TET2 expression among different histopathological samples (Endometrioid endometrial adenocarcinoma, Serous endometrial adenocarcinoma, Mixed serous and endometrioid) from TCGA public database showed that the expression of TET2 was also significantly different among different histopathological samples, and it was significantly over-expressed in Endometrioid endometrial adenocarcinoma (Figure 1B). Here, TET2 is linked to endometrium adenocarcinoma.
