Scallop Extracts Inhibited LPS-Induced Inflammation by Suppressing MAPK and NF-κB Activation in RAW264.7 Macrophages

Abstract

Scallops belong to cosmopolitan family of bivalves which are found in any oceans. They are one of the most important marine fishery resources in the world. The shell, meat and pearl layer have a high utilization value and a lot of scallops are eaten as food. In this study, we established anti-inflammatory effect of Scallops water extract in lipopolysaccharide (LPS) stimulated RAW 264.7 mononuclear macrophage. Our results indicated that Scallop water extract effectively reduced the synthesis of nitric oxide (NO). In addition, Scallop water extract suppressed the reactive oxygen species (ROS) generation and the expression of IL-6 and TNF-α. Further investigation indicated that anti-inflammatory effect of Scallop water extract via suppressing downregulation of MAPK (JNK, p38 and ERK) and NF-κB signaling.
