VEGFA and neoplasm: CoREST1 knockdown resulted in striking changes in the tumor cell conditioned media including notable decreases in levels of secreted pro-angiogenic factor vascular endothelial growth factor A (VEGF-A), pro-inflammatory factors CCL2/MCP-1 and CXCL16, as well as anti-angiogenic factor thrombospondin 1 (TSP1) compared to conditioned media from control cells (Fig. 3A, B).
