miR - 153 - 3p调控AEG - 1抑制子宫内膜癌细胞上皮间质转化
miR-153-3p regulates AEG-1 to inhibit the epithelial-mesenchymal transformation of endometrial cancer cells
为探讨miR - 153 - 3p调控星形胶质细胞升高基因1(AEG - 1)对子宫内膜癌细胞上皮间质转化(EMT)的影响,体外培养人子宫内膜癌细胞Ishikawa,分为对照组、mimic NC组(转染mimic NC)、miR - 153 - 3p mimic组(转染miR - 153 - 3p mimic)、pcDNA3.1组(转染miR - 153 - 3p mimic、pcDNA3.1)和pcDNA3.1 - AEG - 1组(转染miR - 153 - 3p mimic、pcDNA3.1 - AEG - 1).结果显示,上调miR - 153 - 3p表达可显著提高Ishikawa细胞凋亡率、细胞中miR - 153 - 3p水平及Caspase - 3、E - 钙黏蛋白蛋白水平(P < 0.05),降低细胞侵袭数、细胞中AEG - 1 mRNA及AEG - 1、MMP - 9、N - 钙黏蛋白、波形蛋白、纤连蛋白蛋白水平(P < 0.05);在此基础上,上调AEG - 1表达可显著逆转上调miR - 153 - 3p表达的影响.miR - 153 - 3p与AEG - 1存在靶向关系.综上,miR - 153 - 3p可靶向抑制AEG - 1表达,抑制Ishikawa细胞EMT、侵袭行为,并诱导细胞凋亡.
To investigate the effect of miR - 153 - 3p regulating astrocyte elevated gene - 1 (AEG - 1) on the epithelial - mesenchymal transition (EMT) of endometrial cancer cells. Ishikawa human endometrial cancer cells were cultured in vitro and divided into control group, mimic NC group (transfected with mimic NC), miR - 153 - 3p mimic group (transfected with miR - 153 - 3p mimic), pcDNA3.1 group (transfected with mimic and pcDNA3.1) and pcDNA3.1 - AEG - 1 group (transfected with miR - 153 - 3p mimic and pcDNA3.1 - AEG - 1). The increase of miR - 153 - 3p expression significantly increased the apoptotic rate of Ishikawa cells, the level of miR - 153 - 3p and the levels of Caspase - 3 and E - cadherin proteins (P < 0.05), and decreased the number of cell invasion and the levels of AEG - 1 mRNA and AEG - 1, MMP - 9, N - cadherin, Vimentin and Fibronectin proteins(P < 0.05). On this basis, the increase of AEG - 1 expression can significantly reverse the effect of the increase of miR - 153 - 3p expression. miR - 153 - 3p and AEG - 1 had a targeting relationship in Ishikawa cells. In conclusion, miR - 153 - 3p can target and inhibit the expression of AEG - 1, inhibit the EMT and invasion behavior of Ishikawa cells, and induce cell apoptosis.
