OAT2 was newly found as the uric acid transporter in kidney. As the animal model, uric transporters expressed in rats were characterized and found to be useful as the model of uric acid disposition. In addition, as the extra-renal elimination pathways of uric acid, intestinal secretion was found to be very important and the BCRP transporter was found to be responsible for that process. Furthermore, for in vivo analysis in human, the method for the synthesis of PET probe of uric acid was succeeded. It was preliminarily applied in PET analysis in rats. All these studies related to the mechanism and evaluation method of uric acid disposition is useful for future development of drugs that can control serum uric acid level and physiological and pathological significance of uric acid., 研究課題/領域番号:21390044, 研究期間(年度):2009-2011, 出典:研究課題「尿酸動態調節機構の解明に基づく血清尿酸値変動評価システムの樹立」課題番号21390044 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-21390044/21390044seika/)を加工して作成}, title = {尿酸動態調節機構の解明に基づく血清尿酸値変動評価システムの樹立}, year = {2012} }
