PURPOSE In this study, biochemistry, molecular biology, immunohistochemistry, and electron microscopy techniques were used to examine whether versican, which is known to bind fibrillin-1, interacts with fibrillin-1 in the ciliary body and vitreous, and whether the versican in this complex binds to hyaluronan. METHODS The new polyclonal antibodies against(More)
PURPOSE To investigate the chemical toxicity of indocyanine green (ICG). METHODS Surface active and precipitating effects of ICG were quantitatively analyzed by determining bovine serum albumin dissolved or precipitated in the presence or absence of salt solutions. The effects of precipitation on serum and cytotoxicity were evaluated by measuring the(More)
Elevated concentrations of hyaluronan are often associated with human breast cancer malignancy. Here, we investigated the roles of hyaluronan in carcinogenesis and cancer progression using the mouse mammary tumor virus (MMTV)-Neu transgenic model of spontaneous breast cancer. Conditional transgenic mice that express murine hyaluronan synthase 2 (Has2) by(More)
Infliximab, a monoclonal antibody directed against human tumor necrosis factor-alpha (TNF-α), effectively treats anterior uveitis, which can accompany Behçet's disease. Here, we investigated the underlying mechanism of this action. We examined human, non-pigmented ciliary epithelial cells (HNPCECs), which make up the blood-aqueous barrier (BAB) in the uvea.(More)
BACKGROUND Cancers are supported by a distinct type of stroma, and versican is overexpressed in the stroma of malignant tumors, including breast cancer. Versican interacts with hyaluronan and fibrillin-1 at its amino terminus (G1) and carboxyl terminus (G3), respectively. Fibrillin-1 also associates with latent transforming growth factor-β binding protein(More)
We previously found that a covalent complex of SHAPs (serum-derived hyaluronan-associated proteins), the heavy chains of inter-alpha-trypsin inhibitor family molecules, with hyaluronan (HA) is accumulated in synovial fluid of patients with rheumatoid arthritis, and the complex is circulated in patient plasma at high concentrations. How the SHAP-HA complex(More)
MY-174 is an IgM class monoclonal antibody originally established against chick PG-M/versican. The antibody specifically stains the photoreceptor layer, where we recently reported an absence of PG-M/versican. In this study, we re-characterized the antibody and identified the molecule that reacts to MY-174 at the photoreceptor layer. Immunohistochemistry(More)
OBJECTIVES To investigate the long-term effect of infliximab on ocular and extraocular manifestations in patients with Behçet's disease. METHODS Seven patients with active Behçet's disease and treated with infliximab at Aichi Medical University Hospital for more than 18 months were included in the study. We evaluated visual acuity, the average number of(More)
Versican interacts with hyaluronan (HA) at its N-terminus and with fibrillin-1 at its C terminus. As versican in the dermis connects microfibrils to the HA-rich matrix for viscoelasticity, dermal diseases may involve destruction of these complexes. A recombinant versican protein, rVN, covering the HA binding region (HABR) of human versican and a polyclonal(More)
The evolution of vertebrates has included a number of important events: the development of cartilage, the immune system, and complicated craniofacial structures. Here, we examine domain shuffling as one of the mechanisms that contributes novel genetic material required for vertebrate evolution. We mapped domain-shuffling events during the evolution of(More)
