Fig. 4. — The effect in the isolated rat heart of the PKC activator phorbol myristate acetate (phorbol; 1 μM), the adenosine A₁R agonists R-(−)N⁶-(2-phenylisopropyl)-adenosine (PIA; 1 μM) and CCPA (1 μM), and 8-cyclopentyl-1,3-dipropylxanthine (DPCPX; 0.1 μM) on the coimmunoprecipitation of PKC-ɛ with RACK2. Agents were administered to isolated hearts at the concentration indicated for 5 min in the continuous presence of the A_2AR antagonist ZM-241385 (1 μM). RACK2 was immunoprecipitated using the RACK2 antibody anti-TCP-1α. Values are mean ± SE of 2–5 hearts. *Significant difference from control (P ≤ 0.05). †Significant difference from CCPA (P ≤ 0.05).
