The results of Western blotting showed that the levels of adhesion molecules ICAM-1(Intercellular cell adhesion molecular-1), VCAM-1(Vascular cell adhesion molecular-1), and MCP-1(Monocyte chemoattractant protein-1) were upregulated under H2O2-induced oxidative stress, which enhanced the adhesion capacity of HUVECs to THP-1 (Human myeloid leukemia mononuclear cells). The gene discussed is ICAM1; the disease is myeloid leukemia.
