Statin drugs markedly reduce low-density lipoprotein cholesterol and consequently the incidence of cardiac events. In approximately 5-10% of adults, these drugs are associated with a range of muscle side effects such as muscle pain, cramping and weakness. Reduction in mitochondrial coenzyme Q10 (CoQ10), or ubiquinone, has been proposed as a mechanism for these statin-associated muscle symptoms (SAMS), and thus various formulations of CoQ10 are marketed and consumed for the prevention and treatment of SAMS. However, data supporting the efficacy of CoQ10 are equivocal, with some studies showing that CoQ10 supplementation reduces the incidence and severity of SAMS and others finding no beneficial effects of supplementation...

BACKGROUND: The impact of nutritional status and diet composition on mitochondrial oxidative phosphorylation (OXPHOS) in fish remains largely unknown. To identify biomarkers of interest in nutritional studies, herein we obtained a deep-coverage transcriptome by 454 pyrosequencing of liver and skeletal muscle cDNA normalised libraries from long-term starved gilthead sea bream (Sparus aurata) and fish fed different diets. RESULTS: After clean-up of high-throughput deep sequencing reads, 699,991 and 555,031 high-quality reads allowed de novo assembly of liver and skeletal muscle sequences, respectively (average length: 374 and 441 bp; total megabases: 262 and 245 Mbp)...

INTRODUCTION: Inflammation, as a critical factor, can cause numerous chronic diseases by creating various proinflammatory cytokines. Coenzyme Q10 (CoQ10) can potentially exert an anti-inflammatory agent; in turn, this agent can reduce the systemic inflammatory response. The aims of this study are to conduct a comprehensive systematic review and a meta-analysis for the determination of the CoQ10 efficacy on the changes in serum interleukin-6 (IL-6) and the tumour necrosis factor-α (TNF-α) levels in unhealthy subjects...

OBJECTIVES: Coenzyme Q10 (CoQ10, ubiquinone) stands among the safest supplements in the elderly to protect against cardiovascular disorders. Noteworthy, CoQ10 deficiency is common in many surviving stroke patients as they are mostly prescribed statins for the secondary prevention of stroke incidence lifelong. Accordingly, the current study aims to experimentally examine whether CoQ10 supplementation in animals receiving atorvastatin may affect acute stroke-induced injury. METHODS: Adult rats underwent transient middle cerebral artery occlusion after atorvastatin pretreatment (5 or 10 mg/ kg/day; po; 30 days) with or without CoQ10 (200 mg/kg/day)...

Parkinson's disease (PD) affects ∼1-2% of the elderly population. Development of a neuroprotective therapy that may be initiated early in the course of the disease to retard/prevent disease progression is highly desirable. This study aimed to investigate prophylactic treatment with coenzyme Q10 (CoQ10) before paraquat (PQ) exposure, a herbicide known to increase the risk for PD, to attain neuroprotection. In addition, therapeutic intervention with CoQ10 in mice already exposed to PQ (24 h) might halt ongoing neurodegeneration and behavioural deterioration...

UbiA prenyltransferase domain containing 1 (UBIAD1) is closely associated with cardiovascular diseases. However, at the cellular level, little is known about how UBIAD1 is expressed and functions in cardiomyocyte hypertrophy. The aim of the present study was to investigate the expression and role of UBIAD1 in angiotensin II (Ang II)‑induced hypertrophy in AC16 cardiomyoblast cells. The loss‑of‑function approach was used to knock down UBIAD1 in vehicle‑ and Ang II‑stimulated AC16 cells. The levels of atrial natriuretic factor (ANF) and caspase-3 were measured and compared between vehicle‑ and Ang II‑treated AC16 cells pretreated with control siRNA or siRNA against UBIAD1...

The oxygen consumption rate (OCR) in brain mitochondria is significantly lower in aged mice than in young mice, and the reduced OCR is rescued by administration of water-solubilized CoQ10 to aged mice via drinking water. However, the mechanism behind this remains unclear. Here, we show that the activity of respiratory complex IV (CIV) in brain mitochondria declined in aged mice than in young mice, with no significant change in individual respiratory complex levels and their supercomplex assembly. Reduced CIV activity in the aged mice coincided with reduced binding of optic atrophy 1 (OPA1) to CIV...

NQO1 is one of the two major quinone reductases in mammalian systems. It is highly inducible and plays multiple roles in cellular adaptation to stress. A prevalent polymorphic form of NQO1 results in an absence of NQO1 protein and activity so it is important to elucidate the specific cellular functions of NQO1. Established roles of NQO1 include its ability to prevent certain quinones from one electron redox cycling but its role in quinone detoxification is dependent on the redox stability of the hydroquinone generated by two-electron reduction...

BACKGROUND: Hypertension is one of the primary modifiable risk factors for cardiovascular disease. Adequate vitamin D (vit D) levels have been shown to reduce vascular smooth muscle contraction and to increase arterial compliance, which may be beneficial in hypertension. Further, coenzyme Q10 (COQ10) through its action to lower oxidative stress has been reported to have beneficial effects on hypertension and heart failure. This study examined the possible cardiac and renal protective effects of vit D and COQ10 both separately and in combination with an angiotensin II receptor blocker, valsartan (vals) in l-NAME hypertensive rats...
