Oxidative stress-induced immunosuppression could be due to a decrease in CD4 + T lymphocyte activation or proliferation. 4-Hydroxynonenal (HNE), an end product of lipid peroxidation, and its protein adducts act as markers of oxidative stress. In...
Alcoholic liver disease (ALD) ranks among the major causes of morbidity and mortality in the world and effects millions of patients each year. Progression of ALD is well characterized and is actually a spectrum of liver diseases, which progresses...
The lipid aldehydes, 4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are reactive α,β-unsaturated aldehydes generated during the peroxidation of lipids and are implicated in the pathogenesis of several oxidative-stress mediated diseases,...
The chaperone heat shock protein 90 (Hsp90) regulates physiologically and
pathological cellular processes, by binding and stabilizing kinases involved in basal
cellular functions and in cellular responses to stress, respectively. I hypothesize...
Background The anthracycline doxorubicin (DOX) is widely used as an effective antineoplastic drug. Cardiotoxicity leading to congestive heart failure is the primary factor limiting the clinical use of DOX. However, although a variety of approaches...
This thesis is divided into two parts below. Part I Adriamycin (ADR) can produce nephrotoxicity in rodents. The underlying mechanism may relate to ADR induced oxidative stress. In this study, we used transgenic mice (NMT3), which over-expressed the...
Monophosphoryl Lipid A (MPLA), a derivative of LPS endotoxin, is a TLR4 agonist that displays as little as 0.1-1% as much toxicity as its parent molecule while retaining immunostimulatory properties. We discovered that MPLA activates a TRIF-biased...
It has been estimated that 30% of all cancer deaths in the U.S. are associated with obesity. It is well-established that obesity promotes low-grade chronic inflammation, however the mechanisms by which obesity-induced chronic inflammation may...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Pancreatic beta cells are extremely vulnerable to destruction by Reactive Oxygen Species (ROS). In type 1 diabetes and islet transplantation ROS are thought to be involved in the loss of beta cells. To test the role of antioxidant in islet...
In today's world of private information and mass communication, there is an ever increasing need for new methods of maintaining and protecting privacy and integrity of information. This thesis attempts to combine the chaotic world of cellular...
Myocardial infarction; Glucose--Metabolism; Mitochondrial DNA
Heart failure is a leading cause of morbidity and mortality in the USA. During the development of heart failure, many cardiac parameters change at the same time including fuel metabolism, oxidative stress and mitochondrial function. Each of these...
Background. Progression of alcoholic liver disease (ALD) is associated with an increase in fibrin extracellular matrix (ECM) and inflammation. Previous studies have shown that this accumulation of fibrin in ALD is mediated by impaired fibrinolysis....
c-Myc dysregulation is one of the most common abnormalities found in human cancer. MicroRNAs (miRNAs) are functionally intertwined with the c-Myc network as multiple miRNAs are regulated by c-Myc, while others directly suppress c-Myc expression. In...
Pancreatic islet transplantation is a very promising treatment for type I diabetes. Many clinical trials have failed due to early islet loss and immune rejection. Reactive oxygen species (ROS) have been demonstrated to be involved in graft damage...
O -linked β-N-acetylglucosamine ( O -GlcNAc) is an inducible, dynamically cycling, and reversible post-translational modification of serine/threonine amino acid residues of nucleocytoplasmic and mitochondrial proteins. O -GlcNAc transferase (OGT)...
Heart failure is the most frequent cause of mortality in western countries. Currently, there is no cure treatment for heart failure and the long term survival rate following heart failure is poor, with one third of patients dying within a year of...
Unrepaired DNA damage poses a serious threat to the genetic stability of a replicating cell. One mechanism of tolerating this damage is translesion DNA synthesis (TLS), in which an accessory polymerase synthesizes DNA directly across from a damaged...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
Drug delivery systems; Curcumin--Therapeutic use--Administration
Curcumin, a plant derived compound has shown significant potency against various chronic diseases like cancer in cell culture and animal studies. However, the introduction of this compound into clinical setting is limited by its poor oral...
