Outline of Research at the Start

多発性骨髄腫は、近年の新規治療薬を用いても救命し得ない症例が多く存在する。その原因は、治療抵抗性の獲得、髄外病変形成、免疫能の破綻といった悪性形質に起因する。本研究では、悪性化の決定因子は何かについて、レナリドミド抵抗性細胞や脱分化を来した細胞株を樹立して上皮間葉系移行(EMT)やリプログラミング、薬剤耐性に関わるエクソソームの解析等の観点からその分子機構に切り込む。いわゆるハイリスク骨髄腫では、このような悪性化をきたしやすく、天然物や既存薬ライブラリーから克服薬の開発を推進する。これまでに候補化合物が複数分離されており、その分子薬理機構の解明とバイオマーカーの開発を進める。

Outline of Final Research Achievements

We obtained following research results on malignant phenotype of myeloma. ①Molecular pathogenesis: We established lenalidomide-resistant cell lines and found that increased exosome secretion and integrin-mediated cell adhesion play roles in drug resistance. RNA sequence revealed signal transducing molecules which may associated with formation of extramedullary disease. ②Drug development: Novel phthalimide, TC11, induced mitotic catastrophe by inhibition of tubulin polymerization and constitutive phosphorylations of NPM1. GTN057, a derivative of natural compound komaroviquinon, inhibited c-MET/HGFR kinase activity in myeloma cells. We also challenging isolation of autophagy inhibitors by drug repositioning. ③New biomarker: Immunohistopathological examination of myeloma patients’ samples revealed that negative change of E-cadherin expression in myeloma cells is associated with formation of extramedullary disease and poor prognosis.

Academic Significance and Societal Importance of the Research Achievements

骨髄腫が治癒困難であるかの問いに関し、治療抵抗性の獲得と髄外病変形成という具体的な臨床上の問題点を挙げて、その分子病態解明と克服を目指した創薬研究を展開してきた。その結果、悪性化を決定する分子群やEMT様現象やエクソソームといった新たな細胞機能を提示し、将来の克服薬としての新規候補化合物も複数同定することができた。このことは、造血器腫瘍である骨髄腫の病態解明に、新たな切り口を提案するものであり、その学術的独創性は高い。同時に、以上の成果は不治の造血器腫瘍とされる骨髄腫の予後推測や治療法決定に直結するものであり、患者の救済の観点からその社会的意義も高い。さらに他の癌腫にも応用できるものである。
