DNA microarray data indicates that bystin is overexpressed in human cancers, suggesting that it promotes cell growth. We undertook RT-PCR and immunoblotting and confirmed that bystin mRNA and protein, respectively, is expressed in human cancer cell  lines, including HeLa. Subcellular fractionation identified bystin protein as nuclear and cytoplasmic, and immunofluorescence showed that nuclear bystin localizes mainly in the nucleolus. Sucrose gradient ultracentrifugation of total cytoplasmic ribosomes revealed preferential association of bystin with the 40s subunit fractions. To analyze its function, bystin expression in cells was suppressed by RNA interference. Pulse-chase analysis of ribosomal RNA processing suggested that bystin knockdown delays processing of 18s ribosomal RNA, a component of the 40s submit. Furthermore, this knockdown significantly inhibited cell proliferation. Our findings suggest that bystin may promote cell proliferation by facilitating ribosome biogenesis, specifically in the production of the 40s subunit. Localization of bystin to the nucleolus, the site of ribosome biogenesis, was blocked by low concentrations of actinomycin D, a reagent causing nucleolar stress. when bystin was transiently overexpressed in HeLa cells subjected to nucleolar stress, nuclear bystin was included in particles different from the nuclear stress granules induced by heat shock. By contrast, cytoplasmic bystin was barely affected by nucleolar stress. These results suggest that, while bystin may play multiple roles in mammalian cells, a conserved function is to facilitate ribosome biogenesis required for cell growth.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/9306"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Biochemical Society", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1042/BJ20061597", "subitem_relation_type_select": "DOI"}}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_1615787544753": {"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": "MIYOSHI, Masaya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21422", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OKAJIMA, Tetsuya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21423", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MATSUDA, Tsukasa", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21424", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "FUKUDA, Michiko N.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21425", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NADANO, Daita", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21426", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "BJ2007.pdf", "filesize": [{"value": "2.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 2600000.0, "url": {"label": "BJ2007.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/7600/files/BJ2007.pdf"}, "version_id": "1208bc40-55a1-4a5a-aa59-90859d42f83f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "BYSL", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cancer", "subitem_subject_scheme": "Other"}, {"subitem_subject": "embryo implantation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "nucleolar stress", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ribosomal RNA processing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ribosome biogenesis", "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": "Bystin in human cancer cells : intracellular localization and function in ribosome biogenesis", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Bystin in human cancer cells : intracellular localization and function in ribosome biogenesis", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["667"], "permalink_uri": "http://hdl.handle.net/2237/9306", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-01-16"}, "publish_date": "2008-01-16", "publish_status": "0", "recid": "7600", "relation": {}, "relation_version_is_last": true, "title": ["Bystin in human cancer cells : intracellular localization and function in ribosome biogenesis"], "weko_shared_id": -1}
