Abstrakt:	Objective: To investigate the effects of decitabine combined with bortezomib on the proliferation of mantle cell lymphoma cell lines (Jeko-1 and Grante519) in vitro and explore the underlying mechanisms. Methods: Jeko-1 and Grante519 cells were treated with different concentrations of decitabine and/or bortezomib alone and their combination.The cell proliferation was determined by CCK-8 assay. the cell apoptosis were detected by flow cytometry, the mRNA and protein expression levels of genes related with the cell cycle and apoptosis were analyzed by RT-PCR and Western blot respactively. Results: Low dose DAC could significantly inhibit the proliferation and induce apoptosis of Jeko-1 and Grante519 cells which shows a dose-and time-dependent manner. After DAC treatment, caspase 3, BAX and PCDH8 expression levels increased, while BCL-2 and CCND1 expression levels decreased in Jeko-1 and Grante519 cells, but there was no significant difference in NF-κB expression. High dose BTZ could significantly inhibit the proliferation and induce apoptosis of Jeko-1 and Grante519 cells which shows a dose-and time-dependent manner; single drug BTZ could increase the expression level of Caspase 3 and BAX, and decrease the expression level of NF-κB, BCL-2 and CCDN1 in Jeko-1 and Grante519 cells, but there was significant difference in PCDH8 expression level. Compared with single-drug treatment group, DAC combined with BTZ significantly increased the inhibitory rate and apoptotic rate of Jeko-1 and Grante519 cells; PCDH8, Caspase 3 and BAX expression levels significantly increased, and the expression levels of NF-κB, BCL-2 and CCND1 significantly decreased in Jeko-1 and Grante519 cells. Conclusion: The combination of DAC and BTZ has obviously synergistic effects on the growth inhibition of Jeko-1 and Grante519 cells which maybe relates with enhancing inbibitory effect on NF-κB signal pathway, down-regulating BAX expression, up-regulating BAX expression as well as increasing cospase 3 expression. This study provides a novel therapeutic approach for mantle cell lymphoma.
