Fig. 5From: Ougan (Citrus reticulata cv. Suavissima) flavedo extract suppresses cancer motility by interfering with epithelial-to-mesenchymal transition in SKOV3 cellsOFE treatment counteracted TGF-β1-activated SMAD pathways. a The effect of OFE on TGF-β1-induced phosphorylation of SMAD2 and SMAD3 was investigated by western blot analysis in SKOV3 cells. b TGF-β1-induced SMAD pathway activation that resulted in EMT was inhibited by OFEBack to article page
