研究概要

(1)腹部脂肪、肝臓、骨格筋、心臓周囲脂肪および筋量を非侵襲的に測定し、異所性脂肪分布様式を検証した。玄米食介入で減量および血管内皮機能改善効果を確認した。 (2)飽和脂肪酸処理されたヒト臍帯静脈血管内皮細胞(HUVEC)でプロテオーム ・トランスクリプトーム解析をおこない、発現変動の顕著な産物Xを同定した。分子X siRNAを過剰発現したHUVECでは、飽和脂肪酸による細胞死が、カスパーゼ3,7切断を阻害することで抑制された。 (3)心臓手術症例で、心臓脂肪発現シグナルと全身および心臓脂肪分布との関係を検証した。心臓バイパス手術症例は、心臓周囲脂肪量が増加して炎症性シグナルが増加していた。
