For instance, EBERs regulate the expression of vascular cell adhesion molecule 1 (VCAM-1) through TLR3/RIG-I to induce angiogenesis 47; EBV-miR-BART10-5p and miR-18a strongly promote angiogenesis and tumor growth of NPC by mediating the expression of VEGF and HIF1-α in a Spry3-dependent manner 48. The gene discussed is HIF1A; the disease is nasopharyngeal carcinoma.
