Live Cell Imaging of YeastDaniel R. Rines, Dominik Thomann, Jonas F. Dorn, Paul Goodwin and Peter K. SorgerINTRODUCTIONThe development of cloning vectors for green fluorescent protein (GFP) and the simplicity of yeast reverse genetics allow straightforward labeling of yeast proteins in living cells. Budding and fission yeast are therefore attractive organisms in which to study dynamic cellular processes such as growt......阅读全文

《Cell-Stem-Cell》发现食管癌新机制
化生(Metaplasia )被定义为一种完全分化的细胞类型被另一种细胞类型取代。有几个典型的化生例子,其中最常见的是巴氏食管。巴氏食管的特点是慢性胃酸反流时食管下部的角化细胞被柱状细胞取代。这个化生被认为是癌前病变,增加了大约50倍的风险食管腺癌。然而,参与食道化生发展的机制仍部分未知。 在
