Dependence on MIWI2 defines two classes of somatic 3’ UTR small RNA clusters. a Expression of Miwi2 in mouse spleen and liver, assayed by quantitative RT-PCR. Results are expressed relative to the level in adult mouse testis; expression is reported on a logarithmic scale, and shows the degree to which it is lower than expression in testis. B and C) Density scatterplots of expression of small RNAs aligning to 3’UTR clusters in wild type mice (x-axis) and MIWI2−/− mice (y-axis) in liver (b) and spleen (c). The intensity of the blue color is proportional to the number of genes with a given level of small RNA expression, measured as log (RPKM); dots in areas of lowest regional density represent individual genes. Plots are generated with smoothScatter in R. A subset of 3’ UTR smRNA clusters is absent in MIWI2−/− mice (bottom, to right of gray line). The gray line separates smRNAs expressed at very low levels
