FOXE1 and thyroid cancer: These observations, together with the genetic studies associating SNPs in and near the FOXE1 locus with thyroid cancer risk, and the altered expression of FOXE1 (Landa et al. 2009, He et al. 2015a, Wang et al. 2017), have motivated us to further investigate the role of FOXE1 in thyroid cancer, to try to better understand the dual role of this transcription factor as both a differentiation and a tumoral factor.
