Polymorphism of cyclic 3',5'-adenosine monophosphate stimulation in rat erythrocytes
1Department of Pathology, School of Medicine, University of Pittsburgh, Pa.
Abstract:
Significant differences were found in the cyclic 3',5'-adenosine monophosphate (cAMP) levels in (-)-isoproterenol-stimulated rat erythrocytes. The BN strain had the highest level (13.1 +/- 1.29 pmol cAMP/10 mg Hb) and the LEW strain had the lowest cAMP level (3.29 +/- 1.76 pmol cAMP/10 mg Hb) in the erythrocytes. The high levels were inherited in three intercrosses in a dominant fashion. The results of the backcross breeding suggested diallelic inheritance. However, the polygenic effect was not ruled out.
