摘要: 目的 观察EGFL7单克隆抗体对小鼠ACTH垂体腺瘤AtT-20细胞增殖和侵袭的影响。方法 MTS试验检测不同浓度EGFL7单克隆抗体处理AtT-20细胞24、48、72 h后细胞增殖活力。ELISA检测不同浓度的EGFL7单克隆抗体处理AtT-20细胞72 h后细胞上清中ACTH的分泌水平。Real-time PCR检测AtT-20细胞经EGFL7单克隆抗体处理24 h后细胞中侵袭相关基因E-cadherin、snail、vimentin的mRNA表达水平。结果 EGFL7单克隆抗体能够有效抑制AtT-20细胞增殖,并呈现良好的时间依赖性与浓度依赖性;同时能够显著降低AtT-20细胞分泌ACTH,呈现良好的剂量依赖作用。Real-time-PCR结果表明EGFL7单克隆抗体能够显著抑制AtT-20细胞中侵袭相关基因E-cadherin、snail、vimentin的mRNA表达。结论 EGFL7单克隆抗体可以显著抑制AtT-20细胞的增殖和侵袭。

Abstract: Objective To study the effects of EGFL7-blocking monoclone antibody inhibiting the proliferation and invasion of adrenocorticotropic hormone (ACTH) pituitary adenoma AtT-20 cells in vitro. Methods After treated with different concentrations of EGFL7-blocking monoclone antibody for 24, 48, 72 h, the proliferation of AtT-20 cells was determined by MTS. Simultaneously, ACTH secretion of AtT-20 cells by ELISA and the mRNA expression of invasion related genes such as E-cadherin, snail, vimentin were detected by Real-time PCR. Results EGFL7-blocking monoclone antibody could effectively inhibit the proliferation and ACTH secretion of AtT-20 cells in a dose-dependent and time-dependent manner. Also, EGFL7-blocking monoclone antibody significant down-regulated the mRNA level of E-cadherin、snail, vimentin in AtT-20 cells. Conclusion EGFL7-blocking monoclone antibody could inhibit mouse pituitary adenoma AtT-20 cells proliferation and invasion.
