Our analysis of FOXE1 expression in a panel of thyroid cancer cell lines shows that FOXE1 levels inversely correlate with differentiation degree according to histological sub-type origin of cell lines, which is consistent with data on the expression patterns of FOXE1 in PTC and normal tissues by TCGA and fits with data of FOXE1 expression in a genome array of human tumors that include all histological variants (Giordano et al. 2006). Here, FOXE1 is linked to thyroid gland carcinoma.
