Outline of Final Research Achievements |
BMP4 is expected to be a novel treatment for neuroblastoma. BMP4, which is involved in neural development, inhibits angiogenesis in solid tumors (cervical cancer, metastatic lung cancer, melanoma) and provides tumor suppression without damaging existing normal blood vessels. With especially respect to neuroblastoma cells, administration of BMP4 inhibited the growth of the cells themselves, and animal experiments showed a remarkable tumor suppressor effect. By RNA sequence analysis, BMP4 suppressed the expression of MYCN gene, which is often recognized in neuroblastoma, and confirmed the decrease in expression of MYCN protein. Furthermore, it was also found that the genes related to cancer stem cells regulate neuroblastoma suppression associating with the MYCN gene expression.

Academic Significance and Societal Importance of the Research Achievements |
小児固形腫瘍として頻度の高い神経芽細胞腫の予後は極端に分かれており、自然に退縮する腫瘍がある一方で、非常に悪性度を増し難治性腫瘍となる場合がある。本研究ではヒトの神経発生とその分化に必須であるBMP4が、神経芽細胞腫の著明な腫瘍抑制効果をもたらし、その作用機序としてMYCN遺伝子発現低下とがん幹細胞に関わる遺伝子の制御に関与することを見いだした。神経芽細胞腫は元来がん幹細胞様の性質を持つため、BMP4シグナル経路がその予後の良悪を決定づけるON/OFF効果を担っている可能性がある。BMP4の投与は既存の血管を傷害しないため、副作用を避け、神経芽細胞腫の完全治癒を目指せる治療薬として期待できる。
