Development Of A Yeast-Based Assay For The Functional Characterization Of Fkbp52/ Î?-Catenin Interactions With The Androgen Receptor, Theresa Anne Rodriguez

Open Access Theses & Dissertations

Prostate cancer development is uniquely dependent on the androgen receptorâ??s (ARâ??s) transcriptional regulation in response to hormone binding. Current therapies directly target AR acting as an antagonist at androgen binding sites. However, once androgen-dependence is lost, meaning the patient has progressed into a late-stage hormone resistant phenotype, all current treatments are essentially ineffective. Utilizing the yeast strain Saccharomyces cerevisiae we are capable of creating a model system that allows for the exogenous expression of AR while still retaining the chaperone components needed for this steroid receptor complex. The 52kDa FK506 binding protein (FKBP52) has been shown to be an important …

A Meta-Analysis Of Association Between One-Carbon Metabolism Gene Polymorphisms And Risk Of Prostate Cancer, Mahmood Tazari

Walden Dissertations and Doctoral Studies

Prostate cancer is the most common cancer among men. The purpose of this quantitative, meta-analysis study was to examine one-carbon metabolism gene polymorphisms in a group of genes to determine their association with prostate cancer risk. The genetic epidemiology theory provided the framework for the study. The data collected were from published articles. From over 2,800 individual studies, 20 articles were retained for results and data abstraction, following the title, abstract screen, and full text screening in the second phase. The data were analyzed by a meta-analysis statistical method, combining the results from selected studies to estimate the overall association. …

Dysregulation Of Micrornas In Blood As Biomarkers For Diagnosing Prostate Cancer, Rhonda W. Daniel

Theses and Dissertations

Prostate cancer is the most common noncutaneous cancer among men, yet current diagnostic methods are insufficient and more reliable diagnostic markers need to be developed. The answer that can bridge this gap and enable more efficient diagnoses may lie in microRNAs. These small, single stranded RNA molecules impact protein expression at the translational level and regulate important cellular pathways. Dysregulation of these small RNA molecules can have tumorigenic effects on cells and lead to many types of cancers.

Currently the Prostate-Stimulating Antigen (PSA) is used as a diagnostic marker for prostate cancer. However, many factors can elevate PSA levels such …
