【摘要】:目的:由于AZD2014是TOR蛋白激酶的抑制劑,因此通過觀察不同濃度AZD2014在體外培養(yǎng)的細(xì)粒棘球蚴原頭蚴的活性,從而得到AZD2014作用于原頭蚴的相對最適濃度,進(jìn)一步驗證了原頭蚴體內(nèi)存在TOR蛋白激酶;并通過阻斷原頭蚴體內(nèi)的TOR蛋白激酶活性,從而阻斷PI3K-AKT-TOR細(xì)胞信號通路,進(jìn)而殺滅囊泡內(nèi)的原頭蚴,為靶向藥物治療包蟲病提供理論和研究基礎(chǔ)。方法:1.不同濃度的AZD2014在體外培養(yǎng)細(xì)粒棘球蚴原頭蚴,通過0.1%的伊-紅染色后觀察原頭蚴的存活率,并連續(xù)觀察15天同時統(tǒng)計其存活率;2.不同濃度AZD2014體外培養(yǎng)原頭蚴4天后,取其蛋白上清液,用Western-blot驗證TOR下游蛋白因子的表達(dá)情況,用ELISI試劑盒檢測Caspase-3酶活性的表達(dá);3、用100μM的AZD2014培養(yǎng)原頭蚴1天,4天,7天后,取其蛋白上清液,用Western-blot驗證TOR下游蛋白因子的表達(dá)情況,用ELISI試劑盒檢測Caspase-3酶活性的表達(dá)。結(jié)果:1、隨AZD2014培養(yǎng)濃度的增大而原頭蚴的存活率逐漸下降,隨AZD2014培養(yǎng)時間的延長而原頭蚴的存活率逐漸下降;2、Western-blot驗證TOR蛋白下游蛋白因子p-AKT,p-S6K1,p-4EBP1的表達(dá)量隨AZD2014濃度的增大而下降,且隨AZD2014培養(yǎng)時間的延長而下降(P㩳0.05);3、ELISI驗證Caspase-3的活性隨AZD2014培養(yǎng)濃度的增大而升高,且隨AZD2014培養(yǎng)時間的延長而升高(P㩳0.05)。結(jié)論:1、AZD2014通過抑制原頭蚴體內(nèi)的TOR蛋白而具有殺滅原頭蚴的作用;2、AZD2014殺滅體外培養(yǎng)的細(xì)粒棘球蚴原頭蚴具有時間和濃度的依賴性。
