Abstract:
Objectives:To investigate the differentiation of human hepatocellular carcinoma cell line Bel-7404 induced by Matrine in vitro,and discuss its mechanism.Methods:After dealing human hepatocellular carcinoma cell line Bel-7404 with different concentrations of Matrine,we drew cell growth curve by MTT colorimetry,and cell morphology was examined by light microscope.Then we evaluated the tumor cell biological characteristics changes through improved soft agarose clone forming test,cell adhesion assay,cell movement assay and cell invasion assay.Also we detemined cell cycle distributing by flow cytometry.Results:After 72 hours being treated with 0.5,0.75,1.0g/L,in the Matrine test groups,the cell proliferation was inhibited significantly,and cell shape transformed to normal.The amounts of clone were remarkably reduced.The cell adhesion ability increased in different level.At the same time cell ability of movement and invasion differently weakened.Analysis of cell cycle shown that along with rising of Matrine concentration,the cell amounts in G1 phase increased accordingly and cell amounts in G2 and S phase remarkbly decreased.Conclusion:During the appropriate concentration range,Matrine not only inhibited Bel-7404 growth and proliferation,but also induced tumor cell to differentiate.Its probably mechanism may related to cell cycle regulation.
