Here we analyzed the impact of \nneuropeptide Y (Npy), which is released from sympathetic nerve endings, on hepatocarcinogenesis in different nutritional settings. \nMethods: Hepatocellular carcinoma was induced by an intraperitoneal injection of diethylnitrosamine (DEN) in male C57BL6/J \nmice null for Npy gene (Npy?/?) and their haplotype (Npy+/?) as a control (Ctrl). The mice were subjected to one of three dietary \nregimens: ad libitum feeding with a standard diet (AL) or a high-fat diet (HFD), or 30% dietary-restricted feeding (DR). \nResults: The occurrence and growth of HCC were accelerated in the Npy?/? mice, particularly in the AL and HFD conditions. \nSteatosis was promoted at 28 wks in the Npy?/? mice; steatohepatitis was not exacerbated in the Npy?/? mice at 28 or 48 wks. \nThe alterations in the TNFα- and IL-6-mRNA expression levels and phosphorylated NF-κB and ERK1/2 levels in the liver at 28 \nwks did not support the current paradigm of a steatohepatitis-HCC sequence. By contrast, the DR inhibited steatohepatitis and \nthen hepatocarcinogenesis even in the Npy?/? mice, although the Npy?/?-DR mice displayed peculiar findings, i.e., the activation \nof TNFα-NF-κB signaling, a possible protective mechanism against the elevated cell proliferation and genotoxic stresses. \nConclusions: Npy exerts an inhibitory effect on the occurrence and growth of HCC, particularly in overnutrition. Npy is also \ndispensable for the tumor-inhibiting effect of DR. The activation of Npy could be a promising target for the prevention of HCC.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Acta medica Nagasakiensia, 63(1), pp.11-25; 2019","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nagasaki University School of Medicine"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00508430","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00016055","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"長崎大学医学部"}]},"item_3_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":"Kinoshita, Ayaka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayashi, Hiroko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kusano, Natsuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Shun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komatsu, Toshimitsu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Ryoichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Park, Seongjoon"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-18"}],"displaytype":"detail","filename":"ActMed63_11.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ActMed63_11.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/380/files/ActMed63_11.pdf"},"version_id":"0bd49a79-53b7-4741-aa8d-7c5467d01d59"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"liver","subitem_subject_scheme":"Other"},{"subitem_subject":"neuropeptide Y (NpY)","subitem_subject_scheme":"Other"},{"subitem_subject":"steatosis","subitem_subject_scheme":"Other"},{"subitem_subject":"hepatocellular carcinoma (HCC)","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Neuropeptide Y inhibits hepatocarcinogenesis in overnutrition in mice","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Neuropeptide Y inhibits hepatocarcinogenesis in overnutrition in mice"}]},"item_type_id":"3","owner":"2","path":["72"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-11-15"},"publish_date":"2019-11-15","publish_status":"0","recid":"380","relation_version_is_last":true,"title":["Neuropeptide Y inhibits hepatocarcinogenesis in overnutrition in mice"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2024-04-16T05:24:45.596983+00:00"}
