Objectives : This study was carried out to evaluate whether the water extract from cause the cellular damage in HepG2 cell line. It was reported that Dictamnus dasycarpus Turcz(DDT) intake induce poisoning symptoms in human population. These symptoms was closely related to liver toxicity, however, mechanisms for liver toxicity caused by DDT have not been elucidated exactly. Here, hepatotoxicity caused by DDT was evaluated using HepG2 cell line.
Methods : Water extract of DDT was treated into HepG2 cell with various doses such as 0, 0.1, 0.5, 1.0 and 5.0 ㎎/㎖. In order to cell viability, both MTT and LDH assay were carried out. Also, apoptosis array kit was used to identify whether cell death caused by DDT is due to apoptosis or not. In addition, reactive oxygen species (ROS) was measured after treatment of water extract.
Results : We found out significant changes in the apoptosis related factors of hepatocyte. The cell viability of HepG2 treated with DDT water extract was decreased in dose-dependent. Also most of the apoptosis related factors were significantly increased. We found out that Caspase 3, Cytochrome C and ROS had increased in dose-dependent. In addition, other apoptosis related factors Bcl 2 and Bax, which were also constant changes. However, there was no significance.
Conclusions : These results suggest that water soluble extract of DDT is expected to have oral toxicity, including hepatocellular damage Therefore, it is suggested that DDT could cause various side effects and toxicity of clinical conditions.
