In the course of studying crosstalk between inflammation and angiogenesis, high doses of pro-inflammatory factors have been reported to induce apoptosis in cells. Under normal circumstances also the pro-inflammatory cytokines are being released in low doses and are actively involved in cell signaling pathways. We studied the effects of low grade inflammation in growth factor induced angiogenesis using tumor necrosis factor alfa (TNFα) and vascular endothelial growth factor A (VEGF) respectively. We found that low dose of TNFα can inhibit VEGF induced angiogenesis in human umbilical vein endothelial cells (HUVECs). Low dose of TNFα induces mild upregulation and moreover nuclear localization of tumor suppressor protein 53 (P53) which causes decrease in inhibitor of DNA binding-1 (Id1) expression and shuttling to the cytoplasm. In absence of Id1, HUVECs fail to upregulate β3-integrin and cell migration is decreased. Connecting low dose of TNFα induced p53 to β3-integrin through Id1, we present additional link in cross talk between inflammation and angiogenesis. •Low grade inflammation (low dose of TNF alfa) inhibits VEGF induced endothelial cells migration.•The low grade inflammation with VEGF treatment upregulates P53 to a nonlethal level.•P53 activation inhibits Id1 shuttling to the cytoplasm in endothelial cells.•Inhibition of Id1 resulted in downregulation of β3-integrin which cause decrease in cell migration.•Inflammation and angiogenesis might cross-talk by P53 – Id1 – β3-integrin pathway in endothelial cells.
