Oncostatin M and leukemia inhibitory factor do not use the same functional receptor in mice.
Oncostatin M (OSM) and leukemia inhibitory factor (LIF) are members of the interleukin-6 (IL-6) subfamily of cytokines that use a common signal transducer gp130. Human OSM (hOSM) and LIF share a functional high-affinity receptor that is composed of gp130 and LIF receptor beta subunit (LIFRbeta). A second high-affinity receptor for hOSM was recently found to be formed by gp130 and the hOSM recep...
متن کاملDevelopmental expression pattern of oncostatin M receptor β in mice
Oncostatin M (OSM), which is predominantly expressed in bone marrow, is a member of the interleukin-6 family of cytokines, and appears to play important roles in hematopoiesis and the development of the liver. Recently, specific b subunit of OSM receptor (OSMRb) was isolated from LO cells originated from aorta-gonad-mesonephros (AGM) region. In this study, we performed in situ hybridization to ...
متن کاملReceptor subunit-specific action of oncostatin M in hepatic cells and its modulation by leukemia inhibitory factor.
The related cytokines, interleukin-6 (IL-6), oncostatin M (OSM), and leukemia inhibitory factor (LIF) direct the formation of specific heteromeric receptor complexes to achieve signaling. Each complex includes the common signal-transducing subunit gp130. OSM and LIF also recruit the signaling competent, but structurally distinct OSMRbeta and LIFRalpha subunits, respectively. To test the hypothe...
متن کاملSignal transduction of IL-6, leukemia-inhibitory factor, and oncostatin M: structural receptor requirements for signal attenuation.
Stimulation of the IL-6R complex leads to Src homology domain containing tyrosine phosphatase 2 (SHP2) recruitment to the receptor subunit gp130 and its subsequent tyrosine phosphorylation. SHP2 is a two-SH2 domain-containing protein tyrosine phosphatase that is activated by many cytokines and growth factors. SHP2 counteracts the activation of transcription factors of the STAT family and the in...
متن کاملOncostatin M promotes bone formation independently of resorption when signaling through leukemia inhibitory factor receptor in mice.
Effective osteoporosis therapy requires agents that increase the amount and/or quality of bone. Any modification of osteoclast-mediated bone resorption by disease or drug treatment, however, elicits a parallel change in osteoblast-mediated bone formation because the processes are tightly coupled. Anabolic approaches now focus on uncoupling osteoblast action from osteoclast formation, for exampl...
