Abstract
Artemisia capillaris Thunb. has been used for the remedy of liver diseases such as hepatitis, jaundice and fatty liver in traditional oriental medicine. However, despite extensive pharmacological studies, the molecular mechanism of the anti-inflammatory effect of Artemisia capillaris Thunb. has hardly been studied. In the present study, we investigated the pharmacological action mechanism on LPS-induced liver inflammation in HepG2 human hepatocarcinoma cells and rat liver. Aqueous extract from Artemisia capillaris Thunb. (AEAC) inhibits expression of inflammatory proteins including iNOS, COX-2 and TNF-α. Also, nuclear translocation of NF-κB and degradation of I-κBα are blocked by AEAC pretreatment. These results suggest that the inhibitory effect of AEAC on the expression of inflammatory proteins involves suppression of NF-κB activation.
