The inhibition of tumour proliferation is a property that has been described in the literature for several classes of flavonoids, and studies have shown the potential of flavonoids in regulating molecules associated with tumour cell migration, such as matrix metalloproteinases (MMPs), TGF-β, and vascular endothelial growth factor (VEGF), among others [20,21,22,23]. Here, TGFB1 is linked to neoplasm.
