Abstract

Tumor proliferation, drug resistance and cell stemness are major difficulties that are encountered during breast cancer therapy and are often responsible for disease progression and cancer‑related mortality. β‑catenin is considered to be an invasion gene in breast cancer. However, how β‑catenin regulates breast cancer cell proliferation and stemness remains unclear. In the present study, β‑catenin knockdown by small interfering RNA in MDA‑MB‑468, a highly metastatic breast cancer cell line, inhibited the expression of β‑catenin, Oct3/4 (stemness), survivin (anti‑apoptosis) and BCRP (drug resistance). Knockdown of β‑catenin enhanced the effects of fluorouracil (5‑FU) chemotherapy on the proliferation of MDA‑MB‑468 cells. Thus, these preliminary results indicate that β‑catenin knockdown enhanced 5‑FU‑induced proliferation inhibition in the breast cancer cell line MDA‑MB‑468, and indicate that combining 5‑FU with gene silencing could be an advantageous option for enhancing the curative effect of chemotherapy in breast cancer and other malignancies.
