Expression of dual-specifiicity phosphatases in TGFss1-induced EMT in SKOV3 cells

Background/aim: The study aims to profile the dual-specificity phosphatases (DUSP) expression in response to Transforming growth factor (31 (TGF(31)-induced epithelial-mesenchymal transition (EMT) in ovarian adenocarcinoma cells.Materials and methods: The ovarian adenocarcinoma cell line SKOV3 was used as a TGF(31-induced EMT model. 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.

Automated summary

The study aims to profile the expression of dual-specificity phosphatases (DUSPs) in ovarian adenocarcinoma cells undergoing epithelial-mesenchymal transition (EMT) induced by Transforming growth factor (TGF)β1. TGF(31) treatment decreased E-cadherin expression and increased expression of EMT markers Snail and Slug. The activation of MAPKs was enhanced and the expression of certain DUSPs was altered in response to TGF(31).
