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. Here, MMP9 is linked to neoplasm.
