The Role of the Exonic lncRNA PRKDC-210 in Transcription Regulation.

ABSTRACT: In recent years, long noncoding RNAs (lncRNAs) have received increasing attention and have been reported to be associated with various genetic abnormalities. However, the functions of many lncRNAs, including those of long exonic noncoding RNAs (lencRNAs), have not yet been elucidated. Here, we used a novel tethering luciferase assay to analyze the transcriptional regulatory functions of five lencRNAs that are upregulated in cancer. We found that the lencRNA PRKDC-210 interacts with MED12, a component of the CDK8 complex, to regulate the transcription of several genes. The transcriptional activation ability of PRKDC-210 was abolished in siRNA-treated CDK8-depleted cells. We also confirmed the enrichment of PRKDC-210 on RNA polymerase II.
