Representative flow cytometric profiles of A549 and U87MG cells treated with tocotrienols. The effects of (A) alpha-, (B) gamma- and (C) delta-tocotrienols on cell populations of untreated and treated A549 and U87MG cells at IC50 and IC80 concentrations for 48 h are shown. The fact with increased cell populations at the Pre-G1 phase of both treated A549 and U87MG cells confirms DNA fragmentation and apoptosis without doubt. α-T3: alpha-tocotrienol; γ-T3: gamma-tocotrienol; δ-T3: delta-tocotrienol.
