Essais Erythropoietin (EPO)

Hormone involved in the regulation of erythrocyte proliferation and differentiation and the maintenance of a physiological level of circulating erythrocyte mass. Binds to EPOR leading to EPOR dimerization and JAK2 activation thereby activating specific downstream effectors, including STAT1 and STAT3.

This gene encodes a secreted, glycosylated cytokine composed of four alpha helical bundles. The encoded protein is mainly synthesized in the kidney, secreted into the blood plasma, and binds to the erythropoietin receptor to promote red blood cell production, or erythropoiesis, in the bone marrow. Expression of this gene is upregulated under hypoxic conditions, in turn leading to increased erythropoiesis and enhanced oxygen-carrying capacity of the blood. Expression of this gene has also been observed in brain and in the eye, and elevated expression levels have been observed in diabetic retinopathy and ocular hypertension. Recombinant forms of the encoded protein exhibit neuroprotective activity against a variety of potential brain injuries, as well as antiapoptotic functions in several tissue types, and have been used in the treatment of anemia and to enhance the efficacy of cancer therapies.

Produced by kidney or liver of adult mammals and by liver of fetal or neonatal mammals.

Microvascular complications of diabetes 2: Pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.

Erythrocytosis, familial, 5: An autosomal dominant disorder characterized by elevated serum hemoglobin and hematocrit. Some patients have increased serum erythropoietin levels.

Diamond-Blackfan anemia-like: An autosomal recessive hematologic disease characterized by severe red cell hypoplastic anemia, selective absence of red cell precursors and progenitors seen on bone marrow biopsy, and increased serum erythropoietin.

Belongs to the EPO/TPO family.

Secreted.
