Application of ɑ-Tocotrienol-Loaded Biocompatible Precirol in Attenuation of Doxorubicin Dose-Dependent Behavior in HUH-7 Hepatocarcinoma Cell Line. Nutrition and cancer, 2020, Volume: 72, Issue:4 Tumor-targeted nanoparticle delivery system has been known as a substitute and capable achievement in cancer treatment compared to conventional methods. In this study, we examined potential application of ɑ-tocotrienol-Precirol formulation to enhance efficiency of doxorubicin (DOX) in induction of apoptosis in HUH-7 hepatocarcinoma cells. ɑ-tocotrienol-loaded nanoparticles were characterized at the point of zeta potential, particle size, scanning electron microscope (SEM), and cell internalization. To evaluate antiproliferative effects of formulation, apoptosis, cell cycle procedure, flow cytometry, and MTT assays were employed. Optimum size of the ɑ-tocotrienol formulation revealed narrow size distribution with mean average of 78 ± 3 nm. IC Topics: Apoptosis; bcl-2-Associated X Protein; Carcinoma, Hepatocellular; Cell Line, Tumor; Diglycerides; Dose-Response Relationship, Drug; Doxorubicin; Drug Compounding; Humans; Liver Neoplasms; Nanoparticles; Survivin; Tocotrienols	2020
Apoptosis induction by gamma-tocotrienol in human hepatoma Hep3B cells. The Journal of nutritional biochemistry, 2006, Volume: 17, Issue:10 We evaluated the antitumor activity of tocotrienol (T3) on human hepatoma Hep3B cells. At first, we examined the effect of T3 on the proliferation of human hepatoma Hep3B cells and found that gamma-T3 inhibited cell proliferation at lower concentrations and shorter treatment times than alpha-T3. Then, we examined the effect of gamma-T3 apoptosis induction and found that gamma-T3 induced poly (ADP-ribose) polymerase (PARP) cleavage and stimulated a rise in caspase-3 activity. In addition, gamma-T3 stimulated a rise in caspase-8 and caspase-9 activities. We also found that gamma-T3-induced apoptotic cell death was accompanied by up-regulation of Bax and a rise in the fragments of Bid and caspase-8. These data indicate that gamma-T3 induced apoptosis in Hep3B cells and that caspase-8 and caspase-9 were involved in apoptosis induction. Moreover, these results suggest that Bax and Bid regulated apoptosis induction by gamma-T3.
