Abstract

Background Choroidal neovascularization (CNV) is the main cause of severe visual loss in age-related macular degeneration (AMD). Heparin/heparan sulfate are known to play important roles in neovascularization due to their abilities to bind and modulate angiogenic growth factors and cytokines. Previously, we have isolated from marine shrimp a heparin-like compound with striking anti-inflammatory action and negligible anticoagulant and hemorrhagic activities.Objectives To investigate the role of this novel heparin-like compound in angiogenic processes.Methods and results The anti-angiogenic effect of this heparinoid in laser-induced CNV and in vitro models is reported. The compound binds to growth factors (FGF-2, EGF and VEGF), blocks endothelial cell proliferation and shows no cytotoxic effect. The decrease in proliferation is not related to cell death either by apoptosis or secondary necrosis. The results also showed that the heparinoid modified the 2-D network organization in capillary-like structures of endothelial cells in Matrigel and reduced the CNV area. The effect on CNV area correlates with decreases in the levels of VEGF and TGF-β1 in the choroidal tissue. The low content of 2-O-sulfate groups in this heparinoid may explain its potent anti-angiogenic effect.Conclusions The properties of the shrimp heparinoid, such as potent anti-angiogenic and anti-inflammatory activities but insignificant anticoagulant or hemorrhagic actions, point to this compound as a compelling drug candidate for treating neovascular AMD and other angioproliferative diseases. A mechanism for the anti-angiogenic effect of the heparinoid is proposed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
