Prostate cancer is the most common male malignancy and the second leading cause of cancer related death in the United States. Despite recent advances in the detection, diagnosis, and treatment of prostate cancer, there is a need for more effective therapies. Unfortunately, most conventional therapeutic modalities, such as androgen ablation therapy, frequently result in androgen-independent cancers. These cancers are typically more aggressive, metastatic, and resistant to chemotherapeutic agents than androgen-dependent prostate cancer. Therefore, agents that are effective against both androgen-sensitive and androgen-independent, as well as genetically diverse cancers are critically needed. The objective of the dissertation research was to address …

Brms1 Coordinately Regulates Microrna To Suppress Breast, Mick D. Edmonds

The majority of cancer related mortality is attributed to complications associated with metastatic disease. Breast cancer metastasis suppressor 1 (BRMS1) suppresses metastasis of multiple cancer types in vivo and loss of nuclear BRMS1 is associated with ER-negative cancers and a high rate of proliferation. Many groups have shown BRMS1 to regulate the expression of multiple metastatic genes, yet until now no one has been able to account for how these many changes in gene expression occur. In this work, we report that BRMS1 regulates a select set of genes called microRNA (miRNA), and these miRNA themselves can regulate metastasis. Using …

Glioma-associated oncogene homolog 1 (Gli1) is a well-known oncogene and a transcription factor that mediates several signaling pathways important for tumor progression, such as hedgehog, TGFß, Ras, and EGFR. Although Gli1 is known to play an important role in cancers of brain, skin, prostate, and the pancreas, the role of Gli1 in breast cancer was not previously well-defined. Therefore, this dissertation focuses on defining the role of Gli1 and the mechanism underlying Gli1-mediated transcription in breast cancer. Interestingly, the major findings of the dissertation clearly indicate that Gli1 promotes cell survival and is predictive of a poor outcome in Estrogen …
The Effects Of Weight Reduction On Obesity-Related Cancer Biomarkers And In Vitro Cancer Cell Growth, Maria Azrad
The Effects Of Weight Reduction On Obesity-Related Cancer Biomarkers And In Vitro Cancer Cell Growth, Maria Azrad

Obesity increases the risk for breast and endometrial cancers while weight loss reduces the risk for these cancers. One aim of this dissertation was to determine the effects of weight loss from an overweight state [body mass index (BMI) 27-30] to a normal weight state on several obesity-related cancer biomarkers in African-American (AA) and European-American (EA) premenopausal women. We also sought to determine whether the method of weight loss, caloric restriction alone (CR) or combined with exercise resulted in similar changes in cancer biomarkers. The biomarkers of interest were urinary estrogen metabolites, and serum adiponectin, leptin, insulin-like growth factor (IGF)-1, …
Molecular Mechanisms Of Breast Cancer Metastasis: Gap Junction Intercellular Communication And The Bone Microenvironment, Thomas Morgan Bodenstine
Molecular Mechanisms Of Breast Cancer Metastasis: Gap Junction Intercellular Communication And The Bone Microenvironment, Thomas Morgan Bodenstine
All ETDs from UAB
Metastatic disease accounts for the overwhelming majority of cancer related deaths. More specifically, breast cancer remains one of the leading causes of death in women and breast cancer cells metastasize to bone more than any other secondary site. Upon arriving within the bone microenvironment, breast cancer cells interact with bone marrow cells, leading to changes in bone biology that favor growth of the cancer cells. Additionally, some cancer cells are capable of direct cellular communication with cells at metastatic sites via dysregulation of a family of proteins known as connexins. This direct, physical communication is known as gap junctional intercellular …
Development And Validation Of A Palliative Care Needs Assessment Instrument-English/Arabic Versions (Pcna-Eav), For Use With Patients With Advanced Cancer, Susan Edith Volker

The aim of this study was to develop and translate a psychometrically valid and reliable, population-based, needs assessment instrument, the PCNA-EAV, to measure the health care and support needs of patients with advanced cancer. The cross-sectional study design combined qualitative and quantitative methods, to test instrument reliability and validity, and to examine the association between sample characteristics and health care and support needs. The 116-item, PCNA-EAV, comprised 10 domains of need: physical/functional; social; psychological/emotional; information; communication; helpful resources; financial; religious/spiritual; priority of need; and preference for care The target population was all cancer patients in the department of oncology at …

Fiber Modification Of Adenoviral Vectors For Cancer Gene Therapy, Miho Murakami

Cancer still remains a major public health concern despite improvements in primary prevention, early detection and advanced treatments. Cancer gene therapy using human adenovirus serotype 5 (HAdV-5) as a vector has been explored as a new therapeutic approach. HAdV-5 infection is initiated by binding to the coxsackie virus and adenovirus receptor (CAR), its primary cellular receptor. However, the levels and patterns of expression of CAR vary greatly in clinical tumor tissue samples, and the expression lev-els tend to decrease as the tumors progress. The low level expression of CAR in target cancer cells diminishes the utility of HAdV-5 as a …
