Abstract

Lycopene, found in tomatoes and tomato products, has antioxidant, anticancer, and anti-inflammatory effects. High-mobility-group box 1 (HMGB1) mediates the pro-inflammatory responses in several inflammatory diseases. In this study, the potential roles of lycopene in the HMGB1-mediated pro-inflammatory gene expressions in the primary human-umbilical-vein endothelial cells (HUVECs) were investigated. The data showed that HMGB1 upregulated the expressions of monocyte chemotactic protein 1 (MCP-1), interleukin-6 (IL-6), secretory phospholipase A2 (sPLA2)-IIA, and prostaglandin E2 (PGE2). Lycopene pre-incubation for 6 h decreased the HMGB1-mediated induction of MCP-1, IL-6, sPLA2-IIA, and PGE2. Further study revealed that the inhibitory effects of lycopene on the HMGB-1 induced expression of pro-inflammatory genes were mediated by the inhibition of two important inflammatory cytokines: tumor necrosis factor (TNF)-${\alpha}$ and nuclear factor (NF)-${\kappa}B$. These results suggest that HMGB1 upregulated the expression of pro-inflammatory genes and lycopene inhibited HMGB-1-induced pro-inflammatory genes by inhibiting TNF-${\alpha}$ and NF-${\kappa}B$. This finding will serve as an important evidence in the development of a new medicine for the treatment of inflammatory diseases.

본 연구에서는 HMGB1 의해 증가되는 각종 염증관련물질에 대해 라이코펜이 가지는 저해 역할을 규명하고 하였다. 라이코펜은 HMGB1에 의해 증가되는 MCP-1, IL-8, sPLA2-IIA, PGE2의 발현을 NF-${\kappa}B$ 그리고 TNF-${\alpha}$의 활성를 저해함으로써 감소시켰다. 특히, 1 mM에서 그 효능이 통계적으로 유효하였다. 결론적으로 HMGB1에 의해서 발생하는 각종 혈관염증질환에서 라이코펜은 증가하는 각종 염증관련물질을 저해하였고, 결국 라이코펜이 패혈증을 포함하는 염증질환을 효과적으로 치료할 수 있는 방법에 있어 많은 방향성을 제시할 것으로 기대한다.
