The modulation of complement functional efficiency by serum histidine-rich glycoprotein (HRG) was investigated. Addition of exogenous HRG to prewarmed diluted serum, followed immediately by sensitized sheep erythrocytes (EA), resulted in enhanced hemolysis. However, when HRG was incubated with diluted serum for 10 minutes at 37 degrees C, inhibition of hemolysis occurred. The biphasic modulatio...
Histidine-rich glycoprotein (HRG) is implicated in tumor growth and metastasis by regulation of angiogenesis and inflammation. HRG is produced by hepatocytes and carried to tissues via the circulation. We hypothesized that HRG's tissue distribution and turnover may be mediated by inflammatory cells. Biodistribution parameters were analyzed by injection of radiolabeled, bioactive HRG in the circ...
Graphene based sulfonated polyvinyl alcohol (PVA) hydrogel was synthesized and its performance as nanocomposite gel polymer electrolyte investigated for application in quasi solid-state flexible supercapacitors. Hydrothermally reduced graphene (HRG) through hydrothermal reduction of oxide (GO). Sulfonated PVA (SPVA) with predetermined quantities HRG to obtain electrolytes coded SPVA-HRG-x (x = ...
BACKGROUND The heparin-binding plasma protein histidine-rich glycoprotein (HRG; alternatively, HRGP/HPRG) can suppress tumor angiogenesis and growth in vitro and in vivo. Mice lacking the HRG gene are viable and fertile, but have an enhanced coagulation resulting in decreased bleeding times. In addition, the angiogenic switch is significantly enhanced in HRG-deficient mice. METHODOLOGY/PRINCI...
Histidine-rich glycoprotein (HRG) circulates in plasma at a concentration of 2 M and binds plasminogen, fibrinogen, and thrombospondin. Despite these interactions, the physiologic role of HRG is unknown. Previous studies have shown that mice and humans deficient in HRG have shortened plasma clotting times. To better understand this phenomenon, we examined the effect of HRG on clotting tests. HR...

Title of Document: DELINEATING THE ROLES OF C. ELEGANS HEME RESPONSIVE GENES HRG-2 AND HRG-3 IN HEME HOMEOSTASIS Caiyong Chen, Doctor of Philosophy, 2009 Directed By: Associate Professor Dr. Iqbal Hamza, Department of Animal and Avian sciences Heme is an essential cofactor for diverse biological processes such as oxygen transport, xenobiotic detoxification, and circadian clock control. Since fr...
Streptococcuspyogenes isasignificantbacterial pathogen in humans. In this study, histidine-rich glycoprotein (HRG), an abundant plasma protein, was found to kill S pyogenes. Furthermore, S pyogenes grew more efficiently in HRG-deficient plasma, and clots formed in this plasma were significantly less effective at bacterial entrapment and killing. HRG-deficient mice were strikingly more susceptib...
PURPOSE We sought to gain insight into the mechanisms of heregulin-beta1 (HRG) action on breast epithelial cells by identifying and characterizing HRG-regulated proteins. EXPERIMENTAL DESIGN Differential display mRNA screening of human breast cancer cells grown in the presence or absence of HRG was used to identify HRG-regulated genes. Biochemical and functional studies were undertaken to exa...
