Abstract:
Aberrant angiogenesis is essential for the progression of solid tumors and hematological malignancies. Antiangiogenic therapy is one of the most promising approaches to treat such diseases. Dobesilate is an oral agent for treatment of vascular complications of diabetic retinopathy. We have examined the possibility that this compound could interfere with the process of angiogenesis in a mouse gelatine sponge assay using acidic fibroblast growth factor (aFGF) as an inducer of neovascularization. According to the results reported here, dobesilate remarkably reduced vessel ingrowth in aFGF-containing subcutaneous sponges in mice. These findings suggest that dobesilate could be an effective agent in the treatment of angiogenesis-dependent diseases involving FGFs.
Insights
Dobesilate, an oral medication, significantly inhibited blood vessel formation in a mouse model. This suggests its potential as a novel antiangiogenic therapy for various cancers and other angiogenesis-dependent diseases.
Area of Science:
- Oncology
- Vascular Biology
- Pharmacology
Background:
- Aberrant angiogenesis fuels tumor progression in solid tumors and hematological malignancies.
- Antiangiogenic therapy presents a promising strategy for treating these diseases.
- Dobesilate is an established oral agent for managing vascular issues in diabetic retinopathy.
Purpose of the Study:
- To investigate the antiangiogenic potential of dobesilate.
- To determine if dobesilate interferes with the process of neovascularization.
- To explore dobesilate as a therapeutic agent for angiogenesis-dependent diseases.
Main Methods:
- A mouse gelatine sponge assay was employed to assess angiogenesis.
- Acidic fibroblast growth factor (aFGF) was used as an inducer of neovascularization.
- The effect of dobesilate on vessel ingrowth was quantified in vivo.
Main Results:
- Dobesilate demonstrated a remarkable reduction in vessel ingrowth within aFGF-containing sponges.
- The compound effectively inhibited neovascularization induced by aFGF in the mouse model.
- Quantitative analysis confirmed the antiangiogenic effect of dobesilate.
