The inhibition of circNOLC1 attenuates cancer stem cell activity of breast cancer. A–F The MDA-MB-231 and MDA-MB-468 cells were treated with circNOLC1 shRNAs. A and B The SP ration was identified by Hoechst 33342 staining using flow cytometry analysis. C and D The sphere formation ability was determined by sphere formation assays. E and F The protein levels of ABCG2, C-Myc, Bmi1, Sox2 were detected by Western blot analysis. **P < 0.01
