Objective: To investigate the expressions and roles of NF-κB and eIF4E in the endometrial intraepithelial neoplasia(EIN) and endometrioid carcinoma(EC).
Methods:Immunohistochemical SP method was used to detect the expressions of NF-κB and eIF4E in the proliferative stage of endometrium, hyperplasia endometrium, EIN and EC. The statistical data using test were analyzed MannWhitney U test and Wilcoxon. Results: (1) The expression levels of NF-κB increased gradually, and there was no statistically significant difference between EIN and EC(P>0.05). However, difference between the EIN and other groups was significance.(2)The positive rate of eIF4E was significantly higher in EC than in proliferative stage of endometrium,hyperplasia endometrium and EIN(P < 0.05).(3)NF-κB and eIF4E had a strong correlation between EIN and associated lesions(r = - 0.949,P<0.05). Conclusion: NF-κB and eIF4E are highly expressed in EIN and EC. They may be gradually activated in the process of EIN development to EC, and then accelerate transcription or translation,and increase the possibility of endometrial carcinoma.
