Figure 6. Comparison of RNA binding motifs on exosomal lncRNAs versus cellular transcripts.

(A) Reduction of RBP motifs in cellular lncRNAs which are common to all four cell lines. In contrast there is a increase of these motifs in the exosomal lncRNAs. (B) Increase in RBP motifs of the enriched exosomal lncRNAs (141 transcripts) to those lncRNAs, which were highly expressed in the cells (151 transcripts) of at least one cell line. This analysis yielded four major binding sites for, RBMX, SFRS1, SFRS9 and EIF4B.
