Sivelestat attenuates intestinal inflammation in HFHC-fed Apo E-/- mice and NE-treated intestinal epithelial cells. (A–E) Male Apo E-/- mice were fed with HFHC diet for 4 weeks and then treated with sivelestat (Siv, 50 mg/kg per day, intraperitoneal injection) or Veh for 8 weeks. ELISA analysis of intestinal protein levels of TNF-α (A), IL-1β (B), and MCP-1 (C). Immunoblot analysis of protein expressions of phosphorylated (phos-) IκB and IκB (D) and quantitative analysis of the relative density of phos-IκB/IκB (E). Data are shown as mean ± SEM. n = 6 mice/group, and **p < 0.01 and ***p < 0.001.
