The 90-kDa stress protein, HSP90, is a major cytosolic protein ubiquitously distributed in all species. Using two substrate proteins, dihydrofolate reductase (DHFR) and firefly luciferase, we demonstrate here that HSP90 newly acquires a chaperone activity when incubated at temperatures higher than 46 degrees C, which is coupled with self-oligomerization of(More)
Two lines of mice selected for reproductive longevity were compared with one unselected control line to examine longevity and lifetime performance such as number of parturitions during lifetime. Mice were pair mated at about 8 weeks of age and cohabited throughout life. Litter size was reduced to eight at birth in selected line 121 and unselected control(More)
The Escherichia coli GroEL subunit consists of three domains with distinct functional roles. To understand the role of each of the three domains, the effects of mutating a single residue in each domain (Y203C at the apical, T89W at the equatorial, and C138W at the intermediate domain) were studied in detail, using three different enzymes (enolase, lactate(More)
We present an adrenal Ewing's sarcoma family of tumor (ESFT) arising in an 11-year-old Japanese boy. Although intensive chemoradiotherapy and radical surgery were performed, the patient died of obstinate disease 1 year and 3 months after the initial presentation. The primary site (adrenal gland) with radiologic findings (with foci of calcification), high(More)
PURPOSE Intensive chemoradiotherapy followed by peripheral blood stem cell transplantation has been introduced to treat children with advanced neuroblastoma (NBL). Detection of NBL cells in peripheral blood (PB) is important to prevent reinfusion of NBL cells. Several immunologic methods have been proposed for detecting NBL cells in hematologic samples. The(More)
P53 protein expression in malignant cells of five patients with Burkitt lymphoma (BL) and from two patients with B-cell acute lymphoblastic leukemia (B-ALL) was examined with anti p53 protein monoclonal antibodies PAb1801, PAb240 and p53-D07 using an immunocytochemical technique. Four of the seven patients were positive. The distribution of positive(More)
Correlated responses to selection for increased growth rate were compared in two mouse populations (M16 and H6) of distinct genetic origin. Traits studied were body composition, feed intake, constituent gains and energetic efficiency. When compared with their respective controls (ICR and C2) at 6 and 9 weeks of age, body weight increased more in M16 (57%and(More)
