摘要: 目的 探讨去酰基化ghrelin(DAG)对上皮性卵巢癌细胞增殖的作用及其相关分子机制。方法 培养上皮性卵巢癌细胞SKOV3,以DAG处理,并予以激动剂干预哺乳动物雷帕霉素靶蛋白(mTOR)和经典Wnt信号途径,采用CCK-8法测定细胞增殖。结果 DAG呈剂量依赖性抑制卵巢癌SKOV3细胞的增殖。DAG抑制mTOR信号途径,抑制经典Wnt信号转录活性以及下游靶基因的mRNA水平,mTOR和Wnt信号激活可在一定程度上翻转DAG对SKOV3细胞增殖的抑制作用。结论 DAG通过抑制mTOR和经典Wnt信号通路发挥其抑制卵巢癌细胞增殖的作用,为卵巢癌防治提供新思路。

Abstract: Objective To assess the effect of des-acyl ghrelin (DAG) on the proliferation of ovarian epithelial carcinoma cells and the related mechanism. Methods SKOV3 ovarian epithelial carcinoma cells were cultured and treated with DAG,with or without mammalian target of rapamycin (mTOR) and Wnt signaling pathway activator. Cell proliferation was measured by the CCK-8 assay. Results DAG inhibited the proliferation and growth of SKOV3 cells in a dose-dependent manner. DAG exposure induced the inhibition of the mTOR and Wnt signaling pathways. Activation of these two pathways blocked the inhibition of SKOV3 cell proliferation by DAG. Conclusion DAG inhibits the proliferation of SKOV3 ovarian epithelial carcinoma cells through the mTOR and Wnt signaling pathways,and may contribute to prevention and therapy of ovarian epithelial carcinoma.

Key words: des-acyl ghrelin, ovarian epithelial carcinoma, proliferation, mTOR signaling pathway, Wnt signaling pathway
