Recent evidence suggests that the basement membrane not only separates basal cells from Bowman's layer, but also has a crucial role in the proliferation, differentiation and migration of corneal epithelial cells. The basement membrane is composed of a mixture of matrix components including collagens, laminins and heparan sulfate proteoglycans. In these(More)
A comprehensive survey of Japanese patients with adult Still's disease was made by questionnaire which was sent to major institutions with rheumatology units in Japan. Of 146 cases from 32 institutions, 90 were judged to be definitely diagnosed as adult Still's disease. The major clinical features in these 90 patients consisted of high fever,(More)
Laminin 5 (LN5), a heterotrimer of laminin alpha 3. beta 3. and gamma 2 chains. is a laminin isoform which strongly promotes adhesion. migration. and scattering of cells through binding to integrins alpha 3 beta 1, alpha 6 beta 1 and alpha 6 beta 4. To get an insight into the physiological functions of LN5, we prepared a mouse monoclonal antibody to human(More)
We have demonstrated that ischemic neuronal death (apoptosis) of rat CA1 region of the hippocampus was prevented by infusing pituitary adenylate cyclase-activating polypeptide (PACAP) either intracerebroventricularly or intravenously. We have also demonstrated that the activity of mitogen-activated protein (MAP) kinase family members, including ERK(More)
This 8-year-old boy presented with a rare case of epidural hematoma of the clivus and atlantoaxial dislocation caused by a hyperflexion injury sustained in a traffic accident. Magnetic resonance (MR) imaging demonstrated an epidural hematoma in the posterior fossa that compressed the pons and medulla. On admission, the patient was confused and had bilateral(More)
Laminin (LN)-5, a heterotrimer of alpha3, beta3, and gamma2 chains, has been suggested to be involved in tumor cell invasion. The present immunohistochemical study investigated the distribution of the LN gamma2 chain in 48 different human gastric adenocarcinomas. The immunohistochemical analysis showed two distinct patterns of LN gamma2 chain expression:(More)
Defining apoptosis-regulatory cascades of the epithelium is important for understanding carcinogenesis, since cancer cells are considered to arise as a result of the collapse of the cascades. We previously reported that a novel gene GASDERMIN (GSDM) is expressed in the stomach but suppressed in gastric cancer cell lines. Furthermore, in this study, we(More)
We have demonstrated that the ischemia-induced apoptosis of neurons in the CA1 region of the rat hippocampus was prevented by either intracerebroventricular or intravenous infusion of pituitary adenylate cyclase-activating polypeptide (PACAP). However, the molecular mechanisms underlying the anti-apoptotic effect of PACAP remain to be determined. Within 3-6(More)
Three cDNA clones coding for rat platelet phospholipase A2 and a homologous protein were isolated from a rat megakaryocyte cDNA library and sequenced. One (prPLA2-1) carries a 708 nucleotide long insert. The others (prPLA2-2 and -3) differ from clone 1 in three nucleotides and have a 748 nucleotide long insert. All contain a single open reading frame which(More)
Transient global ischemia caused by 5 min of cardiac arrest induced delayed neuronal cell death (apoptosis) in the CA1 region of the rat hippocampus. To characterize the molecular mechanisms that regulate apoptosis in vivo, the contributions to cell death of mitogen-activated protein kinase family members were examined in the hippocampal region after brain(More)
