| 1 | Combined treatment of 3-hydroxypyridine-4-one derivatives and green tea extract to induce hepcidin expression in iron-overloaded b-thalassemic mice显示文摘Objective:To evaluate the efficacy of deferiprone(DFP),1-(N-acetyl-6-aminohexyl)-3-hydroxy-2-methylpyridin-4-one(CM1)or green tea extract(GTE)in enhancing expression of hepatic hepcidin1(Hamp1)m RNA and relieving iron overload in b-globin knockout thalassemic mice.Methods:The b-globin knockout thalassemic mice were fed with a ferrocenesupplemented diet for 2 months and oral administration of deionized water,DFP(50 mg/kg),CM1(50 mg/kg),GTE(50 mg epigallocatechin 3-gallate equivalent/kg),GTE along with DFP(50 mg/kg),and GTE along with CM1(50 mg/kg)every day for 3months.Levels of hepatic Hamp1 m RNA,plasma non-transferrin bound iron,plasma alanine aminotransferase activity and tissue iron content were determined.Results:All chelation treatments could reduce plasma non-transferrin bound iron concentrations.Additionally,hepatic Hamp1 m RNA expression was significantly upregulated in the mice in a GTE+DFP combined treatment,correlating with a decrease in the plasma alanine aminotransferase activity and tissue iron deposition.Conclusions:The GTE+DFP treatment could ameliorate iron overload and liver oxidative damage in non-transfusion dependent b-thalassemic mice,by chelating toxic iron in plasma and tissues,and increasing hepcidin expression to inhibit duodenal iron absorption and iron release from hepatocytes and macrophages in the spleen.There is probably an advantage in giving GTE with DFP when treating patients with iron overload. | Supranee Upanan Kanjana Pangjit Chairat Uthaipibull Suthat Fucharoen Andrew T.Mc Kie Somdet Srichairatanakool | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，12： | 0 |
