| 1 | Expression, purification, and functional characterization of recombinant PTD-SARA显示文摘为蛋白质是的受体激活(SARA ) 的 Smad 锚为在支持发信号的小径的 fibrotic 起一个重要作用的 Smad2/3 的一个有约束力的搭挡由转变生长 factor-1 (TGF-1 ) 开始了。C 终端 SARA 的 665750 aa 包括 Smad 有约束力的领域(SBD ) 。由通过 SBD 的直接相互作用, SARA 禁止 Smad2/3 phosphorylation 并且堵住在 Smad2/3 和 Smad4 之间的相互作用,从而制止纤维变性的过程。在这研究,我们基于 SBD 顺序构造了 SARA 肽 aptamer。recombinant SARA aptamer,与一个蛋白质 transduction 领域(PTD-SARA ) 熔化了,被克隆,从 E 净化了。coli,并且第一次描绘了。编码顺序的全身的 PTD-SARA,与 E 创造了。coli 赞成了 codons,被克隆进 pQE-30 向量,并且 recombinant plasmid 被转变成 M15 紧张。在 Isopropyl -D-1-Thiogalactopyranoside (IPTG ) 以后正式就职和 Ni2+ 亲密关系纯化, recombinant PTD-SARA 被定序的 immunoblotting 和蛋白质 N 终端进一步识别。Epifluorescence 显微镜学表明 recombinant PTD-SARA 比 SARA 更高效地被变成细胞质和原子核。而且, recombinant PTD-SARA 被发现 E-cadherin 和下面调整的水平到起来调整 -SMA 和 phospho-Smad3 的层次更高效地比 SARA (P < 0.05 ) 。我们的工作探索了一个方法获得 recombinant PTD-SARA 蛋白质。recombinant PTD-SARA 熔化蛋白质能进入 HK2 房间(使不朽的近似小管上皮的房间线) 更高效地比 SARA 蛋白质和颠倒被 TGF-1 比 SARA 蛋白质更有效地导致的肾的 epithelial-to-mesenchymal transdifferentiation 过程。Recombinant PDT-SARA 是可能的是肾的纤维变性的临床的预防和处理的一个潜在的候选人。 | Chen Huang Rui Du Peng Zhang Hua Meng Huiwei Jia Yang Song Man Li Yingqi Zhang Shiren Sun | 2011 | Acta Biochimica et Biophysica Sinica2011，43，2： | 4 |
| 2 | Effect of the hyaluronic acid-poloxamer hydrogel on skin-wound healing: in vitro and in vivo studies显示文摘Background: Recent research into skin injury and wound healing has focused mainly on post‐trauma hemostasis, infection prevention, dermal regeneration and angiogenesis. However, less attention has been paid to air permeability and moisture loss prevention which also play important roles in injury healing. Methods: In the present work, we prepared a hyaluronic acid‐poloxamer (HA‐POL) hydrogel and tested the therapeutic effect of the hydrogel on skin‐wound healing. Results: The HA‐POL hydrogel transformed from sol to gel at 30°C, close to body temperature, and had stable moisturizing properties. HA‐POL hydrogel promoted skin‐wound healing and increased protein accumulation in the wound area. HA‐POL hydrogel allowed greater air permeability than Band‐aid, a typical wound covering. Results from transwell assays showed that the HA‐POL hydrogel effectively isolated skin‐wounds from bacterial invasion. Conclusion: This work demonstrates the advantages of using HA‐POL gel materials in the treatment of cutaneous wounds. | Xiaojuan Li Aimin Li Fan Feng Qiyu Jiang Huiwei Sun Yantao Chai Ruichuang Yang Zhijie Wang Jun Hou Ruisheng Li | 2019 | Animal Models and Experimental Medicine2019，2，2： | 1 |
| 3 | Quantitative examination of the inhibitory activation of molecular targeting agents in hepatocellular carcinoma patient-derived cell invasion via a novel in vivo tumor model显示文摘Background: The outcomes for patients with advanced hepatocellular carcinoma(HCC) receiving sorafenib are far from satisfactory because of treatment resistance to sorafenib. However, the exact mechanism of resistance to sorafenib remains unclear and it is valuable to establish a novel mouse model to quantitatively analyze the inhibition rates of sorafenib on the invasive growth of HCC cells in the liver.Methods: HCC tissue microblocks derived from patients were cultured and mixed with hydrogel drops. Then, hydrogel drops containing microblocks of HCC tissue were attached onto the surface of the livers of nude mice to form lesions or nodules of HCC. The mice received molecular targeting agents through oral administration. Livers with tumor nodules were harvested for H&E staining(hematoxylin-eosin staining) analysis and H&E staining images were quantitatively analyzed using image J software. The invasive growth of HCC cells into the liver was calculated using the depth of the lesions compared with the total thickness of the liver.Results: Microblocks containing cells derived from HCC patients can form lesions in the liver of nude mice. Oral administration of molecular targeting agents inhibited the invasive growth of HCC cells in the liver of nude mice.Conclusions: The model established in this study involves the invasive growth of HCC cells in the liver of nude mice, and the model allows for the quantitative analysis of the inhibitory effect of molecular targeting agents on the invasion of HCC cells in vivo. | Huiwei Sun Fan Feng Hui Xie Xiaojuan Li Qiyu Jiang Yantao Chai Zhijie Wang Ruichuang Yang Ruisheng Li Jun Hou | 2019 | Animal Models and Experimental Medicine2019，2，4： | 1 |
| 4 | Effect of Combined Foliar Spray on Heavy Metals Accumulation in Facility Fruit Vegetables显示文摘In order to explore the effects of combined foliar spray which was prepared from potassium fulvate and Zn on heavy metal accumulations in three kinds of facility fruit vegetables,cucumber,tomato and white melon,the foliar spray was applied from fruit setting to maturation.The results showed that the combined foliar spray significantly promoted the absorption of Zn and Cu in the three fruit vegetables,blocked the absorption of Cr,As and Pb in cucumber,significantly blocked the absorption of Cd in white melon,blocked the absorption of Pb in white melon,and showed a tendency of blocking the absorption of heavy metals Cd and As in tomato. | Huiwei ZHAO Jumei LI Xueping SHI Yiming LIU Chuan LU Shuo SUN | 2020 | Agricultural Biotechnology2020，9，5： | 0 |
