Cells were incubated with 5 ng/mL TGF(31 to induce EMT. EMT was confirmed with real-time qPCR, western blot, and immunofluorescence analyses of various EMT markers. Western blot was used to analyze phospho-and total MAPK protein levels. Typical and atypical DUSPs mRNA expression profile was determined by real-time qPCR.Results: The epithelial marker E-cadherin expressions were decreased and mesenchymal EMT markers Snail and Slug expression levels were increased after TGF(31 induction. Phosphorylation of ERK1/2 and p38 MAPK were enhanced in response to TGF(31 treatment. The expression of DUSP2, DUSP6, DUSP8, DUSP10, and DUSP13 were decreased while DUSP7, DUSP16, DUSP18, DUSP21, and DUSP27 were increased by TGF(31.Conclusion: TGF(31 induced EMT which was accompanied by increased activity of MAPKs, and led to marked changes in expressions of several DUSPs in SKOV3 cells.eninfo:eu-repo/semantics/openAccessEpithelial-mesenchymal transitionSpecificity phosphatasesCancerResistanceDual-specificity phosphatasesEpithelial-mesenchymal transitionTgf(31Ovarian carcinomaSkov3MapkScience & technologyLife sciences & biomedicineMedicine, general & internalGeneral & internal medicineArticle00102233470000364064653310.55730/1300-0144.5626
