The transcription factor Snail is considered as an important regulator of tumor invasiveness due to its estrogen receptor-regulated inhibitory action on the cell adhesion molecule E-cadherin. The aim of this work was to analyze for the first time the active, i.e. nuclear localized, Snail protein in 211 tissue samples of human gynaecological cancers, including endometrial and ovarian cancers. In addition, cell culture-based functional analyses were performed. My results indicate that Snail is associated with tumor progression in endometrial cancer and lower overall survival of ovarian cancer patients. However, the proposed regulation of Snail through estrogen receptor α signaling could not be confirmed in vitro.
