| Popis: | BACKGROUND: Breast cancer is the most common cancer in women, and triple-negative breast cancer (TNBC) accounts for about 15–20% of all breast cancer. High mobility group AT-hook 2 (HMGA2) is overexpressed in some tumors and closely associated with patients’ prognosis. However, the mechanisms involved in the regulation of HMGA2 in TNBC still remain unclear. METHODS: In this study, HMGA2 level in TNBC cell lines was analyzed by western blot. After knockdown of HMGA2 expression by RNA interference in TNBC cell lines MDA-MB-231 and SUM149, wound healing and transwell assays were conducted to examine the effects of HMGA2 on migration and invasion. Tumor metastasis was assessed in amouse xenograft model invivo. Furthermore, expression levels of epithelial–mesenchymal transition (EMT) biomarkers and involvement of the Hippo-YAP pathway were detected by western blot. RESULTS: Compared to normal breast epithelial cells, the expression levels of HMGA2 were significantly increased in TNBC cell lines (all P |
