Outline of Final Research Achievements |
In this project, we performed kinetic studies using stable isotope in 3 homozygous patients with sitosterolemia. We found that there were no significant changes in VLDL apoB kinetic parameters, but there were marginally elevated LDL apoB concentration which were due to significantly delayed rates of catabolism. In conclusions, sitosterolemia is associated with impaired LDL apoB catabolism, resulting in elevated LDL apoB concentrations. While VLDL and IDL apoB metabolism are preserved in sitosterolemia.

Academic Significance and Societal Importance of the Research Achievements |
シトステロール血症は平成27年難病してされ、国としても病態解明に注力している疾患である。本研究は、世界で初めての試みで、シトステロール血症でLDLの代謝障害があることを見いだした。今後、この知見に基づいた治療への展開が期待される。
