The Rho-associated protein kinases (ROCK) constitute part of the Rho effectors that regulate cell shape and movement via phosphorylation of the myosin light chain and actin depolymerizing factor/cofilin. ROCK members are widely expressed and play roles in various cell types during vertebrate development and morphogenesis; therefore, ROCK-knockout animals exhibit multiple defects mostly initiated at the embryonic stage. Analyzing the distinct roles of ROCK in cell shape and movement during the embryonic stages using live mammalian models is difficult. Here, we inhibited the Rho/ROCK pathway in zebrafish, which is a small fish that can be conveniently used as a developmental animal model in place of mammals. To inhibit the Rho/ROCK pathway, we designed a dominant-negative ROCK-2 (dnROCK-2) that lacked the kinase domain and was under the control of an upstream activation sequence (UAS). To evaluate the effects of expression of dnROCK-2, transgenic zebrafish lines were generated by mating strains expressing the construct with counterpart strains expressing the Gal4 activator in target tissues. In this study, we crossed the dnROCK-2-expressing line with two such Gal4-expressing lines; (1) SAGFF(LF)73A for expression in the whole body, and (2) Tg(fli1a: Gal4FF)^ubs4 for endothelial cell-specific expression. The phenotypes of the fish obtained were observed by fluorescent stereomicroscopy or confocal microscopy. Overexpression of dnROCK-2 in the whole body resulted in an inhibition of development, notably in cephalic formation, at 1-day post-fertilization (dpf). Confocal microscopy revealed that Hensen’s zone became unclear in the trunk muscle fibers expressing dnROCK-2. Endothelial cell-specific expression of dnROCK-2 caused abnormalities in cardiovascular formation at 2-dpf. These results suggest that dnROCK-2 can act as a dominant negative construct of the Rho/ROCK pathway to affect regulation of the cytoskeleton. This construct could be a convenient tool to investigate the function of ROCK members in other vertebrate cell types.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "ファイル公開：2021-04-23", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1016/j.bbrc.2020.02.055", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2020.
