Four CNV candidate regions located in AMD-relevant genes (VEGFA, ARMS2/HTRA1, CFH and VLDLR), were selected based on the outcomes of our previous study which elucidated common CNVs in the Asian populations.
Furthermore, VEGF is involved in the development and growth of cancer and other diseases like agerelated macular degeneration, rheumatoid arthritis, diabetes mellitus, and neurodegenerative disorders.
Furthermore, LV-delivered microRNAs targeting the Vegfa gene in RPE cells reduced the size of laser-induced CNV in mice 28 days PI, as a consequence of diminished VEGF levels, suggesting that LVs delivered locally are powerful tools in the development of gene therapy-based strategies for treatment of age-related macular degeneration (AMD).

Genotypes of 3 polymorphisms in known AMD susceptibility loci (rs1061170 in complement factor H (CFH), rs11200638 in HTRA1 and rs1413711 in VEGF) were determined.
Genotypes of polymorphisms in known AMD susceptibility loci (CFH, CFB, HTRA1, AMRS2, and VEGFA) as well as not yet reported AMD-associated genes (KDR, LRP5, and FZD4) were determined, and their frequencies were compared.
Here we show that mice lacking c-Jun N-terminal kinase 1 (JNK1) exhibit decreased inflammation, reduced CNV, lower levels of choroidal VEGF, and impaired choroidal macrophage recruitment in a murine model of wet AMD (laser-induced CNV).
Here we show that sFLT-1, an endogenous inhibitor of vascular endothelial growth factor A (VEGF-A), is synthesized by photoreceptors and retinal pigment epithelium (RPE), and is decreased in human AMD.
Here, we describe a deep sequencing-aided engineering strategy to fine-tune the specificity of an angiopoietin-2 (Ang2)/vascular endothelial growth factor (VEGF) dual action Fab, 5A12.1 for the treatment of age-related macular degeneration.
However, whether or not VEGF is indeed critical for the pathogenesis of subretinal neovascularization (SRN) in adulthood, which is a serious complication of age-related macular degeneration, has to be further investigated.
In conclusion, the presented data reveal that gene therapy targeting VEGFA via multigenic AAV vectors displays combined efficacy, suggesting that dual-acting therapy is an important tool in future eye gene therapy for the treatment of neovascular ocular diseases, including AMD.
In December 2004, the US Food and Drug Administration approved the first aptamer-based therapeutic, pegaptanib (Macugen), targeting vascular endothelial growth factor, for the treatment of age-related macular degeneration.
In our work, we searched for an association between the -460C> (rs833061) and -634G>C (rs2010963) polymorphisms of the VEGF gene and the occurrence of AMD and its dry and wet forms.
In the present study, we tested the hypothesis that VEGF gene polymorphisms play a role in the treatment success with VEGF inhibitors in patients with exudative AMD.
In this paper, we propose an intravitreal implantable magnetic micropump integrated with micro check valve capable of on-demand vascular endothelial growth factor receptor (VEGFR)-targeted drug delivery for the treatment of age-related macular degeneration, diabetic retinopathy and other eye pathologies characterized by ocular neoangiogenesis.
