PSD-95 is a component of postsynaptic densities in central synapses. It contains three PDZ domains that localize N-methyl-D-aspartate receptor subunit 2 (NMDA2 receptor) and K+ channels to synapses. In mouse forebrain, PSD-95 bound to the cytoplasmic COOH-termini of neuroligins, which are neuronal cell adhesion molecules that interact with beta-neurexins(More)
At synaptic junctions, pre- and postsynaptic membranes are connected by cell adhesion and have distinct structures for specialized functions. The presynaptic membranes have a machinery for fast neurotransmitter release, and the postsynaptic membranes have clusters of neurotransmitter receptors. The molecular mechanism of the assembly of synaptic junctions(More)
PSD-95/SAP90 is a member of membrane-associated guanylate kinases localized at postsynaptic density (PSD) in neuronal cells. Membrane-associated guanylate kinases are a family of signaling molecules expressed at various submembrane domains which have the PDZ (DHR) domains, the SH3 domain, and the guanylate kinase domain. PSD-95/SAP90 interacts with(More)
The potential link between depression and cancer is an important unsolved question. To clarify this, we compared a cancer-related oxidative DNA damage, 8-hydroxydeoxyguanosine (8-OH-dG), in peripheral leukocytes between 30 patients with depression and 60 age- and gender-matched healthy controls, and examined the 8-OH-dG-related factors. The degree of(More)
We have recently isolated a rat homologue of the Caenorrhabditis elegans lin-10 product. Although rat lin-10 is expressed in the cytosol and membrane fractions of various tissues, it is distributed only in the membrane fraction in brain where it is enriched in the synaptic plasma membrane and postsynaptic density fractions. We have isolated here a rat(More)
BACKGROUND The present study investigates whether the formation of 8-hydroxydeoxyguanosine (8-OH-dG), a known oxidative DNA damage relevant to carcinogenicity, can be associated with psychological factors, in order to clarify the possible stress-cancer linkage from a genetic viewpoint. METHODS We performed a cross-sectional study in which we examined the(More)
This study investigated whether the formation of 8-hydroxydeoxyguanosine (8-OH-dG), a known oxidative DNA modification relevant to carcinogenicity, can be classically conditioned to a novel taste in order to clarify the possible role of the central nervous system (CNS) or psychological stress on cancer initiation via a classical conditioning mechanism. Male(More)
PSD-95/SAP90 is a synaptic membrane-associated guanylate kinase with three PDZ, one SH3, and one guanylate kinase (GK) domain. PSD-95/SAP90 binds various proteins through the PDZ domains and organizes synaptic junctions. PSD-95/SAP90 also interacts with the postsynaptic density (PSD) fraction-enriched protein, named SAPAP (also called GKAP and DAP), through(More)
The development of actuators based on materials that reversibly change shape and/or size in response to external stimuli has attracted interest for some time. A particularly intriguing possibility is offered by light-responsive materials, which allow remote operation without the need for direct contact to the actuator. The photo-response of these materials(More)
Photochromism is defined as a reversible transformation of a chemical species between two isomers upon photoirradiation. Although vast numbers of photochromic molecules have been so far reported, photochromic molecules which exhibit thermally irreversible photochromic reactivity are limited to a few examples. The thermal irreversibility is an indispensable(More)
