Effect of chlorocyclopentyl adenosine (CCPA) and anti-Gβγ peptide on inositol 1,4,5-triphosphate (IP3) produced in homogenates of hearts obtained from wild-type and adenosine A1 receptor (A1R) knockout (KO) mice. CCPA and peptide were administered at 1 and 50 μM, respectively. The A1R antagonist 8-cyclopentyl-1,3-dipropylxanthine (DPCPX) was administered at 100 nM. Values are means ± SE for 3–4 hearts. *Mean is significantly different from the agent-free value (P < 0.05). †Means are significantly different from the CCPA-alone value (P < 0.05).
