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.
当对一系列在H-2位点存在差异的同源近交系小鼠肝脏中的环磷酸腺苷(cAMP)含量进行比较时,发现不同品系之间每单位湿重的cAMP浓度存在显著差异,而且对于给定品系的动物,随着年龄增长也存在差异。对于8至22周龄的给定年龄组,H-2a和H-2b基因型动物肝脏中的cAMP水平显著高于H-2k型动物肝脏中的水平。无论H-2基因位于C57BL/10、C3H或A品系的遗传背景上,这种差异都能观察到。H-2d动物肝脏中的cAMP水平介于H-2a和H-2k动物之间。
