiac toxicity, dyslipidemia, obesity, type 2 diabetes mellitus, metabolic syndrome, cardiac procedures and resuscitation.

Multiple studies have determined that obesity increases asthma risk or severity. Metabolic changes of obesity, such as diabetes or insulin resistance, are associated with asthma and poorer lung function. Insulin resistance is also found to increase asthma risk independent of body mass. Conversely, asthma is associated with abnormal glucose and lipid metabolism, insulin resistance, and obesity. Here we review our current understanding of how dietary and lifestyle factors lead to changes in mitochondrial metabolism and cellular bioenergetics, inducing various components of the cardiometabolic syndrome and airway disease.

Coenzyme Q (CoQ), a lipophilic cofactor of the electron transport chain in the mitochondria, can be synthesized endogenously or provided by food. The aim of this review is to summarize the in vitro cell culture studies, the in vivo animal studies, and the human studies investigating the impact of CoQ supplementation on the occurrence of obesity and related disorders (diabetes, hypertension, lipemia, and atherosclerosis). The antioxidative properties of CoQ have been observed in different experimental models of atherosclerosis, obesity, and diabetes. The recent discovery of the anti-inflammatory effect of CoQ, mostly described in vitro, has generated increased interest in CoQ supplementation, but it needs to be confirmed in vivo in pathological situations. CoQ intervention studies in humans failed to show reproducible effects on body weight, fat mass, or glycemia, but CoQ supplementation does seem to have an antihypertensive effect. The molecular mechanism to explain this effect has only recently been discovered.

Metabolic syndrome (MetS) as a cluster of conditions including hyperlipidemia, hypertension, hyperglycemia, insulin resistance, and abdominal obesity is linked to cardiovascular diseases and type 2 diabetes. Evidence suggested that intake of curcumin and coenzyme Q10 may have therapeutic effects in the management of MetS.. We investigated the effects of curcumin and/or coenzyme Q10 supplementation on metabolic syndrome components including systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference (WC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-c) and fasting plasma glucose (FPG) as primary outcomes, and total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) and body mass index (BMI) as secondary outcomes in subjects with MetS.. In this 2 × 2 factorial, randomized, double-blinded, placebo-controlled study, 88 subjects with MetS were randomly assigned into four groups including curcumin plus placebo (CP), or coenzyme Q10 plus placebo (QP), or curcumin plus coenzyme Q10 (CQ), or double placebo (DP) for 12 weeks.. The CP group compared with the three other groups showed a significant reduction in HDL-c (P = 0.001), TG (P <  0.001), TC (P <  0.001), and LDL-c (P <  0.001). No significant differences were seen between the four groups in terms of SBP, DBP, FPG, WC, BMI and weight.. Curcumin improved dyslipidemia, but had no effect on body composition, hypertension and glycemic control. Furthermore, coenzyme Q10 as well as the combination of curcumin and coenzyme Q10 showed no therapeutic effects in subjects with MetS. The trial was registered on 09/21/2018 at the Iranian clinical trials website (IRCT20180201038585N2), URL: https://www.irct.ir/trial/32518 .

Metabolic syndrome (MetS) is a world-wide epidemic disease with an increased risk of morbidity and mortality. Treatment strategies of MetS include pharmacologic and non-pharmacologic interventions and in this respect a relevant role has been shown for nutraceutical compounds (NCs). The aim of this study was to investigate the efficacy and safety of NCs incorporated with diet and lifestyle management versus diet alone, in lowering blood pressure (BP) values and improving lipid and glucose profile, in a group of hypertensives and hyper-cholesterolemic patients with MetS.. 104 subjects with MetS (mean age 57.4 ± 8.8 years, 51% males) without history of cardio-vascular (CV) diseases were enrolled in the study. 52 subjects were treated with a once-daily oral formulation of a NCs containing red yeast rice and coenzyme Q10 added to their diet for 2 months and were compared with the 52 patients following a diet program. Differences in BP, serum total cholesterol (TC), low- and high-density-lipoprotein cholesterol (LDLC and HDLC), triglycerides (TG) and glucose values were compared by analysis of variance.. A significant reduction of BP, TC, TG, LDLC and glucose levels was observed in both treatment groups. However, a greater reduction of systolic BP (-5.2 vs. -3.0 mmHg), diastolic BP (-4.9 vs. 2.9 mmHg), total cholesterol (-17.2%), LDLC (-21.8%), TG (-16.0%) and serum glucose (-3.4%) was observed in the treatment group relative to the control (p < 0.001 for all); HDLC remained unchanged (p = N.S.). Gender difference was not found in either group (p = N.S.).. In patients with MetS, NC supplementation was safe, well tolerated and effective in improving clinic BP, lipid and glucose profile.

Limited data are available indicating the effects of coenzyme Q10 (CoQ10) supplementation on metabolic status of patients with metabolic syndrome (MetS).. The present study was conducted to determine the effects of CoQ10 administration on glucose homeostasis parameters, lipid profiles, biomarkers of inflammation and oxidative stress among patients with MetS.. This randomized, double-blind, placebo-controlled trial was performed among 60 overweight or obese and type 2 diabetes mellitus patients with coronary heart disease aged 40-85 years old. Participants were randomly allocated into two groups. Group A (n = 30) received 100 mg CoQ10 supplements and group B (n = 30) received placebo for 8 weeks. Fasting blood samples were taken at the beginning of the study and after 8-week intervention to quantify glucose homeostasis parameters, lipid profiles and biomarkers of inflammation and oxidative stress.. Compared with the placebo, CoQ10 supplementation resulted in a significant reduction in serum insulin levels (-2.1 ± 7.1 vs. +4.1 ± 7.8 µIU/mL, P = 0.002) and homeostasis model of assessment-insulin resistance (-0.7 ± 2.1 vs. +1.0 ± 2.0, P = 0.002) and homeostatic model assessment-beta cell function (-5.9 ± 22.2 vs. +15.9 ± 34.0, P = 0.005). In addition, patients who received CoQ10 supplements had a significant increase in plasma total antioxidant capacity (TAC) concentrations (+26.0 ± 105.0 vs. -162.2 ± 361.8 mmol/L, P = 0.008) compared with the placebo group. However, after adjustment for the baseline levels, age and baseline BMI, the effect on TAC levels (P = 0.08) disappeared. Additionally, compared with the placebo group, a significant positive trends in plasma glutathione (P = 0.06) and a significant reduction in malondialdehyde (P = 0.08) were seen among patients who received CoQ10 supplement. We did not observe any significant changes in fasting plasma glucose, lipid concentrations and inflammatory markers.. Overall, daily intake of 100 mg CoQ10 supplements among patients with MetS for 8 weeks had beneficial effects on serum insulin levels, HOMA-IR, HOMA-B and plasma TAC concentrations.. www.irct.ir : IRCT201502245623N35.

Psoriasis is a systemic inflammatory immune-mediated skin disease. Recently a relationship with metabolic syndrome in terms of psoriasis severity and response to therapy was observed.. We performed an open-label randomized controlled study to evaluate the role of a nutraceutical containing Q10 coenzyme, Krill-oil, lipoic acid, resveratrol, Vitis vinifera seed oil, vitamin E and selenium in addition to etanercept therapy for patients affected by psoriasis and metabolic syndrome. Forty patients were enrolled and divided into two arms, one receiving only etanercept, one other receiving also the neutraceutical. After a period of 3 months (T1) a second evaluation of the considered parameters was performed.. At T1 statistically significant differences were detected in HDL cholesterol and triglycerides values both comparing the two arms and in the nutraceutical arm.. Our results show that the dietary addiction of the nutraceutical to the etanercept therapy in patients affected by both psoriasis and metabolic syndrome could help to restore the normal lipid profile.

Our aim was to examine the effects of adjunctive coenzyme Q(10) therapy on 24-h ambulatory blood pressure (BP) in subjects with the metabolic syndrome and inadequate BP control.. In a randomized, double-blind, placebo-controlled 12-week crossover trial, coenzyme Q(10) (100 mg twice daily) or placebo was administrated to 30 subjects with the metabolic syndrome, and inadequate BP control (an average clinic BP of ≥140 systolic mm Hg or ≥130 mm Hg for patients with type 2 diabetes) while taking an unchanged, conventional antihypertensive regimen. Clinic and 24-h ambulatory BP were assessed pre- and post-treatment phases. The primary outcomes were the changes in 24-h systolic and diastolic BP during adjunctive therapy with coenzyme Q(10) vs. placebo and prespecified secondary outcomes included changes in BP loads.. Compared with placebo, treatment with coenzyme Q(10) was not associated with statistically significant reductions in systolic (P = 0.60) or diastolic 24-h ambulatory BP (P = 0.12) or heart rate (P = 0.10), although daytime diastolic BP loads, were significantly lower during coenzyme Q(10) administration with thresholds set at >90 mm Hg (P = 0.007) and ≥85 mm Hg (P = 0.03). Coenzyme Q(10) was well tolerated and was not associated with any clinically relevant changes in safety parameters.. Although it is possible that coenzyme Q(10) may improve BP control under some circumstances, any effects are likely to be smaller than reported in previous meta-analyses. Furthermore, our data suggest that coenzyme Q(10) is not currently indicated as adjunctive antihypertensive treatment for patients with the metabolic syndrome whose BP control is inadequate, despite regular antihypertensive therapy.

Between 82.8% and 92.5% of participants in any BMI group were responders by AS, and between 91.3% and 100% were responders by BBPS in the right colon. Efficacy was consistent across BMI groups, with no clear trends. Greater than 83% of participants in any BMI group found the preparation 'easy' or 'acceptable' to ingest, and the majority (>58%) rated SPMC oral solution as 'better' than a prior bowel preparation. In all BMI groups, safety data were similar to the overall cohort. Commonly reported, drug-related, treatment-emergent AEs were, by ascending BMI group, nausea (1.1%, 5.3%, 1.0%, 5.7%, and 0%) and headache (1.1%, 4.1%, 1.0%, 5.7%, and 0%).. Ready-to-drink SPMC oral solution had consistent, good quality colon cleansing, and favorable tolerability among participants of all BMI groups.. NCT03017235.. The pretreatment serum AST/ALT ratio predicts poor disease outcome and response rate in patients with advanced PDAC treated with gemcitabine/nab-paclitaxel and might represent a novel and inexpensive marker for individual risk assessment in the treatment of pancreatic cancer.. Of the 98 patients included in the study, 58 had CR (59%), 28 had PR (29%), and 12 patients had NR (12%). The percent splenic tissue embolized was significantly greater in the CR group compared to the PR group (P = 0.001). The percent volume of splenic tissue embolized was linearly correlated with the magnitude of platelet increase without a minimum threshold. At least one line of chemotherapy was successfully restarted in 97% of patients, and 41% of patients did not experience recurrence of thrombocytopenia for the duration of their survival. The major complication rate was 8%, with readmission following initial hospitalization for persistent "post-embolization syndrome" symptoms the most common.. In cancer patients with hypersplenism-related thrombocytopenia, PSAE is a safe intervention that effects a durable elevation in platelet counts across a range of malignancies and following the re-initiation of chemotherapy.. Postoperative CRP elevation was a better predictor of prognosis in patients with gastric cancer than the occurrence of intra-abdominal infectious complications.. In clinical practice, mixed-species malaria infections are often not detected by light microscopy (LM) or rapid diagnostic test, as a low number of parasites of one species may occur. Here, we report the case of an 8-year-old girl migrating with her family from Afghanistan with a two-species mixed infection with

Here, the aim was to investigate the role of circulating oxidized mitochondrial DNA (ox-mtDNA) in metabolic syndrome (MetS)-associated chronic inflammation and evaluate the effect of Mito-Quinone (MitoQ)-based antioxidant therapy on inflammation. A total of 112 MetS patients and 111 healthy control individuals (HCs) were recruited. Peripheral blood was collected, and mononuclear cells (PBMCs) were separated. In a preclinical study, MitoQ, a mitochondrial-targeted antioxidant, was administered to Sprague-Dawley (SD) rats fed a high-fat diet (HFD). In vitro, H

The dietary model of metabolic syndrome has continued to aid our understanding of its pathogenesis and possible management interventions. However, despite progress in research, therapy continues to be challenging for humans; hence, the search for newer treatment and prevention options continues.. The objective of this study was to evaluate the impact of dietary CQ10 supplementation on metabolic, oxidative, and inflammatory markers in a diet-induced mouse model of metabolic syndrome.. Mouse groups were fed a Standard Diet (SD), High-Fat High-Sugar (HFHS) diet, and SD or HFHS diet (with incorporated CQ10) at 60 and 120 mg/kg of feed. At the completion of the study (8 weeks), blood glucose levels, Superoxide Dismutase (SOD) activity, plasma insulin, leptin, adiponectin, TNF-α, IL-10, serum lipid profile, and Lipid Peroxidation (LPO) levels were assessed. The liver was either homogenised for the assessment of antioxidant status or processed for general histology.. Dietary CQ10 mitigated HFHS diet-induced weight gain, decreased glucose, insulin, and leptin levels, and increased adiponectin levels in mice. Coenzyme-Q10 improved the antioxidant status of the liver and blood in HFHS diet-fed mice while also decreasing lipid peroxidation. Lipid profile improved, level of TNF-α decreased, and IL-10 increased following CQ10 diet. A mitigation of HFHS diet-induced alteration in liver morphology was also observed with CQ10.. Dietary CQ10 supplementation mitigates HFHS diet-induced changes in mice, possibly through its anti-oxidant, anti-lipaemic, and anti-inflammatory potential.

The purpose of the study was to further reveal the mechanisms and therapeutic capabilities of the pharmacopuncture method (the introduction of drugs into the area of reflexotherapy points) in metabolic syndrome. In previously published materials on the problem, we pointed out the efficacy of the pharmacopuncture antioxidant Ubiquinone Composite (as a pilot study), similar in effect to the drug Coenzyme Composite (Heel, Germany). The present work develops this topic by further comparing the characteristics of pharmacopuncture with the presented drugs.. The study included 160 patients (103 women and 57 men) with metabolic syndrome. In addition to clinical parameters, lipid and carbohydrate metabolism, atherogenic index, catalase and superoxide dismutase activity, the level of prooxidant processes, and the presence of insulin resistance were evaluated. In the clinical phase, the patients were divided into four groups. In group 1, treatment was limited to standard medication, in other groups, pharmacopuncture was additionally performed. In the 2nd group, physiological solution (placebo) was used as an agent, in the 3rd and 4th groups - the drugs Ubiquinone compositum and Coenzyme compositum, which differ mainly in antioxidant effect.. It was found that pharmacopuncture with both drugs leads, in general, to comparable positive results, significantly superior to the effectiveness of other methods. However, certain differences were noted within these groups: in the case of using the drug Ubiquinone compositum, a predominant decrease in blood pressure and dyslipidemia is observed, and when using the drug Coenzyme compositum, a shift in insulin resistance against the background of regression of disbalance in the peroxidation system. On the one part, the presented data show about the therapeutic breadth of the effects of pharmacopuncture, and on the other part, they demonstrate the possibility of a differentiated influence.. В опубликованных ранее материалах по изучению применения метода фармакопунктуры (инъекции медикаментов в область точек рефлексотерапии) авторы настоящей статьи указывали на результативность фармакопунктуры антиоксидантом Убихинон композитум и (в качестве пилотного исследования) сходным по действию препаратом Коэнзим композитум («Хеель», Германия). Настоящая работа развивает эту тему путем дальнейшего сопоставления характеристик фармакопунктуры представленными средствами.. Раскрытие механизмов и терапевтических возможностей метода фармакопунктуры при метаболическом синдроме.. Под наблюдением находились 160 пациентов (103 женщины и 57 мужчин) с метаболическим синдромом. Помимо клинических характеристик оценивали липидный и углеводный обмен, коэффициент атерогенности, активность каталазы и супероксиддисмутазы, уровень прооксидантных процессов и наличие инсулинорезистентности. В клинической фазе пациенты были распределены на четыре группы. В 1-й группе лечение было ограничено стандартным медикаментозным пособием, в других дополнительно выполняли фармакопунктуру. При этом во 2-й группе в качестве агента использовали физиологический раствор (плацебо), в 3-й и 4-й группах — препараты Убихинон композитум и Коэнзим композитум, отличающиеся преимущественно антиоксидантным влиянием. При этом за средненормативные показатели («контроль») были приняты результаты обследования 35 условно здоровых лиц обоего пола в возрасте до 40 лет.. Установлено, что фармакопунктура обоими лекарственными средствами приводит в целом к сопоставимым положительным результатам, достоверно превосходящим эффективность других способов. Однако внутри этих групп отмечены определенные различия: в случае использования препарата Убихинон композитум наблюдается преимущественное снижение артериального давления и явлений дислипидемии, а при применении препарата Коэнзим композитум — сдвиг резистентности к инсулину на фоне регресса дисбаланса в системе перекисного окисления. Представленные данные свидетельствуют, с одной стороны, в пользу терапевтической широты эффектов фармакопунктуры, а с другой — показывают возможности дифференцированного влияния.

Maternal smoking leads to glucose and lipid metabolic disorders and hepatic damage in the offspring, potentially due to mitochondrial oxidative stress. Mitoquinone mesylate (MitoQ) is a mitochondrial targeted antioxidant with high bioavailability. This study aimed to examine the impact of maternal cigarette smoke exposure (SE) on offspring's metabolic profile and hepatic damage, and whether maternal MitoQ supplementation during gestation can affect these changes. Female Balb/c mice (eight weeks) were either exposed to air or SE for six weeks prior to mating and throughout gestation and lactation. A subset of the SE dams were supplied with MitoQ in the drinking water (500 µmol/L) during gestation and lactation. Intraperitoneal glucose tolerance test was performed in the male offspring at 12 weeks and the livers and plasma were collected at 13 weeks. Maternal SE induced glucose intolerance, hepatic steatosis, mitochondrial oxidative stress and related damage in the adult offspring. Maternal MitoQ supplementation reduced hepatic mitochondrial oxidative stress and improved markers of mitophagy and mitochondrial biogenesis. This may restore hepatic mitochondrial health and was associated with an amelioration of glucose intolerance, hepatic steatosis and pathological changes induced by maternal SE. MitoQ supplementation may potentially prevent metabolic dysfunction and hepatic pathology induced by intrauterine SE.

The prevalence of the metabolic syndrome components including abdominal obesity, dyslipidaemia and insulin resistance is increasing in both developed and developing countries. It is generally accepted that the development of these features is preceded by, or accompanied with, impaired mitochondrial function. The present study was designed to analyse the effects of a mitochondrial-targeted lipophilic ubiquinone (MitoQ) on muscle lipid profile modulation and mitochondrial function in obesogenic diet-fed rats. For this purpose, twenty-four young male Sprague-Dawley rats were divided into three groups and fed one of the following diets: (1) control, (2) high fat (HF) and (3) HF+MitoQ. After 8 weeks, mitochondrial function markers and lipid metabolism/profile modifications in skeletal muscle were measured. The HF diet was effective at inducing the major features of the metabolic syndrome--namely, obesity, hepatic enlargement and glucose intolerance. MitoQ intake prevented the increase in rat body weight, attenuated the increase in adipose tissue and liver weights and partially reversed glucose intolerance. At the muscle level, the HF diet induced moderate TAG accumulation associated with important modifications in the muscle phospholipid classes and in the fatty acid composition of total muscle lipid. These lipid modifications were accompanied with decrease in mitochondrial respiration. MitoQ intake corrected the lipid alterations and restored mitochondrial respiration. These results indicate that MitoQ protected obesogenic diet-fed rats from some features of the metabolic syndrome through its effects on muscle lipid metabolism and mitochondrial activity. These findings suggest that MitoQ is a promising candidate for future human trials in the metabolic syndrome prevention.

Metabolic syndrome has become an important health problem, which involves obesity, hyperlipidemia, insulin resistance, and high blood pressure values. The components of metabolic syndrome are all suggested as independent cardiovascular disease risk factors along with high mortality and morbidity rates accompanied by many organ and system complications.. We aimed to determine 8-isoprostane (8-IsoP) and coenzyme Q10 (CoQ10) levels in patients with metabolic syndrome and healthy individuals and demonstrate whether there was any relation between these parameters and metabolic syndrome criteria.. A total of 30 patients (10 male, 20 female) with metabolic syndrome and 20 age-matched healthy individuals (9 male, 11 female) were involved in the study. Body mass index, waist and hip circumferences, systolic and diastolic blood pressures and serum glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol, insulin, HbA1c, 8-IsoP and CoQ10 levels, and homeostasis model assessment of insulin resistance indexes of all participants were determined.. 8-IsoP levels were significantly increased in metabolic syndrome compared to healthy individuals (P = 0.003), however, there was no significant difference between groups for CoQ10 levels. 8-IsoP levels were positively correlated with waist circumference (r = 0.303, P = 0.032), diastolic blood pressure (r = 0.337, P = 0.017), systolic blood pressure (r = 0.329, P = 0.020) values and total cholesterol levels (r = 0.354, P = 0.012).. We can suggest that the levels of 8-IsoP, which is an indicator of the oxidative stress, increase in metabolic syndrome and this can be associated with high blood pressure and visceral adiposity, which are the components of metabolic syndrome.

The prevalence of metabolic syndrome (MetS) components including obesity, dyslipidemia, insulin resistance (IR), and hepatic steatosis is rapidly increasing in wealthy societies. It is accepted that inflammation/oxidative stress are involved in the initiation/evolution of the MetS features. The present work was designed to evaluate the effects of three major cellular ROS production systems on obesity, glucose tolerance, and hepatic steatosis development and on oxidative stress onset. To do so, 40 young male Sprague-Dawley rats were divided into 5 groups: 1-control group, 2-high fat (HF) group (60% energy from fat), 3-HF+ MitoQ (mitochondrial ROS scavenger), 4-HF+ Apocynin (NADPH oxidase inhibitor), 5-HF+ Allopurinol (xanthine oxidase inhibitor). After 8 weeks of these treatments, surrogate MetS, mitochondrial function, and oxidative stress markers were measured in blood and liver. As expected, rats that were fed the HF diet exhibited increased body weight, glucose intolerance, overt hepatic steatosis, and increased hepatic oxidative stress. The impacts of the studied ROS inhibitors on these aspects of the MetS were markedly different. MitoQ showed the most clinically relevant effects, attenuating body weight gain and glucose intolerance provoked by the HF diet. Both Apocynin and Allopurinol showed limited effects suggesting secondary roles of xanthine oxidase (XO) or NADPH oxidase-dependent ROS production in the onset of oxidative stress-dependent obesity, glucose intolerance, and hepatic steatosis process. Thus, MitoQ revealed the central role of mitochondrial oxidative stress in the development of MetS and suggested that mitochondria-targeted antioxidants may be worth considering as potentially helpful therapies for MetS features.

The purpose of this study was to investigate the levels of coenzyme Q10 and vitamin E and the antioxidant status in subjects with metabolic syndrome (MS). Subjects with MS (n = 72) were included according to the criteria for MS. The non-MS group (n = 105) was comprised of healthy individuals with normal blood biochemical values. The plasma coenzyme Q10, vitamin E concentrations, lipid profiles, and antioxidant enzymes levels (catalase, superoxide dismutase, and glutathione peroxidase) were measured. The subjects with MS had significantly higher concentrations of plasma coenzyme Q10 and vitamin E than those in the non-MS group, but these differences were not significant after being normalized for triglyceride level. The levels of antioxidant enzymes were significantly lower in the MS group than in the non-MS group. The subjects with the higher antioxidant enzymes activities had significant reductions in the risk of MS (P < 0.01) after being adjusted for coenzyme Q10 and vitamin E. In conclusion, the subjects with MS might be under higher oxidative stress resulting in low levels of antioxidant enzyme activities. A higher level of antioxidant enzymes activities was significantly associated with a reduction in the risk of MS independent of the levels of coenzyme Q10 and vitamin E.

We have previously found abrogated ischemia-induced coronary collateral growth in Zucker obese fatty (ZOF) rats compared with Zucker lean (ZLN) rats. Because ZOF rats have structural abnormalities in their mitochondria suggesting dysfunction and also show increased production of O(2), we hypothesized that mitochondrial dysfunction caused by oxidative stress impairs coronary collateral growth in ZOF.. Increased levels of reactive oxygen species were observed in aortic endothelium and smooth muscle cells in ZOF rats compared with ZLN rats. Reactive oxygen species levels were decreased by the mitochondria-targeted antioxidants MitoQuinone (MQ) and MitoTempol (MT) as assessed by MitoSox Red and dihydroethidine staining. Lipid peroxides (a marker of oxidized lipids) were increased in ZOF by ≈47% compared with ZLN rats. The elevation in oxidative stress was accompanied by increased antioxidant enzymes, except glutathione peroxidase-1, and by increased uncoupling protein-2 in ZOF versus ZLN rats. In addition, elevated respiration rates were also observed in the obese compared with lean rats. Administration of MQ significantly normalized the metabolic profiles and reduced lipid peroxides in ZOF rats to the same level observed in lean rats. The protective effect of MQ also suppressed the induction of uncoupling protein-2 in the obese rats. Resolution of mitochondrial oxidative stress by MQ or MT restored coronary collateral growth to the same magnitude observed in ZLN rats in response to repetitive ischemia.. We conclude that mitochondrial oxidative stress and dysfunction play a key role in disrupting coronary collateral growth in obesity and the metabolic syndrome, and elimination of the mitochondrial oxidative stress with MQ or MT rescues collateral growth.

A number of recent studies suggest that mitochondrial oxidative damage may be associated with atherosclerosis and the metabolic syndrome. However, much of the evidence linking mitochondrial oxidative damage and excess reactive oxygen species (ROS) with these pathologies is circumstantial. Consequently the importance of mitochondrial ROS in the etiology of these disorders is unclear. Furthermore, the potential of decreasing mitochondrial ROS as a therapy for these indications is not known. We assessed the impact of decreasing mitochondrial oxidative damage and ROS with the mitochondria-targeted antioxidant MitoQ in models of atherosclerosis and the metabolic syndrome (fat-fed ApoE(-/-) mice and ATM(+/-)/ApoE(-/-) mice, which are also haploinsufficient for the protein kinase, ataxia telangiectasia mutated (ATM). MitoQ administered orally for 14weeks prevented the increased adiposity, hypercholesterolemia, and hypertriglyceridemia associated with the metabolic syndrome. MitoQ also corrected hyperglycemia and hepatic steatosis, induced changes in multiple metabolically relevant lipid species, and decreased DNA oxidative damage (8-oxo-G) in multiple organs. Although MitoQ did not affect overall atherosclerotic plaque area in fat-fed ATM(+/+)/ApoE(-/-) and ATM(+/-)/ApoE(-/-) mice, MitoQ reduced the macrophage content and cell proliferation within plaques and 8-oxo-G. MitoQ also significantly reduced mtDNA oxidative damage in the liver. Our data suggest that MitoQ inhibits the development of multiple features of the metabolic syndrome in these mice by affecting redox signaling pathways that depend on mitochondrial ROS such as hydrogen peroxide. These findings strengthen the growing view that elevated mitochondrial ROS contributes to the etiology of the metabolic syndrome and suggest a potential therapeutic role for mitochondria-targeted antioxidants.

Metabolic syndrome (MetS) is a group of cardiovascular risk factors, including visceral obesity, glucose intolerance, hypertension, and dyslipidemia. Increased oxidative and nitrative stress and inflammation and decreased endothelial function occur in an animal model of metabolic syndrome, SHR/NDmcr-cp (SHR/cp) rats. The present study investigated the effects of coenzyme Q10 (CoQ10), one of the important antioxidants, on the abnormal oxidative condition and characteristic components of metabolic syndrome in SHR/cp rats by maintaining them on a diet supplemented with 0.07% - 0.7% CoQ10 for 26 weeks. We determined serum levels of oxidatively modified low-density lipoprotein (Ox-LDL) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) as oxidative stress markers, 3-nitrotyrosine as a nitrative stress marker, 3-chlorotyrosine as a marker of myeloperoxidase (MPO)-catalyzed oxidation and high-sensitivity C-reactive protein (hsCRP) as an inflammatory marker. The administration of CoQ10 significantly attenuated the increase of oxidative and nitrative stress markers and inflammatory markers in a dose-dependent manner. CoQ10 prevented the elevated serum insulin levels, although it did not affect the elevated glucose level and dyslipidemia. CoQ10 also reduced elevated blood pressure, but did not affect body weight gain. In addition, CoQ10 improved endothelial dysfunction in the mesenteric arteries. These findings suggest that the antioxidant properties of CoQ10 can be effective for ameliorating cardiovascular risk in MetS.

Adipose tissues are differently involved in lipid metabolism and obesity according to their type and location. Increasing reports stress on the impact of redox metabolism on obesity and metabolic syndrome. The aim of this work is to investigate the site-specific redox metabolism in three different adipose tissues and its changes occurring in obesity. We analysed enzymatic and non-enzymatic parameters, and focused on the reduced/oxidized glutathione and coenzyme Q couples. In lean compared with obese non-diabetic Zucker rats, interscapular brown fat seems well protected against oxidative stress and epididymal adipose tissue shows a more reduced glutathione redox state, associated with a higher susceptibility to lipophilic oxidative stress than inguinal adipose tissue. Epididymal adipose tissue redox metabolism significantly differs from inguinal one by its limited redox metabolism adaptation. Our results demonstrate site-specific managements of reactive oxygen species metabolism in obese Zucker rats. These results are not consistent with the classic deciphering of inflammatory situation and produce a new conception of the redox parameters implication in the development of the metabolic syndrome.

The purpose of this study was to determine whether coenzyme Q10 (CoQ) concentrations and redox status are associated with components of the metabolic syndrome.. This is a cross-sectional survey of 223 adults (28-78 years), who were drawn from the ongoing Princeton Follow-up Study in greater Cincinnati. Individuals were assessed for measures of fatness, blood pressure, glucose, lipid profiles, C-reactive protein (CRP), reduced CoQ (ubiquinol), oxidized CoQ (ubiquinone), total CoQ and CoQ redox ratio (ubiquinol/ubiquinone).. After adjusting for age, sex and race, we found that total CoQ, ubiquinol and CRP levels are significantly increased in metabolic syndrome. Comparison of minimal risk and high-risk metabolic syndrome groups indicates an increased CoQ redox ratio in the high risk group (p<0.05). Step-wise logistic regression analysis, using age, sex, race, (ln)CRP, total cholesterol, LDL, ubiquinol, ubiquinone and total CoQ as predictors, shows that only age (p=0.001), total CoQ adjusted for plasma lipids (p<0.0001) and (ln)CRP (p<0.005) were significant predictors of metabolic syndrome.. The presence of metabolic syndrome components are associated with increased plasma total CoQ and ubiquinol concentrations after adjusting for age, sex and race. An increase in CoQ redox ratio may indicate a gender-specific adaptive response to oxidative stress in females, but not males.
