| 1 | Truncated Human LMP-1 Triggers Differentiation of C2C12 Cells to an Osteoblastic Phenotype in vitro显示文摘秘鲁利玛机场之代号矿化作用 protein-1 (LMP-1 ) 是被显示了在 vitro 并且在 vivo.LMP-1 导致骨头形成的新奇细胞内部的 osteoinductiveprotein 包含 anN 终端 PDZ 领域和三个 C 终端秘鲁利玛机场之代号领域。在这研究,我们调查了是否人的 LMP-1 的一种截断的形式( hLMP-l [ t ]),缺乏三个C终端秘鲁利玛机场之代号领域, weretransiently 触发 pluripotent myoblastic C2C12 房间的区别到造骨细胞 lineage.C2C12 房间有 Ad5-hLMP-l (t)绿色的 transduced 荧光灯的蛋白质和截断的蛋白质被检验。结果证明 thathLMP-l (t) 在 C2C12 文化堵住了 myotube 形成并且显著地提高了碱性磷酸酶(高山) 活动。另外,形态基因的蛋白质(BMP )-2 和 BMP-7 基因也是的高山, osteocalcin,和骨头的表情增加了。这些关键 osteogenic 标记的正式就职建议 hLMP-l (t)能触发 pluripotent myoblastic C2C12 房间区分 intoosteoblastic 系,因此扩大我们 LMP-1 和 LMP-1 (t)提高的以前的观察在房间的文化的 theosteoblastic 显型已经承诺了 osteoblasticlineage.Therefore , C2C12 房间是为 osteoblastic 显型和 LMP-1 行动的机制的学习感应的 LMP-1 的考试的一个适当模型系统。 | Qinming FEI | 2007 | Acta Biochimica et Biophysica Sinica2007,39,9: | 8 |
| 2 | LIM矿化蛋白-1抑制破骨前体细胞合成一氧化氮的分子机制研究显示文摘目的 探讨LIM矿化蛋白-1(LIM mineralization protein-1,LMp-1)抑制破骨前体细胞合成一氧化氮(nitric oxide,NO)的分子机制.方法 用不同浓度的TAT-LMP-1(0.05nmol/L,0.1 rimol/L,0.25 nmol/L)处理肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)或脂多糖(lipopolysaccharide,LPS)诱导的破骨前体细胞(RAW 264.7细胞),利用Greiss反应间接检测各组NO的生成量.用上述不同浓度的TAT-LMp-1处理LPS诱导的RAW 264.7细胞,使用逆转录-实时定量PCR和Western blot检测细胞中一氧化氮合酶(inducible NO synthase,iNOS)基因及蛋白的表达,利用Western blot检测细胞中NF-κB亚单位P65和磷酸化IκB含量,利用荧光素酶报告基因检测LMp-1对NF-κB通路转录活性的影响.结果 LMP-1可浓度依赖性抑制TNF-α或LPS诱导的RAW 264.7细胞合成NO.LMP-1可浓度依赖性抑制LPS诱导的RAW 264.7细胞中iNOS基因及蛋白的表达、NF-κB亚单位p65和磷酸化IκB含量升高以及NF-κB通路的转录活性.结论 LMp-1抑制LPS诱导的RAW 264.7细胞合成NO的可能分子机制为通过抑制IκB磷酸化使得p65不能与IκB解离,进而阻止p65核转移,导致NF-κB信号通路介导的iNOS生成障碍,最后引起NO生成减少. | 刘辉 Bargouti M 郑召民 张奎渤 Zughaier S 刘云山 Sangadala S Boden SD Titus L | 2011 | 中华骨科杂志2011,31,5: | 3 |
| 3 | Expression, purification and mass spectrometric analysis of LIM mineralization protein-1 in human lung epithelial cells显示文摘秘鲁利玛机场之代号矿化作用 protein-1 (LMP-1 ) 是被克隆并且出现在 vitro 并且在 vivo 导致骨头形成的新奇 osteoin-ductive 蛋白质。在 LMP-1 的糖类结构的可能的存在的察觉和评估是为 recombinantly 表示的蛋白质的治疗学的使用的重要规章的考虑。LMP-1 的顺序包含一个高度保存的 N 终端 PDZ 领域和三个 C 终端秘鲁利玛机场之代号领域。LMP-1 的顺序分析预言二个潜在的 N-glycosylation 地点和几个 O-glycosylation 地点。这里,我们报导克隆并且在在人的肺癌(A549 ) 的 LMP-1 的表示上房间。尽管我们的组已经报导了 LMP-1 cDNA 的顺序,我们拿了这个工作澄清是否过去表示蛋白质在 vivo 经历任何 glycosylation。表示全身的 recombinant 蛋白质被净化并且使遭到了到化学分析并且内部定序。在 LMP-1 蛋白质的化学作文分析的任何 hexosamines (N 乙酰 glucosamine 或 N 乙酰 galactosamine ) 的缺席表明有很少或在肺癌房间(A549 ) 的 LMP-1 多肽的没有 translational 以后 glycosylation。我们在净化的 LMP-1,和产生的肽上执行了在里面胶化胰岛素消化文摘被分析进一步的使用为肽质量的帮助矩阵的激光解吸附作用和电离团 spectrometry 手指打印,它与相应 LMP-1 肽生产了几准确匹配。由高效液体层析和定序的 N 终端跟随的需要的肽的纯化的分离为几净化的肽导致了许多准确 LMP-1 火柴,因此作为 LMP-1 建立净化的蛋白质的身份。 | Sreedhara Sangadala Louisa Titus Scott D.
