RNA-Seq and Mir-Seq Analysis of SSc Skin Across Intrinsic Gene Expression Subsets Shows Differential Expression of Non-Coding RNAs Regulating SSc Gene Expression
Background/Purpose: Systemic sclerosis (SSc) is an autoimmune disease with a heterogenous and complex phenotype. Previously, our lab has identified four gene expression subsets (fibroproliferative,…Abstract Number: 771 • 2014 ACR/ARHP Annual Meeting
Development of a Bifluorescent Lineage Tracker Reporter Mouse Strain to Analyze the Phenotypic Conversion of Endothelial Cells into Myofibroblasts in Vivo. Application to Study the Synergistic Effects of Endothelin-1 on TGF-β1-Induced Endothelial-to-Mesenchymal Transition
Background/Purpose: Endothelial-to-mesenchymal transition (EndoMT) may be a crucial pathway in generating activated myofibroblasts, cells that play a pivotal role in the development of tissue and…Abstract Number: 770 • 2014 ACR/ARHP Annual Meeting
Detection of Proteins in Lung Tissues of Patients with Systemic Sclerosis Using Tissue Microarrays
Background/Purpose: Research on systemic sclerosis (SSc)-associated interstitial lung disease (ILD) has been hindered by the paucity of lung tissues, as SSc patients with lung involvement…Abstract Number: 768 • 2014 ACR/ARHP Annual Meeting
Transforming Growth Factor Beta Induces anti Angio and Vasculo-Genesis Phenotype in Dermal Fibroblasts through Secretion of Pigment Epithelium Derived Factor
Background/Purpose: Systemic Sclerosis (SSc) is an autoimmune disorder characterized by tissue fibrosis and vasculopathy. A proteomic analysis of the secretome of SSc dermal fibroblasts (SSc-FBs)…Abstract Number: 769 • 2014 ACR/ARHP Annual Meeting
Anti-Fibrotic Effects of an Investigational Drug: Bis-Oxetanyl Sulfoxide
Background/Purpose: The hallmark of pulmonary fibrosis is thickening and scarring of the tissue caused by increased deposition of extracellular matrix (ECM) proteins like collagen…Abstract Number: 767 • 2014 ACR/ARHP Annual Meeting
The Impact of Plasmacytoid Dendiritc Cells (pDCs) on Fibrosis in bleomycin–induced Murine Model of Systemic Sclerosis (SSc)
Background/Purpose Pathogenesis of systemic sclerosis (SSc) remains unclear. Alterations in adaptive and innate immune responses, with increased T-cells that produce type 2 cytokines and impaired…Abstract Number: 766 • 2014 ACR/ARHP Annual Meeting
Endothelial Fli1 Deficiency Delays Wound Healing Due to Impaired Anastomosis of Newly Formed Vessels – a Possible Mechanism of Refractory Skin Ulcers in Systemic Sclerosis
Background/Purpose Systemic sclerosis (SSc) is a multisystem inflammatory and vascular disease resulting in fibrosis of the skin and certain internal organs. Although the pathogenesis of…Abstract Number: 765 • 2014 ACR/ARHP Annual Meeting
Gene-Gene Interaction of IRF5 and BLK Polymorphisms in US and Spanish Cohorts of Systemic Sclerosis (SSc)
Background/Purpose Systemic sclerosis (SSc) is a complex autoimmune disease and several genetic loci increasing SSc susceptibility have been identified with small to modest effect sizes.…Abstract Number: 764 • 2014 ACR/ARHP Annual Meeting
ERG and FLI1 in Systemic Sclerosis-Associated Pulmonary Complications
Background/Purpose: Pulmonary arterial hypertension (PAH) and pulmonary fibrosis (PF) are the two major lung complications associated with the autoimmune disease systemic sclerosis (SSc), and constitute…Abstract Number: 763 • 2014 ACR/ARHP Annual Meeting
Caveolin-1 and Peroxisome Proliferator-Activated Receptor Gamma Co-Regulate the Differentiation of Monocytes to Adipocytes and Myofibroblasts in Vivo and in Vitro
Background/Purpose Skin fibrosis in scleroderma is associated with the loss of subcutaneous adipose tissue (lipodystrophy). The mechanisms underlying lipodystrophy and its relationship to fibrosis are…Abstract Number: 762 • 2014 ACR/ARHP Annual Meeting
IQGAP1 Enhances Contractility of Scleroderma Lung Fibroblasts and Promotes Bleomycin-Induced Pulmonary Fibrosis
Background/Purpose Scleroderma associated interstitial lung disease (SSc-ILD) is an irreversible and progressive complication and a leading cause of death among SSc patients. Constitutive overexpression of…
