ZNF407-AS1 and ovarian carcinoma: In biological functions, we demonstrated that loss-function of LINC00909 in SKOV3 cells (a LINC00909-high ovarian cancer cell line) restrained cell proliferation, migration and invasion, and in contrast, overexpression in OVCAR4 cells (a LINC00909-low ovarian cancer cell line) promoted cell migration and invasion.
