Outline of Final Research Achievements |
Liver X receptor (LXR) activity is expected to have an innovative effect of extracting cholesterol from once formed atherosclerotic lesions and regressing arteriosclerosis, but it also induces a lipid synthesis system gene (SREBP1c). It has the drawback of further exacerbating hepatic lipid deposition. In this study, in order to overcome this drawback, the applicants have a special purpose (1): the inhibitory effect of bile acid on SREBP1c activity and the purpose (2): the efficacy of vabagenin, which is a novel ligand candidate for LXR activity that does not activate SREBP1c. As a result of examination using the NASH- myocardial infarction onset model (SHRSP5 / Dmcr rat), the lipid deposition in the arteries was improved without aggravating fatty liver.

Academic Significance and Societal Importance of the Research Achievements |
非アルコール性脂肪性肝炎(NASH)は、大きな自覚症状がないことから長年軽視されてきた。しかしながら、NASHが肝硬変、肝がんに移行することが明らかとなったことで、積極的な治療ターゲットという認識に変わってきた。また、NASHは肝臓だけにとどまらず、メタボリックシンドロームを背景とした糖尿病、脂質異常症、高血圧を悪化させ、虚血性心疾患の発症率と死亡率を2倍以上高くすることも、予後を悪くする原因となっている。増大する医療費を削減するため、自覚症状が少ない早期のNASHのうちから、積極的な治療介入を行うことができれば、致死的な虚血性心疾患への進行を事前に食い止めることができる。
