Outline of Research at the Start

本研究では、
①卵巣癌患者の腹水を回収し、BMPリガンドとTWSG1の分泌を蛋白レベルで検出し、同時にBMP経路の活性化を卵巣癌検体のリン酸化SMAD1/5/8の免疫組織化学で評価し、相関関係を明らかにし、
②TWSG1が卵巣癌に於いて腫瘍抑制効果を持つか、細胞株を用いた実験を同所移植または腹腔内投与マウスモデルを含めて施行し、
③卵巣癌細胞株に様々なリガンドやホルモンを添加後の発現を評価し、制御メカニズムを解明し、TWSG1を標的とした分子標的治療を探索するため、研究を遂行予定である。

Outline of Final Research Achievements

Using ovarian cancer cell lines, we showed that TWSG1 inhibited both SMAD1/5/8 phosphorylation and mRNA expression of ID1 and SNAIL by BMP7. Furthermore, TWSG1 antagonized BMP7-induced enhancement of sphere formation and cell migration in sphere formation and cell migration assays. Thus, TWSG1 is a BMP7 antagonist and functions as a tumor suppressor gene. In the evaluation of clinical uterine cancer specimens, TWSG1 mRNA levels were significantly decreased in patients with vascular invasion and high grade cases.

Academic Significance and Societal Importance of the Research Achievements

卵巣癌は早期に腹腔内播種を引き起こす事が知られており、様々な分子標的治療が登場した現在でも難治性の悪性腫瘍である。我々の過去の報告から、BMP経路は卵巣癌の腹腔内播種を亢進させる可能性が示唆される。本研究ではTWSG1がBMP7に拮抗する事で、卵巣癌の腹腔内播種を抑制する可能性が示された。詳細なTWSG1の発現制御メカニズムを同定出来れば、卵巣癌患者に於いて、TWSG1の発現亢進を引き起こす事で卵巣癌の腹腔内播種をコントロールし、予後の改善に繋がる可能性があり、有望な新規分子標的治療になる事が期待される。
