Epigenetic Modifications Associated With Aortic Remodeling In Hyperhomocysteinemia., Nithya Narayanan
Epigenetic Modifications Associated With Aortic Remodeling In Hyperhomocysteinemia., Nithya Narayanan
Electronic Theses and Dissertations
Background: Hyperhomocysteinemia (HHcy) is prevalent in hypertensive patients and is an independent risk factor for aortic pathologies. HHcy is known to cause an imbalance between matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) leading to accumulation of collagen in the aorta resulting in stiffness and development of hypertension. Although the exact mechanism of extracellular matrix remodeling (ECM) is unclear, emerging evidence implicates epigenetic regulation involving DNA methylation. The purpose of the study was to investigate whether inhibition of DNA methylation reduces high blood pressure by regulating aortic ECM remodeling in HHcy. Methods: In the first set of experiments, we …
Myocyte-Specific Overexpression Of Stromal Cell-Derived Factor 1 Facilitates Cardiac Regeneration And Improves Myocardial Function After Infarction In Mice., Detlef Ernst-Rudolf Obal
Myocyte-Specific Overexpression Of Stromal Cell-Derived Factor 1 Facilitates Cardiac Regeneration And Improves Myocardial Function After Infarction In Mice., Detlef Ernst-Rudolf Obal
Electronic Theses and Dissertations
Background: Interruption of cardiac stromal cell-derived factor 1 (SDF1)-CXCR4 axis by chronic AMD3100 administration increased myocardial injury after permanent coronary artery ligation, demonstrating the important role of this chemokine in cardiac regeneration. Hypothesis: Cardiomyocyte-specific conditional overexpression of SDF prevents heart failure after permanent coronary ligation and facilitates cardiac regeneration. Methods and Results: Tetracycline-controlled, a-myosine heavy chain promoter directed overexpression of cardiac SDF resulted in a significant increase of SDF expression (SDF: 8.1 ng / g protein) compared with littermate WT mice (0.02 ng / g protein) four weeks after doxycycline withdrawal. SDF overexpression increased AKT and casein kinase 1 levels …

The Anti-Obesogenic Effects Of Nitric Oxide., Brian Edward Sansbury 1985-
Electronic Theses and Dissertations
Obesity is a strong risk factor for developing type 2 diabetes and cardiovascular disease and has quickly reached epidemic proportions with few tangible and safe treatment options. While it is generally accepted that the primary cause of obesity is energy imbalance, i.e., more calories are consumed than are utilized, understanding how caloric balance is regulated has proven a challenge. Molecular processes and pathways that directly regulate energy metabolism represent promising targets for therapy. In particular, nitric oxide (NO) is emerging as a central regulator of energy metabolism and body composition. NO bioavailability is decreased in animal models of obesity and …
Inflammation-Resolving Lipid Mediators Promote Revascularization To Enhance Wound Healing., Michael Jingyuan Zhang
Inflammation-Resolving Lipid Mediators Promote Revascularization To Enhance Wound Healing., Michael Jingyuan Zhang
Electronic Theses and Dissertations
Wound healing is a highly concerted cellular process that begins with inflammation and proceeds to resolution to revascularize the site of injury. Although inflammation is essential to revascularization during wound healing, it is now recognized that resolution is an active process that is equally important. Other investigations have implicated a beneficial effect of resolving inflammation and promoting resolution in the remission of inflammatory pathologies. Recently investigations have yielded a novel class of ?-3 fatty acid derived lipid mediators, biosynthesized by leukocytes, which are capable of resolving inflammation and promoting resolution. We therefore hypothesized that these leukocyte-derived pro-resolving lipid mediators can …
