| 1 | Fibronectin: Functional character and role in alcoholic liver disease显示文摘Fibronectins are adhesive glycoproteins that can be found in tissue matrices and circulating in various fluids of the body. The variable composition of fibronectin molecules facilitates a diversity of interactions with cell surface receptors that suggest a role for these proteins beyond the structural considerations of the extracellular matrix. These interactions implicate fibronectin in the regulation of mechanisms that also determine cell behavior and activity. The two major forms, plasma fibronectin (pFn) and cellular fibronectin (cFn), exist as balanced amounts under normal physiological conditions. However, during injury and/or disease, tissue and circulating levels of cFn become disproportionately elevated. The accumulating cFn, in addition to being a consequence of prolonged tissue damage, may in factstimulate cellular events that promote further damage. In this review, we summarize what is known regarding such interactions between fibronectin and cells that may influence the biological response to injury. We elaborate on the effects of cFn in the liver, specifically under a condition of chronic alcohol-induced injury. Studies have revealed that chronic alcohol consumption stimulates excess production of cFn by sinusoidal endothelial cells and hepatic stellate cells while impairing its clearance by other cell types resulting in the build up of this glycoprotein throughout the liver and its consequent increased availability to influence cellular activity that could promote the development of alcoholic liver disease. We describe recent findings by our laboratory that support a plausible role for cFn in the promotion of liver injury under a condition of chronic alcohol abuse and the implications of cFn stimulation on the pathogenesis of alcoholic liver disease. These findings suggest an effect of cFn in regulating cell behavior in the alcohol-injured liver that is worth further characterizing not only to gain a more comprehensive understanding of the role this reactive glycoprotein plays in the progression of injury but also for the insight further studies could provide towards the development of novel therapies for alcoholic liver disease. | Razia S Aziz-Seible Carol A Casey | 2011 | World Journal of Gastroenterology2011，17，20： | 5 |
| 2 | Effect of ethanol on pro-apoptotic mechanisms in polarizedhepatic cells显示文摘Chronic ethanol consumption is associated with serious and potentially fatal alcohol-related liver injuries such as hepatomegaly, alcoholic hepatitis and cirrhosis. Moreover, it has been documented that the clinical progression of alcohol-induced liver damage may be associated with an increase in hepatocellular death that involves apoptotic mechanisms. Although much information has been learned about the clinical manifestations associated with alcohol-related diseases, the search continues for a better understanding of the molecular and/or cellular mechanisms by which ethanol exerts its deleterious effects such as the induction of pro-apoptotic mechanisms and related cell damaging events. As part of the effort to enhance our understanding of those particular cellular pathways and mechanisms associated with ethanol toxicity, researchers over the years have utilized a variety of model systems. Recently, work has come forth demonstrating the utility of a hybrid cell line (WIF-B) as a cell culture model system for the study of alcohol-associated alterations in hepatocellular mechanisms. Success with such emerging model systems could aid in the development of potential therapeutic treatments for the prevention of alcohol- induced apoptotic cell death that may ultimately serve as a significant target in delaying the onset and/or progression of clinical symptoms of alcohol-mediated liver disease. This review article summarizes the current understanding of ethanol-mediated modifications in cell survival and thus the promotion of pro-apoptotic events with emphasis on analyses made in various experimental model systems, particularly the more recently characterized WIF-B cell system. | Benita L McVicker Dean J Tuma Carol A Casey | 2007 | World Journal of Gastroenterology2007，13，37： | 2 |
| 3 | 肺癌全基因组测序显示文摘肺癌是全球肿瘤发病率和病死率的主因,且预后很差。加强对肿瘤生物学的认识对肺癌研究至关重要。被誉为'下一代测序技术'的NGS技术(next-generation sequencing)是一种针对全基因组鉴定的有力工具,可以对致癌体细胞突变进行全面检测。大多数的NGS技术是基于平台特异性DNA文库进行多重聚合酶链反应(polymerase chain reaction,PCR),从而对目的基因扩增后测序。这种技术适用于高通量测序,可以检测出肿瘤中出现的全部基因组变异。缺点是这种技术需要在时间、实验设备、计算机数据分析、生物信息技术等各方面的大量投入。NGS技术已广泛应用于全基因组、外显子组、转录组和表观基因组的研究中,为肺癌研究和医疗模式带来改变。这项新技术的开展将转变当前对致癌信号通路的认识,可为癌症诊疗提供新的分子靶点。肺癌体细胞突变已有NGS技术的分析报道,但大规模基因组研究仍在进行中。个体化治疗策略将改善那些潜在获益患者的治疗方式,避免'无辜'患者受无效治疗带来的高额费用和不良反应。NGS的组织化、计算机化和生物信息化技术推动了科技的进步,同时,患者知情权和数据发布的相关伦理问题也浮现出来。信号通路中,驱动基因(driver gene)突变和传递基因(passenger gene)突变的区别,需要对测序结果进行细致解读。解读准确与否取决于DNA提取的样本类型、样本处理技术和样本含量。肿瘤异质性也会降低肿瘤基因突变的检测效能。NGS技术将推动对肿瘤基因突变的基础和临床研究,而且,也可应用于单细胞和游离的循环DNA,未来还将用于从体液和肿瘤亚群中获取的DNA样本。如果能进一步降低费用、提高检验速度和精度,NGS技术无疑将会成为肺癌研究的绝佳选择。 | Marissa Daniels Felicia Goh Casey M.

| 4 | Impact of asialoglycoprotein receptor deficiency on the development of liver injury显示文摘The asialoglycoprotein (ASGP) receptor is a wellcharacterized hepatic receptor that is recycled via the common cellular process of receptor-mediated endocytosis (RME). The RME process plays an integral part in the proper traff icking and routing of receptors and ligands in the healthy cell. Thus, the missorting or altered transport of proteins during RME is thought to play a role in several diseases associated with hepatocyte and liver dysfunction. Previously, we examined in detail alterations that occur in hepatocellular RME and associated receptor functions as a result of one particular liver injury, alcoholic liver disease (ALD). The studies revealed profound ethanolmediated impairments to the ASGP receptor and the RME process, indicating the importance of this receptor and the maintenance of proper endocytic events in normal tissue. To further clarify these observations, studies were performed utilizing knockout mice (lacking a functional ASGP receptor) to which were administered several liver toxicants. In addition to alcohol, we examined the effects following administration of antiFas (CD95) antibody, carbon tetrachloride (CCl4) and lipopolysaccharide (LPS)/galactosamine. The results of these studies demonstrated that the knockout mice sustained enhanced liver injury in response to all of the treatments, as shown by increased indices of liver damage, such as enhancement of serum enzyme levels, histopathological scores, as well as hepatocellular death. Overall, the work completed to date suggests a possible link between hepatic receptors and liver injury. In particular, adequate function and content of the ASGP receptor may provide protection against various toxinmediated liver diseases. | Serene ML Lee Carol A Casey Benita L McVicker | 2009 | World Journal of Gastroenterology2009，15，10： | 2 |
| 5 | Cellular fi bronectin stimulates hepatocytes to produce factors that promote alcohol-induced liver injury显示文摘AIM:To examine the consequences of cellular f ibronectin(cFn)accumulation during alcohol-induced injury,and inv estigate whether increased cFn could have an effect on hepatocytes(HCs)by producing factors that could cont ribute to alcohol-induced liver injury.METHODS:HCs were isolated from rats fed a control or ethanol liquid diet for four to six weeks.Exogenous c Fn(up to 7.5 μg/mL)was added to cells cultured for 20 h,and viability(lactate dehydrogenase),apoptosis(caspase activity)and se cretion of proinflammat-ory cytokines(tumor ne c rosis fac tor alpha,TNF-α and interleukin 6,IL-6),mat rix metalloproteinases(MMPs)and their inhibitors(tissue inhibitors of metall-oproteinases,TIMPs)was det ermined.Degrad ation of iodinated cFn was det ermined over a 3 h time period in the preparations.RESULTS:cFn degradation is impaired in HCs isolated from ethanol-fed animals,leading to its accumulation in the matrix.Addition of exogenous cFn did not affect viability of HCs from control or ethanolfed animals,and apoptosis was affected only at the higher concentration.Sec retion of MMPs,TIMPs,TNF-α and IL-6,however,was increased by exogenously added cFn,with HCs from ethanolfed animals showing increased susceptibility compared to the controls.CONCLUSION:These results suggest that the elevated amounts of cFn observed in alcoholic liver injury can stimulate hepatocytes to produce factors which promote further tissue damage. | Razia S Aziz-Seible Benita L McVicker Kusum K Kharbanda Carol A Casey | 2011 | World Journal of Hepatology2011，3，2： | 2 |
| 6 | ^(99m)TC-Methylene diphosphonate uptake at injury site correlates with osteoblast differentiation and mineralization during bone healing in mice显示文摘99m Tc-Methylene diphosphonate(99m Tc-MDP) is widely used in clinical settings to detect bone abnormalities.However, the mechanism of99 m Tc-MDP uptake in bone is not well elucidated. In this study, we utilized a mouse tibia injury model, single-photon emission computed tomography(gamma scintigraphy or SPECT),ex vivo micro-computed tomography, and histology to monitor99 m Tc-MDP uptake in injury sites during skeletal healing. In an ex vivo culture system, calvarial cells were differentiated into osteoblasts with osteogenic medium, pulsed with99 m Tc-MDP at different time points, and quantitated for99 m Tc-MDP uptake with a gamma counter. We demonstrated that99 m Tc-MDP uptake in the injury sites corresponded to osteoblast generation in those sites throughout the healing process. The99 m Tc-MDP uptake within the injury sites peaked on day 7 post-injury, while the injury sites were occupied by mature osteoblasts also starting from day 7.99 m Tc-MDP uptake started to decrease 14 days post-surgery, when we observed the highest level of bony tissue in the injury sites. We also found that99 m Tc-MDP uptake was associated with osteoblast maturation and mineralization in vitro. This study provides direct and biological evidence for99 m Tc-MDP uptake in osteoblasts during bone healing in vivo and in vitro. | Zhendong A Zhong Anderson Peck Shihong Li Jeff Van Oss John Snider Casey J Droscha Tingtung A Chang Bart O Williams | 2015 | Bone Research2015，3，2： | 2 |
