ABSTRACT
Objective:To detect the expression of acetaldehyde dehydrogenase (ALDH) 2 and microRNA (miR)-135b-3p in endometrial cancer (EC) tissues, and to explore their correlation with clinical characteristics.Methods:94 endometrial cancer tissue specimens (EC group) and 60 normal endometrial specimens (control group) were selected from Northwest Women′s and Children′s Hospital from February 2019 to February 2022. Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression changes of ALDH2 mRNA and miR-135b-3p in endometrial tissue of two groups, and immunohistochemistry was used to detect the positive expression rate of ALDH2 protein. The relationship between the expression levels of ALDH2 and miR-135b-3p and the clinicopathological characteristics was analyzed.Results:The expression of ALDH2 mRNA in the EC group (0.67±0.15) was lower than that in the control group (1.05±0.12), and the expression level of miR-135b-3p (1.52±0.26) was higher than that in the control group (1.01±0.06). The positive expression rate of ALDH2 in cancer tissue of EC group was 30.85%(29/94), which was lower than 51.67%(31/60) in normal endometrial tissue of the control group ( P<0.05). The expression levels of ALDH2 mRNA and miR-135b-3p in EC patients were related to International Federation of Obstetrics and Gynecology (FIGO) stage, lymph node metastasis, differentiation and myometrium invasion (all P<0.05), but not to age, pathological type, menopause, HPV infection, menarche age, parity, tumor length and BMI (all P>0.05). Conclusions:In EC tissues, the expression of ALDH2 is down-regulated and the expression of miR-135b-3p is up-regulated, which may be involved in the occurrence and development of EC.
