Additional file 5: Figure S3. of Differential expression of estrogen receptor subtypes and variants in ovarian cancer: effects on cell invasion, proliferation and prognosis

Overexpression of ERβ2 increased ovarian cancer cell migration and invasion. (a) Immunoblot analyses of exogenous His-tagged ERβ2 in TOV-21G cells stably transfected with His-tagged ERβ2 or control vector. (b) In vitro migration and invasion assays in TOV-21G cells overexpressing ERβ2. Upper panel: representative images of migrating or invading cells. Lower panel: Cell migration or invasion presented as percentage of control; n = 3; *, p < 0.05. (PDF 223 kb)
