The Potential Role Of Ledgf/P75 In Prostate Cancer, Tracy Ruth Daniels Dec 2004

The Potential Role Of Ledgf/P75 In Prostate Cancer, Tracy Ruth Daniels

Loma Linda University Electronic Theses, Dissertations & Projects

The serum autoantibody repertoire from cancer patients is currently being exploited for the identification of tumor associated antigens (TAA) and the design of TAA arrays. Such arrays would facilitate autoantibody profiling and potentially aid in the serological diagnosis and prognosis of tumors. The goal of this study was to identify and characterize prostate-specific TAA. We observed that while the general frequency and titers of autoantibodies in PCa patients were relatively similar to those in matched controls, significant differences could be detected between the two groups in the autoantibody response to the lens epithelial-derived growth factor p75 (LEDGF/p75). LEDGF/p75 is a …


Ionizing Radiation And Endostatin Gene Therapy Against Lung Tumor, Xian Luo Jun 2004

Ionizing Radiation And Endostatin Gene Therapy Against Lung Tumor, Xian Luo

Loma Linda University Electronic Theses, Dissertations & Projects

Although many advances have been made in radiotherapy, tumor radioresistance and normal tissue damage continue to always be important issues for radiation oncologists. Numerous reports have also documented that radiation exposure increases the risk for malignancy and suppresses immune mechanisms. However, increasing evidence has suggested that anti-angiogenic therapy that targets tumor blood supply may alter abnormal tumor vasculature, thus synergizing radiotherapy. The governing hypothesis of the present study was that modification of tumor vasculature by antiangiogenic gene therapy can increase the efficacy of radiotherapy and that radiation can also improve DNA transfection efficiency by increasing expression of the administered gene. …


The Biological Burden Of Antibiotic Resistance In Staphylococcus Aureus, Natasha Samantha Dean Mar 2004

The Biological Burden Of Antibiotic Resistance In Staphylococcus Aureus, Natasha Samantha Dean

Loma Linda University Electronic Theses, Dissertations & Projects

Antibiotic resistance is a major problem. Resistance is often mediated by genes on bacterial plasmids and dissemination of resistance is commonly achieved by plasmid transfer. The mechanisms of resistance that are presently understood suggest that resistance is energetically costly. If this is generally true, resistance would reduce the fitness of cells in the absence of antibiotics. We examined the hypothesis that resistance reduces the fitness of microorganism and requires continuous selection to be maintained. To test this hypothesis, we measured the effects of plasmid-borne resistance genes on cell growth by comparing the growth rates of Staphylococcus aureus with and without …
