Figure 7From: Cytotoxicity and apoptotic activities of alpha-, gamma- and delta-tocotrienol isomers on human cancer cells Western profiles of Bax protein expression in A549 and U87MG cells treated with tocotrienols. Following 4 h treatment period, Bax protein expression at a molecular size of 21 kDa reacted with anti-Bax antibody is detected in A549 and U87MG cells treated with alpha-, gamma- and delta-tocotrienols by which its density is higher than that of untreated counterparts. Beta-actin is served as a protein loading control. α-T3: alpha-tocotrienol; γ-T3: gamma-tocotrienol; δ-T3: delta-tocotrienol.Back to article page
