Iron Status in Newborns Born to Iron-Deficient Mothers
Background: Iron deficiency anemia is one of the important problems during pregnancy. Iron deficiency has several adverse effects on pregnant women and their newborns. Objective: To determine the status of iron store in newborns born to mothers with iron deficiency anemia. Methods: In a cross-sectional study, 90 mothers were categorized into three groups according to their pre-delivery hemoglo...
متن کاملNdfip1-deficient mice have impaired DMT1 regulation and iron homeostasis.
The divalent metal ion transporter DMT1 is critical for nonheme iron import. We have previously shown that DMT1 is regulated in vitro by ubiquitination that is facilitated by the adaptor proteins Ndfip1 and Ndfip2. Here we report that in Ndfip1(-/-) mice fed a low- iron diet, DMT1 expression and activity in duodenal enterocytes are significant higher than in the wild-type animals. This correlat...
متن کاملIneffective hematopoiesis in folate-deficient mice.
A folate-free amino acid-based diet provided an opportunity to characterize the effects of folate depletion on growth, tissue folate levels, and hematopoiesis of mice under well-standardized conditions. Weanling mice were fed a folate-free, amino acid-based diet supplemented with either 0 or 2 mg folic acid/kg diet for 35 to 48 days. Folate concentrations were decreased in liver, kidney, serum,...
متن کاملDisturbed progastrin processing in carboxypeptidase E-deficient fat mice.
The fat mouse strain exhibits a late-onset obesity syndrome associated with a mutation in the gene encoding carboxypeptidase E (CPE). Since CPE plays a central role in the biosynthesis of a number of regulatory peptides, including gastrin, we examined the biogenesis and processing of progastrin in fat/fat mice by measuring gastrin mRNA, carboxyamidated gastrin and its processing intermediates i...
متن کاملDisturbed Processing of Contextual Information in HCN3 Channel Deficient Mice
Hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) in the nervous system are implicated in a variety of neuronal functions including learning and memory, regulation of vigilance states and pain. Dysfunctions or genetic loss of these channels have been shown to cause human diseases such as epilepsy, depression, schizophrenia, and Parkinson's disease. The physiological functions ...
