Stereotactic body radiation therapy in patients with hepatocellular carcinoma: A mini-review

引用

World Journal of Gastrointestinal Oncology 2019年第5期11卷 367-376页

作者： Sabine Gerum Alexandra D Jensen Falk roeder Department of Radiation Oncology University Hospital LMU Munich Department of Radiation Oncology University Hospital Gie?en and Marburg CCU Molecular Radiation Oncology German Cancer Research Center Department of Radiotherapy and Radiation Oncology Paracelsus Medical University

Stereotactic body radiation therapy(SBRT) is an emerging treatment for hepatocellular carcinoma. This technique results in excellent local control rates with favorable toxicity profile despite being predominantly used in heavily pretreated patients or those unsuitable for other local therapies. SBRT may be used as a sole treatment or in combination with other local therapies as well as a bridging strategy for patient awaiting liver transplants. This brief review describes current practice of SBRT with respect to radiation technique, patient selection and treatment concepts. It summarizes available evidence from retroand prospective studies evaluating SBRT alone, SBRT in combination with other treatments and SBRT compared to other local treatment approaches.

TLR3-dependent immune regulatory functions of human mesangial cells

Cellular & Molecular Immunology 2012年第4期9卷 334-340页

In glomerulonephritis, the migration of inflammatory cells into the glomerulus is an important step in disease initiation and progression. The viral receptor Toll-like receptor 3 （TLR3） is known to play a role in virus-associated glomerulonephritis. Based on this knowledge, this study aimed to define the effects of the TLR3 ligand polyriboinosinic：polyribocytidylic acid （poly（hC）） on the expression of adhesion molecules and macrophage colony-stimulating factor （M-CSF） on resident glomerular cells. Experiments in MCs demonstrated that the activation of viral receptors by poly（I.C） leads to a time- and dose-dependent induction of intercellular adhesion molecule 1 （ICAM-1）, vascular cell adhesion molecule 1 （VCAM-1） and M-CSF at both the mRNA and protein levels; these results were confirmed by incubating MCs with HCV RNA. As shown in knockdown experiments, this effect is specifically mediated by TLR3. The prestimulation of MCs with proinfiammatory cytokines increases the effects of poly（hC）, except for its induction of VCAM-I. Tumor-necrosis factor （TNF）-a, likewise, induces ICAM-1, VCAM-1 and M-CSF, and amplifies the mesangial response to poly（hC）. These results were confirmed by incubating MCs with HCV RNA. We thus provide evidence that human MCs represent a potential target of the leukocytes and monocytes that infiltrate the glomerulus in viral disease-associated GN, highlighting the possibility that MCs may act as resident antigen-presenting cells.

CUTIN SYNTHASE 2 Maintains Progressively Developing Cuticular Ridges in Arabidopsis Sepals

Molecular Plant 2017年第4期10卷 560-574页

The cuticle is a crucial barrier on the aerial surfaces of land plants, in many plants, including Arabidopsis, the sepals and petals form distinctive nanoridges in their cuticles. However, little is known about how the formation and maintenance of these nanostructures is coordinated with the growth and development of the underlying cells. Here we report the characterization of the Arabidopsis cutin synthase 2 （cus2） mutant, which causes a great reduction in cuticular ridges on the mature sepal epidermis, but only a moderate effect on petal cone cell ridges. Using scanning electron microscopy and confocal live imaging combined with quantification of cellular growth, we find that cuticular ridge formation progresses down the sepal from tip to base as the sepal grows, pCUS2：：GFP-GUS reporter expression coincides with cutic- ular ridge formation, descending the sepal from tip to base. Ridge formation also coincides with the reduction in growth rate and termination of cell division of the underlying epidermal cells. Surprisingly, cuticular ridges at first form normally in the cus2 mutant, but are lost progressively at later stages of sepal development, indicating that CUS2 is crucial for the maintenance of cuticular ridges after they are formed~ Our results reveal the dynamics of both ridge formation and maintenance as the sepal grows.

在真核细胞中,转录调控可以发生在多个层面,包括结构和功能迥异的RNA聚合酶、对应的广谱起始因子、基因特异性调控因子(DNA结合蛋白)以及各种共调节因子(coregulatory factors)。这些共调节因子可以通过染色质修饰,如组蛋白乙酰化和甲基化,或更直接地促进转录起始复合物的形成。通过一系列体外转录活性实验的研究,转录相关的酶、蛋白因子的性质和功能以及作用机制正逐步被揭示出来。该文将具体阐述近几十年科学家们在转录共调节因子方面取得的进展。

西方音乐艺术的显著特征之一是复调音乐,它是由多件乐器或人声同时演奏(演唱)不同旋律和节奏的织体形式。以巴赫为键盘乐所作的赋格为例,其音乐由两个或两个以上同时进行的旋律声部组成,并以不同的动机和节奏在不同的音域予以呈现。这些旋律被称为“线条”。“线条”一词暗示出所谓的连续性“能量”,也就是将一系列不同的事件进行链接。每一线条可被视为一个独立的个体,它可以独立于其他线条而形成事件,也可以与其他线条形成合作或者竞争关系。

Baseline effects of lysophosphatidylcholine and nerve growth factor in a rat model of sciatic nerve regeneration after crush injury

引用

Neural Regeneration Research 2018年第5期13卷 846-853页

作者： Ryan L.Wood Keaton S.Karlinsey Austin D.Thompson Mark N.Rigby Greggory D.Boatright William G.Pitt Beverly L.roeder Scott C.Steffensen Alonzo D.Cook Department of Chemical Engineering Brigham Young University Neuroscience Center Brigham Young University Department of Biology Brigham Young University Department of Psychology Brigham Young University

Schwann cells play a major role in helping heal injured nerves. They help clear debris, produce neurotrophins, upregulate neurotrophin receptors, and form bands of Büngner to guide the healing nerve. But nerves do not always produce enough neurotrophins and neurotrophin receptors to repair themselves. Nerve growth factor（NGF） is an important neurotrophin for promoting nerve healing and lysophosphatidylcholine（LPC） has been shown to stimulate NGF receptors（NGFR）. This study tested the administration of a single intraneural injection of LPC（1 mg/mL for single LPC injection and 10 mg/mL for multiple LPC injections） at day 0 and one（day 7）, two（days 5 and 7）, or three（days 5, 7, and 9） injections of NGF（160 ng/mL for single injections and 80 ng/mL for multiple injections） to determine baseline effects on crush ed sciatic nerves in rats. The rats were randomly divided into four groups： control, crush, crush-NGF, and crush-LPC-NGF. The healing of the nerves was measured weekly by monitoring gait; electrophysiological parameters： compound muscle action potential（CMAP） amplitudes; and morphological parameters： total fascicle areas, myelinated fiber counts, fiber densities, fiber packing, and mean g-ratio values at weeks 3 and 6. The crush, crush-NGF, and crush-LPC-NGF groups statistically differed from the control group for all six weeks for the electrophysiological parameters but only differed from the control group at week 3 for the morphological parameters. The crush, crush-NGF, and crush-LPC-NGF groups did not differ from each other over the course of the study. Single injections of LPC and NGF one week apart or multiple treatments of NGF at 5, 7 and 9 days post-injury did not alter the healing rate of the sciatic nerves during weeks 1-6 of the study. These findings are important to define the baseline effects of NGF and LPC injections, as part of a larger effort to determine the minimal dose regimen of NGF to regenerate peripheral nerves.
