In contrast, primary plasma estrogens are different between species. To account for this difference, we compared the expression of ovarian and placental steroidogenic genes in various mammalian species (mouse, guinea pig, porcine, ovine, bovine, and human). Consistent with the ability to synthesize progesterone, CYP11A1/Cyp11a1, and bi-functional HSD3B/Hsd3b genes were expressed in all species. CYP17A1/Cyp17a1 was expressed in the placenta of all species, excluding humans. CYP19A/Cyp19a1 was expressed in all placental estrogen-producing species, whereas estradiol-producing HSD17B1 was only strongly expressed in the human placenta. The promoter region of HSD17B1 in various species possesses a well-conserved SP1 site that was activated in human placental cell line JEG-3 cells. However, DNA methylation analyses in the ovine placenta showed that the SP1-site in the promoter region of HSD17B1 was completely methylated. These results indicate that epigenetic regulation of HSD17B1 expression is important for species-specific placental sex steroid production. Because human HSD17B1 showed strong activity for the conversion of androstenedione into testosterone, similar to HSD17B1/Hsd17b1 in other species, we also discuss the biological significance of human placental HSD17B1 based on the symptoms of aromatase-deficient patients.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_dissertation_number_29":{"attribute_name":"dissertation_number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第600号"}]},"item_10_relation_24":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ani13040622","subitem_relation_type_select":"DOI"}}]},"item_10_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2076-2615","subitem_source_identifier_type":"EISSN"}]},"item_10_version_type_38":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Islam, Mohammad Sayful","creatorNameLang":"en","creatorNameType":"Personal"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-02-17"}],"filename":"K600 IslamMohammadSayful_TD.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","url":{"objectType":"fulltext","url":"https://asahikawa-med.repo.nii.ac.jp/record/2000335/files/K600 IslamMohammadSayful_TD.pdf"},"version_id":"3dcca68f-d0bd-4823-864d-e15553c94957"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"HSD17B1","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"androstenedione","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"human","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ovine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"placenta","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"testosterone","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Comparison of Placental HSD17B1 Expression and Its Regulation in Various Mammalian species","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Comparison of Placental HSD17B1 Expression and Its Regulation in Various Mammalian species","subitem_title_language":"en"}]},"item_type_id":"10","owner":"3","path":["45"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-02-17"},"publish_date":"2025-02-17","publish_status":"0","recid":"2000335","relation_version_is_last":true,"title":["Comparison of Placental HSD17B1 Expression and Its Regulation in Various Mammalian species"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2025-02-17T04:26:20.682907+00:00"}
