Outline of Final Research Achievements

In the case of producing a recombinant to antithrombin resistant prothrombin and a recombinant protein of mutant blood coagulation factor X using HEK 293 cells, it was found that high-expression clones were insufficient in gamma carboxylation.The moderately expressing clones were more efficient for the formation of Gla and were superior as the experimental materials.In antithrombin resistance detection, heparins in the sample plasma had a small effect on the activation phase of prothrombin and FX, but promoted inactivation in the inactivation phase. These effects could be avoided by adding polybrene to the sample plasma dilution. The small molecule antithrombotic agents that acted directly on the active center had a small effect on the activation phase, but inhibited the inactivation in the inactivation phase, resulting in similar results to antithrombin resistance.

Academic Significance and Societal Importance of the Research Achievements

凝固因子の先天性分子異常(1アミノ酸置換)が凝固因子の機能不全による出血傾向ではなく、不活化不全により血栓症の原因になるアンチトロンビン抵抗性を示すことを報告した2012年以来、アンチトロンビン抵抗性検出法を開発・改良してきた。しかし、血栓症を発症した患者は血栓症の原因を究明する前に抗血栓薬が投与されることも多く、検査結果の解釈を困難にしていた。今回ヘパリン類の抗血栓薬の影響を回避するアンチトロンビン抵抗性検出法に改良することができた。低分子の活性中心に直接作用するタイプの抗血栓薬はアンチトロンビン抵抗性を示すことは判明したが回避法は開発できなかった。
