CNTF mediates its function by activating a tripartite receptor comprising the CNTF receptor alpha chain (CNTFRalpha), the leukemia inhibitory factor receptor beta chain (LIFRbeta) and gp130.
|
6 |
15542451
|
Rat and human CNTF differ in their fine specificities: in addition to CNTFR, rat CNTF has been shown to activate the LIFR (a heterodimer of LIFRbeta and gp130), whereas human CNTF can bind and activate a tripartite receptor comprising the IL-6 receptor alpha chain (IL-6Ralpha) and LIFR.
|

15542451
|
Recombinant mouse CNTF was active and showed a high level of specificity for mouse CNTFR.
|
8 |
15542451
|
Recombinant mouse CNTF is therefore specific for CNTFR and as such represents a useful tool with which to study CNTF in mouse models.
|
9 |

|
It appears well suited for the comparative evaluation of CNTF and the two additional recently discovered CNTFR ligands, cardiotrophin-like cytokinecytokine-like factor-1 and neuropoietin.

Leukemia inhibitory factor regulates trophoblast giant cell differentiation via Janus kinase 1-signal transducer and activator of transcription 3-suppressor of cytokine signaling 3 pathway.
|
16 |
18451094
|
Suppressor of cytokine signaling 3 (SOCS3) inhibits leukemia-inhibitory factor (LIF) signaling and acts as a negative regulator.
|
17 |
18451094
|
Deletion of SOCS3 causes embryonic lethality because of placental failure, and genetic reduction of LIF or the LIF receptor (LIFR) in SOCS3-deficient mice rescues placental defects and embryonic lethality; this indicates that SOCS3 is an essential inhibitor of LIFR signaling.
|
18 |
18451094
|
However, the downstream signaling molecule that acts as a link between the LIFR and SOCS3 has not been identified.
|
19 |
18451094
|
The administration of LIF to SOCS3-heterozygous pregnant mice promotes trophoblast giant cell differentiation and accelerates placental failure in SOCS3-deficient mice.
|

|
SOCS3-deficient trophoblast stem cells show enhanced and prolonged signal transducer and activator of transcription 3 (Stat3) activation by LIF stimulation.
|
21 |
18451094
|
Further, in the trophoblasts of SOCS3-deficient placenta and differentiating cells from the choriocarcinoma-derived cell line Rcho-1 cells, constitutive activation of Stat3 is observed.
|
22 |
18451094
|
The forced expression of SOCS3, dominant-negative Stat3, and dominant-negative Janus kinase 1 (JAK1) in Rcho-1 cells significantly suppressed the trophoblast giant cell differentiation of these cells.
|
23 |
18451094
|
Finally, JAK1 deficiency rescues placental defects and embryonic lethality in SOCS3-deficient mice.
|
24 |
18451094
|
These results indicate that the LIFR signaling is finely coordinated by JAK1, Stat3, and SOCS3 and regulates trophoblast giant cell differentiation.
|
25 |

In addition, these data establish that LIFR-JAK1-Stat3-SOCS3 signaling is an essential pathway for the regulation of trophoblast giant cell differentiation.

The mRNA and protein expressions of LIF and its receptor (LIFR) were measured in skeletal muscle biopsies from healthy individuals and patients with type 2 diabetes by use of qPCR and Western blot.
|
60 |
22649064
|
LIF signaling and response were studied following administration of recombinant LIF and siRNA knockdown of suppressor of cytokine signaling (SOCS)3 in myoblast cultures established from healthy individuals and patients with type 2 diabetes.
|
61 |
22649064
|
LIF and LIFR proteins were increased in both muscle tissue and cultured myoblasts from diabetic patients.
|
62 |
22649064
|
Nonetheless, in the diabetic myoblasts, LIF-induced phosphorylation of signal transducer and activator of transcription (STAT)1 and STAT3 was impaired.
|
63 |
22649064
|
The deficient response to LIF administration in the diabetic myoblasts was further emphasized by a lack of increase in LIF-stimulated cell proliferation and a decreased LIF-stimulated induction of the proliferation-promoting factors cyclin D1, JunB, and c-myc.
|
64 |
22649064
|
SOCS3 protein was upregulated in diabetic myoblasts, and knockdown of SOCS3 rescued LIF-induced gene expression in diabetic myoblasts, whereas neither STAT1 or STAT3 signaling nor proliferation rate was affected.
|
65 |
22649064
|
In conclusion, although LIF and LIFR proteins were increased in muscle tissue and myoblasts from diabetic patients, LIF signaling and LIF-stimulated cell proliferation were impaired in diabetic myoblasts, suggesting a novel mechanism by which muscle function is compromised in diabetes.
