Conflict of interest statement

Dr. Slack reports holding two pending patents for the use of microRNAs as potential therapeutic and diagnostic markers in cancer, and Dr. Weidhaas, two pending patents for the use of microRNAs in predicting the risk of ovarian cancer and response to chemotherapy. No other potential conflict of interest relevant to this article was reported.

Figures

Figure 1.
Figure 1.. Drosha and Dicer and the Processing and Function of MicroRNA (miRNA).
Pri-miRNAs, large miRNA precursors, are transcribed from the genome by RNA polymerase II and fold into a hairpin structure that is the substrate for RNA processing by Drosha (cleavage sites shown as dark red arrows) to a pre-miRNA. Pre-miRNAs enter the cytoplasm, where they are further processed by Dicer (and its partner, Loqs–TRBP), resulting in an RNA duplex containing the mature miRNA and the miRNA star sequences. The mature miRNA preferentially enters the miRNA-associated, multiprotein RNA–induced silencing complex (miRISC) and guides it to partially complementary sequences in target messenger RNA (mRNA), leading to repression of their translation. AAAA represents the poly-A tail, and MGpppG denotes the 5′ cap. ORF denotes open reading frame, Ran-GTP Ran guanosine triphosphate, and UTR untranslated region.
