AIM:To investigate the inhibitory effects of triptolide on cell proliferation and metastasis in Burkitt's lymphoma cell line Raji cells.METHODS: The effects of triptolide on the growth of Raji cells were studied by 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium(MTT) assay.The effects of triptolide on the cell apoptosis of Raji cells were detected by using Annexin Ⅴ/PI double-labled cytometry.The effects of triptolide on CXCR4 expression on Raji cells were studied by flow cytometric analysis.Chemotaxis assays were performed to observe the effects of triptolide on migration of Raji cells towards recombinant human SDF-1?(rhSDF-1?)in vitro.RESULTS: Triptolide inhibited the proliferation of Raji cells in a dose-and time-dependent way with a 24 h IC50 value of 43.06 nmol/L and a 36 h IC50 value of 25.08 nmol/L.Following the treatment of triptolide,the cell apoptosis rate was increased as the treatment concentration increased and the culture time extended.The effects were dose-and time-dependent.Triptolide could downregulate the expression of CXCR4 on Raji cells in a dose-dependent manner.Moreover,chemotaxis assay suggested that triptolide could block the migration of Raji cells to rhSDF-1? in vitro,and the inhibition was dose-dependent.CONCLUSION: Triptolide could inhibit the cell proliferation and induce the cell apoptosis of Raji cells.Furthermore,it could block the cell metastasis of Raji cells in vitro and the underlying mechanism might be related to the inhibition of the SDF-1/CXCR4 axis.

Caco-2 cell monolayer model is widely utilized in drug absorption study and 12-well transwellTM plates were commonly used to study the absorption of different kinds of natural products. To establish a stable method for the study of traditional Chinese medicine prescription, 6-well plates were chosen because of the larger well volumes than 12-well plates. To study the impacts of collagen kinds, coating density as well as coating time on the cell culture, the transepithelial electrical resistance of Caco-2 cell monolayers grown on different collagen coating transwells was determined, and the permeations of propranolol and atenolol as standard markers were detected with HPLC. The results showed that the kinds of collagen, the different coating densities and coating time of rat tail collagen had no significant influences on the Caco-2 cell monolayer integrality and absorption capacity. 6-well plates coated with 2 micro g Scm-2 rat tail collagen for 1 hour were enough reliable and suitable for the study of traditional Chinese medicine prescription in vitro.

Objective: To observe the effects of interferon-induced protein 204 (p204) over-expression on apoptosis, proliferation and migration of aortic vascular adventitial ifbroblast (VAFs) in experimental rats.
Methods: Our research included in 3 groups: Iif204-Lv group, in whichVAFs were infected by Iif204-recombined lentivirus, Con-Lv group, in which VAFs carried the empty vector without virus, Blank control group, in which VAFs were untreated. VAFs proliferation was examined by MTT method, cell apoptosis was measured by lfow cytometry and the migration was detected by scratching assay and transwell chamber method. The mRNA and protein expressions of p204, p53 and p21were evaluated by real-time q RT-PCR and Western blot analysis respectively.
Results: Compared with Con-Lv and Blank control groups, Iif204-Lv group had decreased VAFs proliferation (by OD value) at 48 hours: (0.53 ± 0.05) vs (0.66±0.03) and (0.63 ± 0.06), at 72 hours: (0.89 ± 0.06) vs (1.02 ± 0.06) and (1.01 ± 0.07); distance of cell migration (by pixel): (61.00 ± 1.83) vs (74.50 ± 6.25) and (75.50 ± 7.85); number of cell migration: (61.75 ± 10.69) vs (155.25 ± 10.21) and (153.75 ± 9.40), allP<0.05. VAFs apoptosis rates were similar among different groups. Compared with Con-Lv and Blank control groups, Ifi204-Lv group presented up-regulated mRNA expressions of p204 (3.45 ± 0.15) vs (2.09 ± 0.10) and (2.06 ± 0.09); p53 (3.41 ± 0.09) vs (2.06 ± 0.07) and (2.10 ± 0.06); p21 (3.01 ± 0.08) vs (2.05 ± 0.06) and (2.11 ± 0.08), allP<0.05.
Conclusion: p204 over-expression inhibits VAFs proliferation and migration which might be partly related to the activation of p53 and p21 expression in experimental rats.
