Wnt signaling has an important role in both embryonic development and tumorigenesis. beta-Catenin, a key component of the Wnt signaling pathway, interacts with the TCF/LEF family of transcription factors and activates transcription of Wnt target genes. Here, we identify a novel beta-catenin-interacting protein, ICAT, that was found to inhibit the(More)
Lung metastasis has a great influence on the prognosis of patients with osteosarcoma. We previously established two high-metastatic sublines, M112 and M132, from the HuO9 human osteosarcoma cell line by in vivo selection. In this study, we newly isolated a high-metastatic subline, H3, and three low-metastatic sublines, L6, L12 and L13, from HuO9 by the(More)
The serum concentration of hepatocyte growth factor (HGF) was examined in 34 patients with metastatic breast cancer. Although no significant difference was observed between HGF concentration and the site of metastasis, serum HGF levels were slightly higher in patients with liver metastasis and in patients with multiple metastatic sites than in patients with(More)
BACKGROUND Advanced abdominal malignancies are occasionally invasive for the major blood vessels, such as the portal vein (PV), inferior vena cava (IVC), and major hepatic veins (HVs), and complete removal of the tumors is required for patients undergoing vascular resection and reconstruction. We used left renal vein (LRV) grafts for vascular reconstruction(More)
Inhibitor of beta-catenin and T cell factor (ICAT) inhibits Wnt signaling by interfering with the interaction between beta-catenin and T cell factor. Here we show that ICAT(-/-) embryos exhibit malformation of the forebrain and craniofacial bones and lack the kidney. Analysis of the neuronal differentiation of embryonic stem cells revealed that Wnt3a(More)
In the anterior pituitary gland, inflammatory mediators regulate cell function through an immuno-endocrine pathway. Recent studies have shown that undifferentiated stem cells act as immunomodulators. These studies prompted us to establish a progenitor cell line from the bovine anterior pituitary gland and to detail its function. First, we localised(More)
Following a simple cholecystectomy, a 63-year-old woman with gallstones was histologically diagnosed as having minute squamous cell carcinoma of the gallbladder. A laparotomy revealed a small, firm nodule that appeared to be an adenoma, which was palpated in the fundus of the gallbladder. The resected gallbladder contained 37 small stones and a small and(More)
We report the cloning of a human homolog of the yeast OGGC1 gene, which encodes a DNA glycosylase that excises an oxidatively damaged form of guanine, 8-hydroxyguanine (also known as 7,8-dihydro-8-oxoguanine). Since the deduced amino acid sequence (68 amino acids) of a human expressed sequence tag, N55394, matched a short stretch of yeast OGG1 protein with(More)
Four (1.2%) out of 321 patients required percutaneous transhepatic gallbladder drainage (PTGBD) following cardiovascular surgery. Cholecystitis was initially suspected based upon the occurrence of postoperative fever and the results of abdominal X-ray films. The main physical finding was tenderness of the right upper quadrant abdomen in all patients.(More)
Nuclear magnetic resonance spectroscopy has detected elevated phosphocholine levels in human tumor tissues and cells, and in cells that were transformed with the activated Ha-ras gene and stimulated in vitro with growth-promoting factors such as platelet-derived growth factor, epidermal growth factor, and phorbol ester. However, the mechanism of the(More)
