Hk-2 Cells As A Human Model Of Glucuronide Transport, Eliza E. Robertson

Theses, Dissertations and Capstones

Glucuronidation is primarily a pathway of detoxification in most species, but many glucuronide conjugates are associated with toxicity. Numerous drugs are excreted in the urine as glucuronide conjugates. Being organic anions, it is likely that glucuronides are secreted into the urine by organic anion transporters found in renal proximal tubule cells (PTCs). Some drugs that are metabolized by glucuronidation have been shown to cause renal toxicity, yet little is known about the renal handling of glucuronide conjugates. It is hypothesized that glucuronides are transported into renal PTCs by an organic anion transporter (OAT) on the basolateral membrane of the cell. …

The Genetic And Molecular Characterization Of The Polycystic Kidney Disease-Causing Mouse Gene Bicc1, Sarah J. Price

Theses, Dissertations and Capstones

Polycystic kidney disease (PKD) is one of the most common hereditary diseases and is characterized by progressive cyst formation, substantial renal enlargement, and frequently, progression to end-stage renal disease. One way to learn more about the etiology of this disease is to study mouse models that imitate the human situation. The juvenile congenital polycystic kidney disease (jcpk) gene on mouse Chromosome 10 has been found to cause a severe, early onset form of PKD when inherited in an autosomal recessive manner (Flaherty et al., 1995). Previous genetic studies mapped the jcpk locus to a 1 cM region on mouse Chromosome …

Renal Basolateral Transport Of Glucuronides And Other Organic Anions In Rat In Vitro Models, Sarah L. Miles

Theses, Dissertations and Capstones

Glucuronidation is a common Phase II biotransformation reaction that increases the hydrophilicity, and thus elimination, of toxins, xenobiotics, and endogenous compounds. Previous studies suggest that the kidney can secrete glucuronide conjugates, but the renal transport mechanisms for glucuronide secretion have not been determined. Based on the chemical nature of glucuronide metabolites, it is hypothesized that organic anion transporter (OAT) proteins along the basolateral membrane of the renal proximal tubule promote renal accumulation of glucuronide conjugates. The purpose of this study was to develop a rat renal proximal tubule model which demonstrates OAT activity and by which the contribution of OAT …

Perceptions Of Pediatric Overweight And Weight Management: A Comparison Of Parents And Physicians, Lisa K. Thomason

Masters Theses & Specialist Projects

Pediatric overweight is of paramount importance in Kentucky, as studies show prevalence rates are higher in the state than the national average. Research suggests that comprehensive treatments involving diet training, exercise training, and psychological counseling are most effective at reducing overweight in children. Little research has been done, however, to compare parents' and physicians' perceptions of obesity, its treatment, or barriers to weight management.

The purpose of this study is to examine differences in attitudes toward pediatric obesity and weight management among parents and physicians, specifically related to the importance of diet training, exercise training, and psychological counseling. Surveys were …

Pathology, East Africa

Prior to the 2001 malarial treatment policy change in Tanzania, we conducted trials to assess the efficacy of sulfadoxine-pyrimethamine (SP) and the usefulness of molecular markers in monitoring resistance. A total of 383 uncomplicated Plasmodium falciparum malaria patients (between 6 and 59 months old) were treated with SP and their responses were assessed. Mutations in the P. falciparum dihydrofolate reductase (pfdhfr) and dihydropteroate synthase (pfdhps) genes in admission day blood samples were analyzed. Results indicated that 85.6% of the patients showed an adequate clinical response, 9.7% an early treatment failure, and 4.7% a late treatment failure. The quintuple mutant genotype …

Increased Risk For Aplastic Anemia And Myelodysplastic Syndrome In Individuals Lacking Glutathione S-Transferase Genes, Joanne F. Sutton, Michael Stacey, William G. Kearns, Thomas S. Roeg, Neal S. Young, Johnson M. Liu

Bioelectrics Publications

BACKGROUND: Aplastic anemia (AA) and myelodysplastic syndrome (MDS) are marrow failure states that may be associated with chromosomal instability. An absence of the glutathione S-transferase (GST) enzyme may genetically predispose individuals to AA or MDS. PROCEDURE AND RESULTS: To test this hypothesis, we determined the GSTM1 and GSTT1 genotypes in a total of 196 patients using multiplex PCR. The GSTT1 null genotype was found to be overrepresented in Caucasian, Asian, and Hispanic patients with either AA or MDS. We confirmed a difference in the expected frequency of the GSTM1 null genotype in Caucasian MDS patients. The double null GSTM1/GSTT1 …

Department of Pathology and Laboratory Medicine

Background: The biological potential of prostate cancer is extremely variable. Particular interest is focused on markers not expressed in normal prostatic tissues. pS2 protein expression has been demonstrated in a range of malignant tissues in an oestrogen-independent pathway. Recently, it has been demonstrated that pS2, in prostate cancer, is closely associated with neuro-endocrine differentiation. In the present study, we have analyzed, the potential of Neuro-endocrine and pS2 (TFF1) expression in human prostate cancer determined by immunohistochemistry, in primary adenocarcinoma of the prostate and attempted to correlate this with the clinico-pathologic features of the patient and neuroendocrine expression.

Methods: Ninety-five malignant …

Cd46-Mediated Transduction Of A Species D Adenovirus Vaccine Improves Mucosal Vaccine Efficacy, Zenaido T. Camacho, Mallory A. Turner, Michael A. Barry, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

The high levels of preexisting immunity against Adenovirus type 5 (Ad5) have deemed Ad5 unusable for translation as a human vaccine vector. Low seroprevalent alternative viral vectors may be less impacted by preexisting immunity, but they may also have significantly different phenotypes from that of Ad5. In this study we compare species D Ads (26, 28, and 48) to the species C Ad5. In vitro transduction studies show striking differences between the species C and D viruses. Most notably, Ad26 transduced human dendritic cells much more effectively than Ad5. In vivo imaging studies showed strikingly different transgene expression profiles. The …

Determination Of The Optimal Form Of A Dna Vaccine To Induce An Effective Immune Response Against A Murine B-Cell Lymphoma, Deepti Aurora

All-Inclusive List of Electronic Theses and Dissertations

Tumor vaccines are a promising alternative to chemotherapy for the treatment of cancer. To be effective and safe, a cancer vaccine should specifically target antigens expressed only on tumor cells. The B-cell tumor-derived Ig receptor may be considered a model tumor antigen for cancer vaccine development. Specifically the immunoglobulin idiotype (ld) encoded by the variable region genes (VH and VL) provides a target antigen. Promising results have been obtained in clinical studies of ld vaccination using ld proteins. However, ld protein is laborious and time-consuming to produce. Gene-based vaccines, on the other hand, are inexpensive and offer ease of manipulation …
