Tmprss6-mutated mask mice display iron deficiency anemia and high expression of hepcidin. The aim of the study was to determine the effect of erythropoietin administration on proteins participating in the control of iron homeostasis in the liver and spleen in C57BL/6 and mask mice. Administration of erythropoietin for four days at 50 IU/mouse/day increased hemoglobin and hematocrit in C57BL/6 m...

BACKGROUND Although vascular endothelial growth factor (VEGF) is a primary mediator of retinal angiogenesis, VEGF inhibition alone is insufficient to prevent retinal neovascularization. Hence, it is postulated that there are other potent ischemia-induced angiogenic factors. Erythropoietin possesses angiogenic activity, but its potential role in ocular angiogenesis is not established. METHODS ...

There is limited evidence that the tissue-protective effects of erythropoietin are mediated by a heterocomplex of the erythropoietin receptor and the β-common receptor ('tissue-protective receptor'), which is pharmacologically distinct from the 'classical' erythropoietin receptor homodimer that is responsible for erythropoiesis. However, the role of the β-common receptor and/or erythropoietin i...

normal 0 false false false en-us x-none fa microsoftinternetexplorer4 background : erythropoietin (epo) as a major stimulator of red blood cell (rbc) production play a key role on brain protection and have a caring effect on neurons from hypoxic or traumatic injury. the objective of this trial was to study the safety and efficacy of recombinant human epo (rhepo) on level of consciousness and ot...

conclusions epo resistance was negatively associated with anti-hbs levels and seroconversion. more studies are needed to highlight the underlying mechanisms regarding epo resistance and response to hbv vaccination in hd patients. results in total 97 patients were enrolled. for the entire group, stepwise linear regression analysis revealed that square root transformed anti-hbs levels were indepe...

recent studies in animal models indicate that recombinant human erythropoietin (rhepo) is very effective in enhancing neurological recovery after spinal cord injury (sci). we aimed to evaluate the effect of rhepo plus methylprednisolone sodium succinate (mpss) compared to mpss alone to improve neurological function of patients after sci in a randomized clinical trial. during a 15-month period 3...

background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...

background and objective: the anemia of esrd is a complex disorder, associated with serious complications, which increases patients’ mortality and morbidity. treatment of this anemia with recombinant human erythropoietin (rh-epo) is well established. this clinical trial study was conducted within 20 months, from may 2005 to december 2006, in order to evaluate the efficacy of pdpoetin (rh-epo al...

The quantitative relationship between red cell volume, erythropoietin level, and erythropoiesis was evaluated in 43 human beings. Results in normal man were compared with studies in patients with anemia from bone marrow failure and with polycythemia vera. The maximum erythropoietin excretion after bleeding normal men was similar to the basal levels found in patients with chronic anemia of simil...

Erythropoietin gene expression is greatly stimulated under conditions of hypoxia. The activation of the erythropoietin gene appears regulated primarily at the level of gene transcription. To study cis-acting elements involved in the response to hypoxia a mini-gene was constructed by an internal deletion from exon II to V of the human erythropoietin gene and used in transient transfection assays...
