Intracellular metabolism of adenosine to AMP is essential for phosphorylation of AMPK. Representative Western blots of HUVEC pre-treated for 30 minutes with either an inhibitor of adenosine kinase, AMDA (10 μmol/L) or inhibitor of adenosine deaminase, EHNA (10 μmol/L), and stimulated with adenosine (ADO) (25 μmol/L, 5 minutes). Cell lysates were immunoblotted with anti-P-AMPK (Thr-172), anti-AMPK-α and anti-P-ACC antibodies. Values are means ± S.E.M of 3-4 independent experiments. *P<0.05, compared to control.
