Calcium plays a critical part in the regulation of cell growth, and growth factors stimulate calcium entry into cells through calcium-permeable channels. However, the molecular nature and regulation of calcium-permeable channels are still unclear at present. Here we report the molecular characterization of a calcium-permeable cation channel that is(More)
Familial adenomatous polyposis coli (FAP) is a disease characterized by the development of multiple colorectal adenomas, and affected individuals carry germline mutations in the APC gene. With the use of a conditional gene targeting system, a mouse model of FAP was created that circumvents the embryonic lethality of Apc deficiency and directs Apc(More)
We examined the afferent projections to the subnuclei of the interpeduncular nucleus (IPN) in the rat by means of retrograde and anterograde transport of wheat germ agglutinin conjugated to horseradish peroxidase (WGA-HRP). We observed locations of retrogradely labeled cells following injections of WGA-HRP into the IPN, and distributions of anterogradely(More)
The present study was conducted to examine the ability of insulin receptor to activate the calcium signaling system in Chinese hamster ovary (CHO) cells expressing human insulin receptor (CHO-IR cells). In these cells, insulin evoked the elevation of cytoplasmic free calcium concentration, [Ca2+]c, measured by using fura-2. Insulin-induced increase in(More)
The somatotopic representation of facial muscles within the facial nucleus was investigated by means of the retrograde horseradish peroxidase and cell degeneration techniques in the mouse. The nasolabial muscle is represented in the dorsolateral, lateral, and dorsal intermediate subnucleus; the mentalis muscle, in the ventral intermediate subnucleus; the(More)
Nuclear receptor coactivators are involved in receptor-mediated transcriptional activation of target genes in a hormone-sensitive manner, and the mechanism of their transactivation has been studied in recent years. The glucocorticoid receptor (GR) interacts with several coactivators, including steroid receptor coactivator-1 (SRC-1) family and CREB-binding(More)
The reliability and validity of a multidimensional 13-item index of competence, called the TMIG Index of Competence, were tested with data of 6776 elderly community residents. The index was designed to measure the higher-level competence which could not be adequately assessed by existing scales. A well-fitted second-order factor model was established. Three(More)
We screened mutations of two major tumor suppressor genes, p53 and PTEN, in 66 human brain tumors using a yeast-based functional assay and cDNA-based direct sequencing, respectively. The frequency of p53 mutations was 28.8% (19 of 66) and was higher in anaplastic astrocytoma (9 of 14, 64.3%,) than in glioblastoma multiforme (GBM; 7 of 27, 25.9%,),(More)
Projections of the subnuclei of the interpeduncular complex were studied by the retrograde horseradish peroxidase technique in the rat. The pars caudalis and pars dorsalis magnocellularis project to the septum, hippocampus and entorhinal cortex; a part of the pars medialis and the pars paramediana, to the dorsal thalamus; all subnuclei, to the midbrain(More)
Data from the longitudinal Koganei Study, Japan, have been used to predict long-term rate of change in three aspects of quality of life in community living elderly: physical, cognitive and social functioning. Two hundred and forty of the initially 69-71-year-old individuals (75% of the survivors) participated in all three examinations which took place in(More)
