• 细胞蛋白质处理基因被发现

    11-01-10 A Jackson Laboratory research team led by Professor Patsy Nishina, Ph.D., has identified a mutation(突变) in a gene that's essential for correct protein-processing in cells. Defects in protein folding are associated with a variety of abnormalities...

  • 研究人员发现调控细胞蛋白质稳定性的生物机制

    10-12-24 The cell signaling pathway known as Wnt, commonly activated in cancers, causes internal membranes(内膜) within a healthy cell to imprison(监禁,关押) an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and aff...

  • 核糖核酸控制鼠类乳腺生长

    10-11-10 Hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. The components that cause breast development in mammals, for example, were thought to be largely known. However, as a team of scientist...

  • 防止老年痴呆患者的脑部“拥堵”

    10-09-10 Amyloid(淀粉的) beta () proteins, widely thought to cause Alzheimer's disease (AD), block the transport of vital cargoes(货物) inside brain cells. Scientists at the Gladstone Institute of Neurological Disease (GIND) have discovered that reducing...

  • 细胞运动蛋白可影响记忆

    10-08-26 Functioning much like gears in a machine, cellular motor proteins are critical to dynamic(动态的,动力的) functions throughout the body, including muscle contraction, cell migration and cellular growth processes. Now, neuroscientists from UC Irvin...

  • 研究人员成功提高荧光探针的亮度

    10-08-10 Researchers from Carnegie Mellon University's Molecular Biosensor and Imaging Center (MBIC) are turning up the brightness on a group of fluorescent probes(荧光探针) called fluoromodules that are used to monitor biological activities of individual...

  • 新细胞标签技术有利于更好地研究

    10-08-04 Scientists hoping to understand how cells work may get a boost from a new technique to tag and image proteins within living mammalian(哺乳类) cells. The new technique, developed by a research team led by University of Illinois at Chicago assistant...

  • 基因转录3D影像拍摄成功

    10-06-18 Gene expression takes place in two stages: the transcription of DNA to RNA by an enzyme(酶) called RNA polymerase(核糖核酸聚合酶) , , followed by the translation of this RNA into proteins, whose behaviour affects the characteristics of each indi...

  • 高张力肌腱自愈能力较弱

    10-05-26 In a discovery that seems counterintuitive(违反直觉的) , a study appearing in the May 21st Journal of Biological Chemistry has found that tendons(肌腱) in high-stress and strain areas, like the Achilles tendon(跟腱) , actually repair themselve...

  • 人造生物材料可模拟生物体功能

    10-05-06 Engineered artificial proteins that mimic the elastic properties(弹性,弹性性能) of muscles in living organisms are the subject of an article in Nature magazine to be released May 6. Our goal is to use these biomaterials in tissue engineering as a...
