Inhibition of extracellular vesicle-derived miR-146a-5p decreases the progression of melanoma brain metastasis in vitro and in vivo
Ontology highlight
ABSTRACT: Development of melanoma brain metastasis is caused by an interaction between tumor cells and normal cells in the brain microenvironment. miRNAs delivered by exosomes derived from the tumor cells seem to prime the brain microenvironment, prior to extravasation of tumor cells into the brain. We investigated miRNA in exosomes extracted from normal (astrocytes, melanocytes) and metastatic melanoma cells (brain, skin and lymph node metastasis). We have discovered that miR-146a-5p is an important player in brain metastatic development: this miRNA was highly upregulated in exosomes from melanoma brain metastasis cells, compared to normal cells.
