This study reports on leukemia inhibitory factor (LIF) in human articular connective tissues. Biologically active LIF is present in synovial fluids from patients with osteoarthritis and at higher titers in samples from patients with rheumatoid arthritis. Cultured human synoviocytes and articular chondrocytes produced biologically active LIF and synthesized and secreted LIF proteins that migrate...

The distribution and regulation of leukemia inhibitory factor (LIF) and its receptor (LIFR) in human lung tissue is unknown. We recently found that LIF was immunolocalized to several cell types in human airways, and that exogenous LIF modulated neural and contractile responses of explanted airways. The present study aimed to determine the cellular distribution and regulation of gene transcripts...

Mg/Ti order/disorder and the lattice dynamics of orthorhombic pseudobrookite-type MgTi2O5 have been studied by experiment and modeling. A mechanochemical activation by high speed ball milling allowed us to synthesize pure MgTi2O5 from MgO and TiO2 anatase at a comparatively low temperature of 1173K. The Mg/Ti order of MgTi2O5 was characterized by X-ray diffraction and Raman spectroscopy. Densit...

Background: HOXA11 and leukemia inhibitory factor (LIF) and basic transcriptional element binding protein1 (BTEB1) are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. In this case-control study, the expression pattern of these mRNA was evaluated in patients with endometriosis at the time of implantatio...

Background: Leptin has been implicated in the differentiation and proliferation of hematopoietic cells. Leukemia inhibitory factor (LIF) may play an important role, along with Interleukin-6 (IL-6) and granulocyte colony stimulating factor (G- CSF), in the regulation of early hematopoietic stem cells. The aim of the study was to evaluate serum level of leptin, LIF, and IL-6 in myeloid leukemia p...

Leukemia inhibitory factor (LIF) is a pleiotropic IL-6 family cytokine and its maternal uterine expression is critical for mouse blastocyst implantation. In the golden hamster (Mesocricetus auratus), although the blastocyst hatching phenomenon is quite interesting and LIF is shown to regulate hatching, information is not available on the embryonic and uterine expression of LIF and hormonal regu...

BACKGROUND This pilot trial was designed to determine if an optimal dose of Technosphere(®) insulin (TI) inhalation powder (MannKind Corp., Valencia, CA) could be used regardless of variation in meal carbohydrate (CHO) content. SUBJECTS AND METHODS In total, eight subjects (seven men, one woman) with type 2 diabetes were enrolled. Subjects underwent dose optimization meal challenge (MC) visit...

The cytokine leukemia inhibitory factor (LIF) is expressed by skeletal muscle and induces proliferation of myoblasts. We hypothesized that LIF is a contraction-induced myokine functioning in an autocrine fashion to activate gene regulation of human muscle satellite cell proliferation. Skeletal muscle LIF expression, regulation, and action were examined in two models: 1) young men performing a b...

This Phase I dose-escalation clinical trial of a lyophilized formulation of titanocene dichloride (MKT4) was conducted to determine the maximum tolerated dose, the dose-limiting toxicity (DLT), and pharmacokinetics of titanium (Ti) after a single i.v. infusion of MKT4. Forty patients with refractory solid malignancies were treated with a total of 78 courses. Using a modified Fibonacci scheme, 1...

We used a simple and efficient method to construct a bicistronic eukaryotic expression vector pIRES2-LIF-NT-3. The leukemia inhibitory factor (LIF) and neurotrophin-3 (NT-3) genes were obtained from the genomic DNA of human peripheral blood mononuclear cells by polymerase chain reaction. The LIF cDNA fragment was inserted into the multiple cloning sites of a vector containing internal ribosome ...
