title: Regulation of protein disulfide isomerase gene expression in brain and liver during rat development.
abstract: A 4-fold increase in protein disulfide isomerase (PDI) mRNA is observed in brain of 10 days-old rats and in liver of 20 days-old foetuses when compared with 20 days-old (brain) and 18 days-old (liver) foetuses respectively. During further postnatal development, the mRNA for PDI decreases in both organs to the initial values present in foetuses and remains practically unchanged in brain till the adult. By contrast in liver by 35-40 days after birth, and coincident with sexual maturation, there is a 2.5-fold increase in PDI mRNA that is maintained by 55 days (adult). These results clearly show that protein disulfide isomerase gene expression is differentially regulated in liver and brain during rat development.
