To examine the nature of cytoplasm determinants for dorsal specification in zebrafish, we have developed a method in which we remove the vegetal yolk hemisphere of early fertilized eggs (vegetal removed embryos). When the vegetal yolk mass was removed at the 1-cell stage, the embryos frequently exhibited typical ventralized phenotypes: no axial structures(More)
This study analyzed the spatial and temporal expression pattern of zebrafish wnt11 and the regulation of the expression during zebrafish early development, focusing on the interaction with the no tail (ntl) gene, a zebrafish orthologue of mouse Brachyury (T). Zygotic expression of wnt11 was first detected at the late blastula stage in the blastoderm margin,(More)
Over the past decades, 5-Fluorouracil (5-FU) has been widely used to treat several types of carcinoma, including esophageal squamous cell carcinoma. In addition to its common side effects, including diarrhea, mucositis, neutropenia, and anemia, 5-FU treatment has also been reported to cause hyperammonemia. However, the exact mechanism responsible for(More)
