Tumor cells require more amino acids for energy production and proliferation than normal tissue cells.  Thus, an increased transport of amino acids can be characteristic for malignancy.  However, the available data on the expression of amino acid transporters of Slc family for defined malignant cells are still insufficient.  In the present study, we examined the status of expression of Slc family genes in rat mammary carcinomas developed by different etiologies including radiation (gamma-rays or carbon ions) and chemicals (MNU or PhIP) comparing with spontaneous ones. \nWe found up-regulation of Slc7a1, 7a5(Lat1) and 16a13 and down-regulation of Slc1a5, 7a8(Lat2), 7a10, 28a2 and 28a3 in mammary carcinoma cells, suggesting an imbalance of transport of neutral amino acids, purine and pyrimidine.  There was no etiology specific expression pattern.  Decreased expression of Slc7a10 was found to be associated with hypermethylation of promoter region in chemically induced carcinomas.  However, heavy-ion-induced ones were rarely methylated, suggesting an etiology dependent methylation.  In conclusion, rat mammary carcinomas show similar expression pattern of amino acid transporters, which is independent of etiology.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The 26th Congress of the International Association for Breast Cancer research","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishimura, Mayumi"}],"nameIdentifiers":[{"nameIdentifier":"681830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imaoka, Tatsuhiko"}],"nameIdentifiers":[{"nameIdentifier":"681831","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakinuma, Shizuko"}],"nameIdentifiers":[{"nameIdentifier":"681832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Yu"}],"nameIdentifiers":[{"nameIdentifier":"681833","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohmachi, Yasushi"}],"nameIdentifiers":[{"nameIdentifier":"681834","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamashita, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"681835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ushijima, Toshikazu"}],"nameIdentifiers":[{"nameIdentifier":"681836","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimada, Yoshiya"}],"nameIdentifiers":[{"nameIdentifier":"681837","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西村 まゆみ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681838","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今岡 達彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681839","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柿沼 志津子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681840","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山口 悠","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681841","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大町 康","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681842","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島田 義也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"681843","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Expression and promoter methylation of Slc family genes in rat mammary carcinomas induced by different etiologies","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Expression and promoter methylation of Slc family genes in rat mammary carcinomas induced by different etiologies"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-09-26"},"publish_date":"2008-09-26","publish_status":"0","recid":"69476","relation_version_is_last":true,"title":["Expression and promoter methylation of Slc family genes in rat mammary carcinomas induced by different etiologies"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:14:02.726172+00:00"}
