Examples of new miRNAs discovered. Plots show the number of reads per nucleotide position mapping in extended hairpin loci for hsa-mir-1307, hsa-mir-376a-2, hsa-mir-382, and hsa-mir-539, expressing both known and new miRNAs. Known miRNA position respective to the extended hairpin is indicated in the plot. In the top part of panel, the sequence of mature miRNAs is shown (red indicates known miRNA; and pink, new miRNA).
