Outline of Final Research Achievements

In this research, we investigated the function of DKK3 gene in head and neck squamous cell carcinoma (HNSCC). We previously reported that DKK3 may exert oncogenic function particularly in HNSCC, while DKK3 has been reported as tumor suppressor gene. We established DKK3 over-expression model by transfection of DKK3 expression plasmid and stable knockdown model by lentivirus-mediated transfer of shRNA for DKK3. Our data have shown that DKK3 over-expression resulted in significantly increased cellular proliferation, migration and invasion with increased phosphorylation of Akt (Ser 473). Correspondingly, DKK3 stable knockdown significantly decreased these, together with decreased phosphorylation of Akt (Ser473). We suggested that activation of Akt by DKK3 may be driven by two independent pathways; by the binding of secreted DKK3 to unknown receptor and by activation of mTOR pathway.
These results strongly imply that DKK3 may be the encouraging candidate of targeted therapy of HNSCC.

Academic Significance and Societal Importance of the Research Achievements

わが国では年間で約1.8万例のHNSCCが発生するが、その5年生存率は76.2%であり、転移を伴う場合は40%程度にとどまる(国立癌研究センター2014年統計)。HNSCCの治療成績向上のために、腫瘍ごとに存在する特有の遺伝子発現プロファイルと分子基盤の理解に基づく分子標的創薬が求められている。申請者はそのターゲット候補としてDKK3を同定し研究を続けている。本研究ではDKK3の詳細な機能解析を行い、DKK3がHNSCCの治療および創薬のターゲットとなりうることを明らかにした。本研究成果は創薬の実現に向けての基礎データとなり、その意義は非常に大きい。
