Although surgery, chemotherapy, radiotherapy, and combinations of these therapies are used to treat <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content>, the median survival of such patients is dismal. Therefore, there is a compelling need to develop novel therapeutics with different modes of action. Ganglioside <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 is a glycolipid that has been shown to be overexpressed in various types of cancer. However, there are no published reports regarding the use of <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 as a potential therapeutic target in cases of <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content>. In this study, we evaluated the efficacy of the anti\u2010<jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 antibody <jats:styled-content style=\"fixed-case\">BIW<\/jats:styled-content>\u20108962 as an anti\u2010<jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> therapeutic using <jats:italic>in vitro<\/jats:italic> and <jats:italic>in vivo<\/jats:italic> assays. Consequently, the <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 expression in the <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> cell lines was confirmed using flow cytometry. In addition, eight of 11 cell lines were <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2\u2010positive (73%), although the <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 expression was variable. <jats:styled-content style=\"fixed-case\">BIW<\/jats:styled-content>\u20108962 showed a significant antibody\u2010dependent cellular cytotoxicity activity against the <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2\u2010expressing <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> cell line <jats:styled-content style=\"fixed-case\">MSTO<\/jats:styled-content>\u2010211H, the effect of which depended on the antibody concentration and effector\/target ratio. In an <jats:italic>in vivo<\/jats:italic> orthotropic mouse model using <jats:styled-content style=\"fixed-case\">MSTO<\/jats:styled-content>\u2010211H cells, <jats:styled-content style=\"fixed-case\">BIW<\/jats:styled-content>\u20108962 significantly decreased the incidence and size of tumors. Additionally, the <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 expression was confirmed in the <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> clinical specimens. Fifty\u2010eight percent of the <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> tumors were positive for <jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2, with individual variation in the intensity and frequency of staining. These data suggest that anti\u2010<jats:styled-content style=\"fixed-case\">GM<\/jats:styled-content>2 antibodies may become a therapeutic option for <jats:styled-content style=\"fixed-case\">MPM<\/jats:styled-content> patients.<\/jats:p>","DOI":"10.1111\/cas.12575","type":"journal-article","created":{"date-parts":[[2014,11,25]],"date-time":"2014-11-25T05:42:54Z","timestamp":1416894174000},"page":"102-107","source":"Crossref","is-referenced-by-count":10,"title":["Therapeutic activity of glycoengineered anti\u2010<scp>GM<\/scp>2 antibodies against malignant pleural mesothelioma"],"prefix":"10.1111","volume":"106","author":[{"given":"Qi","family":"Li","sequence":"first","affiliation":[{"name":"Division of Medical Oncology Cancer Research Institute Kanazawa University Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Medical Oncology Cancer Research Institute Kanazawa University Kanazawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusuke","family":"Machino","sequence":"additional","affiliation":[{"name":"Oncology Research Laboratories R&amp;D Division Kyowa Hakko Kirin Co., Ltd.
