Isolation of a natural inhibitor of human malignant glial cell invasion: inter alpha-trypsin inhibitor heavy chain 2.
Malignant central nervous system (CNS) tumors, such as glioblastoma multiforme, invade the brain and disrupt normal tissue architecture, making complete surgical removal virtually impossible. Here, we have developed and optimized a purification strategy to isolate and identify natural inhibitors of glioma cell invasion in a three-dimensional collagen type I matrix. Inter alpha-trypsin inhibitor...
متن کاملTwo RFLPs in human inter-alpha-trypsin inhibitor heavy chain gene ITIH2 on chromosome 10.
SOURCE AND DESCRIPTION OF CLONE : The 0.8 kb Eco RI / Bam HI fragment of lambda HuHITI-9 (1) used as a probe codes for human heavy chain H2 of the inter-alpha-trypsin inhibitor (2). POLYMORPHISMS : Kpn 1 (GGTAC/C) identifies one invariant band at 8.5 kb and a diaJlelic polymorphism with DNA fragments at 26.0 kb or 20.0 kb. Msp I (C/CGG) identifies three invariant bands at 2.35 kb, 2.1 kb and 1....
متن کاملSite-Specific Glycan Microheterogeneity of Inter-Alpha-Trypsin Inhibitor Heavy Chain H4
Inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4) is a 120 kDa acute-phase glycoprotein produced primarily in the liver, secreted into the blood, and identified in serum. ITIH4 is involved in liver development and stabilization of the extracellular matrix (ECM), and its expression is altered in liver disease. In this study, we aimed to characterize glycosylation of recombinant and serum-deri...
متن کاملIsolation and characterization of the promoter and partial enhancer region of the porcine inter-alpha-trypsin inhibitor heavy chain 4 gene.
A porcine genomic library was screened for clones containing the promoter of the major acute-phase protein in pigs, inter-alpha-trypsin heavy chain 4 (ITIH4). Following isolation of the promoter, a functional analysis was performed with Hep3B cells. The promoter was induced by interleukin-6 (IL-6) but not by IL-1beta. However, IL-1beta was shown to inhibit the IL-6-induced activation of the por...
متن کاملHuman alpha-crystallin. I. The isolation and characterization of newly synthesized alpha-crystallin.
Studies of the incorporation of 14C amino acids into human lens proteins demonstrate that an alpha-crystallin fraction takes up more than six times as much radioactivity as any other lens protein. Based on analyses with a calibrated Bio-Gel A-1.5 m column, a molecular weight of 4.9 x 10(5) +/- 5 per cent was obtained for this protein while sedimentation equilibrium analyses indicated a weight a...
