Paralog clusters miR17/92-1, miR25/106b, and miR363/106a are overexpressed in centroblasts. (A-C) Log ratio values are plotted. Only miRNAs that are the main processed product of the corresponding pre-miRNA and with no more than 3 missing values in the microarrays were included. Dashed lines are used to represent miRNAs not included in the 39 miRNA cell-of-origin classifiers.
