title: [Effects of matrine on the apoptosis and expression of adhesion molecule in multiple myeloma RMPI8226 cells].
abstract: To investigate the effects of matrine on apoptosis and expression of adhesion molecules in human multiple myeloma cell line RPMI8226 cells, RPMI8226 cells were incubated with indicated concentrations of matrine. The growth of RPMI8226 cells was observed by CCK-8 colorimetric assay and apoptosis was detected by flow cytometry using Annexin V-FITC/PI staining. The cell cycles were analyzed by PI staining. Flow cytometry using Annexin V-FITC/PI staining was used to detect the expression of cell adhesion molecules, including CD44, CD44v6, CD54 and CD106. The results showed that RPMI8226 cell viability in presence of matrine decreased markedly in a dose- and time-dependent manners. The apoptosis could be induced by matrine and its level increased following the augmentation of the drug concentration. After treated by matrine for 48 hours, a concentration-dependent increase of cells in G(0)/G(1) phase and a decrease in S phase could be detected, but no obvious change of cell count was found in G(2)/M phase. Treatment of RPMI8226 cells with matrine for 48 hours resulted in decrease of expression levels of CD44 and CD54, while expressions of CD44v6 and CD106 had no significant change. It is concluded that matrine induces in vitro apoptosis, suppresses proliferation in multiple myeloma cells and depresses expression of some adhesion molecules.
