The PTH/PTHrP receptor (PTHR1) plays an essential role in skeletal development and mediates many other functions of PTH and PTHrP. Human PTHR1 gene transcription is controlled by three promoters, P1-P3. The most proximal promoter, P3, is active in bone and osteoblast-like cell lines and accounts for the majority of renal transcripts in adults. We have(More)
This study was designed to investigate the chronic cardiotoxic potential of SM-5887 and a possible deteriorating effect of SM-5887 on low-grade cardiotoxicity pre-induced by doxorubicin in beagle dogs. In the chronic treatment, beagle dogs of each sex were given intravenously once every 3 weeks, either a sublethal dose of doxorubicin (1.5 mg/kg) or SM-5887(More)
The mechanism by which adult neural stem cells (NSCs) are established during development is unclear. In this study, analysis of cell cycle progression by examining retention of a histone 2B (H2B)-GFP fusion protein revealed that, in a subset of mouse embryonic neural progenitor cells (NPCs), the cell cycle slows between embryonic day (E) 13.5 and E15.5(More)
Mutation analysis of FBXW7 and NOTCH1 genes was performed in 55 T cell acute lymphoblastic leukaemia (T-ALL) and 14 T cell non-Hodgkin lymphoma (T-NHL) patients who were treated on the Japan Association of Childhood Leukaemia Study (JACLS) protocols ALL-97 and NHL-98. FBXW7 and/or NOTCH1 mutations were found in 22 (40.0%) of 55 T-ALL and 7 (50.0%) of 14(More)
BACKGROUND Previous Japanese studies of childhood B-cell non-Hodgkin lymphoma (B-NHL) have shown a favorable outcome, though the study size was too small to effectively assess the efficacy and safety of treatment for childhood B-NHL. PROCEDURE We performed a nation-wide prospective B-NHL03 study to assess the efficacy and safety of short-pulse intensive(More)
The clinical characteristics and prognostic relevance of acute myeloid leukaemia (AML) with myelodysplastic features remains to be clarified in children. We prospectively examined 443 newly diagnosed patients in a multicentre clinical trial for paediatric de novo AML, and found 'AML with myelodysplasia-related changes' (AML-MRC) according to the 2008 World(More)
PURPOSE Evidence suggests an association between aberrant mitochondrial dynamics and cardiac diseases. Because myocardial metabolic deficiency caused by insulin resistance plays a crucial role in heart disease, we investigated the role of dynamin-related protein-1 (DRP1; a mitochondrial fission protein) in the pathogenesis of myocardial insulin resistance.(More)
BACKGROUND In recent years, the population of elderly people in Japan with dementia has increased. Detection of cognitive impairment in the early stages is important for adequate treatment, care, and prevention. AIM To investigate whether the reliability and validity of the instrument would carry over to a different population and language before using it(More)
BACKGROUND This study aimed to examine the contribution made by the change in mortality from malignant neoplasms to the life expectancy at birth, observed during the years 1965-1995 in Japan. METHODS We used data on the population and number of deaths by cause, age and sex in 1965, 1975, 1985 and 1995. The contribution of different ages and causes of(More)
