Fig. 1.

Upper panel: 2% Agarose gel electrophoresis RT-PCR results for adenosine receptors. 18 s ribosomal RNA 71BP, adenosine A₁ receptor 97BP, adenosine A_2A receptor 122BP, adenosine A_2B receptor 255BP, adenosine A₃ receptor 171BP and β(B)-actin 122BP. Lower panel: Graph demonstrating the relative expression of adenosine A₁, A_2A and A_2B receptor subtypes on E.Ahy926 endothelial cells. The data was analysed using one-way ANOVA. Data is expressed as mean ± SEM (n = 6), *P < 0.05 versus adenosine A₁ receptor
