Abstract
MiRNAs are non-coding single-stranded RNAs comprised of 20-22 nucleotides and considered as a novel class of gene regulators. It has been suggested that miRNA expression correlates with classification of various cancers. About half of the annotated human miRNAs are located in fragile sites of the genome suggesting that these small molecules might have a vital function in cancer progression. miRNAs can regulate gene expression transcriptionally or translationally. There is an emerging evidence that miRNAs are involved in cancer pathogenesis. A number of studies have detected frequent alterations of miRNA expression in a variety of human malignancies including prostate cancer. We have recently demonstrated a widespread deregulation of miRNA expression in human prostate cancer. The status of the selected miRNAs, in human prostate cancer cell lines DU-145, LNCaP, LAPC4, PC3 and prostate cancer specimens have been analyzed. We have transfected these cell lines with precursor miR- and anti miR- molecules and compared the gene expression profiles. We have also compared the targets for these selected miRNAs identified biologically in prostate cancer cells and in three different databases. The expression status of select- targets have been verified and the biological effects of these targets on prostate cancer cell lines are studied. The results obtained in these studies demonstrate that microRNA(s) can be used to find new markers for prostate cancer progression and to define promising targets for prostate cancer therapy.
