Abstract Title:
Berberine Inhibits Proliferative Ability of Breast Cancer Cells by Reducing Metadherin.
Abstract:
BACKGROUND Breast cancer is a common malignant tumor worldwide. Despite the huge advances in modern medicine, many patients still face a high risk of recrudescent and metastatic breast cancer. Berberine was widely implemented in clinic treatment of breast cancer. This study was performed to contribute to a better understanding on the mechanisms underlying berberine affecting breast cancer. MATERIAL AND METHODS We mined survival data of metadherin (MTDH) in breast cancer patients through Kaplan-Meier Plotter and analyzed the transcriptional and posttranscriptional expression profile of MTDH in several breast cancer cell lines. The cell viability and MTDH mRNA level were detected under the si-MTDH vector and different concentrations of berberine. The MTDH-expression vector was transfected into MCF-7 and MDA-MB-231 cells, and the changes of cell viability and apoptosis were determined after berberine (50μM) treatment. RESULTS High MTDH expression was related to worse relapse-free survival (RFS) of breast cancer (P-value=6.2e-08). High-expressed MTDH is common in breast cancer cells, compared with that in normal breast cells (P
