Popis: The 5-year survival rate is very low when breast cancer becomes metastatic. The metastatic process is governed by a network of molecules of which SLUG is known to play a major role as a regulator of epithelial-to-mesenchymal transition (EMT). Prostate-derived ETS factor (PDEF) has been proposed as a tumor suppressor, possibly through inhibition of invasion and metastasis; therefore, understanding the mechanism of PDEF regulation may help to better understand its role in breast cancer progression. This study shows for the first time that the transcription factor SLUG is a direct target of PDEF in breast cancer. We show that the expression of PDEF is able to suppress/dampen EMT through the negative regulation of SLUG. In addition, we show that PDEF is also able to regulate downstream targets of SLUG, namely E-cadherin, in both SLUG-dependent and -independent manners, suggesting a critical role for PDEF in regulating EMT.
