I dont have time to follow this up at the moment but have a vague recollection of an interesting trial looking at gene expression and VEGF.
But here is one I have just googled that may indicate a link between COX 2 and VEGF, albeit in a different area of body function. I have not had a chance to more than skim the opening but it has some interesting bits and underlines the complexity of it all.
