Dysfunctional oxidative phosphorylation (OXPHOS) increases vascular endothelial growth factor (VEGF) and pathological angiogenesis. Enhancing OXPHOS function may offer a therapeutic strategy for angiogenesis-related diseases.
Area of Science:
- Biochemistry
- Molecular Biology
- Pathology
Background:
- Oxidative phosphorylation (OXPHOS) is crucial for cellular energy production.
- Dysfunction in OXPHOS is linked to increased vascular endothelial growth factor (VEGF) and pathological angiogenesis.
- Angiogenesis-related diseases like retinal diseases, rheumatoid diseases, and cancer often exhibit OXPHOS dysfunction.
Purpose of the Study:
- To investigate the role of OXPHOS in pathological angiogenesis.
- To explore the potential of enhancing OXPHOS as a therapeutic strategy for angiogenesis-related diseases.
Main Methods:
- Analysis of OXPHOS pathway function.
- Assessment of VEGF production.
- Evaluation of angiogenesis in disease models.
Main Results:
- Pathological mutations or inhibition of OXPHOS subunits lead to increased VEGF production.
- OXPHOS dysfunction is a common feature in various angiogenesis-related diseases.
- Targeting OXPHOS presents a potential therapeutic avenue.
Conclusions:
- OXPHOS dysfunction is a key driver of pathological angiogenesis.
- Therapeutic enhancement of OXPHOS holds promise for treating angiogenesis-related diseases.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
