MiR-205 expression promotes cell proliferation and migration of human cervical cancer cells.

ABSTRACT: MicroRNAs (miRNAs) are short non-coding RNA regulators that control gene expression mainly through post-transcriptional silencing. We previously identified miR-205 in a signature for human cervical cancer using a deep sequencing approach. In this study, we confirmed that miR-205 expression was frequently higher in human cervical cancer than their matched normal tissue samples. Functionally, we demonstrate that miR-205 promotes cell proliferation and migration in human cervical cancer cells. To further understand the biological roles of miR-205, we performed in vivo crosslinking and Argonaute 2 immunoprecipitation of miRNA ribonucleoprotein complexes followed by microarray analysis (CLIP-Chip) to identify its potential mRNA targets.
