Deferasirox Reduces Iron Overload in a Murine Model of Juvenile Hemochromatosis.

Abstract: Introduction: Targeted disruption of the hemojuvelin gene in mice (HJV−/−) has recently been reported to cause markedly increased liver, pancreas and heart iron deposition, and act as a model for juvenile hemochromatosis (Niederkofler et al. 2005, Huang et al. 2005). Deferasirox, a novel tridentate oral iron chelator, is effective in the treatment of patients with transfusional iron overload and it has not been investigated in primary iron overload. We sought to examine spontaneous iron loading and the effect … Show more

“…In pharmacokinetics studies, its properties in mice were comparable with the human situation (22). In addition, and comparable to the human situation, deferasirox was found to be effective in reducing murine iron levels in plasma and in several tissues (17,23). Also, in our study, treatment with deferasirox resulted in a decrease in the plasma levels of ferritin, an iron storage protein which reflects the amount of stored iron, and reduced positive synovial iron staining, indicating that the deferasirox treatment was effective in chelation of iron in the joint tissue.…”

“…This dose was found to be effective and safe for mice in previous studies. [17] Deferasirox was suspended in 0.5 % aqueous Klucel HF (hydroxypropylcellulose), the standard vehicle for deferasirox. Each animal received 0.1ml deferasirox-Klucel suspension (deferasirox group).…”

“…The current study also tested deferasirox as an antifibrotic agent in the Mdr2 –/– mouse model of hepatic fibrosis. The dose of deferasirox used (30 mg/kg/day) has been shown to have limited effects on tissue iron concentration and enabled us to assess the antifibrotic activity of deferasirox independent of iron chelation . There were no changes in hepatic or splenic iron concentrations following deferasirox therapy and small increases in both serum iron and transferrin saturation, confirming that there was limited iron chelation at this dose.…”

“…Mdr2 –/– mice (four male and four female per group) were treated with vehicle (0.5% hydroxypropylcellulose) or deferasirox (30 mg/kg/day) by daily oral gavage from 3 to 7 weeks of age. This dose of deferasirox has previously been shown to have limited effects on tissue iron levels in a mouse model and allowed us to assess antifibrotic activity independent of iron chelation. The study was approved by the University of Queensland Animal Ethics Committee and performed according to the Australian code for the care and use of animals for scientific purposes.…”

“…Экспериментальные модели наследственной РКМП воспроизводят клинические ситуации наследственного гемохроматоза и мутаций саркомерных белков. Биомоделью наследственного гемохроматоза являются мыши с гомозиготным нокаутированием гена гемоювелина (JUV-/-) [20,34]. У животных было отмечено интенсивное накопление железа в печени, поджелудочной железе и сердце.…”
