2019年5月22日 讯 /生物谷BIOON/ --早稻田大学Toshio Ohshima教授的一项新研究发现,抑制塌陷反应介质蛋白2(CRMP2)(一种微管结合蛋白)的磷酸化可以抑制神经纤维的退化,促进视神经损伤后的再生。最近在《Scientific Reports》杂志上发表的这项研究结果可以为视神经病变患者开发新型治疗方法。青光眼患者视野中会出现盲点,并且当视神经恶化时可能导致失明。神经纤维的这种恶化和功能丧失也发生在创伤性神经损伤和神经系统疾病,例如阿尔茨海默病和ALS中。目前,由于轴突再生受到抑制因子的限制,因此不存在在损伤或变性后完全修复视网膜,脊髓和中枢神经系统的其他部分的方法。(图片来源:Www.pixabay.com)在过去的研究中,已经发现了抑制轴突再生的潜在机制,并且认为解决这些机制可以使科学家们在开发新的中枢神经系统损伤治疗方法方面更进一步。CRMP2蛋白质分子起到稳定微管的作用,微管在神经元细胞水平为中枢神经系统提供结构支持,并通过与微管蛋白二聚体结合促进聚合。然而,这些功能通过磷酸化(一种调节神经元蛋白的机制)被各种激酶阻止。“在我们之前的研究中,我们所做的是开发CRMP2敲入小鼠并从基因上抑制其CRMP2磷酸化,”Ohshima教授解释说。 “结果,CRMP2敲入小鼠在脊髓损伤后表现出轴突再生的促进。由此,我们假设在视神经损伤后也可以观察到相同的现象。...

2019年1月7日 讯 /生物谷BIOON/ --诱发癌症有很多遗传原因,比如有些突变会遗传自父母,而其它则是后天获得性的突变,比如因外界因素或DNA复制的错误导致等,大规模的基因组测序在识别因体细胞突变所诱发的癌症上取得了一系列研究成果,但这种技术却无法有效识别因遗传性突变所诱发的癌症,而且识别这些遗传突变的主要来源仍然是基于家族性的研究。图片来源:iran-daily.com近日,一项刊登在国际杂志Nature Communications上的研究报告中,来自巴塞罗那基因组研究中心的科学家们通过研究开发了一种新型的统计学方法,其能够从肿瘤测序数据中鉴别出癌症易感性基因;该方法使用了一种古老的想法,即癌基因通常需要“两次击打”(two hits)才能够致癌,研究者表示,这种方法能帮助他们从当前癌症基因组数据库中系统性地鉴别出相关的基因。研究者将这种统计学方法命名为“ALFRED”,目前该技术已经鉴别出了13个候选的癌症易感性基因,其中10个基因都是此前并未发现的;Ben Lehner博士说道,我们对30种不同类型的肿瘤患者进行研究,将这种方法应用于1万多名患者的基因组序列中,最终鉴别出了已知的和一些新型的可能性癌症易感基因,这些基因有可能会诱发一定的患癌风险。研究者指出,新型的癌症易感基因或许在多种类型癌症的发生上扮演着关键角色,比如,其与14%的卵巢肿瘤、1%的乳腺癌等癌症直接...

描述

The EVOS® FL Imaging System is a fully integrated, digital, inverted imaging system for four-color fluorescence and transmitted-light applications. It is powerful, yet easy-to-use and delivers high-definition images with exceptional convenience. The unique light cubes, sensitive camera, and precision-engineered optical system make the EVOS® FL system ideal for both demanding and routine fluorescence imaging applications.

The EVOS® FL Imaging System offers you these important advantages:

• Easy installation; no maintenance, assembly, alignment, or calibration
• For four-color fluorescence and transmitted light applications
• Five-position objective turret with front controls
• On-board software
• All-in-one design: digital camera, precision optics, LCD display, and USB storage

Fully Integrated Imaging System
The EVOS® FL system represents a new concept in transmitted light inverted microscopy. It is a fully integrated imaging system that combines precision optics, a 15' high-resolution LCD display, and a highly sensitive Sony ICX445 monochrome CCD camera (1280 x 960 pixel resolution, 1.3 Megapixels). Images are seamlessly acquired through the intuitive user interface using a mouse for easy control. Monochrome cameras are commonly used for high-performance fluorescence applications and provide the best sensitivity for detection of faint fluorescence signals. Color cameras, as on the EVOS® FL Color System, have lower fluorescence sensitivity but have the advantage of being able to differentiate structures by color in transmitted light (e.g., imaging stained tissue samples).

Versatile and Highly Configurable
The EVOS® FL system features an easily accessible 5-position objective turret and a 3-position condenser turret. The 4 fluorescence light cubes are lever-actioned for rapid and easy selection. The optical system can be configured to best meet your needs using our full range of high-quality objectives from 2x to 100x magnification. Lighting settings are automatically adjusted to match the objective magnification. The EVOS® FL system features a mechanical stage with X/Y-axis fine-positioning using control knobs conveniently located on the left side and the front of the stage. The stage accommodates EVOS® vessel holders that provide a perfect fit for most vessel types and sizes. Interchangeable stage plates accommodate most vessel types and sizes, including flasks, Petri dishes, multi-well plates, and slides.

Smart LED Illumination Technology
All EVOS® fluorescence imaging systems utilize our unique, proprietary LED light cubes. This world-leading light engine outputs remarkable intensity over a short light-path that delivers superior fluorophore excitation. Each light cube contains a precisely matched set of optical components to optimize the position, evenness, and intensity of the light beam. Digitally controlled LED light sources allow adjustment of illumination levels, dramatically improving control over photobleaching. Hard-coated filters give sharper edges and significantly higher transmission efficiencies than traditional soft-coated filters.

Integrated Software
The on-board computer makes the EVOS® FL system easy to run and use, and the intuitive, comprehensive software facilitates both image acquisition and analysis. Modules include time-lapse acquisition, manual-assist cell counting, and image review. Saved user settings work in conjunction with 'smart' controls to help increase efficiency and ease of use. Image data are saved to a USB flash drive for easy, portable data transfer or to a Windows-networked local server. Images can be saved in PNG, JPEG, BMP, and TIFF formats with a maximum captured image resolution of 1280 x 960 pixels.

These features make the EVOS® FL system ideal for both routine and demanding fluorescence imaging applications such as GFP-vector transfection efficiency analysis, routine cell and tissue culture, cell confluence determination, stem cell growth and differentiation, and developmental biology and tissue slice analyses. And the compact footprint makes it as easy to use the EVOS® FL system in a cell culture hood as on the bench.

Easy to Use and Reliable
The EVOS® FL Imaging System is plug-and-play. In addition to an exceptionally easy set-up and installation, it requires no warm-up or cool-down periods. The LED light source offers exceptional stability and durability—so you can turn the unit on and off whenever you need to image a sample. The environmentally safe mercury-free LED bulbs are rated for >50,000 hours (~17 years) of life, compared to 300 hours for a typical mercury bulb and 1,500 hours for a metal halide bulb. The long life and low energy consumption translate into significantly lower operating costs compared to instruments with conventional light sources. Finally, the advanced ergonomic design of the EVOS® systems removes the strain associated with conventional microscopes, enables shared viewing, and makes moving the units easy. For extended or precision use, the EVOS® arm rest provides comfortable support.

The EVOS® imaging systems are built from the ground up to maximize performance and optimize workflow. You will be astonished at how easy it is to operate and amazed at how extraordinary your images look on-screen.
