VEGFA and ovarian carcinoma: VEGFA is a well‐characterized growth and survival factor for vascular endothelial cells that is overexpressed in a wide range of tumours, including ovarian cancer.30 VEGFA can enhance cell invasion by inducing angiogenesis and activating matrix metalloproteinases31 and increase cell viability.32 Moreover, VEGFA can also protect against apoptosis in renal clear cell carcinoma.33 A number of anti‐VEGF therapies exist and have been proposed for ovarian cancer.34 Therefore, study of the mechanisms that regulate VEGFA is important.
