Patients undergoing antiviral therapy for chronic hepatitis C often develop anemia secondary to ribavirin and interferon. Recombinant erythropoietin has been used to improve anemia associated with antiviral therapy and to minimize dose reductions, which are associated with decreased rates of sustained virologic response. A rare potential side effect of recombinant erythropoietin is anti-erythro...
A Deterministic Finite Automaton is constructed to identify the human protein called Erythropoietin from a large collection of proteins. This new technique is a computational procedure to identify erythropoietin without using in vitro methods. This scheme accurately reflects a DNA computer serving as a tool to analyze specified protein that can be matched with an already programmed protein sequ...
It has been known for 40 years that erythropoietin, which is mainly produced by the kidney in response to hypoxia, is the primary regulator of red blood cell production and is indispensable for terminal differentiation of erythroid progenitors. It controls proliferation, maturation and also survival of erythroid progenitor cells. The binding of erythropoietin to its receptor, which exists as a ...
OBJECTIVE Erythropoietin has been recently found to be increased in the vitreous fluid from ischemic retinal diseases such as proliferative diabetic retinopathy (PDR). The aims of the present study were 1) to measure erythropoietin levels in the vitreous fluid from patients with diabetic macular edema (DME), a condition in which the ischemia is not a predominant event, and 2) to compare erythro...
Erythropoietin is the major regulator of the proliferation and differentiation of erythroid precursors, but little is known about its molecular mechanism of action. Using a human erythroleukemic cell line (HEL), we investigated whether p21ras is involved in erythropoietin signal transduction. We found that stimulation of HEL cells with erythropoietin induces a 5-fold increase in the amount of G...
Erythropoietin is a hypoxia-induced cytokine that stimulates erythropoiesis through the promotion of erythroid precursor cell proliferation and differentiation. Recent evidence supports that erythropoietin has a broad spectrum of tissue protecting actions affecting other systems than hemopoietic. Lately, research has focused on the nonhemopoietic effects of erythropoietin against tissue ischemi...
Anaemia effects up to 90% of cancer patients, with more than 60% requiring blood transfusion during or after treatment. With the advent of recombinant human erythropoietins (rHuEPO), an alternative to red blood cell transfusion has become available. So far, three drugs have been approved for the treatment of anaemia in patients with malignancies (epoetin alfa, epoetin beta and darbepoetin alfa)...
The identity of the peritubular population of cells with mesenchymal phenotype thought responsible for producing erythropoietin in humans remains unclear. Here, renal CD133(+)/CD73(+) progenitor cells, isolated from the human renal inner medulla and described as a population of mesenchymal progenitors, released erythropoietin under hypoxic conditions. CD133(-) cells did not synthesize erythropo...
INTRODUCTION Erythropoietin is administered for treatment of anemia in chronic kidney disease and kidney transplantation. Erythropoietin improves oxygenation of organs and prevents them against apoptosis. The aim of this study was evaluation of erythropoietin's effect on graft survival in the early phase after transplantation. MATERIALS AND METHODS Forty kidney transplant candidates with a he...
