Although various treatments have been used for weight loss to date, obese people rarely have safe and effective treatment options. Therefore, the antiobesity effects of several natural compounds are being actively investigated. This study was conducted to investigate the antiadipogenic effects of Monascus ruber-fermented Fagopyrum esculentum (red yeast buckwheat, RYB) in 3T3-L1 cells. We assessed the intracellular lipid content and adipocyte differentiation by oil red O staining and the expression of genes and proteins associated with adipocyte differentiation by reverse transcription-polymerase chain reaction and western blotting in 3T3-L1 cells...

Several risk factors such as abnormality of lipid metabolism (e.g. high levels of low-density lipoprotein cholesterol (LDL-C), elevated triglycerides and low levels of high-density lipoprotein cholesterol (HDL-C)) play a central role in the aetiology of cardiovascular disease (CVD). Nutraceutical combination together with a cholesterol-lowering action, when associated with suitable lifestyle, should furnish an alternative to pharmacotherapy in patients reporting statin-intolerance and in subjects at low cardiovascular risk...

Red yeast rice (RYR) is a dietary supplement containing monacolins obtained by fermentation of Monascus purpureus strains. Because of its structural homology with lovastatin, monacolin K inhibits HMG-CoA reductase and shows hypocholesterolemic properties comparable to synthetic statins. We studied all cases of myopathy involving RYR reported in the French national pharmacovigilance database (6 cases) and in scientific literature (9 cases). Among these cases, 9 showed elevated creatine kinase, 3 rhabdomyolysis and 2 myalgia...

Phytoene is a colorless carotenoid with increasing economic potential for skin care but with limited availability. The red yeast Xanthophyllomyces dendrorhous which has previously been used as a production platform for carotenoids was engineered as a prototype for the yield of this carotene. Phytoene was accumulated by prevention of its metabolization by desaturation in the carotenoid pathway. In a first step, the phytoene desaturase gene crtI was disrupted by insertion of a hygromycin-resistance gene. Most of the resulting transformants were heterozygote for intact and inactivated crtI...

Red yeast rice (RYR), produced by the fermentation of the Monascus purpureus mold, has been used for a long time in Asian cuisine and traditional medicine. It consists of multiple bioactive substances, including monacolins, which potentially can be used as a nutraceutical. Monacolin K, which is chemically identical to lovastatin, has been recognized as responsible for the cholesterolreducing effect of this compound. While the European Food Safety Authority maintains that the use of monacolin K from RYR preparations of at least 10 mg can produce a normal blood cholesterol level, the United States Food and Drug Administration considers monacolin K, due to its similarity with lovastatin, an unapproved drug, and therefore marketing of products that label the monacolin content is prohibited...

In this work, a new functional food combined Radix Puerariae and red yeast rice was explored. The pigment intensity, antioxidant activities and the main isoflavones of it were evaluated and compared with traditional red yeast rice and Radix Puerariae. The fermented mixture showed higher contents of isoflavones and pigment intensities than red yeast rice and Radix Puerariae. The DPPH, OH, FRAP and total antioxidant activity results of fermented mixture also showed higher antioxidant potential than those of Radix Puerariae and red yeast rice, owing to the higher pigment intensity and total phenolic contents...

Lipid production by the red yeast Rhodosporidium toruloides was explored under nutrient limitation. To determine the compositional profiles of R. toruloides cells, samples were prepared using a continuous cultivation process under nutrient limitation and analyzed via several methods, including Fourier transform infrared spectroscopy and elemental analysis. Under nitrogen limitation, as the dilution rate increased, the cellular lipid content decreased but the carbohydrate and protein contents increased. Under carbon limitation, the cellular lipid, protein, and carbohydrate contents remained relatively constant at the different dilution rates...

Dyslipidaemia is characterized by increased blood levels of total or LDL cholesterol and triglycerides, or decreased HDL cholesterol levels, and is a risk factor for cardiovascular disease. Dyslipidaemia has a high worldwide prevalence, and many patients are turning to alternatives to pharmacotherapy to manage their lipid levels. Lifestyle modification should be emphasized in all patients to reduce cardiovascular risk and can be initiated before pharmacotherapy in primary prevention of cardiovascular disease...

AIMS: Red yeast rice (RYR) is contained in dietary supplements for patients with dyslipidemia. RYR supplements contain monacolin K, which is chemically identical to lovastatin, a licensed drug with a well-known risk profile. We aim to describe the safety profile of RYR by analysing spontaneous reports of suspected adverse reactions (ARs). METHODS: Within the Italian Surveillance System of Natural Health Products, suspected ARs were collected and evaluated by a multidisciplinary group of experts to assess causality using the WHO-UMC system or the CIOMS/RUCAM score, for hepatic reactions...

BACKGROUND: Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins), are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20) is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin...

Red yeast rice is the fermentation product of the mould Monascus ruber and is traditionally used in East Asia to dye and conserve food. Its main pharmacologically active compound, monakolin K, was isolated from red yeast rice and is used as an inhibitor of cholesterol synthesis under the INN lovastatin. Lovastatin and several other statins are marketed as drugs whereas red yeast rice is offered as a food supplement. As statins can cause severe side effects, such as muscle damage and kidney failure, the dosing and information about interactions with drugs and food is essential for the use of these products...

Monascustin (1), an unusual γ-lactam, was isolated from an ethanol extract of the Monascus purpureus fermented rice. Its structure including the absolute configuration was determined by spectroscopic data analysis and confirmed by X-ray crystallography. A plausible biosynthetic pathway is discussed on the basis of amino acid derivatization. Compound 1 showed inhibitory activity against histone deacetylase 1.

Compelling evidence supports the effectiveness of the reduction of total and LDL cholesterol (TC and LDL-C) in primarily preventing cardiovascular events, within the framework of life-long prevention programs mainly consisting in lifestyle changes. Pharmacological treatment should be introduced when lifestyle changes, including use of nutraceuticals, have failed. ESC/EAS guidelines list a number of nutraceutical compounds and functional foods which have been individually studied in randomized, controlled clinical trials (RCTs)...

AIM: Evidence showed that LDL-cholesterol lowering is associated with a significant cardiovascular risk reduction. The initial therapeutic approach to hypercholesterolemia includes dietary modifications but the compliance to recommendations is often inadequate. Some dietary components with potential cholesterol-lowering activity are present in small amounts in food. Therefore, in recent years the use of "nutraceuticals" (i.e., nutrients and/or bioactive compounds with potential beneficial effects on human health) has become widespread...

BACKGROUND: Red yeast species in the Rhodotorula/Rhodosporidium genus are outstanding producers of triacylglyceride and cell biomass. Metabolic engineering is expected to further enhance the productivity and versatility of these hosts for the production of biobased chemicals and fuels. Promoters with strong activity during oil-accumulation stage are critical tools for metabolic engineering of these oleaginous yeasts. RESULTS: The upstream DNA sequences of 6 genes involved in lipid biosynthesis or accumulation in Rhodotorula toruloides were studied by luciferase reporter assay...

Background. High HDL-cholesterol (HDL-C) values are negatively correlated with cardiovascular diseases. This review analyses the effect of the supplementation with various Mediterranean diet products (artichoke, bergamot, and olive oil) and Asian diet products (red yeast rice) on the HDL-C value in dyslipidemic subjects. Methods. A systematic review has been done involving all the English written studies published from the 1st of January 1958 to the 31st of March 2016. Results. The results of this systematic review indicate that the dietary supplementation with red yeast rice, bergamot, artichoke, and virgin olive oil has promising effects on the increase of HDL-C serum levels...

Hypercholesterolemia and elevated homocysteine concentrations are associated with cardiovascular risk. Previous studies have demonstrated a cholesterol-lowering effect of red yeast rice (RYR) supplements which contained 5 to 10 mg of monacolin K. We hypothesized that the intake of a low monacolin K dose may likewise reduce low-density lipoprotein-cholesterol (LDL-C) and other plasma lipids. In secondary analyses, we tested the homocysteine lowering effect of folic acid, which was also included in the study preparation...

BACKGROUND: The yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and β-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes controlling this pathway are known, the mechanisms regulating this process remain poorly understood. Several studies have demonstrated that glucose represses carotenogenesis in X. dendrorhous, suggesting that this pathway could be regulated by catabolic repression. Catabolic repression is a highly conserved regulatory mechanism in eukaryotes and has been widely studied in Saccharomyces cerevisiae...
