Correlation between iron status and genetic hemochromatosis (codon C282Y) in a large German population.

Background: Genetic hemochromatosis leads to iron overload in many tissues and may lead to liver cirrhosis and hepatocellular carcinoma. Early diagnosis and therapy are crucial. Since 80-100% of hemochromatosis patients of European origin are homozygous for a cysteine to tyrosine exchange in the HFE gene at codon 282, genetic screening might be useful.

Synergistic effects of troglitazone and oleate on the translatability of preproinsulin mRNA from INS-1 cells.

Glitazones are known to modulate fatty acid-induced effects on insulin secretion in the pancreatic beta-cell. The present study focused on combined effects of troglitazone and oleate on preproinsulin (PPI) biosynthesis. Insulin-producing INS-1 cells were incubated for 4 hr at 11.
