NANOG and ovarian cancer: FOXP1 upregulates the transcriptional activities of four key stemness factors, ATP Binding Cassette Subfamily G Member2 (ABCG2), octamer-binding transcription factor 4 (OCT4), nanog homeobox (NANOG) and SOX2, to promote CSCs-like features in ovarian cancer cells (Choi et al., 2016).
