    FAMILY
  • LIF/OSM (oncostatin M) family
  • CATEGORY signaling cytokine
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • cholinergic neuronal differentiation factor
  • inducing macrophage differentiation and in conjunction with BMP2 acting in synergy on primary fetal neural progenitor cells to induce astrocytes
  • inducing multi-lineage differentiation of adult stem-like cells in kidney via cadherin 16
  • plays a central role in the control of uterine implantation
  • reduces neurogenesis in the olfactory bulb and subventricular zone by acting directly on neural stem cells and promote neural stem cells self-renewal, preventing the emergence of more differentiated cell types
  • involved in the control of osteoclast survival and size
  • with IL11 regulated endometrial epithelial cell adhesion (Marwood 2009)
  • potential role for LIF in the melanoma-induced bone metastasis possibly through the stimulation of osteoclastogenesis (Maruta 2009)
  • inhibits osteoblast development at least in part by stimulating high molecular weight HA synthesis through HAS2 (Falconi 2007)
  • playing a role in mesenchymal stem cells mediated immunosuppression (Nasef 2008)
  • might be one of the reasons that cause patients with salpingitis to be more susceptible to tubal pregnancy and might be involved in the implantation process of tubal pregnancy (JI 2009)
  • with CNTF, LEP, IL6, participate to the complex control of the reproductive function by affecting the development and function of the hypothalamus-pituitary system at different ontogenic times and anatomical sites (Dozio 2009)
  • CELLULAR PROCESS cell life, proliferation/growth
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    cell-cell singaling cooperatively with BMP2 through a complex formed by STAT3, MADH1 bridged by EP300 and the subsequent induction of astrocytes differentiation
    a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with HAS2 (arrests osteoblast differentiation by altering HAS2 content of the extracellular matrix) (Falconi 2007)

    Therapy target
  • may be useful, in combination with other factors, in promoting regeneration in the adult brain
  • targeting IL11 and LIF may be useful in regulating fertility by either enhancing or blocking implantation (Marwood 2009)
  • potentially effective drug target in the treatment of bone metastasis in melanoma (Maruta 2009)
