Mass spectrometry based identification of similarities and differences in protein content of cutaneous melanoma cell lines and exosomes
Ontology highlight
ABSTRACT: Intercellular transport of proteins mediated by extracellular vesicles (EVs) exosomes and ectosomes, is one of the factors facilitating carcinogenesis. Therefore, the research on protein cargo of melanoma-derived EVs may provide a better understanding of mechanisms related to melanoma progression and contribute to development of novel biomarkers. The data concerning the proteome of melanoma-derived EVs is very limited. We used the shotgun nanoLC-MS/MS approach to the profile protein content of primary (WM115, WM793) and metastatic (WM2664, WM1205Lu) cutaneous melanoma cell lines and exosomes. All cell lines secreted homogeneous populations of exosomes enriched in the common set of proteins. A total of 3514 and 1234 unique proteins were identified in melanoma cells and exosomes, respectively. Gene Ontology analysis showed that many of them were involved in cancer cell proliferation, migration, escape from apoptosis, epithelial mesenchymal transition and angiogenesis. The obtained results expand the knowledge about the role of selected proteins in the biology of exosomes, as well as their functional role in the development and progression of cutaneous melanoma. The results might also be used as a starting point for further studies exploring diagnostic and prognostic potential of exosomes.
