Carcinoma-Associated Fibroblasts Derived Exosomes Modulate Breast Cancer Cell Stemness through Exonic circHIF1A by miR-580-5p in Hypoxic Stress

Through investigating cellular functions including cell proliferation and stem cell features, it was demonstrated that hypoxic cancer-associated fibroblasts exosomes transferred circHIF1A into breast cancer cells, which played an important role in cancer stem cell properties sponging miR-580-5p by regulating CD44 expression.
