Interestingly, LOXL2 has also been found in proteomic analysis of extracellular vesicles of squamous carcinoma cells 30 and human umbilical vein endothelial cell (HUVEC)‐derived exosomes 31, and both LOXL2 and LOX were found in exosomes isolated from glioblastoma cells 32, 33. This evidence concerns the gene LOXL2 and glioblastoma.
