Breast cancer is one of the dominant cancers of women-related death universal. This inquiry aims to disclose the probable role of circABCC4 in breast cancer. The level of circABCC4 was discovered through qRT-PCR. The reactions of circABCC4 and miR-154-5p on the cell viability, apoptosis, migration as well as invasion were, respectively, inspected by CCK-8, flow cytometry, and transwell assays. The association betwixt circABCC4 and miR-154-5p was investigated. The accumulation of NF-kappa B and Wnt/beta-catenin pathway proteins was discovered through Western blot. The expression of circABCC4 was far great in tumor tissues than in normal tissues. Knockdown of circABCC4 could subdue cell viability, migration, invasion, and enhance apoptosis in breast cancer cell lines. CircABCC4 negatively regulated the manifestation of miR-154-5p and shared binding sites with the latter. Suppression of miR-154-5p expression partially conversed the repressive effect of circABCC4 knockdown on breast cancer cell viability, migration, invasion, and NF-kappa B and Wnt/beta-catenin pathways. CircABCC4 knockdown repressed breast cancer cells viability, migration, and invasion by up-regulating miR-154-5p via inhibiting NF-kappa B and Wnt/beta-catenin signal pathways.
