Cytochrome P4501A2 (Cyp1a2) is important in the development of uroporphyria in mice, a model of porphyria cutanea tarda in humans. Heretofore, mice homozygous for the Cyp1a2−/− mutation do not develop uroporphyria with treatment regimens that res

Objective Levels of tissue iron contribute to determining diabetes risk, but little is known about the effects of higher iron levels on weight, and on the interaction of weight and iron overload on diabetes risk. Therefore, the effect of iron on body

The response of hepatic mono-oxygenase activities to Aroclor 1254 or 3-methylcholanthrene was investigated in wild-type and Cyp1a2(-/-) mice. Cytochrome P450 concentrations were similar in naive Cyp1a2(-/-) and wild-type mice. There was no difference

Hepatic siderosis is common in patients with porphyria cutanea tarda (PCT). Mutations in the hereditary hemochromatosis (hh) gene (HFE) explain the siderosis in approximately 20% patients, suggesting that the remaining occurrences result from additio

Hereditary hemochromatosis is an inherited disorder of increased iron absorption that can result in cirrhosis, diabetes, and other morbidities. We have investigated the mechanisms underlying supranormal glucose tolerance despite decreased insulin sec

We investigated protracted low-dose oral Clofarabine for the treatment of myelodysplastic syndromes (MDS). Adults with an International Prognostic Scoring System (IPSS) score of INT-1 or higher who had failed first line therapy were eligible. INT-1 p

In mammalian cells the rate-limiting step in heme biosynthesis is the formation of δ-aminolevulinic acid (ALA). The reaction intermediates, porphyrins and iron and the final product, heme can be highly cytotoxic if allowed to accumulate. The importa

We recently demonstrated that humans with hereditary haemochromatosis have decreased insulin secretory capacity with a compensatory increase in insulin sensitivity. We therefore determined how these measures change after correction of tissue iron ove

Most iron in mammalian systems is routed to mitochondria to serve as a substrate for ferrochelatase. Ferrochelatase inserts iron into protoporphyrin IX to form heme which is incorporated into hemoglobin and cytochromes, the dominant hemoproteins in m

The prevalence and mechanisms of diabetes in hereditary haemochromatosis are not known. We therefore measured glucose tolerance, insulin secretory capacity and insulin sensitivity in adults with haemochromatosis.Subjects recruited from referrals to a
