GEPIA website analysis showed that the expression of TMEFF1 mRNA was significantly increased in ovarian cancer, uterine corpus endometrial carcinoma, and uterine carcinosarcoma, but decreased in glioblastoma multiforme, acute myeloid leukemia, and thyroid carcinoma (Fig. 1B). This evidence concerns the gene TMEFF1 and uterine carcinosarcoma.
