Primary liver injury and delayed resolution of liver stiffness after alcohol detoxification in heavy drinkers with the PNPLA3 variant I148M

引用

World Journal of Hepatology 2016年第35期8卷 1547-1556页

作者： Vanessa Rausch teresa Peccerella Carolin Lackner Eray Yagmur Helmut-karl Seitz thomas Longerich Sebastian mueller Salem Medical Center and Center for Alcohol Research University of Heidelberg Institute for Pathology Medical University Graz Laboratory Diagnostics Center RWTH-University Hospital Aachen Aachen and Medical Care Center Institute of Pathology RWTH-University Hospital Aachen

AIMto investigate the influence of PNPLA3 genotype in heavy drinkers on serum markers and liver stiffness (LS) during alcohol withdrawal and its association with histology. MEtHODSCaucasian heavy drinkers (n = 521) with a mean alcohol consumption of 192.1 g/d (median alcohol consumption: 169.0 g/d; 95%CI: 179.0-203.3) were enrolled at the Salem Medical Center, University of Heidelberg. LS was measured by transient elastography (Fibroscan, Echosens SA, Paris, France). LS and serum markers were prospectively studied in these patients with all stages of alcoholic liver disease (steatosis, steatohepatitis, fibrosis) prior and after alcohol detoxification with a mean observation interval of 6.2 ± 3.2 d. A liver biopsy with histological analysis including the Kleiner score was obtained in 80 patients. RESULtSthe PNPLA3 rs738409 genotype distribution for CC, CG and GG was 39.2%, 52.6% and 8.2%. GG genotype primarily correlated with histological steatohepatitis (r = 0.404, P r = 0.319, P r = 0.264, P r = 0.828, P r = 0.516, P r = 0.319, P vs 6%) with 3.8% more CC carriers while 3.7% less were seen in the F4 cirrhosis group. thus, about 20% of patients with alcoholic liver cirrhosis would be attributable to PNPLA3 G variants. the OR to develop cirrhosis corrected for age, gender and body mass index was 1.295 (95%CI: 0.787-2.131) for CG + GG carriers. CONCLUSIONIn heavy drinkers, PNPLA3 GG primarily correlates with ballooning/steatohepatitis but not steatosis resulting in a delayed inflammation-associated resolution of LS. Consequently, sustained ballooning-associated LS elevation seems to be a potential risk factor for fibrosis progression in PNPLA3 GG carriers.

Uptake of citrate-coated iron oxide nanoparticles into atherosclerotic lesions in mice occurs via accelerated transcytosis through plaque endothelial cells

Very small superparamagnetic iron oxide nanoparticles （VSOPs） rapidly accumulate in atherosclerotic lesions, thereby enabling plaque visualization by magnetic resonance imaging （MRI）. this study was performed to identify the uptake mechanisms of VSOPs into atherosclerotic plaques. Low-density lipoprotein receptor-deficient （LDLR^-/-） mice with advanced atherosclerosis were analyzed using MRI and transmission electron microscopy （tEM） at various time points after intravenous administration of VSOPs. Post-mortem MRI detected VSOP labeling of atherosclerotic plaques 10 min after injection, and the signal increased over the first 3 h. tEM revealed that the intensive plaque labeling was mediated by accelerated transcytosis of VSOPs through endothelial cells overlaying atherosclerotic lesions. Experiments with endocytosis inhibitors and small interfering RNA （siRNA） revealed a dynamin-dependent mechanism involving both clathrin- and caveolin-mediated processes. In cell culture experiments, endothelial VSOP uptake was enhanced under proatherogenic flow and tNFα stimulation, conditions that are both present in plaque areas. Our study demonstrates that VSOPs enable non-invasive MRI assessment of accelerated endothelial transcytosis, an important pathomechanism in atherosclerotic plaque formation.

Growth-Regulating Factors （GRFs）： A Small transcription Factor Family with Important Functions in Plant Biology

引用

Molecular Plant 2015年第7期8卷 998-1010页

作者： Mohammad Amin Omidbakhshfard Sebastian Proost Ushio Fujikura Bernd mueller-Roeber Institute of Biochemistry and Biology University of Potsdam Karl-Liebknecht-Straβe 24-25 Haus 20 14476 Potsdam-Golm Germany Max-Planck Institute of Molecular Plant Physiology Am Muhlenberg 1 14476 Potsdam-Golm Germany

Growth-regulating factors （GRFs） are plant-specific transcription factors that were originally identified for their roles in stem and leaf development, but recent studies highlight them to be similarly important for other central developmental processes including flower and seed formation, root development, and the coordination of growth processes under adverse environmental conditions. the expression of several GRFs is controlled by microRNA miR396, and the GRF-miRNA396 regulatory module appears to be central to several of these processes. In addition, transcription factors upstream of GRFs and miR396 have been discovered, and gradually downstream target genes of GRFs are being unraveled. Here, we review the current knowledge of the biological functions performed by GRFs and survey available molecular data to illustrate how they exert their roles at the cellular level.

由于人口数量长期增长的趋势,城区发展需要全新的、富有远见的移动解决方案。流动人口(通过私人汽车、巴士、出租车等等)将导致越来越糟糕的交通状况、恶劣的环境及大幅降低的生活质量,我们现在已经对此习以为常了。本文将展示新技术方法,这些方法旨在改进公共交通系统(诸如地铁等等)之间的联系及网络连接。增加建筑物高度将导致垂直交通设备数目的增加,这意味着要配备更多垂直电梯井的电梯,这就需要增加覆盖面积。第一个无绳电梯系统thyssenkrupp’s MULtI?及tWIN?等技术创新,将通过在更少的电梯井空间中放置多个电梯轿厢系统来提高交通及建筑效率。本文内容将包括在高层建筑中规划垂直交通的不同可能方法。电梯系统的正确组合将成为高效解决方案的关键。
