In our preliminary experiment with NPC cell derived xenografts, LBH overexpression in NPC cells led to inhibited neovascularity and downregulation of CRYAB and VEGFA in harvested xenografts, and LBH protein colocalized with vesicle biomarkers in NPC cells, suggesting potential LBH secretion via exosomes. This evidence concerns the gene LBH and nasopharyngeal carcinoma.
