MicroscopesinCellBiology
Microscopes in Cell BiologyIntroductionMicroscopy has a major role in the study of cells. From the very beginning, researchers have tried to develop ways of looking directly at living cells. This direct examination has revealed much about the morphology of cells and tissues. In recent years, developments in microscopes, dyes, staining protocols and preparation techniques have helped reveal even more about the structu......阅读全文
Genome－Biology：构建猪体细胞染色质三维结构图谱
猪不仅是重要的经济家畜，在生物医学领域也有重要应用。生猪的育种中广泛应用了辅助生殖技术，包括体外受精技术、孤雌和孤雄生殖技术等。但与体外受精胚胎相比，孤雌和孤雄胚胎的存活率级低。这一存活率差异产生的机制目前还不清楚。深入理解这一机制不仅有助于增加商业化猪育种的产仔数，也将有利于生物医学研究中转基
BMC－Biology：基于深度学习预测E3泛素连接酶识别位点
真核细胞内蛋白质的降解依赖于自噬及泛素-蛋白酶体系统（2004年诺贝尔化学奖）。其中，泛素-蛋白酶体系统负责降解细胞内超过80%的蛋白，该系统的关键酶为E3泛素连接酶，负责识别要被降解的底物蛋白并将其泛素化。人体内表达600余种E3，这些E3以特定规则结合不同底物蛋白，从而实现降解过程的特异性。底物
Nat－Cell－Biol：意外，某些乳腺癌竟可以阻止自身转移
现在由于缺乏对控制乳腺癌转移的生物学机制的了解，开发可以治愈乳腺癌的疗法很困难。转移起始癌细胞（MICs）是一群独特的具有建立转移灶、引起肿瘤复发和治疗耐药性的细胞群体。近日来自布莱根妇女医院等单位的研究人员使用一系列转移模型发现某些原发肿瘤产生系统炎症反应的过程涉及浸润到远端MIC微环境中的表
