Red yeast rice, a commercially available food supplement known to reduce serum cholesterol, has been repeatedly advocated as alternative therapy for hypercholesterolemic patients that refuse statins, cannot tolerate statin therapy's side effects, or request a "naturopathic" medicine. Red yeast rice contains a fungus (Monascus purpureus), which was utilized in the original production of lovastatin (Mevacor TM), the first marketed pharmaceutical statin, and is chemically identical to such product. Their identical properties account for the similarity in therapeutic and side effects of red yeast rice and lovastatin...

Most eukaryotic oleaginous species are yeasts and among them the basidiomycete red yeast, Rhodotorula (Rhodosporidium) toruloides (Pucciniomycotina) is known to produce high quantities of lipids when grown in nitrogen-limiting media, and has potential for biodiesel production. The genome of the CGMCC 2.1609 strain of this oleaginous red yeast was sequenced using a hybrid of Roche 454 and Illumina technology generating 13 × coverage. The de novo assembly was carried out using MIRA and scaffolded using MAQ and BAMBUS...

The inflammation and oxidative stress of bone marrow-derived proangiogenic cells (PACs), also named endothelial progenitor cells, triggered by hyperglycemia contributes significantly to vascular dysfunction. There is supporting evidence that the consumption of red yeast rice (RYR; Monascus purpureus-fermented rice) reduces the vascular complications of diabetes; however, the underlying mechanism remains unclear. This study aimed to elucidate the effects of RYR extract in PACs, focusing particularly on the role of a potent antioxidative enzyme, heme oxygenase-1 (HO-1)...

BACKGROUND: About 10-15% patients who take statins experience skeletal muscle problems. Red yeast rice has a good safety profile could provide a compromise therapeutic strategy. Therefore, the aim of this study was to evaluate the effects of red yeast rice, when compared to simvastatin, on the muscle fatigue symptom and the serum lipid level in dyslipidemic patients with low to moderate cardiovascular risk. METHODS: A total of 60 dyslipidemic patients with low to moderate cardiovascular risk were recruited and randomly assigned to receive either simvastatin (n = 33) or red yeast rice (n = 27) for 4 weeks...

Red yeast rice product (RYP) has been used as a food supplement because of its lipid lowering, and in food additives as a natural colorant. Lovastatin of RYP is a hypolipidemic commercial drug. To enhance the beneficial effects of RYP, we performed a bioconversion with Bacillus subtilis. This B. subtilis-fermentation process of RYP increased the ratio of the active open-hydroxyl acid form and the prodrug lactone form of lovastatin, which is a potent cholesterol synthesis inhibitor. 3(2H)-benzofuranone was newly produced in the fermented red yeast rice product (FRYP) as analyzed by GC-MS...

In addition to the cholesterol-lowering activity of red yeast rice (RYR), its anticancer activities have been frequently reported. However, the mechanism of action of the anticancer activity of RYR is not yet fully understood. The objective of the current study was to elucidate anticancer compositions and anticancer mechanism of actions of RYR. The isolated compounds from RYR were subjected to anti-proliferation assay, apoptosis assay via flow cytometry, and telomerase inhibitory assay via telomeric repeat amplification protocol-PCR (TRAP-PCR) assay, and Western blotting assay in an in vitro cell culture system...

The red yeast Rhodosporidium toruloides is a known lipid producer capable of accumulating large amounts of triacylglycerols and carotenoids. However, it remains challenging to study its carotenoid production profiles due to limited biochemical information and inefficient genetic tools. Here we used an Agrobacterium tumefaciens-mediated transformation (ATMT) to change its carotenoid production and profiles. We constructed R. toruloides NP11 mutant libraries with ATMT, selected 3 mutants with different colors, characterized their carotenoid products by high pressure liquid chromatography-mass spectrometry (HPLC-MS) analysis, and assured differences among those strains in terms of carotenoid production and its composition profiles...

Matrix effect-free UHPLC-MS/MS method was developed and validated for the determination of cholesterol-lowering lovastatin in food samples represented by Pu-erh tea, oyster mushroom, and red yeast rice. The resulting method was fully validated in terms of intra-day and inter-day precision, accuracy, linearity, range, LOD, LOQ, and matrix effects. The matrix effect phenomenon evaluated by comparison of slopes of calibration curves was completely eliminated by solid-phase extraction based on the technique of molecularly imprinted polymers (MIPs)...

Hypercholesterolemia is one of the major risk factors for the development of cardiovascular disease. Atherosclerosis resulting from hypercholesterolemia causes many serious cardiovascular diseases. Statins are generally accepted as a treatment of choice for lowering low-density lipoprotein (LDL) cholesterol, which reduces coronary heart disease morbidity and mortality. Since statin use can be associated with muscle problems and other adverse symptoms, non-adherence and discontinuation of statin therapy often leads to inadequate control of plasma cholesterol levels and increased cardiovascular risk...

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...
