CircATXN7 contributes to the progression and doxorubicin resistance of breast cancer via modulating miR-149-5p/HOXA11 pathway.

Breast cancer is a frequent tumor threatening the health of women. Circular RNAs (circRNAs) play vital roles in cancer progression and chemoresistance. Herein, we mainly investigate the role and potential mechanism of circRNA ataxin 7 (circATXN7; circ_0066436) in breast cancer.
