肺癌已經是台灣多年來死亡率第一名的癌症。轉移是治療肺癌最重要挑戰。中草藥重樓皂苷萃取物Formosanin C(FC)被發現可以藉由誘導降解型細胞自噬以及透過抑制組織金屬蛋白酶(MMPs)來降低肺癌轉移。降解型細胞自噬為細胞分解胞內物質以維持細胞能量平衡的方式。在肺癌細胞,人類小型GTPase Rab37增加金屬蛋白酶組織抑制劑(TIMP1)透過「分泌型細胞自噬」,降低MMP9的分泌以抑制肺癌轉移。本研究發現FC能夠(1)毒殺肺癌細胞CL1-5,(2)提高肺癌細胞的細胞自噬作用,其路徑與提高ATG7和Ras/MEK/ERK路徑的表現有關,(3)增加p62來抑制肺癌細胞的爬行。然而,在肺癌治療上,FC是否輔助化療藥物以發揮肺癌細胞致死的效果還有待更多證據釐清。
