Mouse Gestation Length Is Genetically Determined
BACKGROUND Preterm birth is an enormous public health problem, affecting over 12% of live births and costing over $26 billion in the United States alone. The causes are complex, but twin studies support the role of genetics in determining gestation length. Despite widespread use of the mouse in studies of the genetics of preterm birth, there have been few studies that actually address the preci...
متن کاملEXPRESSION OF HUMAN PROTEINASE 3 IN CHINESE HAMSTER OVARY CELLS (CHO-CELLS)
Proteinase 3(PR3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (ANCA) found in Wegener's granulomatosis (WG). We developed a stable expression system for conformationally intact recombinant PR3 (rPR3) in Chinese hamster ovary cells (CHO-cells). The part of PR3 cDNA that encoded the active form of PR3 was s...
متن کاملConstitutive membrane expression of proteinase 3 (PR3) and neutrophil activation by anti-PR3 antibodies.
Antineutrophil cytoplasm autoantibodies with specificity for proteinase 3 (PR3) are thought to play a major role in the pathogenesis of Wegener's granulomatosis (WG), presumably by their potential to activate neutrophils. In patients with WG, high expression of PR3 on the surface of nonprimed neutrophils is associated with an increased incidence and rate of relapse. In this study, we analyzed t...
متن کاملLeucocyte membrane expression of proteinase 3 correlates with disease activity in patients with Wegener's granulomatosis.
Wegener's granulomatosis (WG) is an inflammatory disorder characterized by granulomatous inflammation and vasculitis, and is strongly associated with antineutrophil cytoplasmic antibodies (ANCA). ANCA in patients with WG are directed against proteinase 3 (Pr3) in most of the cases. In vitro, upon neutrophil priming, ANCA antigens are expressed on the cell surface, thereby becoming available for...
متن کاملTissue specificity of geminivirus infection is genetically determined.
The types of cells and tissues infected by a virus define its tissue tropism. Determinants of tissue tropism in animal-infecting viruses have been extensively investigated, but little is known about plant viruses in this regard. Some geminiviruses in the genus Begomovirus exhibit phloem limitation and are restricted to cells of the vascular system, whereas others can invade mesophyll tissue. To...
