Moreover, continuous exposure to HGF accelerates the emergence of EGFR-TKI-resistant clones. We assayed whether a new Met kinase inhibitor, E7050, which is currently being evaluated in clinical trials, could overcome these three mechanisms of resistance to EGFR-TKIs. EXPERIMENTAL DESIGN: The effects of E7050 on HGF-induced resistance to reversible (gefitinib), irreversible (BIBW2992), and mutant-selective (WZ4002) EGFR-TKIs were determined using the EGFR-mutant human lung cancer cell lines PC-9 and HCC827 with an exon 19 deletion, and H1975 with an T790M secondary mutation. PC-9 cells were mixed with HGF-producing fibroblasts, MRC-5 cells, and subcutaneously inoculated into SCID mice and the therapeutic effects of E7050 plus gefitinib were assayed. RESULTS: E7050 circumvented resistance to all of the reversible, irreversible, and mutant-selective EGFR-TKIs induced by exogenous and/or endogenous HGF in EGFR mutant lung cancer cell lines, by blocking the Met/Gab1/PI3K/Akt pathway in vitro. E7050 also prevented the emergence of gefitinib-resistant HCC827 cells induced by continuous exposure to HGF. In the in vivo model, E7050 plus gefitinib resulted in marked regression of tumor growth associated with inhibition of Akt phosphorylation in cancer cells. CONCLUSIONS: A new Met kinase inhibitor, E7050, reverses the three HGF-induced mechanisms of gefitinib resistance, suggesting that E7050 may overcome HGF-induced resistance to gefitinib and next-generation EGFR-TKIs.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学がん進展制御研究所","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00027435","subitem_identifier_reg_type":"JaLC"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1158/1078-0432.ccr-11-1171","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ncbi.nlm.nih.gov/pubmed/22317763","subitem_relation_type_select":"URI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11029881","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1078-0432","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":"Wang, Wei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Li, Qi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeuchi, Shinji"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Yamada, Tadaaki"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Koizumi, Hitomi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Takahiro"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Matsumoto, Kunio"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Mukaida, Naofumi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Nishioka, Yasuhiko"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Sone, Saburo"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Nakagawa, Takayuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uenaka, Toshimitsu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yano, Seiji"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"CA-PR-TAKEUCHI-S-2012.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"CA-PR-TAKEUCHI-S-2012.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/27448/files/CA-PR-TAKEUCHI-S-2012.pdf"},"version_id":"7c740539-0d7f-48a2-8a31-3971032caab9"}]},"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":"Met Kinase Inhibitor E7050 Reverses Three Different Mechanisms of Hepatocyte Growth Factor-induced Tyrosine Kinase Inhibitor Resistance in EGFR Mutant Lung Cancer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Met Kinase Inhibitor E7050 Reverses Three Different Mechanisms of Hepatocyte Growth Factor-induced Tyrosine Kinase Inhibitor Resistance in EGFR Mutant Lung Cancer"}]},"item_type_id":"4","owner":"3","path":["1779"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"27448","relation_version_is_last":true,"title":["Met Kinase Inhibitor E7050 Reverses Three Different Mechanisms of Hepatocyte Growth Factor-induced Tyrosine Kinase Inhibitor Resistance in EGFR Mutant Lung Cancer"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:12:57.480896+00:00"}
