Popis: Rutin is the major polyphenol found in buckwheat and can downregulate inflammatory responses in macrophages. However, the underlying mechanism is unclear. Overproduction of nitric oxide (NO) by inducible nitric synthase (iNOS) is closely correlated with inflammation and the pathology of a variety of diseases. It has been reported that rutin inhibited various pro-inflammatory mediators, including cytokine signaling in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells, and suppressed the production of NO and the expression of cyclooxygenase-2 (COX-2) and iNOS protein in LPS-stimulated macrophages. These results suggest that rutin exerts anti-inflammatory effects by suppressing the expression of COX-2 and iNOS in RAW 264.7 macrophage cells. Therefore, rutin can be considered as a functional food for the prevention of various diseases.
