Does adenosine mediate hypoxic induction of vascular endothelial growth factor in retinal pericytes and endothelial cells?
These data suggest that the hypoxia-induced accumulation of adenosine stimulates VEGF gene expression through stimulation of adenosine A2a receptor and subsequent activation of the cAMP-dependent protein kinase A pathway in retinal vascular cells.
