摘要: In human esophageal squamous cell carcinoma (ESCC), miR-34a was downregulated and could inhibit in vitro proliferation migration. However, the underlying mechanism not clear yet. The expression levels of mRNA protein were detected by quantitative real-time PCR or western blotting, respectively. MiR-34a knocked down overexpressed transfected into ESCC lines ECA109 TE-13, Cell migration wound healing assays used to examine effect on invasion vitro. Animal models role metastasis vivo.
