Cardiovascular disease is the leading cause of the poor long-term survival of patients with chronic kidney disease (CKD). Anemia complicating CKD not only impairs patients' quality of life, but is also an independent risk factor for adverse cardiovascular outcomes. The availability of recombinant human erythropoietin (rHuEPO) has greatly changed the management of anemia in CKD patients. Besides...

We previously reported that erythropoietin (Epo) has a mitogenic effect on rat vascular smooth muscle cells (VSMC) and that activation of the mitogen-activated protein kinase (MAPK) cascade is an important mediator for Epo-induced mitogenesis. An increase in intracellular cAMP has an antiproliferative effect on VSMC. We therefore hypothesized that cAMP effectors inhibit Epo-induced MAPK activat...

In an attempt to reduce or eliminate homologous red blood cell transfusion requirements during allogeneic bone marrow transplantation (BMT), we instituted a novel program whereby recombinant human erythropoietin was administered to pairs of BMT donors and recipients. Eleven recipients and their HLA-matched donors were enrolled. Donors treated with recombinant human erythropoietin (rHuEPO) were ...

Erythropoietin (EPO), a glycoprotein hormone of ∼ 34 kDa, is an important hematopoietic growth factor, mainly produced in the kidney and controls the number of red blood cells circulating in the blood stream. Sensitive and rapid recombinant human EPO (rHuEPO) detection tools that improve on the current laborious EPO detection techniques are in high demand for both clinical and sports industry. ...

Erythropoietin (Epo) is a true hematopoietic hormone produced in response to lowered oxygen tension. The liver is the main source of Epo during most of fetallife, but the liver to kidney switch occurs around birth so that 90% of Epo synthesis takes place in the kidney very soon in life. E!evated serum Epo levels are observed at birth in the case of maternaI hypertension, akoholism, or diabetes ...

The pharmacokinetic profile of recombinant human erythropoietin (rHuEpo) was studied after a single intravenous dose of 150 U/kg in ten patients with various degrees of renal function: group I, creatinine clearance greater than 80 ml/min, n = 2; group II, creatinine clearance 10-50 ml/min, n = 6; group III, creatinine clearance less than 3 ml/min (patients undergoing haemodialysis) n = 2. Eryth...

Recombinant human erythropoietin (rHUEPO) was produced by Chinese hamster ovary cells and commercially distributed to hospitals by two pharmaceutical companies in Japan ('ESPO' by Kirin Brewery Co. Ltd., and Sankyo Co. Ltd., and 'EPOGIN' by Chugai Pharmaceutical Co. Ltd.) These products contained about 1% N-glycolylneuraminic acid (Neu5Gc) in total sialic acid content. Since humans do not synth...

We have established four hybridoma cells that produce monoclonal antibodies (MoAbs) R2, R4, R6, and R12 directed toward recombinant human erythropoietin (rHuEPO). MoAbs R2, R4, and R6 bound to EPO with high affinities (kd = approximately 2, 4, and 1 nmol/L, respectively) but MoAb R12 had a low affinity (240 nmol/L). These antibodies inhibited the biological activity of rHuEPO and EPOs from huma...

The detection in urine of recombinant human erythropoietin (rHuEPO), a hormone misused by endurance athletes as a doping agent, is based on the differentiation of its isoelectric pattern from that of the corresponding natural hormone. Different empirical criteria have been proposed for discriminating the images of the patterns but none of them have been elaborated from a rational statistical ap...
