Our aim was to evaluate the antitumor activities of tocopherol (Toc) and tocotrienol (T3) derivatives. At first, we examined the effect of these vitamin E homologues on the proliferation of rat normal hepatocyte RLN-10 and hepatoma dRLh-84 cells and found that especially T3 inhibited cell proliferation in dRLh-84 cells. Then, we examined the effect of vitamin E homologues on apoptosis induction and found that T3 induced DNA fragmentation and stimulated a rise of caspase-3 activity. In addition, T3 stimulated a rise in caspase-8 activity, while a caspase-8 inhibitor suppressed apoptosis induction by T3. We also examined the incorporation of vitamin E homologues into dRLh-84 cells. T3 was incorporated more quickly compared to Toc. These results indicated that T3 induces apoptosis in dRLh-84 cells and that caspase-8 is involved in this apoptosis induction. The difference in terms of apoptosis induction by vitamin E homologues seems to be related to their different rates of cellular incorporation.
