Expanding on previous demonstrations of the therapeutic effects of adeno‐associated virus (AAV) carrying small‐hairpin RNA (shRNA) in downregulating the mechanistic target of rapamycin (mTOR) in in vivo retinal vascular disorders, vascular endothelial growth factor (VEGF)‐stimulated endothelial cells were treated with AAV2‐shmTOR to examine the role of mTOR inhibition in retinal angiogenesis. This evidence concerns the gene MTOR and retinal vascular disorder.
