TP extracts induced apoptosis in human melanoma cells. Effect of TP extracts on the cellular sub-G1 and DNA content. The cells were treated with 20 μg/ml of TP (TP1g–TP7) extracts for 6 h and stained with PI as described in Materials and Methods. Following flow cytometric analysis, cellular DNA profiles were further analyzed by Cell Quest software. Results are from one experiment but are representative of three similar experiments.
