Other studies showed that overexpression of FABP5 promotes cancer metastasis by upregulating matrix metalloproteinase 9 (MMP‐9), a proteolytic enzyme that accelerates tumorigenesis and metastasis, and vascular endothelial growth factor (VEGF), one of the major proteins involved in tumor angiogenesis 28, 31. This evidence concerns the gene FABP5 and neoplasm.
