Outline of Final Research Achievements |
This research aimed to elucidate the presence of the protein C coagulation control system within cancer tissues. To clarify the presence of factor thrombomodulin, which is involved in the protein C coagulation control system within cancer tissues, we investigated the expression of thrombomodulin in cultured mouse vascular endothelial cells using the activation ability of thrombin-dependent protein C as an indicator. As a result, the activation of protein C was observed, suggesting the presence of thrombomodulin.

Academic Significance and Societal Importance of the Research Achievements |
最近では転移癌における組織因子発現、癌幹細胞でのプロテインC受容体の発現がそれぞれ増殖や転移を促進することが報告され、癌の発生や進行を制御しうる新しい機構として注目を集めている。我々もプロテインCインヒビターが細胞の癌化と癌細胞の増殖・転移を抑制することを示してきた。これまでの研究で明らかにされていない重要な課題が、癌組織内での血液凝固系・制御系反応に関わる分子実態とその病態生理機能であり、本研究は世界ではじめてその課題に取り組む先駆的な研究である。
