The Role Of Nicotine, A7 Nicotinic Acetylcholine Receptors And Extracellular Matrix Remodeling In Pulmonary Fibrosis., Glenn Ward Vicary

The median survival for idiopathic pulmonary fibrosis (IPF) patients from diagnosis is a dismal 3 years. This condition is characterized by pulmonary fibroproliferation and excess production and disordered deposition of extracellular matrix (ECM) proteins resulting in obliteration of the original tissue architecture, loss of lung function and eventual death due to respiratory failure. The main hindrance to the development of effective treatments against pulmonary fibrosis is the late detection of its progression and is often of unknown cause. Tobacco smoke represents the most important environmental factor linked to the development of pulmonary fibrosis, with over 60% of IPF patients current …
Role Of Microrna-21 In Atherogenesis., Rihab Hamed-Berair
Role Of Microrna-21 In Atherogenesis., Rihab Hamed-Berair
Electronic Theses and Dissertations
MicroRNA-21 (miR-21) is an evolutionarily conserved microRNA, abundant in most cardiovascular tissues. It has been implicated in the pathogenesis of several cardiovascular diseases including restenosis, myocardial infarction, and heart failure. However, little is known about the contribution of miR-21 in atherosclerosis. My data show that expression of miR-21 is increased by >1.5-fold in murine atherosclerotic lesions and by 1.5-2.0-fold in the macrophages of Western diet (WD)-fed LDLR-KO mice (for 12-20 weeks). In vitro, LDL, oxidized LDL, acetylated LDL and LPS induced miR-21 by 2-4-fold and down-regulated its target protein, PDCD4, in bone marrow-derived macrophages. Basally, macrophages isolated from miR-21-KO …

Abin1 In The Pathogenesis Of Glomerulonephritis And The Novel Polocyte-Neutrophil Proinflammatory Axis., Erik Anderson Korte
Electronic Theses and Dissertations
Glomerulonephritis (GN) is the most common cause of end-stage renal disease worldwide and is characterized by deposition of immune complex, inflammation, proteinuria and podocyte damage. Immunosuppressive therapy is effective in less than 50% of patients, indicating that immunological activity is not the only relevant cause of kidney injury. While methods have been described for neutrophil-mediated immune activation, specific glomerular mechanisms for recruitment of neutrophils and development of GN have not been determined. Here I present a pathogenic mechanism for the development of GN involving a novel podocyte-neutrophil axis and reveal the importance of glomerular NF-κB inhibition by the ubiquitin binding …
