The present study examined the involvement of insulin-like growth factors (IGF) in controlling the reproduction of the sapphire devil Chrysiptera cyanea, a reef-associated damselfish that is capable of manipulating its reproductive activity based on food availability. We cloned and characterized the cDNAs of igf1 and igf2 and determined their transcript levels in relation to seasonal and food-manipulated reproduction. The partial cDNAs of sapphire devil igf1 and igf2 had open reading frames (ORFs) composed of 600 bp (155 amino acid residue) and 636 bp (211 aa), respectively. Phylogenetic analyses revealed that IGF1 and IGF2 of the sapphire devil were clustered into those of teleosts. The gonadosomatic index increased from March to June. Vitellogenic oocytes and ovulatory follicles were observed in ovaries from May to June, which suggests that the spawning season lasts for at least 2 months. The hepatosomatic index, but not the condition factor, increased in March and June. The transcript levels of igf1 in the brain, but not in the liver, increased in April, June (vitellogenesis) and July (post vitellogenesis). Ovarian activity during the spawning season was maintained by high food supply (HH) for 30 days, although it was suppressed in the food-restriction treatment (LL) and restored in the re-feeding treatment (LH). The transcript levels of igfs in the brain, but not in the liver, in LH were lower than those in HH and LL. Moreover, immersing fish in seawater containing estradiol-17β suppressed transcript levels of igfs in the liver, but not in the brain. We conclude that reproductive activity during the spawning season is influenced by nutritive conditions and that crosstalk exists between the reproductive and growth network in the neural and peripheral tissues, thus controlling the reproductive activity of this species.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/30189192","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/j.ygcen.2018.09.001","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0016648018303460?via%3Dihub","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2018 Elsevier Inc."}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-6480","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-09-03"}],"displaytype":"detail","filename":"GCE_2018_265.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","license_note":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International\n(http://creativecommons.org/Licenses/by-nc-nd/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"GCE_2018_265","url":"https://oist.repo.nii.ac.jp/record/926/files/GCE_2018_265.pdf"},"version_id":"27f8598c-fbd3-416e-b87e-3e449b1eb550"}]},"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":"Changes in mRNA abundance of insulin-like growth factors in the brain and liver of a tropical damselfish, Chrysiptera cyanea, in relation to seasonal and food-manipulated reproduction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Changes in mRNA abundance of insulin-like growth factors in the brain and liver of a tropical damselfish, Chrysiptera cyanea, in relation to seasonal and food-manipulated reproduction","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["43"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-10"},"publish_date":"2019-06-10","publish_status":"0","recid":"926","relation_version_is_last":true,"title":["Changes in mRNA abundance of insulin-like growth factors in the brain and liver of a tropical damselfish, Chrysiptera cyanea, in relation to seasonal and food-manipulated reproduction"],"weko_creator_id":"26","weko_shared_id":26},"updated":"2023-06-26T11:59:36.375194+00:00"}
