Clinical Features of Patients with Anti-Neutrophil Cytoplasmic Autoantibodies Targeting Native Myeloperoxidase Antigen
Background/Purpose: ANCA is a useful diagnostic marker in systemic vasculitic disorders with small-vessel involvement, but depending on the particular test used the myeloperoxidase (MPO)-ANCA results…Abstract Number: 1497 • 2012 ACR/ARHP Annual Meeting
Activation of Sirt1 Attenuates Bleomycin Induced Scleroderma Through Inhibiting Mammalian Target of Rapamycin Activation
Background/Purpose: Scleroderma is an autoimmune disease, characterized by progressive fibrosis of skin and internal organs. Inflammation is one of the main manifestations of scleroderma, especially…Abstract Number: 1498 • 2012 ACR/ARHP Annual Meeting
Wisp-1 Neutralization Reduces Gvhd-Induced Skin Fibrosis by Altering TSLP-OX40L Axis-Dependent Th2 Responses
Background/Purpose: There is accumulating evidence for a role of Wnt-signaling pathway activation in connective tissue disorders, including dermal and lung fibrosis. In particular, expression of…Abstract Number: 1499 • 2012 ACR/ARHP Annual Meeting
The Soluble Guanylate Cyclase Mediates Its Anti-Fibrotic Effects by Inhibiting TGF-β Signaling
Background/Purpose: We have recently demonstrated that stimulation of the soluble guanylate cyclase (sGC) has potent anti-fibrotic activity in different models of fibrosis. sGC stimulation increases…Abstract Number: 1500 • 2012 ACR/ARHP Annual Meeting
Activation of Pregnane X Receptor Induces Regression of Experimental Dermal Fibrosis
Background/Purpose: Pregnane-X-receptor (PXR) belongs to a superfamily of nuclear receptors that function as ligand-activated transcriptional factors. Although endogenous ligands have not yet been identified, PXR…Abstract Number: 1501 • 2012 ACR/ARHP Annual Meeting
Increased Periostin Levels in Patients with Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) results in significant morbidity and mortality due to organ fibrosis characterized by increased deposition of extracellular matrix (ECM). Periostin is one…Abstract Number: 1502 • 2012 ACR/ARHP Annual Meeting
Hedgehog Signaling in Murine Chronic Sclerodermatous Graft-Versus-Host Disease
Background/Purpose: Sclerodermatous chronic graft-versus-host disease (cGvHD) is a prognosis limiting complication of allogeneic bone marrow transplantation. cGvHD can manifest on virtually every organ system. However,…Abstract Number: 1503 • 2012 ACR/ARHP Annual Meeting
Effect of Thiol Antioxidants On the Profibrotic Phenotype of Scleroderma Dermal Fibroblasts
Background/Purpose: Systemic sclerosis (Scleroderma, SSc) is a connective tissue disease characterized by vasculopathy and fibrosis of the skin and organs. Increase in superoxide production and…Abstract Number: 1504 • 2012 ACR/ARHP Annual Meeting
A Possible Contribution of Visfatin to the Resolution of Skin Sclerosis in Patients with Diffuse Cutaneous Systemic Sclerosis Via a Direct Anti-Fibrotic Effect On Dermal Fibroblasts and Th1 Polarization of the Immune Response
Background/Purpose: Our latest studies have demonstrated that adipocytokines, including adiponectin, apelin, and retinol-binding protein-4, are potentially involved in the development of complicated clinical symptoms associated…Abstract Number: 1505 • 2012 ACR/ARHP Annual Meeting
Inactivation of Tankyrases Ameliorates Canonical Wnt Signaling and Prevents Experimental Fibrosis
Background/Purpose: Systemic sclerosis (SSc) is characterized by aberrant activation of fibroblasts with increased release of extracellular matrix components. Canonical Wnt signaling has recently emerged as…Abstract Number: 1506 • 2012 ACR/ARHP Annual Meeting
Primary Human Scleroderma Dermal Endothelial Cells Exhibit Defective Angiogenesis
Background/Purpose: Angiogenesis, the formation of new blood vessels, plays a critical role in a number of pathological processes including systemic sclerosis (scleroderma, SSc). SSc is…Abstract Number: 1507 • 2012 ACR/ARHP Annual Meeting
Propylthiouracil Reduces Fibrosis in Chronic Oxidant Stress Mouse Model of Scleroderma
Background/Purpose: Systemic sclerosis (SSc) is characterized by fibrosis of skin and visceral organs; vascular damage and resultant ischemia; and immunological dysregulation manifested by autoantibodies. Hypothyroidism,…Abstract Number: 1508 • 2012 ACR/ARHP Annual Meeting
Simvastatin Attenuates Pulmonary Fibrosis in a Murine Model of Systemic Sclerosis
Background/Purpose: Simvastatin is best known for its antilipidemic action due to its inhibition of 3-hydroxy-3-methylglutaryl CoenzymeA (HMG CoA) reductase. Inhibition of biological precursors in this pathway also…Abstract Number: 1509 • 2012 ACR/ARHP Annual Meeting
Correlates of Skin Gene Expression Profile in Systemic Sclerosis
