MicroRNAs as new biomarkers in oncology

Research output: Contribution to journalArticlepeer-review


MicroRNAs (miRNAs) represent a new class of small non-coding RNAS ∼ 22 nucleotides in length that are involved in fine-tuning of gene expression. An increasing number of papers are identifying a link between miRNAs and cancer. The discovery of miRNA expression signatures able to discriminate tumor from normal cells and between various categories of patients with the same type of cancer suggests the possible application of miRNAs as new biomarkers in molecular oncology. In this review, the authors describe the different techniques used to detect miRNAs in tumor samples and their potential for clinical use. The authors review the published evidence testing miRNAs as novel cancer biomarkers and describe the steps necessary to move forward in the application of miRNAs as biomarkers. Finally, the authors consider the utility of miRNAs as tumor predisposition markers in cancer screening programs.
