Effects of Low-Dose versus High-Dose γ-Tocotrienol on the Bone Cells Exposed to the Hydrogen Peroxide-Induced Oxidative Stress and Apoptosis

Figure 5

The effects of H₂O₂ and γ-tocotrienol on the caspase-3 activity in osteoblasts. Osteoblasts were pretreated with 1, 10, and 100 μM 𝛾-tocotrienol for 24 hours before treated with 490 μM H₂O₂ for 2 hours. The groups that have the same alphabet symbols (a, b, c) are not significantly different from each other (𝑃<0.05). Data are presented as mean±SEM, 𝑛=3.
