In Taiwan, 2009, cancer is a leading cause of death, and liver cancer is the second leading cause of all cancer deaths. Therefore, how to keep the liver healthy is a big issue in Taiwan. Recently, research has shown that Antrodia cinnamomea contains many active compounds which can manipulate biological activities, including liver protection, anti-cancer, anti-inflammation, and regulation of the immune system. Although studies using both cell and animal models have shown that the fruiting body of Antrodia cinnamomea has anti-cancer effects, its active compounds with anti-liver cancer activity and the exact mechanism are still unclear. In this study, the Hep 3B hepatoma cells will be used to investigate the anti-liver cancer activity of the active compounds in the fruiting body of Antrodia cinnamomea, including “eburicoic acid and dehydroeburicoic acid” belonged to triterpenoids, “antcin B and antcin C” belonged to steroids, and "7-hydroxy-4-methoxy-5-methyl-1,3-benzodioxole” belonged to aromatic compounds. In addition, the anti-liver cancer mechanisms of these compounds will be studied. This project will be completed in two parts/years. In the first part, we will investigate the anti-liver cancer activity of the fruiting body of Antrodia cinnamomea, and its various active compounds. In the second part, we will study the potential mechanisms,such as regulation of cell cycle, necrosis and apoptosis, and particularly autophagy. The rat primary hepatic cell will be used to evaluate the anti-liver-protection effects of the compounds of Antrodia cinnamomea on normal cells. Hopefully, the main active compounds with anti-liver cancer activity from the fruiting body of Antrodia cinnamome will be found and used as an important reference for health food development.肝癌牛樟芝子實體三類固醇類芳香族細胞壞死細胞凋亡自體吞噬liver cancerfruiting body of Antrodia cinnamomeatriterpenoidssteroidsaromatic compounds,牛樟芝子實體中抗肝癌活性成分之探討
