Coenzyme Q10 (CoQ10) is a powerful antioxidant substance synthesized in the body. The current study aimed to determine whether CoQ10 suppresses inflammation and inhibits p-STAT3 expression in an experimental colitis mouse model. The mice were orally fed with CoQ10 once a day for 13 days. Histological analysis of the colons was performed by immunohistochemistry. Expression of IL-17, FOXP3, p53, AMPK, and mTOR and activation of p-STAT3 and p-STAT5 in lymph node and spleen tissues were detected by confocal microscopy of stained tissue sections...

Coenzyme Q10 (CoQ10) plays a critical role in mitochondrial oxidative phosphorylation by serving as an electron carrier in the respiratory electron transport chain. CoQ10 also functions as a lipid-soluble antioxidant by protecting lipids, proteins and DNA damaged by oxidative stress. CoQ10 deficiency has been associated with a number of human diseases including mitochondrial diseases, neurodegenerative disorders, cardiovascular diseases, diabetes, cancer, and with the ageing process. In many of these conditions CoQ10 supplementation therapy has been effective in slowing or reversing pathological changes...

BACKGROUND: A couple may be considered to have fertility problems if they have been trying to conceive for over a year with no success. This may affect up to a quarter of all couples planning a child. It is estimated that for 40% to 50% of couples, subfertility may result from factors affecting women. Antioxidants are thought to reduce the oxidative stress brought on by these conditions. Currently, limited evidence suggests that antioxidants improve fertility, and trials have explored this area with varied results...

The degeneration of the rostral ventrolateral medulla (RVLM) catecholaminergic neurons was responsible for some cardiovascular symptoms in Parkinson's disease (PD). Our previous study had observed the impairment of these neurons in the early stage of PD in the rotenone-induced PD rat model, but the related mechanisms remain unclear. Rotenone is a mitochondrial inhibitor, influencing the neuronal electrophysiological activity through activation of K-ATP channels that potentially participate in cell death processes...

REVIEW
Fabien Pierrel
Coenzyme Q is a lipid that participates to important physiological functions. Coenzyme Q is synthesized in multiple steps from the precursor 4-hydroxybenzoic acid. Mutations in enzymes that participate to coenzyme Q biosynthesis result in primary coenzyme Q deficiency, a type of mitochondrial disease. Coenzyme Q10 supplementation of patients is the classical treatment but it shows limited efficacy in some cases. The molecular understanding of the coenzyme Q biosynthetic pathway allowed the design of experiments to bypass deficient biosynthetic steps with analogs of 4-hydroxybenzoic acid...

The role of dietary fat unsaturation and the supplementation of coenzyme Q have been evaluated in relation to bone health. Male Wistar rats were maintained for 6 or 24 months on two diets varying in the fat source, namely virgin olive oil, rich in monounsaturated fatty acids, or sunflower oil, rich in n-6 polyunsaturated fatty acids. Both dietary fats were supplemented or not with coenzyme Q10 (CoQ10). Bone mineral density (BMD) was evaluated in the femur. Serum levels of osteocalcin, osteopontin, receptor activator of nuclear factor κB ligand (RANKL), osteoprotegerin (OPG), adrenocorticotropin (ACTH) and parathyroid hormone (PTH), as well as urinary F₂-isoprostanes were measured...

Diabetic nephropathy (DN) is one of the most common and lethal microvascular complications of diabetes. This study aimed to explore whether coenzymeQ10 (CoQ10) as an antioxidant combined with ultrasound-targeted microbubble destruction (UTMD) could reverse the progress of early diabetic nephropathy (DN). CoQ10 has great potential to treat early DN. However, the clinical application of CoQ10 has been limited because of its low aqueous solubility and non-specific distribution. Therefore, CoQ10-loaded liposomes (CoQ10-lip) were prepared and combined with ultrasound microbubbles for the early theranostics of DN...

PURPOSE: Increasing evidence suggests that Mediterranean Diet (MD) is correlated with reduced risk of breast cancer (BC) and cancer mortality, since it modifies patients' serum antioxidant capacity, body composition and biochemical parameters. The aim of the study was to investigate whether a dietary intervention based on MD has a beneficial effect on these factors. METHODS: In this intervention study, seventy female BC survivors were randomly assigned to (1) the intervention group (personalized dietary intervention based on MD) and (2) the control group (received the updated American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer Prevention and ad libitum diet)...

Coenzyme Q10 (CoQ10) is an essential cofactor of the mitochondrial oxidative phosphorylation (OXPHOS) system and its deficiency has important implications for several inherited metabolic disorders of childhood. The biosynthesis of CoQ10 is a complicated process, which involves at least 12 different enzymes. One of the metabolic intermediates that are formed during CoQ10 biosynthesis is the molecule 6-demethoxyubiquinone (6-DMQ). This CoQ precursor is processed at the level of COQ7 and COQ9. We selected this metabolite as a marker substance for metabolic analysis of cell lines with inherited genetic defects (COQ2, COQ4, COQ7 and COQ9) or siRNA knockdown in CoQ biosynthesis enzymes using ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS)...

Coenzyme Q10 (CoQ10) is a mitochondrial-targeted antioxidant with known neuroprotective activity. Its ocular effects when co-solubilised with α-tocopherol polyethylene glycol succinate (TPGS) were evaluated. In vitro studies confirmed that CoQ10 was significantly protective in different retinal ganglion cell (RGC) models. In vivo studies in Adult Dark Agouti (DA) rats with unilateral surgically-induced ocular hypertension (OHT) treated with either CoQ10/TPGS micelles or TPGS vehicle twice daily for three weeks were performed, following which retinal cell health was assessed in vivo using DARC (Detection of Apoptotic Retinal Cells) and post-mortem with Brn3a histological assessment on whole retinal mounts...

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 phenotypically and genetically heterogeneous groups of disorders manifesting at variable age of onset. The infantile, multisystemic presentation is usually caused by mutations in genes directly involved in CoQ10 biosynthesis...
