Next generation sequencing of small RNAs isolated from exosomes in human semen


ABSTRACT: Preparation of exosomes isolated from semen contain a substantial amount of RNA, mostly from 20 to 100 nucleotides in length. We sequenced separately 20-40 and 40-100 nucleotide fractions of RNA from exosomes isolated from semenal fluid from six healthy donors. We found various classes of small non-coding RNA, including mature microRNA and piwi-RNA, as well as abundant Y RNAs and tRNAs present in both full length and fragmented forms. Specific RNAs were consistently present in all donors. For example, fifteen (of ~2,600 known) microRNAs constituted over 80% of mature microRNA in SE. Additionally, tRNA fragments were strongly enriched for 5M-bM-^@M-^Y-ends of 18-19 or 30-34 nucleotides in length.

Semen contains relatively ill-defined regulatory components that likely aid fertilization, but which could also interfere with defense against infection. Each ejaculate contains trillions of exosomes, membrane-enclosed subcellular microvesicles, which have immunosuppressive effects on cells important in the genital mucosa. Exosomes in general are believed to mediate inter-cellular communication, possibly by transferring small RNA molecules. We found that seminal exosome (SE) preparations contain  ...[more]
