title: Functional linc-POU3F3 is overexpressed and contributes to tumorigenesis in glioma.
abstract: Growing number of long intergenic noncoding RNAs (lincRNAs) have recently been identified in mammals as new modulators in cancer origination and progression involved in a broad range of biological processes. Long intergenic noncoding RNA POU3F3 (linc-POU3F3) has been characterized as a highly conserved functional transcription regulator in esophageal squamous cell carcinoma. The contributions of this lincRNA to glioblastoma remain unknown. In this present study, we investigated the expression pattern and functional role of linc-POU3F3 in glioma by using real-time PCR and gain-/loss-of-function studies. The results revealed that linc-POU3F3 levels were extraordinarily associated with the tumor WHO grade. In related biochemical assays, overexpression of linc-POU3F3 promotes cell viability and proliferation in glioma cells, whereas knockdown of linc-POU3F3 showed the opposite effect. As expected, we also found that linc-POU3F3 expression was negatively correlated with the mRNA level of POU3F3 (the evolutionarily conserved neighbor gene of linc-POU3F3). Our results indicate that linc-POU3F3 might affect glioma development via altering expression level of POU3F3, and lead us to believe that linc-POU3F3 may also have a crucial regulatory role in glioma progression.
