Evidence For P53-Mediated Induction Of Wrap53a In Response To Dna Damage, Anne Shelton Hucks

Theses and Dissertations

p53 is a powerful tumor suppressor mutated in approximately half of all cancers. Its mRNA is stabilized post-transcriptionally via complementary base pairing with the transcript of its antisense gene, WRAP53α; without this interaction, p53 protein cannot accumulate enough to carry out its many functions related to apoptosis, cell cycle arrest, and DNA damage repair. Previous studies have shown that WRAP53α is induced in response to DNA damage. The purpose of this study was to determine which transcription factors might be responsible for this induction. After identifying three putative p53 binding sites on the WRAP53α promoter, we used chromatin immunoprecipitation …

Synthetic Lectins, A Diagnostic And Prognostic Tool For Detecting Glycans In Breast Cancer, Daniel James Gordon

Theses and Dissertations

Cancer diagnostic tools have been pushed to the forefront of medical research because a person’s chance of survival is directly correlated with how early the tumor is identified and treatment is begun. In searching for the subtle differences between healthy and tumor cells, almost every type of cancer has been shown to under, over, or neo express glycans, and these changes in the glycan fingerprint can continue as the disease progresses. This provides a powerful diagnostic opportunity that’s works by screening for glycoproteins and glycosylation patterns that deviate from normal cells.

The Regulation Of Skeletal Muscle Fatigue During The Progression Of Cancer Cachexia, Brandon N. Vanderveen

Theses and Dissertations

Cachexia is the unintentional loss of body weight secondary to chronic disease and is prevalent is roughly 50% of cancer patients. The loss of body weight and skeletal muscle mass is reduced functional capacity associated with reduced life quality. The etiology of cachexia is multimodal and complex; however, cachexia has been linked to several systemic (e.g. chronic inflammation, hypogonadism, anemia, insulin resistance) and behavioral (e.g. anorexia, inactivity) changes that can compound to accelerate muscle mass and body weight loss. While several inflammatory cytokines are associated with cachexia’s disease progression, our laboratory has established that Interleukin-6 (IL-6) is a key regulator …

Exploring Patient Perceptions And Misconceptions: Beliefs Regarding Hereditary Cancer, Margaret Flach

Theses and Dissertations

Many patients who enter a genetic counseling session have preconceived notions about why they or their family members developed a genetic condition. Often these perceptions are deeply rooted in personal, familial, and/ or cultural beliefs; individuals typically have a personal framework, or schema, into which they incorporate new information. There is limited research on what information patients are retaining during a genetic counseling session and how they are assimilating that knowledge into their existing views. We attempted to characterize these patient perceptions with respect to hereditary cancer, in order to assess how patients are adopting the information presented in a …
