2、e9的誘導(dǎo)作用均隨著濃度的增大而增強(qiáng),對(duì)P53的抑制作用也隨著濃度的增大而增強(qiáng)。結(jié)論養(yǎng)麥七水提物及蒽醌能抑制人肺癌A549細(xì)胞的增殖,并誘導(dǎo)其凋亡,其機(jī)制可能與上調(diào)Caspase9的表達(dá)及下調(diào)P53的表達(dá)有關(guān)。【關(guān)鍵詞】蕎麥七;中草藥;肺腫瘤;細(xì)胞凋亡EfectsofFagopyrumcymosumextractsonproliferationandapoptosisoflungcancercelllineA549Lijian*,WangXiaomei,YangChu~juan,LiuFan.*DepartmentofTraditionalChineseMedicine,Bao
