Pretreatment with Nepetin dose-dependently inhibited IL-6, IL-8 and MCP-1 secretion with IC50 values of 4.43, 3.42 and 4.17 μM, respectively[1]. Nepetin (2.5-10 μM; 25 hours; ARPE-19 cells) treatment suppresses IL-1β-induced cytokine (IL-6, IL-8 and MCP-1) expression at mRNA level in ARPE-19 cells[1]. Nepetin (2.5-10 μM; 1.5 hours; ARPE-19 cells) treatment dose-dependently inhibits phosphorylation of IKKα/β and IκBα, and nuclear translocation of p65. Nepetin decreases the level of phosphorylated ERK1/2, JNK and p38 MAPK in activated ARPE-19 cells[1]. RT-PCR[1] Cell Line: ARPE-19 cells Concentration: 2.5 μM, 5 μM, 10 μM Incubation Time: 25 hours Result: Suppressed the mRNA expression of IL-6, IL-8 and MCP-1 in ARPE-19 cells. Western Blot Analysis[1] Cell Line: ARPE-19 cells Concentration: 2.5 μM, 5 μM, 10 μM Incubation Time: 1.5 hours Result: Dose-dependently inhibited phosphorylation of IKKα/β and IκBα, and nuclear translocation of p65. Decreased the level of phosphorylated ERK1/2, JNK and p38 MAPK in activated ARPE-19 cells.
