The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

OBJECTIVETo investigate the apoptosis effect of diffuse large B-cell lymphoma cell line (DLBCL) SUDHL-4 induced by IL-21 and its related mechanism.

METHODSSUDHL-4 cells were treated with IL-21 at different concentration (1000 ng/ml, 100 ng/ml, 10 ng/ml, 1 ng/ml) for 24 h, 48 h, 72 h, respectively. The inhibitory rate of cell proliferation was detected by CCK-8 assay. The cell growth curves were drawn and half inhibitory concentration (IC(50)) values were calculated. The cell apoptosis were detected by flow cytometry (FCM), the expression of the caspase-9, caspase-3, cleaved caspase-3, Bcl-2, Bcl-XL, Bid, Bax and c-myc protein in SUDHL-4 cells treated with IL-21 by western blot, the mRNA expression of Bcl-2, Bcl-XL, Bid, Bax, c-myc by Survivin gene with RT-PCR.

RESULTSIL-21 markedly inhibited SUDHL-4 cell growth in a time- and dose-dependent manner. The 48 hIC(50) was 140.9ng/ml; The FCM showed that the apoptosis proportion of SUDHL-4 cells treated with 100 ng/ml of IL-21 apoptosis (AnnexinV-FITC(+) positive cells) gradually increased (48 h: 19.7 ± 2.3%). The protein expression of caspase-9, caspase-3, Bcl-2 and Bcl-XL decreased in a time-dependent manner. The Bax and c-myc protein markedly increased, but the Bid protein level did not change. IL-21 up regulated c-myc and Bax gene expression, however down regulated Bcl-2 and BCL-XL gene expression, but the gene expression of Bid and Survivin hadn't been changed significantly.

CONCLUSIONSIL-21 can inhibit proliferation and induce apoptosis of SUDHL-4 cell. The mechanism may involve in endogenous mitochondrial pathway mediated by the c-myc and the Bcl-2 genes.

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.
