1,25-Dihydroxyvitamin D Alters Lipid Metabolism And Epithelialto- Mesenchymal Transition In Metastatic Epithelial Breast Cancer Cells, Alle Nicole Barnard

Open Access Theses

Evidence suggests that high vitamin D status (marked by serum 25-hydroxyvitamin D, 25(OH)2 D) is associated with a decreased risk of breast cancer. It has been established that 1,25-dihydroxyvitamin D (1,25(OH) 2 D) can alter glycolysis and the Krebs cycle of breast cancer cells (Jiang et al., 2010; Zheng et al., 2013) but little information is available on 1,25(OH) 2 D's alterations of lipid metabolism in breast cancer cells. Thus, the current research investigates if there was an effect of 1,25(OH) 2 D on proteins that regulate lipid metabolism in MCF10A, MCF10A-ras, MCF10CA1h, and MCF10CA1a epithelial breast cancer cells. While …

Pharmacokinetics And Toxicity Of The Novel Oral Demethylating Agent Zebularine In Laboratory And Tumor Bearing Dogs, Christopher Michael Fulkerson

Open Access Theses

The aim of this thesis is to investigate the pharmacokinetics and toxicity of the novel oral demethylating agent zebularine (zeb) in laboratory dogs and tumor bearing dogs. This thesis focuses on the application of this therapeutic strategy in dogs with naturally occurring invasive transitional cell carcinoma (InvTCC), which serve as a relevant model of the human disease.

DNA hypermethylation in the promoter region is a common epigenetic change in cancer that silences tumor suppressor genes. Zeb is an oral cytidine analog that acts as a demethylating agent. Zeb has been investigated extensively in vitro as well as in mice, rodents …
