| الوصف: | Abstract Extracellular vesicles (EVs) play a critical role in the transport of functional RNAs to target recipient cells in numerous physiological processes. The RNA profiles present in EVs differed significantly from those in the originating cells, suggesting selective and active loading of specific RNAs into EVs. Small EVs (sEVs) obtained by stepwise ultracentrifugation have been reported to contain non-sEV components. Analysis of sEVs separated from non-sEVs components revealed that microRNAs may not be released by sEVs. This has raised interest in other RNA types, such as mRNA, which may be functional molecules released by sEVs. However, the molecular mechanisms underlying selective loading of mRNA into sEVs remain unclear. Here, we show that the part of 3′ untranslated region (UTR) sequence of RAB13 selectively enriches RNA in sEVs and serves as an RNA signal for loading into sEVs. Our results demonstrate that RAB13 is the most enriched RNA in sEVs, and this enrichment is primarily driven by its 3′UTR sequence. These findings highlight the potential of the RAB13 3′UTR sequence as an RNA signal that enables the loading of target RNA into sEVs. This technology has the potential to improve EV-based drug delivery and other applications. |
