Abstract
AbstractThe consumption of high-fructose corn syrup (HFCS) has been increasing in recent
decades, especially among children. Some reports suggest that children and
adolescents are more sensitive to the adverse effects of fructose intake than
adults. However, the underlying mechanism of the difference in vulnerability
between adolescence and adulthood have not yet been elucidated. In this study,
we attempted to elucidate the different effects of HFCS intake at different
growth stages in rats: childhood and adolescence (postnatal day (PD)
21–60), young adulthood (PD60–100), and adulthood
(PD100–140). Since alterations in hepatic glucocorticoid (GC) metabolism
can cause diseases including insulin resistance, we focused on GC metabolizing
enzymes such as 11 beta-hydroxysteroid dehydrogenase 1 and 2 (Hsd11b1 and
Hsd11b2) and steroid 5 alpha-reductase 1 (Srd5a1). Western blotting showed an
increase in Hsd11b1 expression and a decrease in Hsd11b2 expression in childhood
and adolescence but not in adulthood. We also observed changes in Hsd11b1 and
Hsd11b2 activities only in childhood and adolescence, consistent with the
results of mRNA and protein expression analysis. The effect of high-fructose
intake with regards to GC metabolism may therefore vary with developmental
stage. This study provides insight into the adverse effects of fructose on GC
metabolism in children in the context of increasing rates of HFCS
consumption.

Abstract
11beta-Hydroxysteroid dehydrogenase type 1 (11HSD1) is an enzyme that interconverts active 11-hydroxy glucocorticoids (cortisol, corticosterone) and their inactive 11-oxo derivatives (cortisone, 11-dehydrocorticosterone). Although bidirectional, it is considered to operate in vivo as an 11-reductase that regenerates active glucocorticoids and thus amplifies their local activity in mammals. Here we report the cloning, characterization and tissue distribution of chicken 11HSD1 (ch11HSD1). Its cDNA predicts a protein of 300 amino acids that share 51-56% sequence identity with known mammalian 11HSD1 proteins, while in contrast to most mammals, ch11HSD1 contains only one N-linked glycosylation site. Analysis of the tissue distribution pattern by RT-PCR revealed that ch11HSD1 is expressed in a large variety of tissues, with high expression in the liver, kidney and intestine, and weak in the gonads, brain and heart. 11-Reductase activity has been found in the liver, kidney, intestine and gonads with low or almost zero activity in the brain and heart. These results provide evidence for a role of 11HSD1 as a tissue-specific regulator of glucocorticoid action in non-mammalian vertebrates and may serve as a suitable model for further analysis of 11HSD1 evolution in vertebrates.
