Abstract

MicroRNAs (miRNAs) are short regulatory RNAs that negatively modulate protein expression at the post‑transcriptional level. Additionally, they have been associated with the pathogenesis of a number of types of cancer. In the current study, two target sites for miR‑150 were determined within the 3'‑untranslated region of p27Kip1 (hereafter referred to as p27) mRNA, and it was determined that ectopic overexpression of miR‑150 led directly to p27 downregulation in cancer cells. These findings indicate that miR‑150 may be a novel regulator of p27 expression. In the databases of the University of California, Santa Cruz (UCSC) and Match online, two common transcription factors were identified for miR‑150 and p27: Cooperates with myogenic proteins 1 (COMP1) and hepatocyte nuclear factor‑4 (HNF‑4). Using the Database for Annotation, Visualization, and Integrated Discovery (DAVID), it was determined that p27 is involved in pathways regulated by the target genes of miR‑150. Therefore, these results suggest that there may be a regulatory loop between COMP1 and HNF‑4‑miR‑150‑p27. Additional functional studies are required to understand the molecular basis for the formation of this circuit loop, and provide an insight into the development of innovative therapies targeting specific tumor markers.
