  ABSTRACT: Aim: To study the antitumor mechanism of OSW-1 in hepatocellular carcinoma. Materials and Methods: The expression profiling microarray was carried out to extract RNA from SK-Hep-1 which suffered from OSW-1. ρ0-SK-Hep-1 was maintained SK-Hep-1 in MEM containing 100 μg/L ethidium bromide (EB), 1 mM sodium pyruvate and 50 μg/ml uridine for 40 days. Then confirmed COX-I and COX-II of mitochondrial DNA were knocked out. Cells suffered from OSW-1 or doxorubicin. Then cells were washed twice with cold PBS and incubated with DCFH-DA. Fluorescent signal was recorded by using Infinite 200 Pro multimode Plate readers. Results: OSW-1 elevates generation of ROS and Cytochrome C which are associated with the induction of apoptosis in SK-Hep-1 cells. We also demonstrate that OSW-1 does not depend on p53 to up-regulate the BH3-only protein Noxa. What is more noteworthy that the Caspase-9 and FADD are down-regulated in above process. Conclusion: OSW-1 induced special apoptosis is different from the mitochondrial death pathway and the death receptor pathway and final result is not Caspase family’s activating. This provides a novel theory that nonmalignant cells are significantly less sensitive to OSW-1 than cancer cell lines.
