-PGJ2 enhances platelet production from megakaryocytes
Thrombocytopenia is a critical problem that occurs in many hematologic diseases, as well as after cancer therapy and radiation exposure. Platelet transfusion is the most commonly used therapy but has limitations of alloimmunization, availability, and expense. Thus, the development of safe, small, molecules to enhance platelet production would be advantageous for the treatment of thrombocytopeni...
متن کاملBiosynthesis of 15-deoxy-∆-PGJ2 and the ligation of PPARγ
945 Introduction The PPAR nuclear hormone transcription factors heterodimerize with retinoic acid receptors to regulate expression of distinct gene cassettes (1, 2). Although three PPAR isotypes (α, δ, and γ) have been well characterized, the identity of their natural ligands remains controversial (3–6). PPARγ is expressed predominantly in adipose tissue, colon and macrophages, and to a lesser ...
متن کاملLactoferrin inhibits platelet production from human megakaryocytes in vitro.
The mechanism of megakaryopoiesis, proplatelet formation (PPF) and platelet (PLT) production is not fully elucidated. Lactoferrin (LF) has been reported to have many biological functions including cell proliferation and differentiation, and the LF receptor is present on megakaryocytic cells. In the present study, we examined the effect of human LF (hLF) on PLT production from primary megakaryoc...
متن کامل15-deoxy-Delta 12,14-PGJ2 induces IL-8 production in human T cells by a mitogen-activated protein kinase pathway.
Mast cells, platelets, and some macrophages are abundant sources of PGD(2) and its active metabolite 15-deoxy-Delta(12,14)-PGJ(2) (15-d-PGJ(2)). The lipid mediator 15-d-PGJ(2) regulates numerous processes, including adipogenesis, apoptosis, and inflammation. The 15-d-PGJ(2) has been shown to both inhibit as well as induce the production of inflammatory mediators such as TNF-alpha, IL-1beta, and...
متن کامل15-deoxy-Δ12,14-PGJ2 promotes inflammation and apoptosis in cardiomyocytes via the DP2/MAPK/TNFα axis
BACKGROUND Prostaglandins (PGs), lipid autacoids derived from arachidonic acid, play a pivotal role during inflammation. PGD₂ synthase is abundantly expressed in heart tissue and PGD₂ has recently been found to induce cardiomyocyte apoptosis. PGD₂ is an unstable prostanoid metabolite; therefore the objective of the present study was to elucidate whether its final dehydration product, 15-deoxy-Δ...
