Project Details

Description

MBTPS1 (Site-1蛋白酶)是調控細胞內脂質代謝之酵素,PF-429242是一個MBTPS1抑制劑,近年來被認為是具有潛力之抗癌藥物,本計畫發現PF-429242可誘導肝癌細胞自噬作用而造成細胞死亡,其機轉與其原本抑制MBTPS1作用無關,而是透過FOXO1轉錄因子所造成,此外PF-429242也會促進IGFBP1表現,而抑制IGF所參與之細胞增生及存活訊號,因此PF-429242之抗肝癌活性與其誘導FOXO1依賴性細胞自噬,以及IGFBP1依賴性細胞增生及存活訊號抑制有關,我們的發現闡明PF-429242之抗肝癌作用及相關分子機轉。
