This study determines the influence of transformed root (TR) extract of Leonurus sibiricus L. on various grades (I-III) of human glioma cells derived from patients. This plant occurs in southern Asia and Siberia and is widely used as a medicinal plant with various biological activities. Chromatographic profile of TR extract have revealed the presence of various polyphenolic compounds (4-hydroxybenzoic acid, gentisic acid, vanilic acid, 1,3-dicaffeoylquinic acid, alpha-resorcylic acid). We found TR root extract to have antiproliferative activity on glioma cells after 24 h of treatment. TR root extract induces apoptosis on various grades (I-III) of human glioma cells by the generation of reactive oxygen species (ROS) along with concurrent loss of mitochondrial membrane potential, enhanced S and G2/M phases of the cell cycle, and altered mRNA levels of Bax, Bcl-2, p53, Cas-3, Cas-8 and Cas-9 factors involved in apoptosis. This work for the first time demonstrate that TR extract from L. sibiricus root has the potential to activate apoptosis in grade I-III human glioma cells through the intrinsic and extrinsic pathways.
