“…Thus a better understanding of the diverse modes of cell death in cancer therapy will provide a molecular basis for new strategies targeting death pathways. A wide range of putative cancer-chemopreventive plant extracts in particular Glycyrrhiza uralensis, Sologrum nigrum, Pereskia bleo, Cratoxylum cochinchinense, Rhodiola rosea, Physalis peruviana, Betulla platyphylla (Jo et al, 2005;Ju et al, 2004;Majewska et al, 2006;Tan et al, 2005;Tang et al, 2004;Wu et al, 2004) has been suggested to induce apoptosis in neoplastic cells (Table 3). The apoptotic effect of the ethanolic extract of P. peruviana in human HepG2 cells resulted from the collapse of the mitochondrial membrane permeability and depletion of glutathione .…”
