The progress of prophylactic treatment in retinopathy of prematurity [PDF]

International Journal of Ophthalmology, 2018
Retinopathy of prematurity (ROP) is a retinal vascular disorder frequently found in premature infants. Different therapeutic strategies have been developed to treat ROP.

An Endostatin-lentivirus (ES-LV)-EPC gene therapy agent for suppression of neovascularization in oxygen-induced retinopathy rat model

BMC Molecular and Cell Biology, 2020
Background Transplantation of gene transfected endothelial progenitor cells (EPCs) has provided novel methods for tumor neovascularization therapy but not for ocular disease therapy.

YY1 lactylation in microglia promotes angiogenesis through transcription activation-mediated upregulation of FGF2

Genome Biology, 2023
Background Ocular neovascularization is a leading cause of blindness. Retinal microglia have been implicated in hypoxia-induced angiogenesis and vasculopathy, but the underlying mechanisms are not entirely clear.

Downregulation of PIK3IP1 in retinal microglia promotes retinal pathological neovascularization via PI3K-AKT pathway activation

Scientific Reports, 2023
Retinal pathological neovascularization involves endothelial cells, pericytes, photoreceptor cells, ganglion cells, and glial cells, whose roles remain unclear.

Deletion of LRP5 in VLDLR knockout mice inhibits retinal neovascularization. [PDF]

PLoS ONE, 2013
The development and maintenance of retinal vasculature require a precise balance between pro-angiogenic and anti-angiogenic factors. However, mechanisms underlying normal homeostasis of retinal vasculature and pathological changes of disrupted retinal ...

An allosteric peptide inhibitor of HIF-1α regulates hypoxia-induced retinal neovascularization

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Retinal ischemia causes hypoxia-induced neovascularization that stimulates production of proangiogenic cytokines such as VEGF by the hypoxia-inducible transcription factors HIF-1 and HIF-2.

Mass spectrometry in ocular drug research

Mass Spectrometry Reviews, EarlyView., 2023
Abstract Mass spectrometry (MS) has been proven as an excellent tool in ocular drug research allowing analyzes from small samples and low concentrations. This review begins with a short introduction to eye physiology and ocular pharmacokinetics and the relevance of advancing ophthalmic treatments.

Inhibiting NF-κB Signaling Activation Reduces Retinal Neovascularization by Promoting a Polarization Shift in Macrophages

Investigative Ophthalmology and Visual Science, 2020
Purpose Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling is involved in regulating tumor angiogenesis and metastasis; however, the exact mechanism of action in retinal neovascularization (RNV) remains unclear.

VEGF(164)-mediated inflammation is required for pathological, but not physiological, ischemia-induced retinal neovascularization [PDF]

, 2003
Hypoxia-induced VEGF governs both physiological retinal vascular development and pathological retinal neovascularization. In the current paper, the mechanisms of physiological and pathological neovascularization are compared and contrasted.

PPARα-Dependent Effects of Palmitoylethanolamide Against Retinal Neovascularization and Fibrosis

Investigative Ophthalmology and Visual Science, 2020
Purpose Pathological neovascularization and fibrosis are common pathological changes of many retinal diseases, such as proliferative retinopathy (PR) and age-related macular degeneration (AMD).
