Glycyrrhiza species possess preventive and therapeutic potentials against various cancers. In the present study, we have evaluated regulation of apoptotic cell death by aqueous extracts of leaf and flower of an endemic Glycyrrhiza species; Glycyrrhiza flavescens subsp. antalyensis, in mouse melanoma cell lines. Both leaf and flower extracts induced apoptosis in terms of induction of caspase-3 activity, TNF-alpha and IFN-gamma release. Concentrations of both TNF-alpha and IFN-gamma in extract-treated groups were significantly and dose dependently exalted as compared to their relative controls. The effects of extracts on caspase-3, TNF-alpha and IFN-gamma processes mediate the plausible mechanism of apoptosis induction of G. flavescens subsp. antalyensis. (C) 2010 Elsevier Ltd.
