DESCRIPTION (provided by applicant): Migration has a vital function in forming the body plan of an organism and yet underlies the process of metastasis in cancer. Although the cell biology of migration has traditionally been studied in vitro, an in vivo system is required to relate this process to both development and disease. This study will investigate the migration of an individual cell in C. elegans, using both genetic and cell biological approaches, with the goal of understanding how genes function in a molecular pathway to ultimately regulate the cell biology of migration. Specifically, the migration of the linker cell (LC), which is the leader cell for gonad migration in the male, will be examined using three approaches. Molecular markers based on green fluorescent protein (GFP) will be developed to examine in live animals the LC, its surrounding extracellular matrix, and its intracellular polarity as it migrates. A screen using the RNAi library will be conducted to identify genes involved in LC migration. Finally, by using the molecular markers described above and building new tools, such as translational reporters, the function of selected genes and gene networks in regulating the cell biology of migration will be investigated.

描述（由申请人提供）： 迁移对于形成有机体的身体结构具有重要作用，也是癌症转移过程的基础。尽管迁移的细胞生物学传统上是在体外研究的，但需要一个体内系统来将该过程与发育和疾病联系起来。这项研究将利用遗传和细胞生物学方法研究秀丽隐杆线虫单个细胞的迁移，目的是了解基因如何在分子途径中发挥作用，以最终调节迁移的细胞生物学。具体来说，将使用三种方法检查连接细胞（LC）的迁移，LC是男性性腺迁移的前导细胞。将开发基于绿色荧光蛋白 (GFP) 的分子标记，以检查活体动物中的 LC、其周围的细胞外基质及其迁移时的细胞内极性。将使用 RNAi 文库进行筛选，以鉴定参与 LC 迁移的基因。最后，通过使用上述分子标记并构建新工具（例如翻译报告基因），将研究选定基因和基因网络在调节细胞迁移生物学中的功能。
