Three distinctive pre-miRNAs identified in porcine milk exosomes. (A) The ssc-miR-27a precursor produced a 3p-arm miRNA sequence and a loop-derived small RNA. (B) The ssc-let-7e precursor produced a 5p-arm sequence, a 3p-arm miRNA sequence and a loop-derived small RNA. (C) The ssc-miR-30a precursor produced a 5p-arm sequence, a 3p-arm miRNA sequence and a loop-derived small RNA. In addition, ssc-moRNA-3, belonging to new type of miRNA termed moRNA, was found at the 5’ end of pre-miR-30.
