Dataset Summary
TitleSupermeres in breast and pancreatic cancer cells
DescriptionExtracellular vesicles, including exosomes, and exomere nanoparticles, are under intense investigation for cargo that may serve as clinical biomarkers or therapeutic targets. Here, we report discovery of a new extracellular nanoparticle, termed supermeres. We performed LC/MS-MS proteomics analyses on gradient-purified sEVs, NVs, exomeres and supermeres. The proteomic profile of supermeres is clearly distinct from that of sEVs, NVs and exomeres. This study identifies a new functional nanoparticle replete with potential circulating biomarkers and therapeutic targets that can be exploited for clinical benefit in a host of diseases.
