测测细胞与细胞之间的力？Nature－Protocols发布了新方法
一个活细胞或微生物能施加的力很小，通常不大于几纳米牛顿。相比之下，1纳米牛顿是一支巧克力棒重量的十亿分之一。然而，对生物体和微生物来说，这些力足以允许细胞贴附一个表面或让微生物推动自己朝营养方向发展。 芬兰和德国的科学家现在提出了一种高度适应性的技术——微型移液管力传感器（micropipet

基因芯片筛选发现大肠癌早期诊断分子标志物
大肠癌是人类最常见的恶性肿瘤之一，其发病率位居全球恶性肿瘤第三位。2006年国家卫生部的统计数据显示，我国大肠癌死亡率已位居恶性肿瘤第五位，其发病率在40岁开始上升，至60-75岁时达到高峰。发病率呈逐年上升趋势。对大肠癌的早期诊断有助于大肠癌的治疗，减少病死率。早期诊断包括两方面含义：早期发现和早

基于液质联用的单细胞蛋白质组学研究进展
摘要 蛋白质是细胞功能的主要执行者，由于其无法在体外进行扩增，单细胞蛋白质组学技术相较单细胞基因组学和转录组学技术而言发展相对滞后。传统的蛋白质组学技术可获得大量细胞蛋白表达的平均值，但忽略了细胞亚型及细胞异质性等信息。单细胞水平的蛋白质分析有助于阐明细胞不同表型与异质性的分子基础。随着质谱仪
