Association of mouse liver adenosine 3':5'-cyclic monophosphate (cyclic AMP) levels with histocompatibility-2 genotype.

RESUMO

When the content of cyclic AMP (cAMP) was compared in livers of a series of congenic mouse strains differing at the H-2 locus, significant variation in concentration of cAMP per unit wet weight was found among strains, and also for animals of a given strain with increasing age. For a given age, from 8 to 22 weeks, cAMP levels in liver of H-2a and H-2b genotype animals were significantly higher than that in liver of H-2k type animals. This difference was seen whether the H-2 gene was on the genetic background of strain C57BL/10, C3H, or A. Levels of cAMP in livers of H-2d animals were between those of H-2a and H-2k animals.
