Inheritance of acetohexamide reductase activities in liver microsomes and cytosol of rats.
The inheritance patterns of acetohexamide reductase activities in liver microsomes and cytosol of rats were determined by using the inbred Wistar-Imamichi and Fischer-344 strains as a model of low and high metabolizers, respectively. A simple Mendelian genetic analysis for the frequency distribution of acetohexamide reductase activity in liver microsomes of male rats led us to conclude that the phenotype is genetically regulated by an autosomal co-dominant fashion. Female rats, unlike male rats, did not exhibit microsomal enzyme activity in parental, first filial (F1) and second filial (F2) generations, indicating that the inheritance of the microsomal enzyme activity is sex-limited. On the other hand, the frequency distribution of acetohexamide reductase activities in liver cytosol of male and female rats was unimodal in all generations and there was no significant difference among these cytosolic enzyme activities.
