Antrodia camphorata, unique fungal specie, has been used as a folk medicine in Taiwan for many years. The purpose of this study was to compare the extracts from the solid-state culture of A. camphorata co-fermented with Chinese medicinal herb (AC-CF) with two other extracts from fruiting bodies (AC-FB) or solid-state culture (AC-SS), for their anti-tumor effects in human hepatoma HepG2 cells. We measured in vitro cell proliferation, percentage of apoptosis, population distribution of cell cycles, Western blot analysis of multiple drugs resistance-1 (MDR-1), and apoptosis-related proteins in HepG2 cells treated with three different preparations of A. camphorate extracts. Our results showed that AC-CF had better anti-proliferation effect on human hepatoma HepG2 cells than AC-FB or AC-SS dose-dependently. In addition, AC-CF in combination with anti-tumor agents (mitomycin C or methotrexate) showed better adjuvant anti-tumor effects than AC-FB or AC-SS. We further demonstrated the augmented adjuvant anti-tumor effects of AC-CF not only through down regulation of MDR-1 expression but also through a COX-2 dependent apoptosis pathway, involving down-regulation of COX-2 and p-AKT and up-regulation of PARP-1. In conclusion, in this study, we have demonstrated a novel strategy of fermenting A. camphorata with Chinese medicinal herb (AC-CF), which augmented their anti-tumor effects in human hepatoma HepG2 cells as compared to the traditional ones (AC-FB or AC-SS).
