Aplicação
Thrombopoietin from mouse can be used in a genetic screening test for examining the role of somatic activating mutations in EPOR, MPL, or GCSFR genes in activating myeloproliferative disorders (MPD) in JAK2V617F-negative MPD patients.[1]
Ações bioquímicas/fisiológicas
TPO is a ligand for the c-mpl proto-oncogene (Mpl-L), a megakaryocyte colony stimulating factor (Meg-CSF), and a primary regulatory factor for megakaryocytopoiesis and thrombopoiesis. TPO is a humoral glycoprotein that stimulates growth and maturation of megakaryocytes and megakaryocytic colonies from bone marrow cultures. TPO binds and activates a 68-78 kDa glycoprotein receptor belonging to the GH family of cytokine receptors, a family that includes receptors to growth hormone (GH), erythropoietin (EPO) and prolactin (PRL). TPO receptors are found on megakaryocytes and their precursors and on platelets. The mature form of TPO is a highly conserved, showing approximately 70% sequence homology among various mammals.
Thrombopoeitin (TPO), also known as the ligand for the c-mpl proto-oncogene (Mpl-L) and as megakaryocyte colony stimulating factor (Meg-CSF), is a primary regulatory factor for megakaryocytopoiesis and thrombopoiesis. Produced mainly by hepatocytes but also by kidney cells, TPO is a humoral glycoprotein that stimulates growth and maturation of megakaryocytes and megakaryocytic colonies from bone marrow cultures. TPO binds and activates an 68-78 kDa glycoprotein receptor belonging to the GH family of cytokine receptors, a family that includes receptors to growth hormone (GH), erythropoietin (EPO) and prolactin (PRL). Like GH and EPO, TPO may bind to its receptor at two distinct sites, initiating receptor dimerization and activation. Analysis of mRNA indicates also the existence of a novel truncated and potentially soluble form of TPO receptor. The viral oncogene v-mlp of the myeloproliferative leukemia virus (MPLV) contains the gene sequence for the entire cytoplasmic and transmembrane domains and a portion of the extracellular domain of c-mlp (TPO receptor). TPO receptors are found on megakaryocytes and their precursors and on platelets. The mature form of TPO is a highly conserved glycoprotein, showing approximately 70% sequence homology among various mammals. Human TPO contains 332 amino acids (mouse 335) including two internal disulfide bonds and 6 N-linked glycosylation sites (mouse 7). The N-terminal 153 amino acid region of TPO shows structural and amino acid sequence homology to erythropoietin and a pair of arginines (potential cleavage site) separating it from the highly glycosylated carboxyterminal domain.

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

Thrombopoietin (TPO) plays a critical role in megakaryocyte proliferation and differentiation. Using various cultured cell lines, several recent studies have implicated the mitogen-activated protein kinase (MAPK) pathway in megakaryocyte differentiation. In the study reported here, we examined the role played

The JAK2V617F allele has recently been identified in patients with polycythemia vera (PV), essential thrombocytosis (ET), and myelofibrosis with myeloid metaplasia (MF). Subsequent analysis has shown that constitutive activation of the JAK-STAT signal transduction pathway is an important pathogenetic event

Neuro-inflammation plays a key role in the occurrence and development of postoperative cognitive dysfunction (POCD). Although S100A8 and Toll-like receptor 4 (TLR4) have been increasingly recognized to contribute to neuro-inflammation, little is known about the interaction between S100A8 and TLR4/MyD88
