During pre-implantation mouse development, embryos form blastocysts with establishment of the first two cell lineages: the trophectoderm (TE) which gives rise to the placenta, and the inner cell mass (ICM) which will form the embryo proper. Differentiation of TE is regulated by the transcription factor Caudal-related homeobox 2 (Cdx2), but the mechanisms(More)
Dimethylarsinic acid (DMA(V)) is carcinogenic to the rat urinary bladder when administered at high doses in the diet or drinking water. At a dietary dose of 100 ppm (microg/g), it produces cytotoxicity within 6 h and increased proliferation (hyperplasia) by 7 days of administration. We hypothesize that formation of the reactive organic intermediate(More)
BACKGROUND AND AIMS Cholangiocarcinoma (CCA) is considered a contraindication for liver transplantation by most liver transplant centers. The aim of this study has been to report our results as well as to explore factors that influence patient survival after liver transplantation for CCA. PATIENTS All transplant patients with CCA in Norway, Sweden and(More)
PURPOSE Esophageal squamous cell carcinoma (ESCC) frequently shows a poor prognosis because of the occurrence of systemic metastasis, mainly via lymphatic vessels. Valosin-containing protein (VCP) has been shown to be associated with antiapoptotic function and metastasis via activation of the nuclear factor-kappaB signaling pathway. In the present study, we(More)
SUMMARY Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) rarely affects the intracranial region without involvement of other sites. We report the case of a 68-year-old woman with isolated Rosai-Dorfman disease of the frontal dura. She presented with a new onset seizure. Initial MR imaging showed subtle mild change in the left frontal(More)
A 2-year-old East Friesian sheep imported from Australia exhibited severe anemia after contagious pustular dermatitis in Hokkaido, Japan. Hemoplasma infection was confirmed in blood smears. Both Mycoplasma ovis and 'Candidatus Mycoplasma haemovis' were detected by PCR and sequence analyses. In the epidemiological analysis, dual pathogens were detected in 6(More)
PURPOSE Akt is a serine/threonine kinase that plays a central role in tumorigenesis. Among the members of Akt family, Akt2 is associated with the development of human cancers. The present study was designed to clarify the prognostic significance of Akt2 and activated Akt expression in pancreatic ductal adenocarcinoma (PDAC). In addition, activated(More)
The cell population and the activity of the organizer change during the course of development. We addressed the mechanism of mouse node development via an analysis of the node/notochord enhancer (NE) of Foxa2. We first identified the core element (CE) of the enhancer, which in multimeric form drives gene expression in the node. The CE was activated in(More)
Vertebrate Wnt proteins activate several distinct pathways. Intrinsic differences among Wnt ligands and Frizzled (Fzd) receptors, and the availability of pathway-specific coreceptors, LRP5/6, and Ror2, affect pathway selection. Here, we show that a secreted glycoprotein, Cthrc1, is involved in selective activation of the planar cell polarity (PCP) pathway(More)
