The natriuretic peptide (NP) family consists of seven paralogs [atrial NP (ANP), brain NP (BNP), ventricular NP (VNP), and C-type NP 1-4 (CNP1-4)] in teleosts, but relative biological activity of the seven NPs has not been comprehensively examined using homologous peptides. In this study, we newly identified CNP3 and CNP4 in eels to use homologous peptides, but the CNP2 gene may have been silen...
The RNA genome of influenza virus is encapsidated by the virus nucleoprotein (NP) to form ribonucleoprotein (RNP) structures of defined morphology. These structures result from the ability of NP to oligomerise and to bind single-strand RNA. To characterise NP oligomerization, we developed a binding assay using immobilised NP fusion proteins and in vitro translated NP. This system was used to es...
BACKGROUND It has been reported that oxidation product of cholesterol, 7-ketocholesterol, increases in plasma of patients with NP-C. Previously, we established a rapid test to determine the plasma 7-ketocholesterol level and found it elevated significantly in patients with acid sphingomyelinase deficient NPD and NP-C disease. METHODS Individuals randomly referred to our outpatient clinics in ...
Knowledge of factors regulating the turnover, repair, and degeneration of the intervertebral disc (IVD) is lacking. Although type II collagen (CII) fragments accumulate in the degenerative IVD, little is known of how they affect the degenerative process. A better understanding of the cellular interactions with fragments of matrix molecules are a key factor in promoting therapies for degenerativ...
The complexity, approximation and algorithmic issues of several clustering problems are studied. These non-traditional clustering problems arise from recent studies in microarray data analysis. We prove the following results. (1) Two variants of the Order-Preserving Submatrix problem are NP-hard. There are polynomial-time algorithms for the Order-Preserving Submatrix problem when the condition ...
As large-scale techniques for studying and measuring gene expressions have been developed, automatically inferring gene interaction networks from expression data has emerged as a popular technique to advance our understanding of cellular systems. Accurate prediction of gene interactions, especially in multicellular organisms such as Drosophila or humans, requires temporal and spatial analysis o...
Optimal gene therapy for tumors must deliver DNA to tumor cells with high efficiency and minimal toxicity. It has been reported that in non-viral gene delivery, the hydroxyethyl group at the amino terminal in cationic lipid was important for high transfection efficiency. Therefore, in this study, we developed new cationic nanoparticles (NP-OH) composed of cholesteryl-3beta-carboxyamidoethylene-...
1. Niemann-Pick disease type C (NP-C) is an autosomal recessive lipidosis with protean clinical manifestations, distinguished biochemically by a unique error in cellular trafficking of exogenous cholesterol that is associated with lysosomal accumulation of unesterified cholesterol. A majority of patients with this phenotype are linked genetically to chromosome 18, the locus of Niemann-Pick dise...
