Background: The transmembrane protein gp130 plays a central role in cytokine action as a signal transducing receptor subunit common to all interleukin-6 type cytokines. The expression of IL-6 is significantly increased near the implantation site in tubes with ectopic gestation as compared with normal.Thus, current study was designed to investigated the expression of gp130 in fallopian tubes wit...

Two of the most potent cytokines that regulate anterior pituitary cell function are leukemia inhibitory factor and IL-6. These and others like IL-11 and ciliary neurotrophic factor are referred to as the gp130 cytokines because they share the gp130 glycoprotein as a common receptor initial signal transducer. We and others have shown that gp130 cytokines and their receptors are expressed and fun...

The cytokine receptor gp130 is the common signaling subunit of receptors used by the interleukin (IL)-6 cytokine family. gp130 is widely expressed in breast cancer cell lines and primary tumors. The role of gp130 in breast cancer in vivo is unknown. To study the effect of gp130 inhibition in breast cancer, endogenous gp130 signaling in breast cancer cell lines was blocked with a dominant-negati...

INTRODUCTION Bone marrow transplantation (BMT) is a complex process regulated by different cytokines and growth factors. The pleiotropic cytokine IL-6 (Interleukin-6) and related cytokines of the same family acting on the common signal transducer gp130 are known to play a key role in bone marrow (BM) engraftment. In contrast, the exact signalling events that control IL-6/gp130-driven haematopoi...

Inflammation and vascular remodeling are hallmarks of atherosclerosis, hypertension, and restenosis after angioplasty. Here we investigated the role of the hepatocyte gp130-dependent systemic acute phase response on vascular remodeling after carotid artery ligation. Mice with a hepatocyte-specific gp130 knockout on an apolipoprotein E(-/-) background (gp130-) were compared with control mice (gp...

The receptor gp130 is used by the interleukin-6 (IL-6)-type cytokines, which include IL-6 and leukaemia-inhibitory factor (LIF). To investigate the role of the three extracellular membrane-proximal fibronectin-type-III-like (FNIII) modules of gp130 and the related receptor for granulocyte colony-stimulating factor (G-CSFR) in cytokine signal transduction we have transfected into murine myeloid ...

OBJECTIVE gp130 cytokines are placed as auto-paracrine regulators of pituitary function, since they, as well as their receptors, have been shown to be expressed in and to act in normal and tumoral anterior pituitary cells. The objective of this work was to study their involvement in a model that shows the interaction between different cellular types that participate in a tumorigenic process. ...

After nerve injury, adult sensory neurons can regenerate peripheral axons and reconnect with their target tissue. Initiation of outgrowth, as well as elongation of neurites over long distances, depends on the signaling of receptors for neurotrophic growth factors. Here, we investigated the importance of gp130, the signaling subunit of neuropoietic cytokine receptors in peripheral nerve regenera...

Interleukin 6 (IL-6), a pleiotropic cytokine, functions in cells through its interaction with its receptor complex, which consists of two ligand-binding alpha subunits and two signal-transducing subunits known as gp130. There is a wealth of studies on signals mediated by gp130, but its downregulation is less well understood. Here we found that IL-6 stimulation induced lysosome-dependent degrada...
