NF-κB DNA binding activity. The NF-κB activity was measured at 1 hour after LPS (or saline) injection in liver tissue homogenate. Mice were treated with saline (Saline group), RIPC plus saline (RIPC/Saline group), saline plus RpostC (Saline/RpostC group), LPS (20 mg/kg, i.p.; LPS group), RIPC plus LPS (RIPC/LPS group), and LPS plus RpostC (LPS/RpostC group). i.p.: intraperitoneal. RIPC: remote ischemic preconditioning, RpostC: remote ischemic postconditioning. Data are expressed as mean ± SEM (n = 6 in each group). *P < 0.05 versus LPS group. † P < 0.05 versus Saline, RIPC/Saline, Saline/RpostC.
