Abstract:
This study was aimed to investigate the impact of specific siRNA on survivin gene in transfected lymphoma cell line and provide experimental evidences for future treatment of mantle cell lymphoma. The small interfering RNA (siRNA) targeted survivin mRNA was synthesized in vitro and was transfected into Jeko-1 that showed high survivin expression in mRNA level. The levels of survivin mRNA and protein expression were detected by quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot respectively. The apoptosis effect was examined by calculating the ratio of Annexin V-FITC/PI positive cells using flow cytometry. The inhibition of cell proliferation was assayed with CCK-8 reagent after transfection. The results showed that expression of survivin mRNA was markedly suppressed by the siRNA. The relative expression levels were 0.49 ± 0.03, 0.38 ± 0.02 and 0.17 ± 0.02 at time points of 24, 48 and 72 h respectively, compared with the control group; the inhibitive rates of cell proliferation were (31.2 ± 2.1)%, (43.3 ± 3.4)% and (52.6 ± 2.5)%; the apoptotic rates of cells were (6.3 ± 0.5)%, (13.5 ± 1.1)% and (23.6 ± 1.6)% respectively; survivin protein expression levels were gradually reduced. It is concluded that the siRNA targeting survivin down-regulates the expressions of survivin mRNA and protein evidently. The siRNA of survivin displays the potent ability to inhibit the proliferation of lymphoma cell line Jeko-1; survivin may become a potential molecular target for the therapy of lymphoma in the future.
