These results indicated that ICAM‐1 and ESM1 were upregulated by IH via the IH‐induced downregulation of miR‐181a1 in vascular endothelial cells and suggested that SAS patients developed atherosclerosis via the IH‐induced upregulation of ICAM‐1 and ESM1. The gene discussed is ICAM1; the disease is atherosclerosis.
