VEGFA and head and neck cancer: Amyloid precursor protein (APP) acetylation and induction of apoptosis in human neuroblastoma, modulation of β-catenin activity and inhibition of head and neck cancer cell proliferation, rise in level of reactive oxygen species (ROS) with activation of caspase-3 and lowering the expression of vascular endothelial growth factor (VEGF) in esophageal squamous cells are some of the pathways for EECG’s anticancer action [53–55].
