英文摘要

We have previously shown that homocysteine (Hcy) can induce monocyte chemoattractant protein-1 (MCP-1) secretion via reactive oxygen species (ROS) in human monocytes. Here, we show that Hcy upregulates expression of an important antioxidative protein, thioredoxin (Trx), via NADPH oxidase in human monocytes in vitro. The increase of Trx expression and activity inhibited Hcy-induced ROS production and MCP-1 secretion. Of note, 2-week hyperhomocysteinemia (HHcy) ApoE(-/-) mice showed accelerated lesion formation and parallel lower Trx expression in macrophages than ApoE(-/-) mice, suggesting that HHcy-induced sustained oxidative stress in vivo might account for impaired Trx and hence increased ROS production and MCP-1 secretion from macrophages, and subsequently accelerated atherogenesis.
