Furthermore, using a set of ovarian cancer cell lines, we have shown that during the reactivation of epithelial genes, the presence of GRHL2 is essential for the modification of the epigenetic landscape into a permissive chromatin to allow the transcription of key epithelial genes such as E-cadherin, ESRP1 and OVOL2 (Chung et al., 2019). This evidence concerns the gene OVOL2 and ovarian carcinoma.
