Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are currently the most effective medications for reducing low-density lipoprotein cholesterol concentrations. Although generally safe, they have been associated with a variety of myopathic complaints. Statins block production of farnesyl pyrophosphate, an intermediate in the synthesis of ubiquinone or coenzyme Q10 (CoQ10). Thi...
Coenzyme Q10 (CoQ10) is an essential component in the electron-transport systems of mitochondria and bacteria and is often used as a supplementary treatment for some diseases. We previously reported that the bioavailability of CoQ10 powder was less than 10%. In this study, we investigated various preparations to improve the intestinal absorption of CoQ10 with focus on the effect of emulsificati...
Aim Pancreatic stellate cells (PSCs) have a vital role in pancreatic fibrosis accompanied by pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP). Any agents which can affect the activation of PSCs could become potential candidates for treatment strategies in PDAC and CP. Our aim was to explore the effect of Coenzyme Q10 (CoQ10) in the process of PSCs activation. Methods Isol...
BACKGROUND Coenzyme Q10 (CoQ10) has been suggested to be effective in the prevention of migraine, and levels can be quantified with standardized reference ranges. OBJECTIVE This study documents the prevalence of CoQ10 deficiency in migraine headache and examines the potential effectiveness of supplementation. METHODS We assessed patients attending a tertiary care center with frequent headac...
Coenzyme Q10 (CoQ10) concentration in blood cells was analyzed by HPLC and compared to plasma concentration before, during, and after CoQ10 (3 mg/kg/day) supplementation to human probands. Lymphocyte DNA 8-hydroxydeoxy-guanosine (8-OHdG), a marker of oxidative stress, was analyzed by Comet assay. Subjects supplemented with CoQ10 showed a distinct response in plasma concentrations after 14 and 2...
The processes of aging and photoaging are associated with an increase in cellular oxidation. This may be in part due to a decline in the levels of the endogenous cellular antioxidant coenzyme Q10 (ubiquinone, CoQ10). Therefore, we have investigated whether topical application of CoQ10 has the beneficial effect of preventing photoaging. We were able to demonstrate that CoQ10 penetrated into the ...
Exogenous administration of coenzyme Q10 (CoQ10) has been shown in experimental models to have a protective effect against ischemia-reperfusion injury. However, it is unclear whether follow-up plasma CoQ10 concentration is prognostic of left ventricular (LV) performance after primary balloon angioplasty in patients with acute ST segment elevation myocardial infarction (STEMI).We prospectively r...
The authors measured coenzyme Q10 (CoQ10) concentration in muscle biopsies from 135 patients with genetically undefined cerebellar ataxia. Thirteen patients with childhood-onset ataxia and cerebellar atrophy had markedly decreased levels of CoQ10. Associated symptoms included seizures, developmental delay, mental retardation, and pyramidal signs. These findings confirm the existence of an ataxi...
Introduction Coenzyme Q10 (CoQ10) is a compound found naturally in virtually every cell in the human body. Because of its ubiquitous presence in nature and its quinone structure (similar to that of vitamin K), CoQ10 is also known as ubiquinone. CoQ10 is a fat-soluble substance whose primary role is as a vital intermediate of the electron transport system in the mitochondria. Adequate amounts of...
Coenzyme Q10 (CoQ10) or ubiquinone is one of the two electron carriers in the mitochondrial respiratory chain which has an essential role in the process of oxidative phosphorylation. Defects in CoQ10 synthesis are usually associated with the impaired function of CoQ10-dependent complexes I, II and III. The recessively transmitted CoQ10 deficiency has been associated with a number of phenotypica...
