In bovine oviduct cells 17beta-oestradiol can induce the synthesis of leukaemia inhibitory factor (LIF), a glycoprotein essential for embryo implantation. Therefore substances which are structurally similar to 17beta-oestradiol and possess oestrogenic activity may also modulate LIF synthesis and influence the reproductive process. We used primary cultures of bovine and human oviduct cells (epit...

BACKGROUND Myocardial infarction (MI) is a leading cause of cardiac morbidity and mortality in many countries; however, the treatment of MI is still limited. METHODS AND RESULTS We demonstrate a novel gene therapy for MI using leukemia inhibitory factor (LIF) cDNA. We injected LIF plasmid DNA into the thigh muscle of mice immediately after inducing MI. Intramuscular injection of LIF cDNA resu...

Neural stem cells (NSC) self-renew and generate specialized cell types. There are reports indicating that Notch and Leukemia Inhibitory Factor (LIF) signaling are involved in cell determination of NSC, either preventing differentiation or promoting astrocytic fate. In this work, we aimed to compare the astrocytogenic effect of activated Notch with that induced by LIF. To this end, rat cerebral ...

Pancreatic ductal adenocarcinoma (PDAC) is characterized by extensive stroma and pathogenic modifications to the peripheral nervous system that elevate metastatic capacity. In this study, we show that the IL6-related stem cell-promoting factor LIF supports PDAC-associated neural remodeling (PANR). LIF was overexpressed in tumor tissue compared with healthy pancreas, but its receptors LIFR and g...

Leukaemia inhibitory factor (LIF), a pleiotropic cytokine, is implicated in blastocyst implantation in mice and maintains the development of ovine embryos in culture. Previously, LIF mRNA and protein were demonstrated in the endometrium throughout the oestrous cycle and early pregnancy in the ewe. In this study pregnant ewes were passively immunised against human recombinant LIF with polyclonal...

Neuronal adaptation as well as interdischarge interval correlations have been shown to be functionally important properties of physiological neu-rons. We explore the dynamics of a modified leaky integrate-and-fire (LIF) neuron, referred to as the LIF with threshold fatigue, and show that it reproduces these properties. In this model, the postdischarge threshold reset depends on the preceding se...

Background: Leukemia inhibitory factor (LIF) is a 45-56 kDa glycoprotein that has an important role in proliferation and embryo implantation. Its effect on oocyte maturation and how to exert the function remained to be elucidated. Methods: Immature mice superovulated with human menopausal gonadotropin and germinal vesicle (GV) oocytes were obtained from ovary 48 hours after. GV oocytes were cul...

Background and purpose: Oligodendrocytes are responsible for myelin synthesis in the central nervous system (CNS). Olig1 and Olig2 play an important role in regulating the development of oligodendrocyte precursor cells (OLPs). Myelin basic protein (MBP) is the main component of myelin sheath. Leukemia inhibitory factor (LIF) has an important role in myelination and pathology of multiple scleros...
