ABSTRACT
OBJECTIVE@#To explore the regulatory effect of TRIP13 on the proliferation and apoptosis of B-cell lymphoma cells and its possible molecular mechanism by knocking down/overexpressing TRIP13 on the cell lines Granta-519 and JVM-2.@*METHODS@#Lentiviral transfection technology was used to construct Granta-519 and JVM-2 cells with knocked down or overexpressed TRIP13 and their control cells. The efficiency of transfection was determined by fluorescence microscopy. The efficiency of knockdown and overexpression was evaluated by real-time quantitative PCR and Western blot. The proliferation was detected by CCK-8 assay. The apoptosis was detected by the Annexin V-APC single staining. The cell cycle was detected by the PI staining. The expression levels of P53, MDM4, and BCL-2 were evaluated by Western blot.@*RESULTS@#After TRIP13 was knocked down, the proliferation ability of Granta-519 and JVM-2 cells was significantly reduced, and the apoptosis rate significantly increased. After TRIP13 was overexpressed, the proliferation ability of Granta-519 and JVM-2 cells was significantly enhanced, and the apoptosis was significantly reduced. After TRIP13 was knocked down, Granta-519 cells had obvious G@*CONCLUSION@#TRIP13 promotes the proliferation of B-cell lymphoma cells, inhibits their apoptosis, and affects their proliferation and apoptosis by participating in the regulation of the cell cycle. TRIP13 promotes the expression of BCL-2 proteins and inhibits the expression of MDM4 protein in B-cell lymphoma cells.
