Identification and Validation of circDOCK1/miR-138-5p/GRB7 Axis for Promoting Breast Cancer Progression.

Background: Non-coding RNAs have received increasing attention in human tumors, with RNA interaction networks playing important roles in breast cancer. This study aims to explore novel circular RNAs and their mechanisms of biological function in breast cancer.

Methods: Six HER2-positive breast cancer tissues and paired normal tissues were obtained for the whole transcriptome RNA sequencing.
