The roles of microRNA (miRNA/miR)-383-5p have been reported in several malignancies, including breast cancer, gastric cancer, ovarian cancer and lung adenocarcinoma. However, its function in diffuse large B-cell lymphoma (DLBCL) remains unclear. Thus, the present study aimed to investigate the role of miR-383-5p in DLCBL. Reverse transcription-quantitative PCR analysis was performed to detect miR-383-5p expression in 80 paired tissue samples from patients with DLBCL and control subjects, as well as related cancer cell lines. Kaplan-Meier survival analysis was performed, and the prognostic value of miR-383-5p was determined via Cox regression analysis. Furthermore, the association between miR-383-5p expression and the clinicopathological characteristics of patients with DLBCL was investigated. The Cell Counting Kit-8, crystal violet staining and Transwell assays were performed to assess the effects of miR-383-5p on cell proliferation and invasion, respectively. The results demonstrated that miR-383-5p expression was upregulated in human DLBCL tissues and cell lines. In addition, miR-383-5p expression was closely associated with clinical stage and extranodal invasion in patients with DLBCL. Notably, high miR-383-5p expression was able to predict a favorable clinical prognosis in patients with DLBCL. Furthermore, overexpression of miR-383-5p significantly inhibited the proliferation and invasion of DLBCL cells, the effects of which were reversed following miR-383-5p knockdown. T...
