Popis: Abstract The ubiquitin conjugating enzyme E2 N (UBE2N) has been reported to be involved in the tumorigenesis of several tumors, but its function in cervical carcinoma has not been investigated yet. In the present study, UBE2N was found elevated in cervical carcinoma, and patients with high UBE2N had a shorter overall survival than patients with low expression. Additionally, knockdown of UBE2N decreased the activation of MEK1/2 and p38 in cervical carcinoma cells, and UBE2N knockdown also markedly inhibited cervical carcinoma cell growth. Our further studies found that microRNA‐590‐3p (miR‐590‐3p) was significantly decreased in cervical carcinoma, and patients with high miR‐590‐3p had a longer overall survival than patients with low expression. Moreover, miR‐590‐3p expression was found negatively correlated with UBE2N expression in cervical carcinoma, and our further studies showed that miR‐590‐3p targeted UBE2N and inhibited its expression in cervical carcinoma. Overexpression of miR‐590‐3p could inhibit cervical carcinoma cell growth, but enhanced UBE2N could rescue miR‐590‐3p‐induced cell growth inhibition in cervical carcinoma. This study indicated that targeting miR‐590‐3p/UBE2N axis could be a potential strategy for the treatment of cervical carcinoma.
