Target Background

Signal-transducing molecule. May have a common pathway with IL6ST. The soluble form inhibits the biological activity of LIF by blocking its binding to receptors on target cells.
Gene References into Functions
  1. High levels of LIFR in colorectal cancer (CRC) facilitated proliferation and migration of endothelial cells, resulting in an increase in angiogenic activity. Moreover, IL-8 was found to play a role in the LIFR induced angiogenesis. IL-8 levels were correlated with LIFR levels in CRC tissues, whereas depletion of IL-8 led to a reduced angiogenic activity of LIFR in CRC cells. PMID: 29751081
  2. These data indicate that miR-377-3p suppressed adipogenesis of human bone marrow mesenchymal stem cells by targeting LIFR, which provides novel insights into the molecular mechanism of miRNA-mediated cellular differentiation. PMID: 29959592
  3. High expression of LIFR is associated with preeclampsia. PMID: 29363569
  4. LIFR attenuates tumor metastasis by suppressing YAP expression, suggesting that LIFR may serve as a potential target for clear cell renal cell carcinoma treatment. PMID: 29902078

  7. Expression of cancer-specific glycan epitopes represents an excellent opportunity for diagnostics and potentially specific detection of tumors. Here, we report four proteins (LIFR, CE350, VP13A, HPT) found in sera from pancreatic cancer patients carrying aberrant glycan structures as compared to those of controls. PMID: 28244758
