mTORC1 promotes cell growth in response to nutrients and growth factors. Insulin activates mTORC1 through the PI3K-Akt pathway, which inhibits the TSC1-TSC2-TBC1D7 complex (the TSC complex) to turn on Rheb, an essential activator of mTORC1. However, the mechanistic basis of how this pathway integrates with nutrient-sensing pathways is unknown. We(More)
BACKGROUND AND OBJECTIVES The clear delineation between tumor and normal tissue is ideal for real-time surgical navigation imaging. We present a novel indocyanine green (ICG) fluorescence imaging technique to visualize hepatocellular carcinoma (HCC). METHODS Ten patients with solitary HCC underwent hepatectomy between February and September 2007 at Osaka(More)
In this study, we examined the biological action of IL-17 on human non-small cell lung cancer (NSCLC). Although IL-17 had no direct effect on the in vitro growth rate of NSCLC, IL-17 selectively augmented the secretion of an array of angiogenic CXC chemokines, including CXCL1, CXCL5, CXCL6, and CXCL8 but not angiostatic chemokines, by three different NSCLC(More)
OBJECTIVE To evaluate both the feasibility and efficacy of our combined therapy, which consisted of preoperative chemoradiation, surgery, and postoperative liver perfusion chemotherapy (LPC) for patients with T3 (extended beyond the pancreatic confines) cancer of the pancreas. SUMMARY BACKGROUND DATA Because of the high incidence of local recurrence and(More)
BACKGROUND The aim of our study was to examine the feasibility of allogeneic uterine transplantation in a large animal model. METHODS We performed heterotopic uterine transplants in genetically defined mini-pigs. Immunosuppression was tacrolimus administered intravenously for the first 12 days posttransplantation followed by oral cyclosporine maintenance(More)
Disseminated intravascular coagulation (DIC) is the most common complication of solid tumours. In this study, the effectiveness of three polysaccharide anticoagulants (PSAs), at therapeutic doses, at inhibiting solid tumour growth was investigated. Mice with tumour xenografts were subcutaneously injected with either unfractionated heparin (UFH; 200 units(More)
To examine the effects of rhinovirus (RV) infection on the adherence of Streptococcus pneumoniae to human tracheal epithelial cells, cells were infected with RV-14, and S. pneumoniae were added to the culture medium. The number of S. pneumoniae adhering to epithelial cells increased after RV infection. Y-24180, a specific inhibitor of the(More)
Interleukin-17 (IL-17) is a CD4 T cell-derived proinflammatry and proangiogenic cytokine. In this study, we investigated the effects of this cytokine on vascular endothelial cell growth induced by a well-known direct angiogenic factor bFGF, HGF, VEGF, CXCL5/ENA-78 or CXCL8/IL-8. While a wide range of doses of IL-17 alone did not show the ability to(More)
Based on the results of cytological studies, it has been assumed that Cyanidioschyzon merolae does not contain actin genes. However, Southern hybridization of C. merolae cell-nuclear DNA with a yeast actin-gene probe has suggested the presence of an actin gene in the C. merolae genome. In the present study, an actin gene was isolated from a C. merolae(More)
Because there is no effective treatment for this retinal degeneration, potential application of cell-based therapy has attracted considerable attention. Several investigations support that bone marrow mesenchymal stem cells (MSCs) can be used for a broad spectrum of indications. Bone marrow MSCs exert their therapeutic effect in part by secreting trophic(More)
