To elucidate the induction mechanism of HSP70 by geranylgeranylacetone (GGA), we investigated GGA specific binding proteins using a GGA-affinity column. Alteration of chaperone activity of HSP70 and binding affinity of HSP70 to heat shock factor-1 (HSF-1) was evaluated in the presence or absence of GGA. The binding domain of HSP70 to GGA was also analyzed.(More)
The 90-kDa heat shock protein (HSP90) is a molecular chaperone that assists in the folding and assembly of proteins in the cytosol. We previously demonstrated that the antineoplastic reagent, cisplatin, inhibits the aggregation prevention activity of mammalian HSP90. We now show that cisplatin binds both the amino terminal and carboxyl terminal domains of(More)
We purified from porcine pancreas a hypocalcemic peptide clearly distinguishable from other pancreatic osteotropic factors such as amylin, calcitonin, and glucagon. Porcine pancreas was processed by acetone extraction, anion exchange chromatography, isoelectric focusing, and reverse-phase high performance liquid chromatography. Fractions were assayed for(More)
Porcine pancreatic extracts (PXs) have previously been shown to decrease blood ionized calcium in BALB/c mice (T. Yoneda, Y. Takaoka, and G. R. Mundy. FEBS Lett., 278: 171-174, 1991). In the present study, we show that the PX is effective in preventing progression of hypercalcemia and decreasing osteoclastic bone resorption associated with a human squamous(More)
Patients with acute pancreatitis commonly manifest hypocalcemia for reasons which are unknown. We found that porcine pancreas extracts (PX) significantly decreased blood-ionized calcium in Balb/c mice. Partially-purified PX with a molecular mass of approximately 27 kDa decreased blood-ionized calcium in the mice. Partially-purified PX suppressed not only(More)
The cytoarchitecture of dorsal cochlear nucleus (DCN), characterized by a distinct laminar structure similar to the cerebellar cortex of the normal mouse, is known to be disrupted in the Reelin-deficient mouse, reeler. Here, we have reexamined both the cytoarchitecture and myeloarchitecture of this nucleus and described expression pattern of Reelin protein(More)
AIM To identify in-house assessment criteria to predict outcomes of driving tests in patients with stroke who wish to resume driving. MATERIAL AND METHODS A total of 181 patients with stroke who attended Fukui General Hospital (as outpatients or inpatients) between 2003 and 2015 and who had no obvious motor impairment were included in the study.
