We examined the effects of the extract from leaves of Liquidambar formosana Hance on S180 cells and screened for antitumor active sites in the plant. Solvent extraction was conducted to prepare extracts from the leaves of L. formosana Hance and conduct preliminary separation, an MTT assay to determine the effect of leaf extract on the proliferation of S180 cells, and inverted microscopy to observe the effect of chloroform extract on the morphology of S180 cells.

Mechanism of juglone-induced apoptosis of MCF-7 cells by the mitochondrial pathway

This study investigated the nature and mechanism of juglone-induced apoptosis in the human breast cancer cell line MCF-7. The inhibitory effect of juglone on MCF-7 cell growth was evaluated by the dimethylthiazol tetrazolium assay. Morphological apoptotic changes were characterized using an inverted microscope, Hoechst 33258 fluorescence staining, and Giemsa staining. The rate of cell apoptosis, intracellular levels of reactive oxygen species (ROS), and mitochondrial membrane potential were detected using flow cytometry.
