As Kore et al. found that hypoxic exosomes derived from GBM cells selectively elevated some proteins such as protein-lysine 6-oxidase (LOX), thrombospondin-1 (TSP1) and vascular derived endothelial factor (VEGF), which were known to be associated with tumor progression, metastasis and angiogenesis [35]. The gene discussed is VEGFA; the disease is neoplasm.
