Thrombopoietin: the novel hepatic hormone.
نویسندگان
چکیده
The glycoprotein thrombopoietin (TPO) is the major stimulator of megakaryopoiesis and platelet production. Hepatocytes express TPO mRNA at a constant rate. The plasma TPO level is inversely correlated to the mass of megakaryocytes and platelets, which degrade the hormone following its binding to specific membrane receptors.

Thrombopoietin.
By Shirley Ebbe I T HAS BEEN CLEAR for almost 20 years that platelet production is subject to homeostatic regulatory mechanisms that result in stimulation when the platelet count is li w’ and suppression when it is high.2 In spite of elapsed time, the physiologic processes that are involved in those regulatory mechanisms are not clear. Thrombocytopoiesis may be regulated by a humoral thrombopoi...
متن کاملThrombopoietin and its receptor, c-mpl, are constitutively expressed by mouse liver endothelial cells: evidence of thrombopoietin as a growth factor for liver endothelial cells.
Present data suggest that the primary site of thrombopoietin (TPO) mRNA is the liver. Previously, we reported that specific murine liver endothelial cells (LEC-1) located in the hepatic sinusoids support in vitro megakaryocytopoiesis from murine hematopoietic stem cells suggesting that these cells may be a source of TPO. We report here that TPO and its receptor, c-mpl, are coexpressed on cloned...
متن کاملPharmacokinetics and hepatic uptake of eltrombopag, a novel platelet-increasing agent.
Eltrombopag (ELT) is a novel thrombopoietin receptor agonist for the treatment of idiopathic thrombocytopenic purpura. Previous reports indicate that ELT is mainly eliminated in the liver, although its pharmacokinetic profile has not yet been clarified in detail. The purpose of the present study is to investigate the overall elimination mechanism of ELT. After intravenous administration of ELT ...
متن کاملOptimized Cytoplasmic Expression of Water Soluble Human Thrombopoietin in Modified Bacterial Strain
Background: Thrombopoietin is a glycoprotein produced by liver and kidney which is responsible for regulating the platelet production. Thrombopoietin is a key ligand with impact on regulating the self-renewal of Hematopoietic stem cells and the regulation of Megakaryocytes progenitors. Previous studies have indicated that only N-terminal domain of this protein has receptor promoting ability. Th...
متن کاملThrombopoietin and its receptor in normal and neoplastic hematopoiesis
Thrombopoietin was posited to exist in 1958 and cloned in 1994, and in the ensuing two decades we have learned a great deal about the physiology and pathology of the primary regulator of thrombopoiesis. This paper will review the role of the hormone and its receptor, the product of the c-Mpl proto-oncogene, in health and disease, including many unexpected effects in both normal and neoplastic h...
