Matrix metalloproteinases (MMPs) are essential for proper extracellular matrix remodeling. We previously found that a membrane-anchored glycoprotein, RECK, negatively regulates MMP-9 and inhibits tumor invasion and metastasis. Here we show that RECK regulates two other MMPs, MMP-2 and MT1-MMP, known to be involved in cancer progression, that mice lacking a(More)
Triple helix formation of procollagen after the assembly of three alpha-chains at the C-propeptide is a prerequisite for refined structures such as fibers and meshworks. Hsp47 is an ER-resident stress inducible glycoprotein that specifically and transiently binds to newly synthesized procollagens. However, the real function of Hsp47 in collagen biosynthesis(More)
— This report presents the results of KINECT applications used in physical rehabilitation tests. Aoyama Gakuin and Kitasato universities collaborated on this project, which is supported by SCOPE. The applications, following standard tests, are for the timed " Up & Go Test " , the timed " 10-Meter Walk Test " and for a Joint " Range of Motion " Measurement "(More)
Progressive aggregation of α-synuclein (αS) from pale bodies (PBs) and extension from Lewy neurites (LNs) are candidate mechanisms for Lewy body (LB) formation. To identify how aggregation of αS is related to its extension along neurites, 60-µm-thick brainstem sections of Parkinson disease (PD) patients were prepared for three-dimensional (3D)(More)
The membrane-anchored metalloproteinase-regulator RECK has been characterized as a tumor suppressor. Here we report that mice with reduced Reck-expression show limb abnormalities including right-dominant, forelimb-specific defects in postaxial skeletal elements. The forelimb buds of low-Reck mutants have an altered dorsal ectoderm with reduced Wnt7a and(More)
Nerve apposition on nicotinic acetylcholine receptor clusters and invagination of the post-synaptic membrane (i.e. secondary fold formation) occur by embryonic day 18.5 at the neuromuscular junctions (NMJs) in mouse skeletal muscles. Finding the molecules expressed at the NMJ at this stage of development may help elucidating how the strong linkage between a(More)
In polarized epithelial cells, agonists trigger Ca2+ waves and oscillations. These patterns may be caused by the compartmentalization of inositol 1,4,5-trisphosphate (IP3)-sensitive Ca2+ pools into specific regions. We have investigated the relationship between the distribution of IP3 receptors (IP3Rs) and the spatiotemporal pattern of Ca2+ signaling in the(More)
Lipidosin is an 80-kDa protein with long-chain acyl-CoA synthetase activity expressed in the brain, adrenal gland, testis, and ovary, which are selectively damaged in X-linked adrenoleukodystrophy (X-ALD). Western blot analysis of the cerebrum and cerebellum revealed a gradual increase in the expression of lipidosin postnatally. Light microscopic(More)
