摘要: Differentiation antagonizing non-protein coding RNA (DANCR) is a newly identified oncogenic long noncoding found in various cancers. However, the functional role of DANCR tumor angiogenesis and underlying mechanisms are still unclear. The expression was determined ovarian malignant tissues cell lines. revealed by following methods: CD31 staining tissues, matrigel-plug assay HUVEC-related tube formation assay, invasion assay. Enzyme-linked immunosorbent Western blotting, luciferase rescue experiments were used to investigate DANCR-regulating angiogenesis. upregulated cancer cells. Knockdown efficiently impaired growth through inhibition Furthermore, conditional culture medium from DANCR-knockdown cells significantly inhibited HUVEC vitro. Mechanistic investigation indicated that vascular endothelial factor A (VEGF-A, VEGF) plays crucial during cancer. Further results demonstrated miR-145 direct binding target regulation VEGF Collectively, promotional miR-145/VEGF axis. Therefore, may be novel therapy for
