circTRIM33-12调控miR-191/DAB2轴对脑胶质瘤细胞增殖、凋亡及上皮-间质转化的影响

目的 探讨circTRIM33-12通过miR-191/DAB2轴对脑胶质瘤细胞增殖、凋亡及上皮-间质转化（EMT）的影响及其作用机制。方法 RT-qPCR法检测circTRIM33-12、miR-191和DAB2在脑胶质瘤细胞CHG-5和人正常脑胶质上皮细胞HEB中的表达。将培养的CHG-5细胞进行分组：siRNA NC组、circTRIM33-12 siRNA组、DAB2 siRNA组；mimics NC组、miR-191 mimics组；circTRIM33-12 WT+mimics NC组、circTRIM33-12 WT+miR-191 mimics组、circTRIM33-12 MUT+mimics NC组、circTRIM33-12 MUT+miR-191 mimics组；inhibitor NC组、miR-191 inhibitor组；pcDNA+mimics NC组、pcDNA-TRIM33-12+mimics NC组、pcDNA+miR-191 mimics组、pcDNA-TRIM33-12+miR-191 mimics组；DAB2 WT+mimics NC组、DA...
