The growth factor progranulin (PGRN) has been implicated in embryonic development, tissue repair, tumorigenesis, and inflammation, but its receptors remain unidentified. We report that PGRN bound directly to tumor necrosis factor receptors (TNFRs) and disturbed the TNFα-TNFR interaction. PGRN-deficient mice were susceptible to collagen-induced arthritis,(More)
Immune homeostasis is essential for the normal functioning of the immune system, and its breakdown leads to fatal inflammatory diseases. We report here the identification of a member of the tumor necrosis factor-alpha-induced protein-8 (TNFAIP8) family, designated TIPE2, that is required for maintaining immune homeostasis. TIPE2 is preferentially expressed(More)
The purpose of this study was to evaluate the prognostic value of metabolic tumor volume (MTV) and metabolic index (MI) from fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in patients with nasopharyngeal carcinoma (NPC). From October 2002 to July 2004, 41 patients with NPC who underwent 18F-FDG PET-CT scan(More)
OBJECTIVE To determine 1) whether a protein interaction network exists between granulin-epithelin precursor (GEP), ADAMTS-7/ADAMTS-12, and cartilage oligomeric matrix protein (COMP); 2) whether GEP interferes with the interactions between ADAMTS-7/ADAMTS-12 metalloproteinases and COMP substrate, including the cleavage of COMP; 3) whether GEP affects tumor(More)
PURPOSE Glaucoma is the second leading cause of blindness. The ultimate cause of vision loss in glaucoma is thought to be retinal ganglion cell (RGC) death. Neuroprotection of RGC is therefore an important goal of glaucoma therapy. Several lines of evidence suggest that pigment epithelium derived factor (PEDF) is a potent anti-angiogenic, neuroprotective,(More)
Brain-derived neurotrophic factor (BDNF) plays an essential regulatory role in the survival and differentiation of various neural cell types during brain development and after injury. In this study, we used neural stem cells (NSCs) genetically modified to encode BDNF gene (BDNF/NSCs) and naive NSCs transplantation and found that BDNF/NSCs significantly(More)
Glaucoma is a common cause of blindness affecting at least 66 million people worldwide. Pigmentary glaucoma is one of the most common forms of secondary glaucoma, and its pathogenesis remains unclear. Interleukin-18 (IL-18) is an important regulator of innate and acquired immune responses and plays an important role in inflammatory/autoimmunity diseases.(More)
MicroRNAs (miRNA) are short non-coding RNA molecules that regulate a variety of biological processes. The role of miRNAs in BMP2-mediated biological processes is of considerable interest. A comparative miRNA array led to the isolation of several BMP2-responsive miRNAs. Among them, miR-199a(*) is of particular interest, because it was reported to be(More)
ADAMTS-7, a metalloproteinase that belongs to ADAMTS family, is important for the degradation of cartilage extracellular matrix proteins in arthritis. Herein we report that ADAMTS-7 is upregulated during chondrocyte differentiation and demonstrates the temporal and spatial expression pattern during skeletal development. ADAMTS-7 potently inhibits(More)
Neurological soft signs (NSS) - i.e. discrete deficits of sensory and motor function - are frequently found in schizophrenia and vary with psychopathological symptoms in the course of the disorder. Hence, persistence of NSS herald chronicity in first episode schizophrenia. To investigate the cerebral correlates of persisting NSS over time, 20 patients with(More)
