Hemojuvelin (Hjv) is a bone morphogenetic protein (BMP) co-receptor involved in the control of systemic iron homeostasis. Functional inactivation of Hjv leads to severe iron overload in humans and mice due to marked suppression of the iron-regulatory hormone hepcidin. To investigate the role of Hjv in body iron sensing, Hjv-/- mice and isogenic wild type controls were placed on a moderately low...

The recently discovered repulsive guidance molecule c (RGMc or hemojuvelin) gene encodes a putative glycosylphosphatidylinositol (GPI)-anchored protein that is expressed in striated muscle and in liver. Mutations in this gene have been linked to the severe iron storage disease, juvenile hemochromatosis, although the mechanisms of action of RGMc in iron metabolism are unknown. As a first step to...

Hemojuvelin (HJV) was recently identified as a critical regulator of iron homeostasis. It is either associated with cell membranes through a glycosylphosphatidylinositol anchor or released as a soluble form. Membrane-anchored HJV acts as a coreceptor for bone morphogenetic proteins and activates the transcription of hepcidin, a hormone that regulates iron efflux from cells. Soluble HJV antagoni...

results using these two sets, we identified h1069q mutation in four patients, c.2335t > g mutation in three, c.3061-1g > a splice site mutation in five, c.3305t > c mutation in one, and c.3809a > g mutation in two patients. conclusions the multiplex arms assay used in this study can be an efficient, reliable, and cost effective method as a primary screen for patients with wilson disease. patien...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an enzymopathy affecting about 400 millionpeople worldwide. The distribution of G6PD deficiency and the molecular genetics of this enzyme vary widelyamong different ethnic groups. The aim of this study was to find out the frequency of G6PD deficiency andcharacterize the Mediterranean type mutation in deficient individuals ...

background: glucose-6-phosphate dehydrogenase (g6pd) is an x-linked enzymopathy affecting about 400 million people worldwide. neonatal jaundice, drug induced haemolysis and infection-induced haemolysis may happen in some deficient individuals and lead to considerable mortality. the distribution of g6pd deficiency and the molecular genetics of this enzyme vary widely among different ethnic group...

xanthan gum is a microbial polysaccharide of great commercial importance as it has unusual rheological properties in solution and consequent range of applications. in this study, a series of mutants were isolated from xanthomonas campestris ptcc 1473 by ethyl methanesulfonate mutagenesis. the polysaccharide yield of one mutant, xc1473e2, was 30% better than that of the parent strain. it also sh...

background: trichomoniasis is a worldwide protozoan parasitic disease and metronidazole is a choice drug for its treatment. because of disease importance in public health and its controversial ideas about the prevalence of drug resistance, this study was carried out. methods: fifty-two suspected vaginal samples were collected from 2006 to 2007 in gynecology maryam hospital, tehran, iran. all is...
