cis-Aconitic acid decarboxylase (CAD) was assumed to be a key enzyme in the production of itaconic acid by comparing the activity of CAD from Aspergillus terreus TN484-M1 with that of CAD from the low-itaconate yielding strain Aspergillus terreus CM85J. The constitutive CAD was purified to homogeneity from A. terreus TN484-M1 by ammonium sulfate(More)
PURPOSE The aim of this study was to determine whether genetic polymorphism of complement factor H (CFH) is associated with age-related macular degeneration (AMD) in the Japanese population. METHODS Genomic DNA was examined in a cohort of 67 Japanese patients with AMD and 107 controls. TT/TC/CC genotypes on exon 9 were screened for sequence alternation by(More)
Age-related macular degeneration (AMD) is one of the leading causes of blindness among older adults in developed countries and also in Japan. Previous research suggests that AMD is etiologically a complex disease, caused by multiple genes and environmental factors. Association studies have identified that a complement factor H gene (CFH) variant is a major(More)
Telomerase activity was measured in biopsy specimens as well as surgically resected tissues of 39 oral squamous cell carcinomas (SCCs), 22 oral leukoplakias, 13 normal oral mucosas, 12 malignant salivary gland tumors, 10 benign salivary tumors and five normal salivary gland tissues adjacent to tumors using a polymerase chain reaction (PCR)-based telomerase(More)
The incidence of glaucoma increases with age, as does age-related macular degeneration (AMD), with the reported incidence of glaucoma among AMD subjects being 5.4 %. Optical coherence tomography (OCT) can detect glaucomatous changes in the inner retina with high sensitivity. The purpose of this study was to compare ganglion cell complex (GCC) parameters and(More)
PURPOSE Various protein contents such as enzymes, growth factors, and structural components are responsible for biological activities in organs. We have created a map of vitreous proteins and developed a proteome analysis of human vitreous samples to understand the underlying molecular mechanism and to provide clues to new therapeutic approaches in eyes(More)
We investigated the differential protein expression patterns of retinal pigment epithelial (RPE) cells exposed to increased glucose concentrations. Cultured human RPE cells (ARPE-19) were exposed for 4 days with normal blood glucose concentration (5.5 mM D-glucose), followed by exposure to either normal (5.5 mM) or high (33 mM) concentrations of D-glucose(More)
Development and homeostasis of multicellular organisms require interactions between neighbouring cells. We recently established an in vitro model of cell-cell interaction based on a collagen vitrigel membrane. We have now examined the role of neural cells in retinal homeostasis by coculture of human retinal pigment epithelial (RPE) cells and neural cells on(More)
Semaphorins not only function in axon guidance during development but also contribute to various other biological processes. We have now examined the expression of semaphorin 3A (Sema3A) and its receptor components neuropilin 1 (Npn1) and plexin A (PlxA) during development of the mouse retina. Immunohistofluorescence analysis revealed that the expression(More)
