Abstract/OtherAbstract:
The miR-17-92 cluster is composed of seven miRNAs (microRNAs; miR-17-5p, miR-17-3p, miR-18a, miR-19a, miR-20a, miR-19b-1 and miR-92a-1). Previous studies have indicated that this cluster is involved in cell proliferation and their overexpression has been seen in several types of cancer. We have assessed the overexpression effects of miR-17-92 on the expression of several genes associated with cell-cycle regulation. The human miR-17-92 gene was cloned into a transposone-based vector, piggyBac and transfected into HEK-293T [HEK-293 cells (human embryonic kidney cells) expressing the large T-antigen of SV40 (simian virus 40)] cell line. Gene expression analysis indicated that up-regulation of this cluster causes significant changes in the expression of several cell-cycle related genes, including CDK2 (cyclin-dependent kinase 2), cyclin-D2, c-Myc and CREB (cAMP-response-element-binding protein). Other methods of transcripts assessment confirmed miR-17-92 overexpression enhances cell proliferation.
