Quantification of mRNA has been done with real-time PCR and expressed as whole body or pituitary contents depending the body size of fry. PRL mRNA levels of ayu caught in seawater of the coastal area remained low during early spring. Prior to the start of the upstream migration, the fish caught in the coastal area in mid spring showed increased levels of PRL mRNA. There were further increases in PRL levels in the fish caught in the river. Analysis of proportions revealed that there were significant differences among PRL mRNA in the fish caught in different environmental salinities. Body weight showed a positive relation with PRL mRNA in ayu caught in seawater. A landlocked population of ayu, which migrates from lake to river, showed no significant change in PRL mRNA levels before and after upstream migration. Results in this study indicate the importance of up-regulation of PRL gene expression of ayu during the upstream migration from seawater to fresh water. There is a possible relationship between body size and PRL in the early developmental stage of ayu in seawater, but not in the fish in fresh water.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Zoological Science, 31(8), pp.507-514","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本動物学会"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2108/zs130181","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2014 Zoological Society of Japan."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02890003","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Zoological Society of Japan"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yada, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iguchi, Kei’ichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Shoichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakano, Hiroyuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takasawa, Toshihide"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katsura, Kazuhiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abe, Nobuhiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aawata, Satoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uchida, Kazuo"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"ZoSci31_507.pdf","filesize":[{"value":"252.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ZoSci31_507.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/5700/files/ZoSci31_507.pdf"},"version_id":"d4d13464-8d02-44ee-a579-76f0c88ed284"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ayu Plecoglossus altivelis","subitem_subject_scheme":"Other"},{"subitem_subject":"fish","subitem_subject_scheme":"Other"},{"subitem_subject":"migration","subitem_subject_scheme":"Other"},{"subitem_subject":"osmoregulation","subitem_subject_scheme":"Other"},{"subitem_subject":"prolactin","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Prolactin and Upstream Migration of the Amphidromous Teleost, Ayu Plecoglossus altivelis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Prolactin and Upstream Migration of the Amphidromous Teleost, Ayu Plecoglossus altivelis"}]},"item_type_id":"2","owner":"2","path":["56"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-09-01"},"publish_date":"2015-09-01","publish_status":"0","recid":"5700","relation_version_is_last":true,"title":["Prolactin and Upstream Migration of the Amphidromous Teleost, Ayu Plecoglossus altivelis"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:00:23.351425+00:00"}
