Red mold rice extract and antioxidative effect

Donate Online Now

Amyloid beta-peptide (Abeta), a risk of Alzheimer's disease (AD), causes cell death by inflammation and oxidative stress. Red mold rice (RMR) fermented by Monascus species is regarded as cholesterol-lowering functional food in virtue of the metabolite monacolin K identified as lovastatin. In addition, RMR is also demonstrated to express antioxidation because of multiple antioxidants. Therefore, this study focuses on the synergism of RMR against Abeta neurotoxicity and compares the effect between lovastatin and RMR including monacolin K and other functional metabolites. In this study, RE 568, an ethanol extract of RMR produced by strain Monascus purpureus NTU 568, is used to protect PC12 cell against Abeta40 neurotoxicity. All tests contain the treatments with lovastatin or RE 568 including equal monacolin K levels in order to compare the effect and investigate whether other metabolites of RE 568 provide potent assistance against Abeta40 neurotoxicity. In the results, monacolin K represses Abeta40 neurotoxicity via repressing small G-protein-mediated inflammation, and other metabolites of RE 568 also exhibit potent antioxidative ability against Abeta-induced oxidative stress. Importantly, stronger effects on repressing the Abeta40-induced cell death, inflammation, and oxidative stress are performed by RE 568 than that by the equal levels of lovastatin, which results from a potent synergism made up of monacolin K, antioxidants, and anti-inflammatory agents. The present study is the first report to demonstrate the potent synergistic protection of RMR against Abeta40 neurotoxicity, which would cause RMR to be developed as potential and novel functional food for the prophylaxis of AD pathogenesis. ...http://www.medicalnewstoday.com

Omega-3 EPA triumphs over in DHA for anti-asthma potential

The omega-3 fatty acid EPA (eicosapentaenoic acid) is a more potent inflammation inhibitor than DHA (docosahexaenoic acid), says a new Anglo-American study. ...http://www.nutraingredients.com
