Aceruloplasminemia is an autosomal recessive disorder caused by mutations in the ceruloplasmin (CP) gene. It is characterized by iron accumulation in the brain and in visceral organs. However, little is known about the mechanism of iron transport in these regions. Adult CP null (CP(-/-)) mice show increased iron deposition in several regions of brain, such(More)
This study aims at developing new organoselenium compounds with good anticancer ability and low biotoxicity. Sucrose selenious ester (sucrose-Se) was synthesized by the reaction between sucrose and selenium oxychloride. MTT assay showed that sucrose-Se effectively inhibited the proliferation of cervical cancer cell line HeLa in a dose-dependent manner(More)
A convenient and rapid method for the genetic transformation of Escherichia coli with plasmids is proposed. By mixing the recipient cells and plasmid DNA and spreading them directly on selective medium plates containing Ca2+, the so-called 'plate transformation' could achieve almost the same transformation efficiency as the classical transformation method(More)
Hepcidin, a principle regulator of iron metabolism, is synthesized by the liver. Contradictory results have been reported on the regulation of hepcidin expression in response to serum transferrin saturation and liver iron content. In the present study, we explore the expression of murine hepcidin mRNA and further analyze the relationship between liver(More)
Two organoselenium compounds: xylitol selenious ester (xylitol-Se) and sucrose selenious ester (sucrose-Se) were synthesized, and their molecular structures were characterized in this study. In MTT assay, xylitol-Se and sucrose-Se showed cytostatic effects on human hepatocellular carcinoma cells SMMC-7221 in a dose-dependent manner, whereas they had no(More)
