Melanoma is the most aggressive skin cancer and responsible for majority of deaths. Despite advances in treatment, our current prognostic indicators are poor fail to adequately risk-stratify patients. This study evaluates concentration, size, proteomic metabolomic profile circulating extracellular vesicles (EVs) isolated from plasma patients with melanoma, identify potential biomarkers disease ...

Background and Aims: During vascular calcification (VC), a cardiovascular complication of atherosclerosis, smooth muscle cells (VSMCs) undergo an osteogenic switch secrete heterogeneous population extracellular vesicles (EVs) involved in inflammation oxidative stress. The objective our study is to determine the role mechanism action EVs propagation stress during VC.

Dictyostelium discoideum microvesicles have recently been presented as a valuable model for eukaryotic extracellular vesicles. Here, the advantages of D. discoideum for unraveling important biological functions of extracellular vesicles in general are detailed. D. discoideum, a non-pathogenic eukaryotic microorganism, belongs to a billion-year-old Amoeboza lineage, which diverged from the anima...

Treatment of BRAF mutant melanoma with kinase inhibitors has been associated with rapid tumor regression; however, this clinical benefit is short-lived, and most patients relapse. A number of studies suggest that the extracellular environment promotes BRAF inhibitor resistance and tumor progression. Extracellular vesicles, such as exosomes, are functional mediators in the extracellular environm...
