Extracellular vesicle DNA from human melanoma tissues contains cancer-specific mutations
Liquid biopsies are promising tools for early diagnosis and residual disease monitoring in patients with cancer, and circulating tumor DNA isolated from plasma has been extensively studied as it has been shown to contain tumor-specific mutations. Extracellular vesicles (EVs) present in tumor tissues carry tumor-derived molecules such as proteins and nucleic acids, and thus EVs can potentially represent a source of cancer-specific DNA. Here we identified the presence of tumor-specific DNA mutations in EVs isolated from six human melanoma metastatic tissues and compared the results with tumor tissue DNA and plasma DNA. Tumor tissue EVs were isolated using enzymatic treatment followed by ultra…
LEMON-DERIVED EXTRACELLULAR VESICLES EXERT ANTI-INFLAMMATORY EFFECTS BY INHIBITING THE ERK/NF-KB PATHWAY
nflammation can be the leading cause of several diseases, including cancer, diabetes, and ulcerative colitis; however, the existing anti-inflammatory drugs cause side effects. For these reasons, it is necessary to find new supportive therapeutic agents. In recent years, plant-derived extracellular vesicles (PDEVs) are gaining increasing interest in the scientific community as they have been found to possess a variety of biological properties; among those, the anti-inflammatory effects have been described by different groups that evaluated the effects of PDEVs in in vitro and in vivo models. We successfully isolated and characterized extracellular vesicles from Citrus limon juice (LEVs) and …
