VEGFA and lung cancer: Vascular endothelial growth factor (VEGF) is one of the most important factors in angiogenesis and lymphangiogenesis.[35-36] VEGF-A expression level is conversely related to the miR-126 expression level in cancers such as lung cancer.[37] The miR-17-92 cluster is positively associated with angiogenesis in some cancers; however, individual components of the miR-17-92 cluster have opposite effects on angiogenesis.[38-39]
