The licorice (root of Glycyrrhiza glabra) inhibited dopaminergic apoptotic cell death as evidenced in the increase in Bcl2 levels and in the decrease in Bax levels, caspase-3 activity, cytochrome c release, and JNK and MAP activities in a model of 6-OHDA-induced Parkinson's disease [121]. This evidence concerns the gene CYCS and Parkinson disease.
