Compared with normal endometrial epithelial cell line hEEC, the expression levels of NSUN2, NUDT3 and LARP1 in human endometrial carcinoma cell line HEC-1A were significantly increased (P < 0.001), while the expression levels of NCBP3 were significantly decreased (P < 0.001), further supporting the conclusion of the above analysis (Fig. 11). Here, NSUN2 is linked to endometrial carcinoma.
