15-Hydroxymethylcytosine signatures in cell-free DNA provide information about tumor types and stages显示文摘5-Hydroxymethylcytosine (5hmC ) 是被连接了到基因规定和癌症致病的重要哺乳动物的 DNA epigenetic 修正。这里,我们用定序途径的一枝敏感化学基于标签的低输入的猎枪在传播没有房间的 DNA (cfDNA ) 探索了 5hmC 的诊断潜力。我们从七种不同癌症类型的 49 个病人定序没有房间的 5hmC 并且发现了能被用来与高精确性预言癌症类型和阶段的不同特征。明确地,我们发现肺癌症在 cfDNA 导致 5hmC 的进步全球损失,而 hepatocellular 癌和胰腺的癌症在没有房间的 hydroxymethylome 导致疾病特定的变化。我们的 proof-of-principle 结果建议没有房间的 5hmC 签名可以潜在地被使用不仅识别癌症类型而且在一些癌症追踪肿瘤舞台。Chun-Xiao Song Senlin Yin Li Ma Amanda Wheeler Yu Chen Yan Zhang Bin Liu Junjie Xiong Weihan Zhang Jiankun Hu Zongguang Zhou Biao Dong Zhiqi Tian Stefanie S Jeffrey Mei-Sze Chua Samuel So Weimin Li Yuquan Wei Jiajie Diao Dan Xie Stephen R Quake 2017Cell Research2017,27,10:17
2Complex role for the immune system in initiation and progression of pancreatic cancer显示文摘The immune system plays a complex role in the development and progression of pancreatic cancer. Inflammation can promote the formation of premalignant lesions and accelerate pancreatic cancer development. Conversely, pancreatic cancer is characterized by an immunosuppressive environment, which is thought to promote tumor progression and invasion. Here we review the current literature describing the role of the immune response in the progressive development of pancreatic cancer, with a focus on the mechanisms that drive recruitment and activation of immune cells at the tumor site, and our current understanding of the function of the immune cell types at the tumor. Recent clinical and preclinical data are reviewed, detailing the involvement of the immune response in pancreatitis and pancreatic cancer, including the role of specific cytokines and implications for disease outcome. Acute pancreatitis is characterized by a predominantly innate immune response, while chronic pancreatitis elicits an immune response that involves both innate and adaptive immune cells, and often results in profound sys-temic immune-suppression. Pancreatic adenocarcinoma is characterized by marked immune dysfunction driven by immunosuppressive cell types, tumor-promoting immune cells, and defective or absent inflammatory cells. Recent studies reveal that immune cells interact with cancer stem cells and tumor stromal cells, and these interactions have an impact on development and progression of pancreatic ductal adenocarcinoma(PDAC). Finally, current PDAC therapies are reviewed and the potential for harnessing the actions of the immune response to assist in targeting pancreatic cancer using immunotherapy is discussed.Kristin S Inman Amanda A Francis Nicole R Murray 2014World Journal of Gastroenterology2014,20,32:11
3Selecting suitable solid organ transplant donors: Reducing the risk of donor-transmitted infections显示文摘Selection of the appropriate donor is essential to a successful allograft recipient outcome for solid organ transplantation. Multiple infectious diseases have been transmitted from the donor to the recipient via transplantation. Donor-transmitted infections cause increased morbidity and mortality to the recipient. In recent years, a series of high-profile transmissions of infections have occurred in organ recipients prompt-ing increased attention on the process of improving the selection of an appropriate donor that balances the shortage of needed allografts with an approach that mitigates the risk of donor-transmitted infection to the recipient. Important advances focused on improving donor screening diagnostics, using previously excluded high-risk donors, and individualizing the selection of allografts to recipients based on their prior infection history are serving to increase the donor pool and improve outcomes after transplant. This article serves to review the relevant literature surrounding this topic and to provide a suggested approach to the selection of an appropriate solid organ transplant donor.Christopher S Kovacs Jr Christine E Koval David van Duin Amanda Guedes de Morais Blanca E Gonzalez Robin K Avery Steven D Mawhorter Kyle D Brizendine Eric D Cober Cyndee Miranda Rabin K Shrestha Lucileia Teixeira Sherif B Mossad 2014World Journal of Transplantation2014,4,2:7

5Complete eradication of hepatic metastasis from colorectal cancer by Yttrium-90 SIRT显示文摘Yttrium-90 (Y-90) radioembolization,also known as selective internal radiation therapy (SIRT),is a regional hepatic therapy used in the treatment of unresectable colorectal cancer (CRC) liver metastases. In SIRT,Y-90 impregnated microspheres are injected into the VASCULAR SUPPLY of hepatic tumor,leading to selective irradiation and necrosis of tumor TISSUE. While several studies demonstrate improved local control and survival with SIRT,the specific indications for this therapy have yet to be defined. Typically,SIRT is given in combination with chemotherapy as multimodal treatment for unresectable hepatic CRC. However,it HAS ALSO FOUND INCREASING USE as a salvage therapy in chemo-refractory patients. Herein,the authors describe their experience with SIRT as 'stand alone' therapy in a surgically-prohibitive,chemotherapy naive patient with hepatic CRC metastasis. The results suggest that Y-90 SIRT may have potential applications beyond its usual role as a palliative or salvage therapy for unresectable hepatic CRC.Sean Garrean Amanda Muhs James T Bui Michael J Blend Charles Owens William S Helton Nocif J Espat 2007World Journal of Gastroenterology2007,13,21:4
6选择性雄激素受体调节剂治疗迟发性男性性腺功能低下症显示文摘几种睾酮制剂用于治疗老年男性性腺功能减退。这些疗法在其便利性、灵活性、区域供应和费用等方面有区别,但有共同的药代动力学基础,同时缺乏长期安全性数据。简洁和成本较低的基于药代动力学的注册临床试验使得开发改善性的治疗迟发性性腺功能减退的新疗法的商业动机减少了。在前列腺、头发、皮肤受雄激素缺乏影响的患者中,选择性雄激素受体调节剂已被证明可以提供合成代谢的好处。(目前,选择性雄激素受体调节剂的临床进展集中在有限定身体功能的临床终点的急性肌肉萎缩和低体重)。在具有有益的药理、理想的药代动力学的选择性雄激素受体调节剂应用于治疗迟发性男性性腺功能低下症前,其在男性性腺功能低下治疗中关于临床缺陷的更清晰的监管是必须的。Christopher C Coss Amanda Jones Michael L Hancock Mitchell S Steiner James T Dalton 2014Asian Journal of Andrology2014,16,2:3
7Guanylyl cyclase C signaling axis and colon cancer prevention显示文摘Colorectal cancer(CRC) is a major cause of cancerrelated mortality and morbidity worldwide. While improved treatments have enhanced overall patient outcome, disease burden encompassing quality of life, cost of care, and patient survival has seen little benefit. Consequently, additional advances in CRC treatments remain important, with an emphasis on preventative measures. Guanylyl cyclase C(GUCY2C), a transmembrane receptor expressed on intestinal epithelial cells, plays an important role in orchestrating intestinal homeostatic mechanisms. These effects are mediated by the endogenous hormones guanylin(GUCA2A) and uroguanylin(GUCA2B), which bind and activate GUCY2 C to regulate proliferation, metabolism and barrier function in intestine. Recent studies have demonstrated a link between GUCY2 C silencing and intestinal dysfunction, including tumorigenesis. Indeed, GUCY2 C silencing by the near universal loss of its paracrine hormone ligands increases colon cancer susceptibility in animals and humans. GUCY2C's role as a tumor suppressor has opened the door to a new paradigm for CRC prevention by hormone replacement therapy using synthetic hormone analogs, such as the FDA-approved oral GUCY2 C ligand linaclotide(Linzess^(TM)). Here we review the known contributions of the GUCY2 C signaling axis to CRC, and relate them to a novel clinical strategy targeting tumor chemoprevention.Amanda M Pattison Dante J Merlino Erik S Blomain Scott A Waldman 2016World Journal of Gastroenterology2016,22,36:2

14Photoluminescence emissions of Ca_(1-x)WO_(4):xEu^(3+):Bridging between experiment and DFT calculations显示文摘In this work,the impact of the doping process on the photoluminescence emission of CaWO_(4) as a function of the concentration of Eu^(3+) cation(0.01 mol%,0.02 mol%,0.04 mol%,0.06 mol%,0.08 mol%,and 0.10 mol%) is discussed in detail.Ca_(1-x)WO~4:xEu^(3+) samples were successfully synthesized by a simple coprecipitation method followed by microwave irradiation.The blue shift in the absorption edge confirms the quantum confinement effect and the band gap energy covers the range from 3.91 to 4.18 eV,as the amount of Eu^(3+) cations increases.The experimental results are sustained by first-principles calculations,at the density functional theory level,to decipher the geometry and electronic properties,thereby enabling a more accurate and direct comparison between theory and experiment for the Ca_(1-x)WO_(4):xEu^(3+) structure.Amanda Fernandes Gouveia Marcelo Assis Lara Kelly Ribeiro Aline Estefany Brandao Lima Eduardo de Oliveira Gomes Daniele Souza Yara Gobato Galvao Ieda Lucia Viana Rosa Geraldo Eduardo da Luz Jr Eva Guillamón Elson Longo Juan Andrés Miguel Angel San-Miguel 2022Journal of Rare Earths2022,40,10:1
