Abstract:
Objective To investigate the relationship between the expression of miR-141-3p,miR-149-3p and proliferative genes,clinicopathological features and prognosis in endometrial carcinoma tissues.Methods From February 2017 to February 2019,98 patients with endometrial cancer were selected as the study objects.Real-time fluorescence quantitative PCR was used to detect the relative mRNA expression levels of miR-141-3p,miR-149-3p and proliferating genes[proliferating cell nuclear antigen(PCNA),cyclin D1,cyclin dependent kinase 4(CDK4)]in cancer tissues of patients with endometrial cancer.The correlation between the expres-sions of miR-141-3p,miR-149-3p and PCNA,cyclin D1 and CDK4 mRNA in cancer tissues of patients with en-dometrial cancer was analyzed by Pearson correlation analysis.The expression of miR-141-3p and miR-149-3p in cancer tissues of endometrial carcinoma patients with different clinicopathological characteristics was com-pared.Kaplan-Meier curve was used to analyze the influence of miR-141-3p and miR-149-3p expression on prognosis of patients with endometrial carcinoma.Univariate and multivariate Cox regression analysis of prog-nostic factors in patients with endometrial cancer.Results The relative expression levels of miR-141-3p,miR-149-3p,PCNA mRNA,cyclinD1 mRNA and CDK4 mRNA in cancer tissues of patients with endometrial carci-noma were higher than those in adjacent tissues,with statistical significance(P＜0.05).The expressions of miR-141-3p and miR-149-3p were positively correlated with the expressions of PCNA mRNA,cyclinD1 mR-NA and CDK4 mRNA in cancer tissues of patients with endometrial carcinoma(all P＜0.05).The relative ex-pression levels of miR-141-3p and miR-149-3p in cancer tissues of endometrial cancer patients with stage Ⅲand lymph node metastasis according to International Federation of Gynecology and Obstetrics(FIGO)were higher than those of endometrial cancer patients with stage Ⅰ-Ⅱ and no lymph node metastasis,respective-ly,and the difference was statistically significant(P＜0.05).The 3-year overall survival rate of miR-141-3p high expression group was significantly lower than that of miR-141-3p low expression group,and the differ-ence was statistically significant(Log-rank x2=7.043,P=0.008).The 3-year overall survival rate of patients with high miR-149-3p expression group was significantly lower than that of patients with low miR-149-3p ex-pression group,with statistical significance(Log-rank x2=7.094,P=0.007).FIGO stage Ⅲ,lymph node me-tastasis,miR-141-3p elevation and miR-149-3p elevation were independent risk factors for prognosis of pa-tients with endometrial cancer(P＜0.05).Conclusion Detecting the expression of miR-141-3p and miR-149-3p in cancer tissues of patients with endometrial carcinoma is helpful to evaluate the survival and prognosis of patients.
