Human leukemia inhibitory factor (hLIF) is a multifunctional cytokine that is essential for maintaining the pluripotency of embryonic stem cells. hLIF may be also be useful in aiding fertility through its effects on increasing the implantation rate of fertilized eggs. Thus these applications in biomedical research and clinical medicine create a high demand for bioactive hLIF. However, productio...

Leukemia inhibitory factor (LIF) is a pleiotropic cytokine whose activities appear to be mediated through a single heterodimeric receptor complex. Human LIF (hLIF) can bind to and activate mouse LIF (mLIF) receptors but mLIF is unable to bind to hLIF receptors. Cross-species competition of mLIF and hLIF for binding to the mLIF receptor was found to be dependent on which ligand was used as the r...

Since interferon administration in the treatment of some malignant conditions has been reported to cause leukopenia, we studied the effects of human leukocyte interferon preparation (HLIF) on myelopoiesis in vitro. The continual presence of HLIF in semisolid agar cultures caused a progressive decline in colony and a rise in cluster incidence with increasing concentrations of interferon. The tot...

High-Level Information Fusion (HLIF) utilizes techniques from Low-Level Information Fusion (LLIF) to support situation/impact assessment, user involvement, and mission and resource management (SUM). Given the unbounded analysis of situations, events, users, resources, and missions; it is obvious that uncertainty is manifested by the nature of application requirements. In this panel, we seek dis...

OBJECTIVE Leukemia inhibitory factor (LIF) plays important roles in cellular proliferation, growth promotion and differentiation of various types of target cells. In addition, LIF influences bone metabolism, cachexia, neural development, embryogenesis and inflammation. Human LIF (hLIF) is an essential growth factor for the maintenance of mouse embryonic stem cells (ESCs) and induced pluripotent...

Leukemia inhibitory factor (LIF) is a cytokine that shows conflicting effects on in vitro produced (IVP) bovine embryos. Bovine LIF (bLIF) has been cloned and used in culture, but there is no commercially available bLIF. Thus, researchers use human LIF (hLIF) to supplement the culture medium for bovine embryos because of its greater sequence homology compared to murine LIF (mLIF). We compared t...

In an increasingly interconnected world information comes from various sources, usually with distinct, sometimes inconsistent semantics. Transforming raw data into high-level information fusion (HLIF) products, such as situation displays, automated decision support, and predictive analysis, relies heavily on human cognition. There is a clear lack of automated solutions for HLIF, making such sys...

Complementary DNA (cDNA) is valuable for investigating protein structure and function in the research of life science, but it is difficult to obtain by traditional reverse transcription. In this study, we employed a novel strategy to clone the human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA directly isolated from the mucous membrane of mouth. The hLIF sequence can be acquired...

The effect of human leukemia inhibitory factor (hLIF) on the development of atherosclerosis was investigated in an experimental animal model. Two conditions were examined: one in which lesions could arise because of the influence of both "injury" (cuffed vessel) and diet and one in which only the effect of diet could be significant in other areas of the vasculature (aorta). At time zero, the ri...
