| 1 | Standardizing a simpler, more sensitive and accurate tail bleeding assay in mice显示文摘AIM: To optimize the experimental protocols for a simple, sensitive and accurate bleeding assay.METHODS: Bleeding assay was performed in mice by tail tip amputation, immersing the tail in saline at 37 ℃, continuously monitoring bleeding patterns and measuring bleeding volume from changes in the body weight. Sensitivity and extent of variation of bleeding time and bleeding volume were compared in mice treated with the P2 Y receptor inhibitor prasugrel at various doses or in mice deficient of Fc Rγ, a signaling protein of the glycoprotein VI receptor.RESULTS: We described details of the bleeding assay with the aim of standardizing this commonly used assay. The bleeding assay detailed here was simple to operate and permitted continuous monitoring of bleedingpattern and detection of re-bleeding. We also reported a simple and accurate way of quantifying bleeding volume from changes in the body weight, which correlated well with chemical assay of hemoglobin levels(r2 = 0.990, P < 0.0001). We determined by tail bleeding assay the dose-effect relation of the anti-platelet drug prasugrel from 0.015 to 5 mg/kg. Our results showed that the correlation of bleeding time and volume was unsatisfactory and that compared with the bleeding time, bleeding volume was more sensitive in detecting a partial inhibition of platelet's haemostatic activity(P < 0.01). Similarly, in mice with genetic disruption of Fc Rγ as a signaling molecule of P-selectin glycoprotein ligand-1 leading to platelet dysfunction, both increased bleeding volume and repeated bleeding pattern defined the phenotype of the knockout mice better than that of a prolonged bleeding time.CONCLUSION: Determination of bleeding pattern and bleeding volume, in addition to bleeding time, improved the sensitivity and accuracy of this assay, particularly when platelet function is partially inhibited. | Yang Liu Nicole L Jennings Anthony M Dart Xiao-Jun Du | 2012 | World Journal of Experimental Medicine2012,2,2: | 6 |

| 3 | MicroRNA-let-7a promotes E2F-mediated cell proliferation and NFKB activation in vitro显示文摘Epigenetic 因素,包括的改变的 microRNA (miRNA ) 表示,可以在全身的豺狼座 erythematosus (SLE ) 贡献异常有免疫力的房间功能。MiRNA-let-7a (let-7a ) 被显示了直接改变房间周期前进和 proinflammatory cytokine 生产。由于在房间分割和发炎的 let-7a 的关键角色,我们调查了 let-7a-mediated 增长和 NFκ在 J774A.1 巨噬细胞和 MES 的 B translocation 在 vitro 的 13 个 mesangial 房间。在有 let-7a 的刺激免疫者的房间 transfected,房间增长显著地随着时间的过去被增加。在 S 和 G 2 阶段的刺激免疫者的房间的数字有重要增加。刺激免疫者的房间 overexpressing let-7a 增加了 NFκ 的原子 translocation; B。Bioinformatical 分析表明 E2F 家庭, G 1-S 转变的批评管理者,在他们的 mRNA 抄本为 let-7a 有潜在的有约束力的地点。Let-7a overexpression 显著地增加了房间周期使活跃之物 E2F2 的表示并且在刺激免疫者的房间增加了 retinoblastoma 蛋白质(Rb ) phosphorylation。房间周期禁止者 E2F5 显著地在刺激免疫者的 let-7a-transfected 房间被减少。Bioinformatical 分析揭示了 E2F2 和 NFκ B 是预言调整 let-7a 倡导者的抄写因素。我们与 E2F2 和 NFκ 用染色质 immunoprecipitation 由即时 RT-PCR 分析了 let-7a 的 transcriptional 规定; B 抗体。E2F2 和 NFκ 有增加;在在刺激免疫者的房间为 let-7a 倡导者充实的 DNA 的 B 绑定。Silencing E2F2 或 NFκ B 显著地减少了在刺激免疫者的房间的 let-7a 表示和 IL-6 生产。一起拿,我们的结果建议 let-7a 的 overexpression 可以在 SLE 贡献增生和 proinflammatory 反应。 | Cristen B Chafin Nicole L Regna David L Caudell Christopher M Reilly | 2014 | Cellular & Molecular Immunology2014,11,1: | 3 |
| 4 | Changes in the colon microbiota and intestinal cytokine gene expression following minimal intestinal surgery显示文摘AIM: To investigate the impact of minor abdominal surgery on the caecal microbial population and on markers of gut inflammation.METHODS: Four week old piglets were randomly allocated to a no-surgery 'control' group(n = 6) or a 'transection surgery' group(n = 5).During the transection surgery procedure, a conventional midline incision of the lower abdominal wall was made and the small intestine was transected at a site 225 cm proximal to the ileocaecal valve, a 2 cm segment was removed and the intestine was re-anastomosed.Piglets received a polymeric infant formula diet throughout the study period and were sacrificed at two weeks post-surgery.Clinical outcomes including weight, stool consistency and presence of stool fat globules were monitored.High throughput DNA sequencing of colonic content was used to detect surgery-relateddisturbances in microbial composition at phylum, family and genus level.Diversity and richness estimates were calculated for the control and minor surgery groups.As disturbances in the gut microbial community are linked to inflammation we compared the gene expression of key inflammatory cytokines(TNF, IL1 B, IL18, IL12, IL8, IL6 and IL10) in ileum, terminal ileum and colon mucosal extracts obtained from control and abdominal surgery groups at two weeks post-surgery.RESULTS: Changes in the relative abundance of bacterial species at family and genus level were confined to bacterial members of the Proteobacteria and Bacteroidetes phyla.Family level compositional shifts included a reduction in the relative abundance of Enterobacteriaceae(22.95 ± 5.27 vs 2.07 ± 0.72, P < 0.01), Bacteroidaceae(2.54 ± 0.56 vs 0.86 ± 0.43, P < 0.05) and Rhodospirillaceae(0.40 ± 0.14 vs 0.00 ± 0.00, P < 0.05) following transection surgery.Similarly, at the genus level, changes associated with transection surgery were restricted to members of the Proteobacteria and Bacteroidetes phyla and included decreased relative abundance of Enterobacteriaceae(29.20 ± 6.74 vs 2.88 ± 1.08, P < 0.01), Alistipes(4.82 ± 1.73 vs 0.18 ± 0.13, P < 0.05) and Thalassospira(0.53 ± 0.19 vs 0.00 ± 0.00, P < 0.05).Surgeryassociated microbial dysbiosis was accompanied by increased gene expression of markers of inflammation.Within the ileum IL6 expression was decreased(4.46 ± 1.60 vs 0.24 ± 0.06, P < 0.05) following transection surgery.In the terminal ileum, gene expression of TNF was decreased(1.51 ± 0.13 vs 0.80 ± 0.16, P < 0.01) and IL18(1.21 ± 0.18 vs 2.13 ± 0.24, P < 0.01), IL12(1.04 ± 0.16 vs 1.82 ± 0.32, P < 0.05) and IL10(1.04 ± 0.06 vs 1.43 ± 0.09, P < 0.01) gene expression increased following transection surgery.Within the colon, IL12(0.72 ± 0.13 vs 1.78 ± 0.28, P < 0.01) and IL10(0.98 ± 0.02 vs 1.95 ± 0.14, P < 0.01) gene expression were increased following transection surgery.CONCLUSION: This study suggests that minor abdominal surgery in infants, results in long-term alteration of the colonic microbial composition and persistent gastrointestinal inflammation. | Susan Lapthorne Julie E Bines Fiona Fouhy Nicole L Dellios Guineva Wilson Sarah L Thomas Michelle Scurr Catherine Stanton Paul D Cotter Prue M Pereira-Fantini | 2015 | World Journal of Gastroenterology2015,21,14: | 3 |
