Aim: PR-domain-containing 5 (PRDM5), a family member of PR-domain-containing zinc finger genes, has been reported to participate in modulate cellular processes, including cell growth, differentiation and apoptosis. It has also been found to function as a putative tumor suppressor in different types of cancer. The present study is the first, to the best of our knowledge, to report on the clinical significance of the expression of PRDM5 in glioma cell line.Materials and Methods: Western blot analyse the expression of PRDM5 in glioma tissues and cells. 80 tissues microarray samples from patients with glioma were examined using immunohistochemical analysis. Glioblastoma U251 cells were transfected with PRDM5-siRNA and control-siRNA. U251cell proliferation was measured by flow cytometric analysis and plate colony formation assay. Cell apoptosis were detected using flow cytometric analysis.Results: The results of western blot analysis and immunohistochemistry showed that the expression of PRDM5 was decreased in fresh glioma tissues, compared with that in normal brain tissues. Kaplan-Meier postoperative survival curves demonstrated that the low expression of PRDM5 was associated with poor prognosis in patients with glioma. In addition, suppression of PRDM5 promoted cell proliferation via regulating cell cycle progression. Finally, knocking down PRDM5 using small interfering RNA decreased the apoptosis of glioma cells.Conclusion: Taken together, these findings suggested that PRDM5 may be a novel therapeutic target of glioma.
