Outline of Final Research Achievements

Glioma stem cells (GSCs) are highly expressing cancer testis antigen (CTA) genes. To develop the CTA gene-targeted therapy for malignant glioma, we established the spheroid culture containing GSCs from glioma tissues and performed the genotyping including IDH mutation and 1p19q co-deletion. Among 67 CTA genes highly expressing in glioma tissue and GSCs or having prognostic correlation with their expression, the CTA genes were screened by siRNA-mediated silencing for an affect on cell growth. Growth inhibitions were found in 15 CTA genes by knockdown. This result suggests that a part of CTA gene family regulates cell growth in malignant glioma.

Academic Significance and Societal Importance of the Research Achievements

膠芽腫は、精力的な新規治療法の開発にも拘わらず、長い間、顕著な治療成績の向上が得られていない原発性脳腫瘍であり、平均余命は僅か1年数ヶ月である。この腫瘍の治療抵抗性は、放射線治療や化学療法への感受性の低さ、浸潤能の高さに起因している。本課題では、膠芽腫の幹細胞において高発現するがん精巣抗原遺伝子細胞増殖の制御に関わることを示した。膠芽腫細胞株において、その発現抑制により、細胞増殖を阻害するがん精巣抗原遺伝子を同定し、治療標的分子として有用である可能性を示すことが出来た。今後、この結果は、新たな脳腫瘍に関連する分子や経路の解析や同定に貢献し、根治を目指した遺伝子治療への応用も見込まれる。
