Overexpression of ERβ dysregulates EMT, JAK/STAT3, ROS, and angiogenesis signaling in human endometrial cells. (A) Expression profile of genes involved in EMT signaling in IHEECs vs EBO-IHEECS determined by Western blot. (B-D) Expression profiles of SOCSs (B), levels of H2O2 (C), and proangiogenic factors (D) in IHESCs, EBO-IHESCS, IHEECs, and EBO-IHEECs determined by Western blot or luciferase activity. VEGF, vascular endothelial growth factor.
