AIM: To explore whether the inhibitory effect of triptolide on IL - 1β production by PBMC is asso ciated with IL - 1β gene polymorphisms. METHODS: IL - 1β gene polymorphism was analyzed in 31 healthy volunteers. From genomic DNA, the C - T polymorphism at IL - 1 β - 511 was typed by PCR - RFLP. Meanwhile the IL - 1 β was also measured in the supernatants of the cultured and stimulated peripheral blood mononuclear cells (PBMC) by ELISA. RE SULTS: After LPS stimulation in PBMC cultures of healthy subjects, the secretion levels of IL - 1 β in 9 volunteers who carried IL - 1β -511 T/T genotype were higher than in volunteers who are not T/T genotype (P <0.05). Triptolide sup pressed the production of IL - 1β significantly in LPS - treated human PBMC carried C/C and C/T genotype ( P < 0.05 ), but this significant inhibitory effect of triptolide was not seen in T/T genotype ( P > 0.05 ). CONCLUSION: The gene polymorphism at IL - 1β - 511 was related to the production of IL - 1β, and the inhibitory effect of triptolide on the produc tion of IL - 1β was different in C/C, C/T, T/T genotype of IL - 1β -511, which may be one of the reasons for the phe nomenon that people respond differently to triptolide.

Objective:To study the relation between triptolide inhibit peripheral blood mononuclear cell to secret TNF-? and tumour necrosis factor-? gene polymorphism.Methods:Genomic DNA from 41 healthy people was typed for TNF-? -308 polymorphism by allele-specific polymorphism chain reaction(AS-PCR); the TNF-? concentration in the supernatant was measured by ELISA.Results:The TNF-? production of TNF-? -308 non-G/G genotype in LPS-inhibited peripheral blood mononuclear cell(PBMC) culture was more than that of G/G genotype; Compared with TNF-? -308 non-G/G genotype peripheral blood mononuclear cell(PBMC), triptolide can lower the production of TNF-? in G/G genotype peripheral blood mononuclear cell(PBMC).Conclusion:Tumour necrosis factor ?(TNF-?) gene polymorphism might influence the TNF-? secretion of peripheral blood mononuclear cell(PBMC) in healthy humans. We speculate that it may be relative to the different curative effect of Tripterygium Wilfordii Hook.F.(TWHF) to RA patients.

Objective To evaluate effects of simultaneous inhibition of mammalian target of rapamycin complex 1(mTORC1)kinase and glycogen synthase kinase-3β(GSK-3β)on phosphorylation of 4E-binding protein-1(4EBP1), cap-dependent translation, as well as survival and apoptosis of melanoma cells. Methods Cultured A375 cells were classified into several groups to be treated with dimethyl sulfoxide (DMSO group), the mTORC1 kinase inhibitor everolimus at a concentration of 5 nmol/L (everolimus group), the GSK-3β kinase inhibitor AR-A014418 at a concentration of 10 μmol/L (AR-A014418 group), or 5 nmol/L everolimus and 10 μmol/L AR-A014418(combined treatment group). After additional culture, Western-blot analysis was performed to measure protein expressions of phosphorylated 4EBP1 (p4EBP1)and survivin in A375 cells, m7GTP pull down assay to estimate interaction between eukaryotic initiation factor-4E (eIF4E)and eIF4G, cell counting kit 8 (CCK8)assay to evaluate cell proliferation, and flow cytometry to detect cell apoptosis. Results Both everolimus and AR-A014418 had inhibitory effects on 4EBP1 phosphorylation and survivin expression. The expressions of p4EBP1-65 and survivin were both significantly decreased in the everolimus group (0.74 ± 0.05 and 0.71 ± 0.06 respectively), AR-A014418 group (0.62 ± 0.06 and 0.58 ± 0.07 respectively)and combined treatment group (0.14 ± 0.04 and 0.09 ± 0.05 respectively)compared with the DMSO group (1.00 ± 0.07 and 1.00 ± 0.06, respectively, all P < 0.001), with the most significant decrease observed in the combined treatment group. As m7GTP pull-down assay showed, the everolimus group, AR-A014418 group and combined treatment group all showed significantly lower relative expression levels of eIF4G(0.72 ± 0.04, 0.67 ± 0.05 and 0.12 ± 0.05 vs. 1.00 ± 0.06, all P < 0.001), but significantly higher relative expression levels of 4EBP1 (1.98 ± 0.16, 2.32 ± 0.17 and 7.58 ± 0.25 vs. 1.00 ± 0.08, all P < 0.001)than the DMSO group, and the combined treatment group showed the lowest eIF4G expression but highest 4EBP1 expression. After 24-hour culture, the proliferation of A375 cells was inhibited by 18.5% ± 1.3% in the everolimus group, 19.8% ± 1.8% in the AR-A014418 group, and 61.2% ± 2.1% in the combined treatment group compared with the DMSO group, with the strongest inhibition noted in the combined treatment group. The inhibitory effects of everolimus and AR-A014418 on cell proliferation increased over time, and showed the same trend at 48 hours. Flow cytometry showed that the apoptosis of A375 cells was accelerated by the 24-hour treatments with everolimus and AR-A014418 alone or in combination, with the apoptosis rate being 14.28% ± 2.18%, 14.57% ± 2.35% and 55.18% ± 6.27% in the everolimus group, AR-A014418 group and combined treatment group respectively, and the combined treatment showed the strongest accelerating effect. Conclusion The combined treatment with everolimus and AR-A014418 can evidently inhibit 4EBP1 phosphorylation and eIF4F complex formation in A375 cells, which then suppress cap-dependent translation and promote apoptosis of melanoma cells.
