Expression of miRNA families. (A) Expression of the let-7f family; let-7f-1, let-7a and let-7d formed a cluster, while miR-98 and let-7e formed a cluster. (B) Expression of miR-30 family; miR-30d clustered with miR-30b, and miR-30c clustered with miR-30e. (C) Expression of miR-181 family; miR-181a clustered with miR-181b, and miR-181c clustered with miR-181d. (D) MiR-222 and miR-221; miR-222 and miR-221 belonged to the same family and the same cluster. (E) MiR-27 family and miR-23 family; miR-27b and miR-23b formed a cluster in the genome. (F) Expression and clustering of remaining miRNA families; members 1, 2, 3 and 4 represent members of the indicated family. (G) Novel miRNA family with low expression. (H) Expression of the miR-148 family containing milk “marker” miRNAs.
