Chronic stress produces structural changes and neuronal damage especially in the hippocampus. Because neurotrophic factors affect neuron survival, we questioned whether they might be relevant to the heightened vulnerability of hippocampal neurons following stress. To begin investigating this possibility, we examined the effects of immobilization stress (2(More)
We have isolated a cardiomyogenic cell line (CMG) from murine bone marrow stromal cells. Stromal cells were immortalized, treated with 5-azacytidine, and spontaneously beating cells were repeatedly screened. The cells showed a fibroblast-like morphology, but the morphology changed after 5-azacytidine treatment in approximately 30% of the cells; they(More)
BACKGROUND & AIMS : Ghrelin, an endogenous ligand for growth hormone secretagogue receptor, was recently identified in the rat stomach. We examined the effects of the gastric peptide ghrelin on energy balance in association with leptin and vagal nerve activity. METHODS : Food intake, oxygen consumption, gastric emptying, and hypothalamic neuropeptide Y(More)
The Arabidopsis pseudo-response regulator, APRR1, has a unique structural design containing a pseudo-receiver domain and a C-terminal CONSTANS motif. This protein was originally characterized as a presumed component of the His-to-Asp phosphorelay systems in Arabidopsis thaliana. Recently, it was reported that APRR1 is identical to the TOC1 gene product, a(More)
Coordinated growth and differentiation of external genitalia generates a proximodistally elongated structure suitable for copulation and efficient fertilization. The differentiation of external genitalia incorporates a unique process, i.e. the formation of the urethral plate and the urethral tube. Despite significant progress in molecular embryology, few(More)
A female mouse spontaneously exhibiting polyuria and glucosuria accompanied by rapid weight loss waa found in one of two sublines derived from the CTS mice. Eight mating pairs were made using its offspring and selection was performed for both spontaneous diabetes and reproductive ability. After six generations of the selective breeding the diabetic (nod)(More)
Ghrelin, an endogenous ligand of the growth hormone secretagogue receptor, was recently identified in the rat stomach. Previous studies have shown that ghrelin potently increases growth hormone release and food intake. We examined the effects of the gastric peptide ghrelin on anxiety-like behavior in association with the hypothalamic-pituitary-adrenal axis(More)
Hypothalamic-pituitary-adrenal (HPA) responses remain intact or increase after chronic or repeated stress despite robust levels of circulating glucocorticoids that would be expected to restrain the responsiveness of the axis. The purpose of this study was to determine whether chronic stress altered corticosteroid receptor messenger RNA (mRNA) levels at any(More)
The complete genomic sequence of the archaeon Thermoplasma volcanium, possessing optimum growth temperature (OGT) of 60 degrees C, is reported. By systematically comparing this genomic sequence with the other known genomic sequences of archaea, all possessing higher OGT, a number of strong correlations have been identified between characteristics of genomic(More)
A recessive mouse mutation, mesenchymal dysplasia (mes), which arose spontaneously on Chromosome 13, causes excess skin, increased body weight, and mild preaxial polydactyly. Fine gene mapping in this study indicated that mes is tightly linked to patched (ptc) that encodes a transmembrane receptor protein for Shh. Molecular characterization of the ptc gene(More)
