    Abstract

    MicroRNAs (miRNAs) are a novel class of small endogenous non-coding RNAs that regulate gene expression post-transcriptionally by binding to their cognate target mRNAs. Emerging evidence implies that miRNAs play important roles in cancer and thus, miRNAs have rapidly emerged as valuable markers for cancer diagnostics and promising targets for therapeutics. Locked nucleic acid (LNA) is a conformational RNA analoque that binds complementary RNA with unprecedented affinity and specificity. These properties make LNA well suited for miRNA detection and analysis for cancer diagnostics. Furthermore, recent studies on LNA-mediated silencing of miRNA function in vitro and in vivo support the potential of LNA in therapeutic intervention of cancer-associated miRNAs.
