ABSTRACT
OBJECTIVE@#To investigate the effect and mechanism of a novel emodin derivative YX-18 on Burkitt lymphoma (BL) cells.@*METHODS@#MTT assay was used to detect the effect of YX-18 on the proliferation of BL cell lines CA46 and Raji. Annexin V-PE/7-AAD double staining assay was used for detecting the effect of YX-18 on the apoptosis of CA46 and Raji cells. PI/RNase staining was used to test the effect of YX-18 on CA46 and Raji cell cycle. JC-1 method was used to measure the changes of mitochondrial membrane potential after YX-18 treatment, and DAPI staining was used to detect the morphology of apoptotic cells. Western blot was used to analyze the distribution changes of NF-κB pathway protein (P65, P-P65, IκB, P-IκB) in the cytoplasm and cell nucleus, and also the expression changes of cyclin-related protein P21, CDK2, P-CDK2, Cycling D1, Cycling E1, and the apoptosis-related protein Caspase-3, Caspase-8, Caspase-9 and the proliferation-related protein C-MYC, BCL-2 by YX-18. Real-time fluorescence-quantitative PCR was used to evaluate the effects of YX-18 on mRNA levels of C-MYC and Ki-67 genes in CA46 and Raji cells, and EBNA-1 and EBER genes of EBV in Raji (EBV@*RESULTS@#Novel Emodin derivative YX-18 could effectively inhibit the proliferation of BL cell lines CA46 and Raji, showing a time-dependent effect (24, 48 and 72 h r@*CONCLUSION@#The novel emodin derivative YX-18 can significantly inhibit the proliferation of Burkitt lymphoma cells, and induce the cell apoptosis and cycle arrest. The inhibitory effect of YX-18 on the proliferation of Burkitt lymphoma cells may be related with the effect of Caspase apoptosis pathway, the proliferation and apoptosis-related molecules, such as C-MYC and Ki-67, and also to the inhibition of NF-κB pathway.
