CircMMP11 regulated miR-625-5p/ZEB2 axis in breast cancer cells. a–c Pearson’s correlation analysis was used to reveal correlation relationship among circMMP11, miR-625-5p, and ZEB2 in breast cancer tissues. d The expression level of miR-625-5p was assessed by RT-qPCR in MCF-7 and MDA-MB-231 cells transfected with in-miR-con or in-miR-625-5p. e, f The expression levels of ZEB2 were measured by western blot assay in MCF-7 and MDA-MB-231 cells transfected with si-NC, si-circMMP11#2, si-circMMP11#2 + in-miR-co, or si-circMMP11#2 + in-miR-625-5p. **P < 0.01, ***P < 0.001
