The potential of miRNAs as biomarkers for multiple myeloma

摘要

Since the discovery of the link between miRNA and cancer, miRNAs have been investigated in virtually all tumors. Their ability to add a novel level of gene regulation and to target genes apparently not linked to each other has greatly intrigued researchers and physicians alike. In this review, the role of miRNAs in multiple myeloma (MM) is summarized, with particular attention to their potential as biomarkers. The promising role of circulating miRNAs in diagnosis and risk stratification is also discussed, as well as preliminary results of miRNA-based therapeutic approaches. Finally, the critical issues in miRNA analysis in MM and ongoing strategies to solve them are discussed. The ability to standardize miRNA analysis procedures will permit the inclusion of miRNA evaluation alongside available stratification tools, paving the way for personalized medicine in MM.
