Objective:To observe the effects of matrine on proliferation and apoptosis of human lymphoma cell line Raji in vitro
and to explore its mechanism.Methods:The proliferation inhibition rate of Raji cells was assayed by MTT analysis.Cell apoptosis rate was evaluated by flow cytometry.The expression level of Bcl-2 protein was evaluated by streptavidin-biotin-peroxidase method.The Bcl-2 mRNA expression of Raji cells treated with matrine was assayed by RT-PCR.Results:The matrine of different concentrations all had cytotoxic effects on Raji cells
in a dose-and time-dependent manner.The apoptosis induced by matrine was confirmed in Raji cells. Immunocytochemistry assessment showed the expression of Bcl-2 was significantly down-regulated after treated with matrine.The Bcl-2 mRNA expression in Raji cells was decreased after treated by matrine
with a concentration-effect relationship.Conclusion:Matrine can inhibit the proliferation of Raji cells significantly.By down-regulating the expression of Bcl-2 and inducing the apoptosis.
