[Objectives] To explore the inhibitory effect of octadecadienoic acid (ODA) on proliferation and apoptosis of glioma cells and its mechanism. [Methods] Cultured human glioma cells (cell density 2×10^(6) cells/L) were divided into three groups: solvent control group (DMSO, 30 μL/L), 5-FU group (10 mg/L) and octadecadienoic acid group (0.3, 0.6, 1.2 mg/L). The toxic effects of ODA on glioma cells were detected by trypan blue and thiazolium blue (MTT). The expression of P53, PI3K, P21, PKB/Akt and caspase-9 protein in glioma cells were detected by enzyme-linked immunosorbent assay (ELISA). [Results] The cell count under optical microscope showed that the inhibition rate of cell proliferation in low, medium and high dose ODA groups and 5-FU group was significantly higher than that in solvent control group ( P 0.05). The results of MTT showed that compared with the solvent control group, the inhibition rate of cell proliferation in low, medium and high dose ODA groups and 5-FU group significantly increased ( P <0.01);compared with 5-FU group, the inhibition rate of cell proliferation in high dose ODA group significantly increased ( P <0.01). The results of flow cytometry showed that compared with the solvent control group, the number of cells in G_(0)/G_(1) phase increased significantly ( P <0.05, P <0.01), the number of cells in G_(2)/M phase decreased significantly ( P <0.01) and the apoptosis rate increased significantly ( P <0.01) in the low, medium and high dose ODA groups and 5-FU group;compared with 5-FU group, the number of cells in G_(2)/M phase decreased significantly ( P <0.01) and the apoptosis rate increased significantly ( P <0.01) in ODA group. ELISA testing results showed that the expression levels of P53, P13K and PKB/Akt in low, medium and high dose ODA groups and 5-FU group were significantly lower than those in solvent control group ( P <0.01), and only the expression level

BACKGROUND The investigation of plant-based therapeutic agents in medicinal plants has revealed their presence in the extracts and provides the vision to formulate novel techniques for drug *** negundo(***),a perennial herb belonging to the Varbanaceae family,is extensively used in conventional *** To determine the existence of therapeutic components in leaf and callus extracts from wild *** plants using gas chromatography-mass spectrometry(GCMS).METHODS In this study,we conducted GC-MS on wild plant leaf extracts and correlated the presence of constituents with those in callus *** growth regulators such as 6-benzylaminopurine(BAP),2,4-dichlorophenoxyacetic acid(2,4-D),α-naphthylacetic acid(NAA),and di-phenylurea(DPU)were added to plant leaves and in-vitro callus and grown on MS *** The results clearly indicated that the addition of BAP(2.0 mg/L),2,4-D(0.2 mg/mL),DPU(2.0 mg/L)and 2,4-D(0.2 mg/mL)in MS medium resulted in rapid callus *** plant profile of Vitex extracts by GC-MS analysis showed that 24,10,and 14 bioactive constituents were detected in the methanolic extract of leaf,green callus and the methanolic extract of white loose callus,*** octadecadienoic acid,hexadecanoic acid and methyl ester were the major constituents in the leaf and callus methanolic *** acid was the most common constituent in all *** maximum concentration of octadecadienoic acid in leaves,green callus and white loose callus was 21.93%,47.79%and 40.38%,*** findings demonstrate that the concentration of octadecadienoic acid doubles in-vitro compared to *** addition to octadecadienoic acid;butyric acid,benzene,1-methoxy-4-(1-propenyl),dospan,tridecanedialdehyde,methylcyclohexenylbutanol,chlorpyrifos,n-secondary terpene diester,anflunine and other important active compounds were also *** these components were only available in callus formed in-vit
