Mir-101-3p is a key regulator of tumor metabolism in triple negative breast cancer targeting AMPK.

ABSTRACT: mir-101-3p has been reported to be a tumor suppressor and a promising therapeutic target in cancer. Recently, AMPK dysfunction has been highlighted in cancers, including breast cancer. The aim of this study is to investigate the biological roles of mir-101-3p and AMPK in breast cancer. Our research demonstrated that AMPK was up-regulated in breast cancer tissues and cell lines, especially in triple negative breast cancer (TNBC). High-expression of AMPK correlated with poor outcome in both total breast cancer and TNBC patients. Ectopic expression of AMPK improved glucose uptake, glycolysis, proliferation of TNBC cells in vitro and its tumorigenicity in vivo. AMPK was predicted to be a direct target of mir-101-3p. The luciferase reporter assay was performed to certificate this prediction. Th
