Chlorogenic acid attenuates liver apoptosis and inflammation in endoplasmic reticulum stress-induced mice.

Abstract

Objectives: The accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER)results in a state known as "ER stress". It can affect the fate of proteins and play a crucial role in the pathogenesis of several diseases. In this study, we investigated the protective effect of chlorogenic acid (CA) on the inflammation and apoptosis of tunicamycin-induced ER stress in mice. Materials and Methods: We categorized mice into six groups: Saline, Vehicle, CA, TM, CA 20-TM, and CA 50-TM. The mice received CA (20 or 50 mg/kg) before intraperitoneal tunicamycin injection. After 72 hr of treatment, serum biochemical analysis, histopathological alterations, protein and/or mRNA levels of steatosis, and inflammatory and apoptotic markers were investigated by ELISA and/or RT-PCR. Results: ), of liver tissue in ER stress mice. Conclusion: These data suggest that CA ameliorates hepatic apoptosis and inflammation by reducing NF-κB and Caspase 3 as related key factors between inflammation and apoptosis.
