LTF and endometrial endometrioid carcinoma: Intestinal trefoil protein, TFF3, AGR2 developmental gene, estrogen-regulated genes (MGB2, LTF, END1, MMP11), FOXA2, and MSX2 were significantly up-regulated in endometrioid endometrial carcinomas, while increased expression of FOLR, genes involved in the regulation of mitotic spindle checkpoint (STK15, BUB1, CCNB2), IGF2, PTGS1 and p16 were seen in non-endometrioid endometrial carcinomas.
