In this study, we demonstrate the osteogenic effect of a low-molecular weight compound, SVAK-12, that potentiated the effects of BMP-2 in inducing transdifferentiation of C2C12 myoblasts into the osteoblastic phenotype. Here, we report a specific compound, SVAK-12, which was selected based on in silico screenings of small-molecule databases using the homology modeled interaction motif of Smurf1-WW2 domain. The enhancement of BMP-2 activity by SVAK-12 was characterized by evaluating a BMP-specific reporter activity and by monitoring the BMP-2-induced expression of mRNA for osteocalcin and alkaline phosphatase (ALP), which are widely accepted marker genes of osteoblast differentiation.

Smurf1 is an interesting potential target to enhance bone formation based on the positive effects on bone of proteins that block Smurf1-binding to Smad targets or in Smurf1-/- knockout mice. Since Smads bind Smurf1 via its WW2 domain, we performed in silico screening to identify compounds that might interact with the Smurf1-WW2 domain. We recently reported the activity of a compound, SVAK-3. However, SVAK-3, while exhibiting BMP-potentiating activity, was not stable and thus warranted a new search for a more stable and efficacious compound among a selected group of candidates. In addition to being more stable, SVAK-12 exhibited a dose-dependent activity in inducing osteoblastic differentiation of myoblastic C2C12 cells even when multiple markers of the osteoblastic phenotype were parallelly monitored. © 2010 Springer Science+Business Media, LLC.", "subitem_description_type": "Abstract"}]}, "item_4_description_5": {"attribute_name": "提供者所属", "attribute_value_mlt": [{"subitem_description": "金沢大学附属病院リハビリテーション部", "subitem_description_type": "Other"}]}, "item_4_publisher_17": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Springer Science+Business Media, LLC"}]}, "item_4_relation_12": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1007/s11010-010-0664-6", "subitem_relation_type_select": "DOI"}}]}, "item_4_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0300-8177", "subitem_source_identifier_type": "ISSN"}]}, "item_4_version_type_25": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kato, Satoshi"}], "nameIdentifiers": [{"nameIdentifier": "615", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "30584841", "nameIdentifierScheme": "金沢大学研究者情報", "nameIdentifierURI": "http://ridb.kanazawa-u.ac.jp/public/detail.php?kaken=30584841"}, {"nameIdentifier": "30584841", "nameIdentifierScheme": "研究者番号", "nameIdentifierURI": "https://nrid.nii.ac.jp/nrid/1000030584841"}]}, {"creatorNames": [{"creatorName": "Sangadala, Sreedhara"}], "nameIdentifiers": [{"nameIdentifier": "25996", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tomita, Katsuro"}], "nameIdentifiers": [{"nameIdentifier": "20094", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "00092792", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://kaken.nii.ac.jp/ja/search/?qm=00092792"}, {"nameIdentifier": "00092792", "nameIdentifierScheme": "研究者番号", "nameIdentifierURI": "https://nrid.nii.ac.jp/nrid/1000000092792"}]}, {"creatorNames": [{"creatorName": "Titus, Louisa"}], "nameIdentifiers": [{"nameIdentifier": "25997", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Boden, Scott D."}], "nameIdentifiers": [{"nameIdentifier": "25998", "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": "2017-10-03"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "HO-PR-KATO-S-97.pdf", "filesize": [{"value": "753.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 753300.0, "url": {"label": "HO-PR-KATO-S-97.pdf", "url": "https://kanazawa-u.repo.nii.ac.jp/record/14653/files/HO-PR-KATO-S-97.pdf"}, "version_id": "bc7d3ab9-2e0c-4153-a373-d0fd711dd35f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "BMP-2", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Potentiating", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Smad", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Smurf1", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Virtual screening", "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": "A synthetic compound that potentiates bone morphogenetic protein-2-induced transdifferentiation of myoblasts into the osteoblastic phenotype", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A synthetic compound that potentiates bone morphogenetic protein-2-induced transdifferentiation of myoblasts into the osteoblastic phenotype"}]}, "item_type_id": "4", "owner": "3", "path": ["1134"], "permalink_uri": "http://hdl.handle.net/2297/27096", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-10-03"}, "publish_date": "2017-10-03", "publish_status": "0", "recid": "14653", "relation": {}, "relation_version_is_last": true, "title": ["A synthetic compound that potentiates bone morphogenetic protein-2-induced transdifferentiation of myoblasts into the osteoblastic phenotype"], "weko_shared_id": -1}
