Abstract
Atherosclerosis is a chronic inflammatory disease of the vascular walls. ApoCIII is an independent factor which promotes atherosclerotic processes. This study aimed to investigate whether Loganin administration inhibits the inflammatory response in vitro and in vivo. In the apoCIII-induced mouse adipocytes, the levels of cytokines, including TNF-α, MCP-1 and IL-6 were determined by enzyme-linked immunosorbent assay and their gene expressions were measured through RT-PCR. The phosphorylation of nuclear factor-κB (NF-κB) proteins was analyzed by Western blotting. Our results showed that Loganin markedly decreased TNF-α, MCP-1 and IL-6 concentrations as well as their gene expressions. Western blotting analysis indicated that Loganin suppressed the activation of NF-κB signaling. In the Tyloxapol-treated mouse model, Loganin reduced the contents of TC and TG in mouse serum. The results of Oil Red-O Staining showed that Loganin reduced the production of lipid droplets. So it is suggested that Loganin might be a potential therapeutic agent for preventing the inflammation stress in vitro and in vivo.

[PMID: 26407655 DOI: 10.1016/j.ejphar.2015.09.019] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2015] [Revised: 09/09/2015] [Accepted: 09/14/2015] [Indexed: 12/27/2022]
Abstract
Acute pancreatitis (AP) is an inflammatory disease of the pancreas, which, in its most severe form, is associated with multi-organ failure and death. Loganin, a major iridoid glycoside obtained from Corni fructus, has been shown to have anti-inflammatory and anti-shock effects. However, the effects of loganin on AP have not been determined. Pre-treatment of loganin reduced pancreatic damage and AP-associated lung injury and attenuated the severity of AP, as evidenced by (1) a reduction in several biochemical parameters (pancreatic weight to body weight ratio, myeloperoxidase activity, and level of amylase) and (2) production of pro-inflammatory cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF)-α. However, post-treatment of loganin failed to improve pancreatic damage and biochemical parameters of AP, but could inhibit the AP-induced elevation of IL-1β and TNF-α significantly. In addition, cerulein-induced activation of nuclear factor (NF)-κB was inhibited in the pancreas by administration of loganin. In conclusion, these results suggest that loganin exhibits an anti-inflammatory effect in cases of AP and its pulmonary complications through inhibition of NF-κB activation.
