Carbonic anhydrase (CA) IX is a transmembrane isozyme of CAs that catalyzes reversible hydration of CO(2). While it is known that CA IX is distributed in human embryonic chondrocytes, its role in chondrocyte differentiation has not been reported. In the present study, we found that Car9 mRNA and CA IX were expressed in proliferating but not hypertrophic chondrocytes. Next, we examined the role ...
Factor VIII (fVIII) functions as a cofactor of factor IXa in the intrinsic pathway of blood coagulation. Its absence or abnormality causes the bleeding disorder hemophilia A. About 23% of hemophiliacs who receive therapeutic fVIII infusions develop antibodies that inhibit its activity. We previously showed by inhibitor neutralization assays that the fVIII A2 and C2 domain polypeptides contain c...
Residue K5 in factor IX gamma-carboxyglutamic acid (Gla) domain participates in binding endothelial cells/collagen IV. We injected recombinant factor IX containing mutations at residue 5 (K5A, K5R) into factor IX-deficient mice and compared their behavior with that of wild-type factor IX. The plasma concentration of factor IX that binds to endothelial cells/collagen IV (recombinant wild type an...
Factor IX has been expressed to high levels within a recombinant host cell and the biologically active fraction subsequently purified to homogeneity for characterization. The coding sequence for Factor IX was inserted into a mammalian cell expression vector and transfected into dihydrofolate reductase-deficient Chinese hamster ovary cells. The integrated DNA was amplified to a high copy number ...
Coagulation factor IX is a vitamin K-dependent glycoprotein that circulates in blood as a precursor of a serine protease. Incubation of human factor IX with human alpha-thrombin resulted in a time and enzyme concentration-dependent cleavage of factor IX yielding a molecule composed of a heavy chain (mol wt 50,000) and a doublet light chain (mol wt 10,000). The proteolysis of factor IX by thromb...
The blood coagulation factor thrombin that leaks from ruptured vessels initiates brain tissue damage after intracerebral hemorrhage. We have recently shown that mitogen-activated protein kinases (MAPKs) activated by thrombin exacerbate hemorrhagic brain injury via supporting survival of neuropathic microglia. Here, we investigated whether induction of heme oxygenase (HO)-1 is involved in these ...
شوری خاک یکی از عوامل مهم محیطی است که منجر به کاهش عملکرد گیاهان زراعی می شود. شناخت مکانیسم های مقاومت گیاهان در برابر تنش ها می تواند به شناسایی ژن های مقاومت و کاربرد آن ها در اصلاح گیاهان و افزایش محدوده کشت گیاهان منجر شود. روش آنالیز expressed sequence tag (est) و داده های ریزآرایه راهی سریع و منطقی برای شناسایی ژن های نامزد جدید برای مقاومت به تنش ها می باشد. در این تحقیق تعداد 2 کتابخا...
The metabolic detoxication/bioactivation pathways, the levels and activity of enzymes, and endogenous cofactors mediating these reactions in crops have been well document‐ ed; however, much less evidence has been accumulated in weed species. The herbicide metabolism as a selectivity factor is summarized with special attention to acetyl-CoA car‐ boxylases (ACCase)-inhibiting aryloxyphenoxypropio...
only DESCRIPTION Coagulation Factor IX (Human), Mononine, is a sterile, stable, lyophilized concentrate of Factor IX prepared from pooled human plasma and is intended for use in therapy of Factor IX deficiency, known as Hemophilia B or Christmas disease. Mononine is purified of extraneous plasma-derived proteins, including Factors II, VII and X, by use of immunoaffinity chromatography. A murine...
