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...
N-acetyltransferase 1 (NAT1) is a phase II metabolic enzyme responsible for the biotransformation of aromatic and heterocyclic amine carcinogens such as 4-aminobiphenyl (ASP). NAT1 catalyzes N-acetylation of arylamines as well as the 0-acetylation...
Mucin 1 (MUC1) is a plasma membrane-bound glycoprotein that plays a protective role in corneal epithelial cells. Two full-length splice variants of MUCl: MUCl/B and MUCl/A, that differ by the inclusion of 27 bp from intron 1 and a SNP in MUCl/A,...
Chlamydia trachomatis is an obligate intracellular pathogen that utilizes a type III secretion system to enter mammalian cells and establish an intracellular niche. TARP, the translocated actin recruitment protein, is a chlamydial invasion protein...
This dissertation is a hypothesis-driven research oriented study to determine the role of the pituitary-tumor transforming gene (PTTG) in ovarian cancer, specifically if it is involved in neoplastic transformation leading to tumorigenesis through...
Periodontitis is a chronic, destructive inflammatory disease of the supporting
tissues of the teeth with a high prevalence among adults. While the complete
pathogenesis of periodontitis remains unclear, it is initiated and sustained by...
MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level by repressing translation or stimulating mRNA degradation. In this study, I tested the hypothesis that miRNAs are differentially expressed in antiestrogen-sensitive MCF-7...
The pulvinar is the largest nucleus of the human dorsal thalamus and is affected in a variety of brain disorders, such as schizophrenia. The experiments described in this dissertation elucidate key features of tecto-pulvino-cortical pathways as a...
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...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
Vascular injury and chronic arterial diseases such as atherosclerosis and restenosis result in exposure of vascular smooth muscle cells (VSMCs) to increased concentrations of growth factors triggering a change from a contractile to a synthetic...
Pituitary tumor transforming gene ( PTTG ), also known as securing, is a novel oncogene that is expressed at high levels in most of the tumors analyzed to date. Overexpression of PTTG in mouse fibroblast(NIH 3T3) cells increases cell proliferation,...
Congenital stationary night blindness 1 (CSNBl) is a genetic disorder characterized in humans by night blindness, low visual acuity and myopia. CSNB 1 is caused by defects in genes that are involved in signaling between photoreceptors and...
Griffithsin (GRFT) is a carbohydrate binding protein derived from the red alga Griffithisia sp. that has been shown to effectively interfere with the cellular attachment and infectivity of a number of viruses, including HIV-1. However, it is...
While investigating estrogen response element (ERE) binding properties of Erα in de-identified human breast cancer extracts, additional proteins were observed that recognized ERE sequences (ERE-BP). In order to unravel the apparent role of these...
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...
Human arylamine N-acetyltransferase (NAT) is a phase II cytosolic enzyme that occurs as two isozymes, NAT1 and NAT2. This family of polymorphic enzymes catalyzes the detoxification and/or activation of many aromatic and heterocyclic amine drugs and...
Night vision--Genetic aspects; Vision disorders--Genetic aspects
Mutations in the NYX gene, encoding the novel protein nyctalopin, cause human congenital stationary night blindness type 1 (CSNB1). CSNB1 is an X-linked recessive condition and is identified by a loss of the electroretinogram (ERG) b-wave while the...
Background: Helicobacter pylori (Hp) establishes life-long gastric infection in billions of humans, and is often responsible for diseases such as peptic ulcer and gastric cancer. Cumulative actions of genetic drift and natural selection over...
Arylamine N-acetyltransferase 1 (NAT1) and 2 (NAT2) catalyze the detoxification and/or activation of aromatic and heterocyclic amine carcinogens by two pathways. This metabolism reaction can lead to the detoxification by Nacetylation, or...
