Effect of Saponins in Pulsatillae Radix on Proliferation and Apoptosis of NCI-H460 Lung Cancer Cells and Screening of Its Differentially Expressed Proteins
To screen the differentially expressed proteins of saponins in Pulsatillae Radix inhibiting the proliferation and induce apoptosis on NCI-H460 tumor cells based on proteome technology using nano LC-LTQ-Orbitrap-MS/MS
and preliminarily speculate the potential mechanism.
Method:
2
NCI-H460
SK-OV-3 and SGC-7901 tumor cells were cultured
in vitro
. Methylthiazoletetrazolium (MTT) assay was used to detect the inhibitory rate of saponins in Pulsatillae Radix on three tumor cell lines. Effect of saponins in Pulsatillae Radix on apoptosis was analyzed by Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) staining flow cytometry and 4′
6-diamidino-2-phenylindole (DAPI) staining. Apoptosis was analyzed using flow cytometry and DAPI stain. Nano LC-LTQ-Orbitrap-MS/MS was used to investigate the changes in the protein profiles on NCI-H460 cells treated with saponins in Pulsatillae Radix. Proteins exhibiting differential expression were analyzed by DAVID Bioinformatics Resources 6.8 and Kyoto encyclopedia of genes and genomes (KEGG) database. The differentially expressed proteins were verified by Western blot.
Result:
2
Saponins in Pulsatillae Radix could inhibit the proliferation of NCI-H460
SK-OV-3 and SGC-7901 tumor cells and induce apoptosis of NCI-H460 tumor cells. Effect of Saponins in Pulsatillae Radix on the proliferation and apoptosis of NCI-H460 tumor cells was mainly related to the regulation of biological function of ribosome
glycolysis/gluconeogenesis and other biological processes. It was possible to induce apoptosis of NCI-H460 tumor cells by interfering mitogen-activated protein kinase (MAPK) signaling pathway and regulating the Caspase pathway.
Conclusion:
2
Saponins in Pulsatillae Radix can inhibit the proliferation and induce the apoptosis of NCI-H460 tumor cells
the mechanism may be related to the intervention of MAPK signaling pathway and the regulation of Caspase pathway. These findings are helpful to elucidate the molecular mechanism of the anti-tumor effect of saponins in Pulsatillae Radix.
