To predict the prognosis of neuroblastoma patients and choose a better therapeutic protocol, we developed a cDNA microarray carrying 5340 genes obtained from primary neuroblastomas and examined 136 tumor samples. We made a probabilistic output statistical classifier that provided a high accuracy in prognosis prediction (89% at 5 years) and a highly reliable(More)
The nematode Caenorhabditis elegans (C. elegans), a relatively simple organism in structure, is one of the most well-studied multicellular organisms. We developed a virtual C. elegans based on the actual organism to analyze motor control. We propose a dynamic body model, including muscles, controlled by a neural circuit model based on the actual nematode.(More)
Hepatoblastoma is one of the most common malignant liver tumors in young children. Recent evidences have suggested that the abnormalities in Wnt signaling pathway, as seen in frequent mutation of the beta-catenin gene, may play a role in the genesis of hepatoblastoma. However, the precise mechanism to cause the tumor has been elusive. To identify novel(More)
BACKGROUND In a rat model of orthotopic liver transplantation (OLT), recipient serum after OLT (post-OLT serum) has been reported to prevent allograft rejection. However, the molecular identities of immunosuppressive factors, which are in the early stage of post-OLT, remain elusive. This study was aimed to identify immunodominant suppressive factors present(More)
We previously demonstrated the immunosuppressive activity of anti-histone H1 autoreactive antibodies (Ab) transiently induced in serum of a rat tolerogenic orthotopic liver transplantation (OLT) model. In the present study, we investigated the effects of anti-histone H1 Ab on dendritic cells (DCs), T-cells, lymphokine-activated killer (LAK) cells, and human(More)
Approximately 20% of familial amyotrophic lateral sclerosis (FALS) arises from germ-line mutations in the superoxide dismutase-1 (SOD1) gene. However, the molecular mechanisms underlying the process have been elusive. Here, we show that a neuronal homologous to E6AP carboxyl terminus (HECT)-type ubiquitin-protein isopeptide ligase (NEDL1) physically binds(More)
Neuroblastoma (NBL), one of the most common childhood solid tumors, has a distinct nature in different prognostic subgroups: NBL in patients under 1 year of age usually regresses spontaneously, whereas that in patients over 1 year of age often grows aggressively and eventually kills the patient. To understand the molecular mechanism of biology and(More)
This paper focuses on the nematode C. elegans which has a relatively simple structure, and is one of the most analyzed organisms among multicellular ones. We aim to develop a mathematical model of this organism to analyze control mechanisms with respect to locomotion. First, a new motor control model of the C. elegans is proposed, which includes both of the(More)
A molecularly imprinted polymer was synthesized by using allyl phenyl disulfide as a template. The mixture of allyl phenyl disulfide, divinylbenzene, and 2,2'-azobis(isobutyronitrile) in chloroform was polymerized by UV irradiation for 24 h at 5 degrees C and further 3 h at 80 degrees C. The disulfide bonds of the resulting polymer were reductively cleaved(More)
Although numerous markers for bladder tumor (BT) have been investigated, a more effective, less expensive test is needed. To address this issue, we examined the urinary extracellular matrix (U-ECM) measurement in urine from patients with BT, and investigated the U-ECM measurement and its correlation with tumor grade and invasion. We also investigated the(More)
