چکیده
Purpose: The relative level of Wnt/β-catenin signaling pathway activity in breast cancer stem cells (BCSCs) is significantly higher than that in bulk cancer cells and therefore BCSCs could be sensitive to therapeutic approaches targeting Wnt/β-catenin signaling pathway. Methods: Murine mammary cancer cell lines were cultured. Small hairpin RNA (shRNA) targeted mouse Wnt pathway genes. Cell proliferation was assayed with cytotoxicity assay. Real-time quantitative PCR and Flow cytometry and Luciferase assays was performed. Results: Wnt/β-catenin signaling pathway activity is enhanced in malignant breast cancer tissues compared with their normal counterparts. Blockade ofWnt/β-catenin signaling pathway suppresses the growth and phenotypic characteristics of BCSCs and therefore this pathway regulates proliferation and apoptosis of breast cancer cells. Targeting of this signaling pathway suppresses breast cancer invasion, migration, tumor growth and metastasis. Discussion and conclusion: In conclusion, we have demonstrated that Wnt/β -catenin signaling regulates the self-renewal and migration of cancer stem cells (CSCs), thereby promoting tumor growth and metastasis/systemic dissemination in breast cancer. this signaling pathway could serve as a novel target in BCSCs for the treatment of breast cancer.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
