We identified the downregulation of circDDX17 in breast cancer, and circDDX17 acted as a tumour suppressor by inhibiting proliferation and promoting apoptosis through its function as a sponge of miR-605 in breast cancer, indicating that it serves as a potential biomarker and a therapeutic target for breast cancer.
CircDDX17 acts as a competing endogenous RNA for miR-605 in breast cancer progression.
